0. Задача обучения с учителем. Регрессия, Классификация

📌 Краткий ответ

Обучение с учителем — это постановка задачи, при которой каждый объект обучающей выборки снабжён целевым значением , и модель обучается приближать отображение $f(x) \approx y$ .
Регрессия: если $y \in \mathbb{R}$ (например, цена, температура).
Классификация: если $y \in \{1, \dots, K\}$ , то есть класс или категория (например, диагноз, категория изображения).

🔬 Подробный разбор

Общая постановка задачи

В обучении с учителем задана обучающая выборка из пар

$(x_i, y_i), \quad i = 1, \dots, n,$

где $x_i \in \mathbb{R}^d$ — вектор признаков, y_i — целевая переменная. Требуется построить алгоритм f(x) , минимизирующий ошибку предсказания.

Регрессия

Если $y_i \in \mathbb{R}$ или $\mathbb{R}^k$ , задача называется регрессией.
Модель должна предсказывать численное значение. Типичные функции потерь:

Mean Squared Error (MSE)
Mean Absolute Error (MAE)

Примеры:

Прогнозирование цены недвижимости
Оценка спроса на товар

Классификация

Если $y_i \in \{1, \dots, K\}$ — задача классификации.
В простейшем случае — бинарная классификация (например, "да/нет").
При

K > 2 — многоклассовая. Также существует multi-label классификация, когда одному объекту соответствуют несколько меток.

Модель выдает либо вероятности по классам (soft), либо сразу метку (hard). Часто оптимизируют logloss или используют surrogate-функции.

Примеры:

Распознавание рукописных цифр (0–9)
Классификация e-mail как "спам / не спам"

💻 Отрисовываем предсказания линейной и логистической регресии

Заглянем чуть дальше и покажем, пример решения задачи регресии (линейной регрессией) и классификации (логистической регрессией)

# Добавляем второй признак (среднее значение) # отрисовать только 1 признак можем => по второму усредним! 
# так делать очень плохо! но для игрушечного примера - ок!
x_grid_full = np.column_stack([x_grid, np.full_like(x_grid, X_reg[:, 1].mean())])
y_pred = reg.predict(x_grid_full)

# Визуализация регрессии

1. Метрики классификации: accuracy, balanced accuracy, precision, recall, f1-score, ROC-AUC, расширения для многоклассовой классификации

📌 Краткий ответ

Для задачи бинарной классификации ( $y \in {0, 1}$ ) можно построить матрицу ошибок и по ним посчитать метрики:

Метрика	Формула	Смысл
Accuracy	`Accuracy = (TP + TN) / (TP + TN + FP + FN)`	Общая доля правильных предсказаний
Balanced Accuracy	`0.5 * (TPR + TNR) = 0.5 * (TP / (TP + FN) + TN / (TN + FP))`	Усреднённая точность по классам при дисбалансе
Precision	`TP / (TP + FP)`	Доля верных положительных предсказаний
Recall	`TP / (TP + FN)`	Доля найденных положительных среди всех реальных
F1(b)-score	`2 * P * R / (P + R) = 2 / (1/P + 1/R) = [b=1] = (b^2 + 1) / (b^2 r^-1 + r^-1)`	Баланс между precision и recall
AUC	Доля правильно упорядоченных пар среди (Negative, Positive)	Площадь под ROC-кривой (TPR (y) vs FPR (x) при разных порогах)

Легче запомнить, как TPR = recall позитивного класса, а FPR = 1 - recall негативного класса !

Как по мне самое простое и полезное переформулировка - это доля правильно упорядоченных пар среди (Negative, Positive)

Самый плохой случай - AUC=0.5 иначе можно реверснуть!
Лучшая метрика AUC=1

Для многоклассовой классификации - считаем для каждого класса one-vs-rest матрицу ошибок. Далее либо микро-усредняем (суммируем компоненты и считаем метрку) или макро-усреднение (по классам считаем и усредняем)

🔬 Подробный разбор

Очень подробно расписано здесь!

Обратите внимание так же на:

Recall@k, Precision@k
Average Precision

2. Метрики регрессии: MSE, MAE, R²

📌 Краткий ответ

Метрика	Формула	Смысл
MSE	`mean((y_true - y_pred) ** 2)`	Среднеквадратичная ошибка. Наказывает большие ошибки сильнее.
MAE	`mean(abs(y_true - y_pred))`	Средняя абсолютная ошибка. Интерпретируется в исходных единицах.
R² score	`1 - MSE_model / MSE_const`	На сколько лучше константного предсказания(=среднее при минимизации MSE) . От 0 до 1 (может быть < 0 при плохой модели).

