How to prevent data leakage during Python Code & Docstring Auto-Complete preprocessing?

Always perform train_test_split BEFORE fitting any normalization scaler (like StandardScaler) or categorical encoders. Fit scalers strictly on the training partition and call .transform() on validation data.

FREQUENTLY ASKED QUESTIONS (FAQS)

How do I load Python Code & Docstring Auto-Complete into a PyTorch DataLoader?

Subclass torch.utils.data.Dataset, implement __len__ and __getitem__ returning (features, target) tensor pairs, and wrap the dataset with torch.utils.data.DataLoader(dataset, batch_size=32, shuffle=True).

What neural network architecture is best for Python Code & Docstring Auto-Complete?

We recommend using Causal Decoder-only Transformer / Multi-Layer GRU with BPE Tokenizer. For tabular data, a Multi-Layer Perceptron (MLP) with BatchNorm and Dropout works best; for vision, Convolutional Neural Networks (CNNs); and for sequential text, LSTM or Recurrent Language Models.

How do I prevent data leakage during preprocessing?

Never fit scalers (like StandardScaler or Normalization transforms) on the entire dataset prior to splitting. Always execute train_test_split first, call scaler.fit_transform(X_train) on the training partition only, and use scaler.transform(X_val) on validation data.
