+ * @defgroup CNNExample Convolutional Neural Network Example
+ *
+ * \par Description:
+ * \par
+ * Demonstrates a convolutional neural network (CNN) example with the use of convolution,
+ * ReLU activation, pooling and fully-connected functions.
+ *
+ * \par Model definition:
+ * \par
+ * 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 \c im2col data.
+ *
+ * \image html CIFAR10_CNN.gif "Neural Network model definition"
+ *
+ * \par Variables Description:
+ * \par
+ * \li \c conv1_wt, \c conv2_wt, \c conv3_wt are convolution layer weight matrices
+ * \li \c conv1_bias, \c conv2_bias, \c conv3_bias are convolution layer bias arrays
+ * \li \c ip1_wt, ip1_bias point to fully-connected layer weights and biases
+ * \li \c input_data points to the input image data
+ * \li \c output_data points to the classification output
+ * \li \c col_buffer is a buffer to store the \c im2col output
+ * \li \c scratch_buffer is used to store the activation data (intermediate layer outputs)

+ * @defgroup GRUExample Gated Recurrent Unit Example
+ *
+ * \par Description:
+ * \par
+ * Demonstrates a gated recurrent unit (GRU) example with the use of fully-connected,
+ * Tanh/Sigmoid activation functions.
+ *
+ * \par Model definition:
+ * \par
+ * GRU is a type of recurrent neural network (RNN). It contains two sigmoid gates and one hidden
+ * state. 
+ * \par
+ * The computation can be summarized as:
+ * <pre>z[t] = sigmoid( W_z &sdot; {h[t-1],x[t]} )
+ * r[t] = sigmoid( W_r &sdot; {h[t-1],x[t]} ) 
+ * n[t] = tanh( W_n &sdot; [r[t] &times; {h[t-1], x[t]} ) 
+ * h[t] = (1 - z[t]) &times; h[t-1] + z[t] &times; n[t] </pre>
+ * \image html GRU.gif "Gate Recurrent Unit Diagram"
+ *
+ * \par Variables Description:
+ * \par
+ * \li \c update_gate_weights, \c reset_gate_weights, \c hidden_state_weights are weights corresponding to update gate (W_z), reset gate (W_r), and hidden state (W_n).
+ * \li \c update_gate_bias, \c reset_gate_bias, \c hidden_state_bias are layer bias arrays
+ * \li \c test_input1, \c test_input2, \c test_history are the inputs and initial history
+ *
+ * \par
+ * The buffer is allocated as:
+ * \par
+ * | reset | input | history | update | hidden_state |
+ * \par
+ * In this way, the concatination is automatically done since (reset, input) and (input, history)
+ * are physically concatinated in memory.
+ * \par
+ *  The ordering of the weight matrix should be adjusted accordingly.

+ * \par Description:
+ * \par
+ * Demonstrates a convolutional neural network (CNN) example with the use of convolution,
+ * ReLU activation, pooling and fully-connected functions.
+ *
+ * \par Model definition:
+ * \par
+ * 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 \c im2col data.

+ * \li \c conv1_bias, \c conv2_bias, \c conv3_bias are convolution layer bias arrays

+ *
+ * \par Description:
+ * \par
+ * Demonstrates a gated recurrent unit (GRU) example with the use of fully-connected,
+ * Tanh/Sigmoid activation functions.
+ *
+ * \par Model definition:
+ * \par
+ * GRU is a type of recurrent neural network (RNN). It contains two sigmoid gates and one hidden
+ * state. 
+ * \par
+ * The computation can be summarized as:
+ * <pre>z[t] = sigmoid( W_z &sdot; {h[t-1],x[t]} )
+ * r[t] = sigmoid( W_r &sdot; {h[t-1],x[t]} ) 
+ * n[t] = tanh( W_n &sdot; [r[t] &times; {h[t-1], x[t]} ) 
+ * h[t] = (1 - z[t]) &times; h[t-1] + z[t] &times; n[t] </pre>
+ * \image html GRU.gif "Gate Recurrent Unit Diagram"
+ *
+ * \par Variables Description:
+ * \par
+ * \li \c update_gate_weights, \c reset_gate_weights, \c hidden_state_weights are weights corresponding to update gate (W_z), reset gate (W_r), and hidden state (W_n).
+ * \li \c update_gate_bias, \c reset_gate_bias, \c hidden_state_bias are layer bias arrays
+ * \li \c test_input1, \c test_input2, \c test_history are the inputs and initial history
+ *
+ * \par
+ * The buffer is allocated as:
+ * \par
+ * | reset | input | history | update | hidden_state |
+ * \par
+ * In this way, the concatination is automatically done since (reset, input) and (input, history)
+ * are physically concatinated in memory.
+ * \par
+ *  The ordering of the weight matrix should be adjusted accordingly.
