SYS.OUT:Welcome to the Capstone. You've learned CNNs and RNNs. Now we combine them to build a system that can 'see' and 'describe' images.

1. Data Prep

Neural Networks require Tensors. We must load, normalize, and batch data using PyTorch DataLoaders.

Why do we shuffle the training data in our DataLoader?

"Theoretical knowledge of Neural Networks is useless without engineering. The Capstone bridges the gap between Jupyter Notebooks and production-ready AI applications."

1. The Multi-Modal Architecture

A true capstone goes beyond simple classification (like MNIST). It tackles real-world ambiguity by combining architectures. For instance, an Image Captioning model uses a pre-trained Convolutional Neural Network (CNN) like ResNet to extract spatial features, and feeds those features into a Recurrent Neural Network (RNN/LSTM) to generate sequential text.

2. The Training Crucible

The training loop is where math becomes magic. We utilize backpropagation to update the weights of millions of parameters. You must carefully monitor the Loss Function. If validation loss spikes while training loss drops, you are witnessing Overfitting. Mitigate this by introducing Dropout layers or Data Augmentation.

3. Deployment & Inference

A model living in a Python script isn't an app. To "Build Apps with AI", you must export your model (e.g., using ONNX) and wrap it in an API using FastAPI or Flask. The front-end client sends data, the API runs the inference block, and returns the result in JSON.

❓ Capstone FAQ & Architecture Logic

Should I use PyTorch or TensorFlow for my Capstone?

PyTorch is currently the industry standard for research and building complex, dynamic architectures (like custom RNN loops) due to its pythonic "eager execution". TensorFlow/Keras is excellent for quick, standard production pipelines. We recommend PyTorch for Capstones because it forces you to understand the underlying tensor mechanics.

How do I structure a Deep Learning Capstone repo?

A professional repository should strictly separate concerns:

  • data/ (Raw and processed datasets, excluded in .gitignore)
  • models/ (Saved .pt or .onnx weight files)
  • src/ (Modular Python scripts: dataset.py, model.py, train.py)
  • notebooks/ (Jupyter notebooks for EDA only)
  • app/ (FastAPI or Streamlit deployment code)
