Классификация экзопланет (часть II построение моделей)

Это вторая и заключительная часть статьи, в которой мы рассматриваем задачу классификации экзопланет. Если предыдущая статья была больше про предобработку данных, то здесь мы будем строить модели, отбирать лучшие и экспериментировать.

P.S. некоторые моменты могут быть не понятны, поэтому лучше начать с первой части: https://habr.com/ru/articles/800999/

Итак я надеюсь что все кто хотел, посмотрели первую часть, поэтому можно начинать.

Случайный Лес

В тот раз мы отобрали признаки методом Gain, используя случайный лес, сейчас посмотрим, насколько эффективно было это делать, построив еще одну модель случайного леса.

rfi = RandomForestClassifier(max_depth=2, random_state=42)
rfi.fit(X_train[['koi_fpflag_nt', 'koi_fpflag_ss', 'koi_fpflag_co', 'koi_fpflag_ec',
       'koi_depth', 'koi_prad', 'koi_prad_err1', 'koi_prad_err2', 'koi_teq',
       'koi_insol_err1', 'koi_insol_err2', 'koi_model_snr', 'koi_steff_err1',
       'koi_steff_err2']], y_train)
rfi_pred_train=rfi.predict(X_train[['koi_fpflag_nt', 'koi_fpflag_ss', 'koi_fpflag_co', 'koi_fpflag_ec',
       'koi_depth', 'koi_prad', 'koi_prad_err1', 'koi_prad_err2', 'koi_teq',
       'koi_insol_err1', 'koi_insol_err2', 'koi_model_snr', 'koi_steff_err1',
       'koi_steff_err2']])
rfi_pred_test=rfi.predict(X_test[['koi_fpflag_nt', 'koi_fpflag_ss', 'koi_fpflag_co', 'koi_fpflag_ec',
       'koi_depth', 'koi_prad', 'koi_prad_err1', 'koi_prad_err2', 'koi_teq',
       'koi_insol_err1', 'koi_insol_err2', 'koi_model_snr', 'koi_steff_err1',
       'koi_steff_err2']])

На самом деле не очень красочно таскать с собой этот список из признаков, но я человек ленивый, увидел вывод признаков в Feature Selection, скопировал, добавил скобочки [квадратные] и вперед.

Посмотрим на метрики

metrics(y_test,rfi_pred_test)

accuracy: 0.9456351280710925
f1: 0.94831013916501
roc auc: 0.9462939057241274

А че это за функция такая может спросить читатель, который не перешел на первую часть и поленился. Не осуждаю. Это функция и вот она:

def metrics(y_true,y_pred):
    acc=accuracy_score(y_true, y_pred)
    f1=f1_score(y_true, y_pred)
    roc_auc=roc_auc_score(y_true, y_pred)
    print(f'accuracy: {acc}\nf1: {f1}\nroc auc: {roc_auc} ')

Поскольку мы будем строить больше чем несколько моделей наличие такой функции упрощает нам жизнь, инженерное решение, можно сказать)

Теперь вспомним про то, что еще мы использовали F-тест для отбора признаков, получили такой список: ['koi_fpflag_nt', 'koi_fpflag_ss', 'koi_fpflag_co', 'koi_fpflag_ec', 'koi_depth', 'koi_teq', 'koi_steff_err1', 'koi_steff_err2'] , с него просто забираем переменную X_f, которая объявлялась в коде первой части

y_f=y
X_f_train, X_f_test, y_f_train, y_f_test = train_test_split(X_f, y_f, test_size=0.2, random_state=42)
model_f=RandomForestClassifier(max_depth=2, random_state=42)
model_f.fit(X_f_train, y_f_train)
f_pred=model_f.predict(X_f_test)
metrics(y_f_test, f_pred)

accuracy: 0.9790904338734971
f1: 0.9801192842942346
roc auc: 0.9798926657489797

Пока что F-test это самое лучшее что случалось с этими данными, мне очень нравятся такие метрики, но мы на этом не остановимся.

