Python wrappers

pylucid.nn.functional.linearfunction

Public free-function entry point for the linear op.

Thin wrapper that delegates to LinearBackward::forward. This is the symbol the pybind11 binding layer (bind_nn.cpp) and other C++ call sites use; calling it directly is equivalent to using the node's static forward.

LinearBackward : Autograd node implementing the actual forward + backward.

Parameters

xTensorImplPtr

Input tensor of shape

(\ast, K)

WTensorImplPtr

Weight matrix of shape (N, K).

bTensorImplPtr

Bias of shape (N,) (zero-length tensor when bias is disabled).

Returns

TensorImplPtr

Output tensor of shape $(\ast, N)$ .