🔬 Подробный разбор

MSE (Mean Squared Error)
Наиболее распространённая функция потерь. Ошибки возводятся в квадрат, что делает метрику чувствительной к выбросам.
MSE = mean((y - ŷ) ** 2)

MAE (Mean Absolute Error)
Абсолютное отклонение между предсказаниями и истиной. Менее чувствительна к выбросам(=робастнее), хорошо интерпретируется (в тех же единицах, что и целевая переменная).
MAE = mean(|y - ŷ|)

Huber Loss — гибрид между MSE и MAE: локально квадратичный штраф, дальше линейный.

R² (коэффициент детерминации)
Показывает, какую часть дисперсии целевой переменной объясняет модель.
R² = 1 - (MSE_model / MSE_const)
Где MSE_const — ошибка наивной модели, предсказывающей среднее.

3. Оценка максимального правдоподобия (MLE), связь с регрессией и классификацией

📌 Краткий ответ

MLE (Maximum Likelihood Estimation) — метод оценки параметров, при котором максимизируется вероятность наблюдаемых данных.

Целевая переменная (и параметры модели) рассматриваются как слуайные величины.

Фиксируем класс моделей (например линейные) и ищем максимально правдоподобную модель среди них (=> нужно определить вероятность наблюдаемого семпла и при выводк воспользоваться независимостью семплов)!

В линейной регрессии (при нормальном шуме) MLE ⇔ минимизация MSE
В логистической регрессии MLE ⇔ минимизация логлосса
Регуляризация вносит априорные предположения (MAP) на веса. При нормальном, получаем регуляризацию, при лаплассе .

🔬 Формальные выводы

Детальнее можно узнать в конце тетрадке.

✍ MLE и линейная регрессия

Предполагаем, что целевая переменная yᵢ имеет нормальное распределение с центром в xᵢᵀw и дисперсией σ²:

$y_i \sim \mathcal{N}(x_i^\top w, \sigma^2)$

Тогда правдоподобие всей выборки:

$p(y | X, \theta) = \prod_i \mathcal{N}(y_i | x_i^\top w, \sigma^2)$

Берём логарифм:

$\log p(y | X, \theta) = \sum_i \log \left( \frac{1}{\sqrt{2\pi} \sigma} \exp\left( -\frac{(y_i - x_i^\top w)^2}{2\sigma^2} \right) \right)$

Раскрываем сумму:

$= \sum_i \left( -\frac{1}{2} \log(2\pi) - \log \sigma - \frac{(y_i - x_i^\top w)^2}{2\sigma^2} \right)$

→ максимизация логарифма правдоподобия эквивалентна минимизации:

$\sum_i (y_i - x_i^\top w)^2$

✅ Вывод:

Метод максимального правдоподобия (MLE) для линейной регрессии приводит к функции потерь MSE — среднеквадратичной ошибке.

Регуляризация (например, Ridge(=)) возникает при добавлении априорного распределения на веса — это уже MAP, не MLE.

✍ MLE и логистическая регрессия

В бинарной классификации целевая переменная yᵢ ∈ {0, 1} - для отклонения используем распределние Бернули.

Предполагаем:

$P(y_i = 1 | x_i, w) = \sigma(x_i^\top w) = \frac{1}{1 + e^{-x_i^\top w}}$

Правдоподобие всей выборки:

$L(w) = \prod_i \left[ \sigma(x_i^\top w) \right]^{y_i} \cdot \left[ 1 - \sigma(x_i^\top w) \right]^{1 - y_i}$

Логарифм правдоподобия:

$\log L(w) = \sum_i \left[ y_i \log \sigma(x_i^\top w) + (1 - y_i) \log (1 - \sigma(x_i^\top w)) \right]$

✅ Вывод:

Максимизация логарифма правдоподобия ⇔ минимизация log-loss (логистической функции потерь)

✍ Что меняется с регуляризацией: MAP (Maximum A Posteriori)

Добавим априорное распределение на параметры:

L2-регуляризация ⇔ априорное w ∼ 𝒩(0, λ⁻¹I)
L1-регуляризация ⇔ априорное w ∼ Laplace(0, b)

MAP-оценка:

