…n.cu` to serve as the CUDA-accelerated driver for dataset loading, GPU initialization, backprop training, chat sessions, and token generation.
…ation and added new directories for CI/CD workflows and assets. Updated file structure section in README.md to reflect changes in project organization and added new directories for CI/CD workflows and assets.
Introduce foundational backpropagation gradient structures and primitive
backward operations for transformer layer components.
Key additions:
- Gradient Accumulation Structures: Define `Grads` root container and child
structs (`GradLinear`, `GradEmbedding`, `GradLayerNorm`, `GradHead`, `GradMHA`,
`GradFFN`, `GradBlock`) equipped with zero-initialization helpers.
- Activation Memory Structs: Define `SavedForward` and layer-specific intermediate
tensors needed for reverse-mode automatic differentiation.
- Primitive Backward Kernels:
- `backward_cross_entropy`: Evaluates softmax derivatives scaled by batch size ($1 / BT$).
- `backward_linear`: Computes input gradients ($dX = dOut \cdot W^T$) and
accumulates weight/bias gradients ($dW$, $db$).
- `backward_layernorm`: Implements full LayerNorm backprop incorporating mean/std
jacobian terms along sequence channels.
- `backward_relu`: Computes element-wise activation derivative masks.
…nhance comment formatting. Adjusted steps for extracting PR and comment metadata, and refined success/failure reporting. Updated PR comment checks workflow
Updated project structure section with detailed descriptions for each directory and file.
