Method

All the architectures were built using Keras. The loss is categorical cross entropy, adam optimizer and learning rate of 0.001 was used

model.add(Dense(128, activation='relu', input_dim=input_shape))
    model.add(Dropout(0.5))
    model.add(Dense(256, activation='relu'))
    model.add(Dense(256, activation='relu'))
    model.add(Dropout(0.5))
    model.add(Dense(128, activation='relu'))
    model.add(Dropout(0.5))
    model.add(Dense(64, activation='relu'))
    model.add(Dropout(0.5))
    model.add(Dense(output_shape, activation='softmax'))
model = Sequential()
    model.add(Dense(25, 
    kernel_initializer=keras.initializers.glorot_normal(seed=0), kernel_regularizer=keras.regularizers.l2(1e-4)))
    model.add(Activation('relu'))
    model.add(Dense(10, kernel_initializer=keras.initializers.glorot_normal(seed=0))), kernel_regularizer=keras.regularizers.l2(1e-4)))
    model.add(BatchNormalization())
    model.add(Activation('relu'))
    model.add(Dropout(0.3))
    model.add(Dense(num_classes, kernel_initializer=keras.initializers.glorot_normal(seed=0), activation='softmax'))

Remark: Although, the method in [@macem] does not really perform the constrained optimization but uses regularization like 'Elasticnet' penalty to impose sparsity, we will assume that our PPs and PNs are the result of these optimizations just for simplicity of exposition. The only difference is that the sparsity $k$ cannot be pre-determined but is typically a constant for many training samples in practice.
