Client Example: N-Dimensional Convolution Backward Data
Theory
This client example demonstrates N-dimensional convolution backward data for 3D inputs, supporting multiple data types (FP16, FP32). The backward data operation computes the gradient of the input tensor with respect to the loss, given the output gradient and the weights. This is essential for training CNNs and 3D vision models.
Mathematical Formulation:
For input X, weights W, and output gradient dY:
dX = \text{ConvBwdData}(dY, W)
- Supports 3D convolution (ND can be extended).
- Utilizes implicit GEMM for efficient computation.
Algorithmic Background:
- The backward data operation is implemented as a convolution with transformed coordinates.
- Used in training pipelines for 3D CNNs, medical imaging, and volumetric data.

Key Functions
- main() (in each
.cpp):
Sets up input/output tensors, configures convolution parameters, launches the backward data kernel, and verifies the result. - Backward data kernel invocation:
Uses the Composable Kernel device API to launch convolution backward data for different data types.
Additional Details
- Supports FP16 and FP32 for 3D convolution.
- Example parameters can be adjusted in the source for different workloads.