$\log P(w | X, y) ∝ \log L(w) + \log P(w)$

→ Это и есть MLE + регуляризация:

MLE ⇔ логлосс
MAP ⇔ логлосс + регуляризация

💻 Баесовский вывод двух нормальных распределений

Задача

Пусть параметр неизвестен и:

Prior: $w \sim \mathcal{N}(\mu_0, \sigma_0^2)$
Likelihood: $y \sim \mathcal{N}(\mu_1, \sigma_1^2)$ — наблюдение, связанное с

Найти posterior $P(w \mid y)$

📐 Шаг 1: формула Байеса

По определению:

$P(w | y) \propto P(y | w) \cdot P(w)$

Логарифмируем обе части:

$\log P(w | y) = \log P(y | w) + \log P(w) + \text{const}$

🧮 Шаг 2: подставляем нормальные распределения

Prior:

$\log P(w) = -\frac{1}{2\sigma_0^2} (w - \mu_0)^2 + \text{const}$

Likelihood (в терминах , фиксируя $y = \mu_1$ ):

$\log P(y | w) = -\frac{1}{2\sigma_1^2} (w - \mu_1)^2 + \text{const}$

📉 Шаг 3: складываем логарифмы

$\log P(w | y) = -\frac{1}{2\sigma_0^2} (w - \mu_0)^2 - \frac{1}{2\sigma_1^2} (w - \mu_1)^2 + \text{const}$

Это — квадратичная функция по , то есть логарифм нормального распределения. Следовательно, сам posterior — тоже нормальный:

$P(w | y) = \mathcal{N}(\mu_{\text{post}}, \sigma_{\text{post}}^2)$

✅ Вывод: параметры апостериорного распределения

$\sigma_{\text{post}}^2 = \left( \frac{1}{\sigma_0^2} + \frac{1}{\sigma_1^2} \right)^{-1}$ $\mu_{\text{post}} = \sigma_{\text{post}}^2 \left( \frac{\mu_0}{\sigma_0^2} + \frac{\mu_1}{\sigma_1^2} \right)$

Отрисуем!

import numpy as np
import matplotlib.pyplot as plt
from scipy.stats import norm

# Ось параметра w
w = np.linspace(-5, 5, 500)

# Заданные параметры
mu0, sigma0 = 0, 1     # prior: N(0, 1)
mu1, sigma1 = 2, 1     # likelihood: N(2, 1)

# Распределения
prior = norm.pdf(w, loc=mu0, scale=sigma0)
likelihood = norm.pdf(w, loc=mu1, scale=sigma1)

# Постериорное распределение — аналитически
sigma_post_sq = 1 / (1/sigma0**2 + 1/sigma1**2)
mu_post = sigma_post_sq * (mu0/sigma0**2 + mu1/sigma1**2)
posterior = norm.pdf(w, loc=mu_post, scale=np.sqrt(sigma_post_sq))

# Визуализация
plt.figure(figsize=(10, 6))
plt.plot(w, prior, label=f"Prior N({mu0}, {sigma0**2})", color='green')
plt.plot(w, likelihood, label=f"Likelihood N({mu1}, {sigma1**2})", color='blue')
plt.plot(w, posterior, label=f"Posterior N({mu_post:.2f}, {sigma_post_sq:.2f})", color='red')

plt.axvline(mu0, color='green', linestyle=':')
plt.axvline(mu1, color='blue', linestyle=':')
plt.axvline(mu_post, color='red', linestyle='--', label=f"MAP = {mu_post:.2f}")

plt.title("Байесовский вывод: Posterior = Prior × Likelihood")
plt.xlabel("w")
plt.ylabel("Плотность")

plt.grid(True)

plt.show()

На самом деле, даже для двух многмерных нормальных распределений с разными дисперсиями - верно следующее, их апостериальное распределение тоже нормальное!

4. Наивный байесовский классификатор

📌 Краткий ответ

Наивный байесовский классификатор предполагает, что все признаки условно независимы при фиксированном классе:

$P(y | x_1, ..., x_d) ∝ P(y) \cdot \prod_{i=1}^d P(x_i | y)$

Обучение: оцениваем P(y) и P(xᵢ | y) по каждому признаку.
Работает быстро, устойчив к малым выборкам, можно задавать разные распределения.

