Frequently Asked Questions — GPT
What is GPT used for?
GPT is used to build and deploy machine learning or AI systems. It provides high-level abstractions for model architectures, data pipelines, gradient computation, and optimization — letting practitioners focus on model design rather than low-level numerical code.
How does the training loop work in GPT?
A training loop iterates over batches of data, computes forward-pass predictions, calculates loss against ground truth, runs backpropagation to compute gradients, then updates model weights with an optimizer. This repeats for multiple epochs until the model converges.
How do you evaluate a model?
Split data into train, validation, and test sets. Monitor validation metrics during training to detect overfitting (training improves but validation doesn't). Report final metrics on the held-out test set. Use task-appropriate metrics: accuracy, F1, RMSE, BLEU depending on the problem type.
How do you deploy a model to production?
Export the trained model to a serialized format (ONNX, TorchScript, SavedModel). Serve via a model server (Triton, TorchServe, TF Serving) or wrap in a REST API. Package in a Docker container. Monitor inference latency, throughput, and data drift in production.
What is overfitting and how do you prevent it?
Overfitting occurs when the model memorizes training data and fails to generalize. Prevention strategies: more training data, data augmentation, dropout layers, L1/L2 regularization, early stopping based on validation loss, or a simpler model architecture.
Who Is This For?
Data scientists, ML engineers, and AI researchers who use GPT to build, train, and deploy machine learning models or AI-powered applications.
