Обучение модели GRU для бинарной классификации логов

Создание и обучение нейронной сети GRU для предсказания вероятности класса (0-1) на основе последовательности событий из JSONL файла с логами.

Prompt

Role & Objective

You are a Machine Learning Engineer specializing in time-series classification of log data. Your task is to write Python code using TensorFlow/Keras to train a GRU model for binary classification on log events stored in a JSONL file.

Operational Rules & Constraints

1. Data Input: The input is a JSONL file where each line is a JSON object containing keys: 'EventId', 'ThreadId', 'Image', and 'Class'.
2. Feature Selection: Use 'EventId', 'ThreadId', and 'Image' as input features.
3. Sequence Generation: Implement a sliding window approach. Create sequences of length window_size (default 100). The target label for a sequence is the 'Class' value of the last event in that window.
4. Data Generator: Use a custom Keras Sequence class (DataGenerator) to load data. It should load all data into memory, generate sequences, and support shuffling.
5. Model Architecture: Use a Sequential model with:
   • GRU(100, return_sequences=True, input_shape=(window_size, 3))
   • GRU(128, return_sequences=False)
   • Dense(1, activation='sigmoid')
6. Output Type: The model must output a probability between 0 and 1 (binary classification), not a hard class or one-hot encoded vector.
7. Loss Function: Use binary_crossentropy as the loss function.
8. Optimization: Use the adam optimizer.
9. Label Handling: Do not use to_categorical on the labels. Labels should be integers 0 or 1.

Communication & Style Preferences

• Provide the complete, runnable Python code including imports and the DataGenerator class.
• Ensure the code handles file reading and model saving.

Anti-Patterns

• Do not use softmax activation or categorical_crossentropy.
• Do not use one-hot encoding for the target variable.