🔬 Подробный разбор

В логарифмической форме:

$\log P(y | x) ∝ \log P(y) + \sum_i \log P(x_i | y)$

Можно использовать:

Гауссовское распределение — GaussianNB
Ядерную оценку плотности (KDE) — сглаженные вероятности
Экспоненциальное, Лапласовское и др.

Преимущество подхода: можно подставлять разные распределения под разные признаки.

5. Метод ближайших соседей

📌 Краткий ответ

Метод k ближайших соседей (k-NN) — это ленивый классификатор, который:

не обучается явно
при предсказании ищет k ближайших объектов в обучающей выборке
голосует за класс большинства (или усредняет — в регрессии).

Работает по метрике (например, евклидовой), чувствителен к масштабу и шуму.

🔬 Подробный разбор

При классификации:

ŷ(x) = argmax_c ∑ I(yᵢ = c) для xᵢ ∈ N_k(x)

Плюсы:

не требует обучения,
хорошо работает на небольших данных.

Минусы:

не масштабируется (хранит всё),
чувствителен к размерности и шуму,
требует нормализации признаков.

Гиперпараметры:

k — число соседей (подбирается на валидации),
metric — метрика расстояния (евклидово, косинусное и т.д.)

📊 Глава 2: Почему линейная модель — это не просто прямая

6. Линейная регрессия. Формулировка задачи для случая функции потерь MSE. Аналитическое решение. Теорема Гаусса-Маркова. Градиентный подход в линейной регрессии.

📌 Краткий ответ

Линейная регрессия минимизирует MSE:

$L(w) = \|Xw - y\|^2$

Аналитически: $\hat{w} = (X^\top X)^{-1} X^\top y$
Теорема Гаусса-Маркова: это наилучшая линейная несмещённая оценка при стандартных предположениях (BLUE)
При больших данных: используется градиентный спуск

🔬 Подробный разбор

📌 Постановка задачи

У нас есть:

$X \in \mathbb{R}^{n \times d}$ — матрица признаков;
$y \in \mathbb{R}^n$ — целевая переменная;
$w \in \mathbb{R}^d$ — веса модели.

Цель: минимизировать среднеквадратичную ошибку:

$L(w) = \|Xw - y\|^2 = (Xw - y)^\top (Xw - y)$

📌 Вывод аналитического решения

Выпишем градиент по :

$\nabla_w L(w) = 2 X^\top (Xw - y)$

Приравниваем к нулю:

$X^\top (Xw - y) = 0$

Раскрываем скобки:

$X^\top X w = X^\top y$

Предполагая, что $X^\top X$ обратима:

$\hat{w} = (X^\top X)^{-1} X^\top y$

📌 Теорема Гаусса-Маркова (формулировка)

Если:

модель линейна по параметрам: $y = Xw + \varepsilon$ ;
ошибки $\varepsilon$ имеют нулевое среднее;
одинаковую дисперсию $\text{Var}(\varepsilon) = \sigma^2 I$ ;
некоррелированы между собой;

→ тогда $\hat{w}$ (из нормального уравнения) — наилучшая линейная несмещённая оценка (BLUE).

Термин BLUE (Best Linear Unbiased Estimator) — это сокращение:

Linear (линейная):
Оценка $\hat{w}$ — это линейная функция от :
$\hat{w} = A y$
где $A = (X^\top X)^{-1} X^\top$
Unbiased (несмещённая):
Среднее значение оценки совпадает с истинным параметром:
$\mathbb{E}[\hat{w}] = w$
Best (наилучшая):
Из всех линейных и несмещённых оценок, $\hat{w}$ имеет наименьшую дисперсию:
$\text{Var}(\hat{w}) \text{ минимальна среди всех линейных несмещённых оценок}$

7. Регуляризация в линейных моделях: L_1 ,L_2 их свойства. Вероятностная интерпретация.

📌 Краткий ответ

Регуляризация — это добавка к функции потерь, которая ограничивает рост весов и борется с переобучением.

L2-регуляризация (Ridge):
$\text{Loss}(w) = \text{MSE}(w) + \lambda \|w\|_2^2$
L1-регуляризация (Lasso):
$\text{Loss}(w) = \text{MSE}(w) + \lambda \|w\|_1$
L2 сглаживает и уменьшает веса
L1 приводит к разреженным решениям (обнуляет ненужные признаки)

🔬 Подробный разбор

L_2 - Ridge, L_1 - Lasso, Elastic Net - комбинация.

