linear
paddle.nn.functional.linear(x, weight, bias=None, name=None)
返回
Tensor,形状为 [batch_size,∗,out_features][batch_size,∗,out_features] ,数据类型与输入Tensor相同。
import paddle
x = paddle.randn((3, 2), dtype="float32")
# x: [[-0.32342386 -1.200079 ]
# [ 0.7979031 -0.90978354]
# [ 0.40597573 1.8095392 ]]
weight = paddle.full(shape=[2, 4], fill_value="0.5", dtype="float32", name="weight")
# weight: [[0.5 0.5 0.5 0.5]
# [0.5 0.5 0.5 0.5]]
bias = paddle.ones(shape=[4], dtype="float32", name="bias")
# bias: [1. 1. 1. 1.]
y = paddle.nn.functional.linear(x, weight, bias)
# y: [[0.23824859 0.23824859 0.23824859 0.23824859]
