<dl class="section user"><dt>Model definition:</dt><dd></dd></dl>
<dl class="section user"><dt></dt><dd>The CNN used in this example is based on CIFAR-10 example from Caffe [1]. The neural network consists of 3 convolution layers interspersed by ReLU activation and max pooling layers, followed by a fully-connected layer at the end. The input to the network is a 32x32 pixel color image, which will be classified into one of the 10 output classes. This example model implementation needs 32.3 KB to store weights, 40 KB for activations and 3.1 KB for storing the <code>im2col</code> data.</dd></dl>