📌 Вероятностная интерпретация

Добавление регуляризатора эквивалентно введению априорного распределения на параметры (подробнее в 3 вопросе о MLE):

L2 = Gaussian prior:
$P(w) \sim \mathcal{N}(0, \sigma^2 I)\Rightarrow \text{MAP} \propto \log L(w) - \lambda \|w\|_2^2$
L1 = Laplace prior:
$P(w) \sim \text{Laplace}(0, b)\Rightarrow \text{MAP} \propto \log L(w) - \lambda \|w\|_1$

→ То есть регуляризация = байесовская MAP-оценка, если мы знаем prior на веса.

Почему при зануляются веса?

Очень популярный и важный вопрос! Изобразим уровни потерь по отдельности двух частей лосса!

Предпложим противное. Пусть t^* опитимум пересечения и он не на осях координат. Из-за выпуклости двух фигур, найдется пересечения внутри, а по нему можно уже подняться вверх, сохранив ошибку по L_1 и уменьшить MSE ! Второй заумный аргумент .

Упрощение 2-аргумента: две фигуры выпуклые и имеют единственную касательную (помимо L_1 в точках на осях!), тогда в точке касания можно провести разделяющую прямую!

А это значит, что оси у элипса у MSE параллельны фиксированному направлению, а вероятность таких направлений (на одну размерность меньше=) равна нулю!

💻 Сравниваем веса моделей с L1 и L2

Обучим две модельки с разными регулизаторами на данных с 8 из 10 шумных признаками. В идеали избавиться(иметь вес ноль) от всех неинформативных признаков!

8. Логистическая регрессия. Эквивалентность подходов MLE и минимизации логистических потерь.

📌 Краткий ответ

Логистическая регрессия — это модель предсказывающая вероятность класса y = 1 :

P(y = 1 | x) = \sigma(x^\top w), \quad \sigma(z) = \frac{1}{1 + e^{-z}}

MLE: максимизация логарифма правдоподобия ⇔ минимизация log-loss (обычно для бинарной классификации) = cross-entropy-loss (обычно для мультиклассовой классификации)

$\log L(w) = \sum_i y_i \log p_i + (1 - y_i) \log(1 - p_i)$

или

$\mathcal{L}(W) = - \sum_{i=1}^{n} \sum_{k=1}^{K} p_{i, k} \cdot \log \hat{p}_{i,k}$ | обычно, $p_{i_{fix}, k}$ - ровно одна 1 и остальные нули.

🔬 Подробный разбор

📌 Вывод: MLE для логистической регрессии

Обозначим:

$y_i \in \{0, 1\}$
$p_i = \sigma(x_i^\top w)$

Правдоподобие:

L(w) = \prod_i p_i^{y_i} (1 - p_i)^{1 - y_i}

Логарифмируем:

\log L(w) = \sum_i y_i \log p_i + (1 - y_i) \log(1 - p_i)

Подставляем $p_i = \sigma(x_i^\top w)$ :

И получаем логистическую функцию потерь:

\mathcal{L}(w) = - \sum_i \left[
  y_i \log \sigma(x_i^\top w) + (1 - y_i) \log(1 - \sigma(x_i^\top w))
\right]

💻 Почему сырая линейка плоха в классификации? А лог-рег хорош?

Предлагаю разобрать пример, в котором лог-рег прекрасно абсолютно предсказывает вероятности, чем линейка не может похвастаться. Иногда нужно не просто факт класса сказать, а и вероятность!

Но дальше мы узнаем о SVM, и увидим что не обязательно приводить выход модели в диапозон [0, 1] !

# Пример: класс 0 сконцентрирован в одном месте, класс 1 — сильно растянут вправо

# Класс 0 — 50 точек около x = 0
X0 = np.random.normal(loc=0, scale=0.5, size=(50, 1))
y0 = np.zeros(50)

# Класс 1 — 50 точек с растущим x (от 10 до 500)
# X1 = np.linspace(5, 25, 10).reshape(-1, 1)
X1 = np.linspace(10, 500, 10).reshape(-1, 1)
y1 = np.ones(10)

# Объединяем
X_all = np.vstack([X0, X1])
y_all = np.concatenate([y0, y1])

# Обучаем модели
linreg = LinearRegression().fit(X_all, y_all)
logreg = LogisticRegression().fit(X_all, y_all)

9. Многоклассовая классификация. Один-против-одного, один-против-всех, их свойства.