XGBoost

мемчик с интернета для того чтобы не было скучно

Прежде чем строить модель XGBoost, прогоним его через GridSearchCV, скорее всего это произойдет относительно быстро. Я просто отмечу, что чем больше параметров вы решили прогнать, тем больше времени это займет.
GridSearchCV позволяет отобрать лучшие параметры для обучения модели, по моим ощущениям у XGBoost данная функция работает быстрее чем у Catboost, как и в принципе процесс обучения. Возможно я не прав, поэтому если у кого то есть мысли на этот счет, хотелось бы их послушать.
Запускаем процесс:

from xgboost import XGBClassifier
from sklearn.model_selection import GridSearchCV
xgbmodel = XGBClassifier()
parameters = {'learning_rate': [0.03, 0.1],
              'max_depth': [2,3.5, 10],
              'colsample_bytree': [0.7, 0.5, 1],
              'n_estimators': [0,150,10]}

xgb_grid = GridSearchCV(xgbmodel,
                        parameters,
                        cv = 2,
                        n_jobs = 5,
                        verbose=True)

xgb_grid.fit(X,y)

print(xgb_grid.best_score_)
print(xgb_grid.best_params_)

На выходе получаем такое:
Fitting 2 folds for each of 54 candidates, totalling 108 fits 0.9807611877875366 {'colsample_bytree': 1, 'learning_rate': 0.03, 'max_depth': 2, 'n_estimators': 150}

записываем эти параметры в нашу модель XGBoost

xgb=XGBClassifier(n_estimators=150, learning_rate=0.1, max_depth=2, colsample_bytree=0.7 ,randomstate=0)
xgb.fit(X_f_train, y_f_train)
metrics(y_test, xgb.predict(X_f_test))

accuracy: 0.9822268687924726
f1: 0.9831516352824579
roc auc: 0.982836728555653

Метрики лучше, чем у случайного леса, причем во всех 3-х построенных его вариациях.
Можно сверху накинуть Gain и уменьшить выборку, но как по мне 8 параметров и такие метрики это хорошее соотношение. Если у кого- то будет желание, думаю реализовать метод Gain по аналогии с Random-Forest (снова же предыдущая статья) не составит труда.

А мы делаем следующий шаг

CatBoost

Отбор параметров можно сделать и через Catboost, к тому же у него есть для этого свой метод, который еще и график прикольный строит, но вам придется ждать, а параметры XGBoost у нас уже есть и думаю никто не будет против, если мы их интегрируем в Catboost с небольшими изменениями:

from catboost import CatBoostClassifier
cat=CatBoostClassifier(n_estimators=150, learning_rate=0.1, max_depth=2,bootstrap_type='Bayesian', task_type='GPU')
cat.fit(X_f_train,y_f_train, verbose=False)
cat_pred=cat.predict(X_f_test)
metrics(y_test, cat_pred)

Метрики:
accuracy: 0.9822268687924726
f1: 0.9831516352824579
roc auc: 0.982836728555653

Итак, с точки зрения классического ML мы реализовали наиболее популярные модели и получили как и ожидалось получили лучшие метрики на моделях градиентного бустинга.

Нейросеть на tensorflow

Теперь проверим поставленный тезис в I части о том, что можно эту задачу решить через нейронную сеть.

Для начала стандартизируем данные относительно нормального распределения

mean=X_train.mean(axis=0)
std=X_train.std(axis=0)
X_train-= mean
X_train/= std
X_test-= mean
X_test/= std
#запринтим что мы сделали
print('train mean',X_train.mean(axis=0)[:5]) 
print('test mean',X_test.mean(axis=0)[:5]) 
print('train std',X_train.std(axis=0)[:5])
print('train std',X_test.std(axis=0)[:5])

