fully-connected layer</p> +<p>Fully-connected layer is basically a matrix-vector multiplication with bias. The matrix is the weights and the input/output vectors are the activation values. Supported {weight, activation} precisions include {8-bit, 8-bit}, {16-bit, 16-bit}, and {8-bit, 16-bit}.</p> +<p>Here we have two types of kernel functions. The basic function implements the function using regular GEMV approach. The opt functions operates with weights in interleaved formats. </p> +<h2 class="groupheader">Function Documentation</h2> +<a class="anchor" id="ga4a1521e7532a1e62d71f3b12762016e2"></a> +<div