📌 Краткий ответ

One-vs-Rest (OvR): обучаем бинарных моделей «класс vs остальные», выбираем класс с макс. откликом.
One-vs-One (OvO): обучаем $\frac{K(K-1)}{2}$ моделей по парам классов, предсказание — по большинству голосов.

При предсказании инферяться все модели!
В One-vs-One не учитываются вероятности лишь факт победы.

🔬 Подробный разбор

📌 One-vs-Rest (OvR)

Обучение:

бинарных моделей , каждая отличает класс от остальных

Предсказание:

Вычисляем отклики $f_0(x), f_1(x), \dots, f_{K-1}(x)$
Выбираем класс с максимальным значением:
$\hat{y} = \arg\max_k f_k(x)$

Если модель выдаёт вероятности $P(y = k \mid x)$ , выбираем по ним.

📌 One-vs-One (OvO)

Обучение:

Строим классификаторы для всех пар классов:
$f_{i,j}(x) \text{ обучается на классах } i \text{ и } j$
Всего $\frac{K(K-1)}{2}$ моделей.

Предсказание:

Каждый классификатор голосует: $f_{i,j}(x) \in \{i, j\}$
Считаем число голосов за каждый класс
Итог:
$\hat{y} = \arg\max_k \text{(кол-во голосов за } k)$

Голоса — дискретные, уверенность моделей не используется.

10. Метод опорных векторов. Задача оптимизации для SVM. Трюк с ядром. Свойства ядра.

📌 Краткий ответ

SVM (support vector machine) — это алгоритм решает задачу классификации ("линейная классификация"), который ищет гиперплоскость, максимально разделяющую классы с зазором (margin).

Он решает задачу максимизации отступа, то есть делает так, чтобы:

все объекты лежали как можно дальше от границы (реализуется ядром, скалярным произведением сонаправленностью <, $\hat{y}$ >)
и при этом допускались ошибки для равномерного отступа (через мягкие штрафы) (реализуется добавлением зазора=константы 1 - M).
ядра можно брать разные - не обязательно линейное

Функция потерь (hinge-loss) устроена так, чтобы:

не штрафовать объекты с отступом $\ge 1$ ,
и наказывать только те, которые «лезут» в буферную зону или ошибаются (=либо неверные, либо неуверенно правильные!):

$\mathcal{L}(w) = \frac{1}{n} \sum \max(0, 1 - y_i (w^\top x_i + b)) + \frac{\lambda}{2} \|w\|^2$

Чем, же это лучше чем просто линейная регрессия в классификации? А тем, что SVM решает задачу разделить данные, а линейная регресия старается провести через них!

🔬 Подробный разбор

📌 Модель

Классификатор:

$\hat{y}(x) = \text{sign}(w^\top x + b)$

Отступ (margin):

$M_i = y_i (w^\top x_i + b)$

Чем больше M_i , тем выше уверенность в классификации.

📌 Целевая функция (hinge loss)

SVM минимизирует:

$\mathcal{L}(w) = \frac{1}{n} \sum_{i=1}^n \max(0, 1 - y_i(w^\top x_i + b)) + \frac{\lambda}{2} \|w\|^2$

Первый член — штраф за малый отступ (ошибки или «почти ошибки»)
Второй — регуляризация (контроль за нормой )

📌 Ядровой трюк (kernel trick)

Вместо линейного $x \cdot x'$ , используем:

$K(x, x') = \langle \phi(x), \phi(x') \rangle$

→ Не нужно явно строить $\phi(x)$ , а граница может быть нелинейной.

📌 Примеры ядер

Ядро	Формула
Линейное	$K(x, x') = x^\top x'$
Полиномиальное	$K(x, x') = (x^\top x' + c)^d$
RBF (Гаусс)	$K(x, x') = \exp(-\gamma \|x - x'\|^2)$

✅ Свойства допустимого ядра (ядровой функции)

Функция K(x, x') — допустимое ядро, если оно:

Симметрична:
Положительно полуопределённая (PSD):
Для любых $x_1, \dots, x_n \in \mathbb{R}^d$ и любых весов $\alpha_1, \dots, \alpha_n \in \mathbb{R}$ выполняется:
$\sum_{i=1}^n \sum_{j=1}^n \alpha_i \alpha_j K(x_i, x_j) \ge 0$
Это значит: матрица Грама на любом наборе точек — положительно полуопределённая.

Почему это важно?

