Linear¶ class torch.nn. Linear (in_features, out_features, bias = True, device = None, dtype = None) [source] ¶ Applies a linear transformation to the incoming data: y = x A T + b y = xA^T + b y = x A T + b. This module supports TensorFloat32. Parameters. in_features – size of each input sample. out_features – size of each output sample