std- среднеквадратичное отклонение
mean- среднее

Кстати std будет для всех равно 1 в print-е

Небольшое отступление

Для построения НС мы будем использовать tensorflow, который после версии 2.11 перестал поддерживать обучение на GPU на Windows, подробнее можно прочитать на их сайте: https://www.tensorflow.org/install/pip?hl=ru#windows-native_1
Чтобы решить данную проблему нужно установить python версии 3.9 (у меня 3.9.18), удалять текущий пайтон не нужно, но для версии 3.9 нужно создать отдельную виртуальную среду, например через miniconda, скачать CUDA и CUDNN если у вас NVidia, насчет альтернатив не знаю, так как у самого Nvidia. Все веселье с установкой состоит в том что нужно правильно подобрать версии всех этих расширений и библиотеки tensorflow. На это действительно может уйти много времени, если ранее вы ничего подобного не делали, поэтому дополнительно может помочь этот парень с ютуба, который заморочился и сделал подробную установку всех Cuda и Cudnn: https://www.youtube.com/watch?v=xTF_n1jp9n8
Однако о создании новой Venv ( виртуальной среды) он вроде не очень много говорил, поэтому тем кто ищет гугл в помощь.
Альтернатива всему этому либо обучение на CPU то есть на обычном процессоре, либо же google Colab, где можно выбрать на чем будет работать ваша среда и пользоваться плюшками сервиса. Для данной задачи их мощностей должно хватить.
Обучение на GPU явно быстрее чем на CPU, прирост в 1.5-2 раза можно получить точно.

На этом закончим отступление

Зададим параметры модели, а перед этим проверим, работает ли GPU

import tensorflow as tf 
physical_devices = tf.config.list_physical_devices('GPU')
print("Num GPUs:", len(physical_devices))
#output: 1  если gpu работает

model = tf.keras.Sequential([
    tf.keras.layers.Dense(32, activation='relu', input_shape=(X_train.shape[1],)),
    tf.keras.layers.Dense(16, activation='relu' ),
                    
    tf.keras.layers.Dense(1, activation='sigmoid')
])
model.summary()

# Model: "sequential"
# _________________________________________________________________
#  Layer (type)                Output Shape              Param #   
# =================================================================
#  dense (Dense)               (None, 32)                1376      
                                                                 
#  dense_1 (Dense)             (None, 16)                528       
                                                                 
#  dense_2 (Dense)             (None, 1)                 17        
                                                                 
# =================================================================
# Total params: 1,921
# Trainable params: 1,921
# Non-trainable params: 0
# _________________________________________________________________

Обучаем и смотрим на lossы


model.compile(optimizer='adam', loss='binary_crossentropy')

history = model.fit(X_train, y_train, epochs=16, verbose=1)

# Визуализация процесса обучения
plt.plot(history.history['loss'])
plt.xlim(-0.5,20)
plt.title('Loss')
plt.xlabel('Epoch')
plt.ylabel('Loss')
plt.show()

model loss

Воспользуемся Datageneratorом, позаимствованным у этого прекрасного автора с youtube: https://www.youtube.com/watch?v=PLlic60dgS4&list=PLkJJmZ1EJno4lRvtQjQrNNACpeMLOd-SD&index=7

В нем задается batch_size, поэтому если вы хотите получить результат поскорее, то просто увеличьте его например до 16, 32 или 48 и т.д. Качество модели упадет, но зато она быстрее построится.

import numpy as np
from tensorflow.keras.utils import Sequence


class DataGenerator(Sequence):
    def __init__(self, data, labels, batch_size=1):
        self.batch_size = batch_size
        self.data = data
        self.labels = labels
        
    def __len__(self):
        return int(np.round(len(self.data) / self.batch_size))

    def __getitem__(self, index):
        X = self.data[index * self.batch_size : (index+1) * self.batch_size]
        y = self.labels[index * self.batch_size : (index+1) * self.batch_size]

        return X, y
train_datagen = DataGenerator(X_train, y_train)
test_datagen = DataGenerator(X_test, y_test)
print(len(train_datagen))
print(len(test_datagen))