Если — валидное ядро, то по теореме Мерсера:

$K(x, x') = \langle \phi(x), \phi(x') \rangle$

для некоторого отображения $\phi(\cdot)$ в (возможно бесконечномерное) пространство признаков.

→ Это делает метод SVM с ядром линейным в этом скрытом пространстве, без явного вычисления $\phi(x)$ .

I know firsthand how devastating it feels to lose money to a scam. When it happened to me, I was left frustrated, hopeless, and unsure where to turn. Complaining to apps about being scammed on their platforms didn’t change anything it felt like no one cared. But through a friend’s advice, I connected with a recovery professional who gave me real hope. With their help, I was able to get my funds back, something I thought was impossible. I’m sharing this because I don’t want anyone else to feel as lost as I once did. Whether you’ve been scammed through crypto platforms, dating scams, real-estate or mortgage fraud, or even fake ICOs, please know there’s still a way forward. If you’ve lost money, reach out to Recoveryfundprovider(@)gmail(.)com).) or (WhatsApp) at (+)44 7366445035 for consultation and recovery services.

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.

In 2022, I lost 1.5 ETH in what I thought was a promising Twitter investment. I reached out to the so-called brokers behind it, but they vanished and stopped replying. For years, I carried the heavy belief that my crypto was gone forever. Then, by chance, I discovered RecoveryFundProvider [email protected] WhatsApp at +44 736-644-5035 through a finance podcast. That moment changed everything. Their team didn’t lure me in with false promises or flashy guarantees. Instead, they explained their process clearly specializing in advanced blockchain tracing, smart contract forensics, and even transaction reversal in certain cases. Skeptical but hopeful, I allowed them to review my case. What followed was beyond my expectations. They dug deep into the blockchain ledger, followed the coin’s complex movements across multiple addresses, and even collaborated with global nodes to trace every trail. Two weeks later, I received an alert I never thought I’d see again: my crypto had been fully recovered and safely transferred back to me. I cried tears of relief. What sets RecoveryFundProvider apart isn’t just their cutting-edge expertise, but their unwavering ethics and dedication. They treat every client like more than just another case number even years after a loss. Today, I can confidently say they live up to their name, and I’m endlessly grateful.

You are one step away from recovering your lost crypto funds. CAPITAL REDEMPTION WIZARD is the solution. Without them, I would have lost everything. I was scammed through a compromised email, lured by a fake Elon Musk Bitcoin investment. After applying and completing KYC, I was credited with 2.5 Bitcoin. When I tried to withdraw, I was hit with fees, and my wallet was emptied of $103,000.00. Their support team was hostile. I researched and found CAPITAL REDEMPTION WIZARD. They recovered my hacked Bitcoin. I learned the Bitcoin offer was a scam. CAPITAL REDEMPTION WIZARD guided me through this.

In 2022, I lost 1.5 ETH in what I thought was a promising Twitter investment. I reached out to the so-called brokers behind it, but they vanished and stopped replying. For years, I carried the heavy belief that my crypto was gone forever. Then, by chance, I discovered RecoveryFundProvider ( recoveryfundprovider@gmail. com WhatsApp +44 736-644-5035) through a finance podcast. That moment changed everything. Their team didn’t lure me in with false promises or flashy guarantees. Instead, they explained their process clearly specializing in advanced blockchain tracing, smart contract forensics, and even transaction reversal in certain cases. Skeptical but hopeful, I allowed them to review my case. What followed was beyond my expectations. They dug deep into the blockchain ledger, followed the coin’s complex movements across multiple addresses, and even collaborated with global nodes to trace every trail. Two weeks later, I received an alert I never thought I’d see again: my crypto had been fully recovered and safely transferred back to me. I cried tears of relief. What sets RecoveryFundProvider apart isn’t just their cutting-edge expertise, but their unwavering ethics and dedication. They treat every client like more than just another case number even years after a loss. Today, I can confidently say they live up to their name, and i am endlessly grateful.

I ended my marriage. My spouse was unfaithful. I found clear proof of her cheating. She hid her phone activity. Many secrets were on her phone. She used different apps. I hired a private investigator. I needed solid evidence first. I did not want to accuse her without proof. That could lead to legal trouble. They helped me access her phone. They linked her phone use to mine. I could then watch her phone without her knowing. This is how I learned about her affair. I also found out she planned to take my money. She intended to leave with her new partner. If you are in a similar situation, reach out to [email protected] WhatsApp at +44 736-644-5035. Get ahead of things.