Обучим еще одну нейронку с оценкой данных на валидации

from tensorflow.keras.callbacks import ModelCheckpoint

# Создаем коллбэк для выполнения оценки на валидационных данных
checkpoint = ModelCheckpoint(filepath='best_model.h5', save_best_only=True, save_weights_only=True)
# Обучение модели с выполнением оценки на валидационных данных
history = model.fit(train_datagen, epochs=16, batch_size=100, validation_data=test_datagen, callbacks=[checkpoint])

# Загрузка лучших весов модели
model.load_weights('best_model.h5')

plt.plot(history.history['loss'], label='train loss')
plt.plot(history.history['val_loss'], label='validation loss')
plt.legend( );

Ну такое себе, видимо не сегодня, tensorflow.

Можно покрутить параметры модели и возможно выйти на неплохие метрики, но эта игра не стоит свеч.

Бонус. Isolation Forest

Казалось бы мы сделали все что можно и после градиентного бустинга можно было остановиться и сказать что модель готова, но ради интереса можно рассмотреть Isolation Forest. Это метод обучения без учителя, который используется в задачах кластеризации и поиска аномалий.

from sklearn.ensemble import IsolationForest
clf = IsolationForest(max_samples=50, random_state=0)
clf.fit(X_f)
pred=clf.predict(X_f_test)
# на выход модель выдает либо 1 либо -1, для перехода к нашим параметрам, нужно переписать значения:
pred_processed = np.where(pred == -1, 0, pred)

pred_counts = pd.Series(pred_processed).value_counts()

# Строим график
pred_counts.plot(kind='barh', color=sns.palettes.mpl_palette('Dark2'))
plt.gca().spines[['top', 'right']].set_visible(False)
plt.title('Isolation Forest')
plt.xlim(0, pred_counts.max()) 
plt.show()

zeros_count = y_test[y_test == 0].count()
ones_count = y_test[y_test == 1].count()

print("Количество нулей в y_test:", zeros_count)
print("Количество единиц в y_test:", ones_count)

Количество нулей в y_test: koi_pdisposition 894 dtype: int64
Количество единиц в y_test: koi_pdisposition 1019 dtype: int64

Можно прогнать его через метрики, но это не имеет особого смысла, ведь количество 0 в реальных данных примерно на 150-200 значений выше, чем у модели, да и в принципе подход метрик к задачам без учителя процесс сомнительный. Может быть мы получили совсем не то, что искали.

Вывод

Градиентный бустинг остается грозой Kaggle и является отличной моделью для решения данной задачи, которая справилась лучше чем НС. Причина как мне кажется в том, что данных для нейронки нужно на порядок больше и тогда она по другому заиграет и ожидание процесса обучения окупится. Я надеюсь, что последние 2 статьи заинтересовали определенный круг людей, как новичков, так и более опытных в data science, хотелось бы получить какой-то фидбэк по проделанной работе, или какие то советы по тому, как можно было бы улучшить результаты моделей.

Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet.

Writing this review is a joy. Marie has provided excellent service ever since I started working with her in early 2018. I was worried I wouldn't be able to get my coins back after they were stolen by hackers. I had no idea where to begin, therefore it was a nightmare for me. However, things became easier for me after my friend sent me to [email protected] and +1 7127594675 on WhatsApp. I'm happy that she was able to retrieve my bitcoin so that I could resume trading.

God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.

Hi. Please be wise, do not make the same mistake I had made in the past, I was a victim of bitcoin scam, I saw a glamorous review showering praises and marketing an investment firm, I reached out to them on what their contracts are, and I invested $28,000, which I was promised to get my first 15% profit in weeks, when it’s time to get my profits, I got to know the company was bogus, they kept asking me to invest more and I ran out of patience then requested to have my money back, they refused to answer nor refund my funds, not until a friend of mine introduced me to the NVIDIA TECH HACKERS, so I reached out and after tabling my complaints, they were swift to action and within 36 hours I got back my funds with the due profit. I couldn’t contain the joy in me. I urge you guys to reach out to NVIDIA TECH HACKERS on their email: [email protected]

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.
