Over or under fitting is due to the sparseness of data. Implementing sparse connections in neural network (Theano) An alternative would be to do matrix multiplication, where many weights are set to 0 (= no connection), but that would be very inefficient compared to SparseBlockGemv as each neuron is only connected to 2-6 neurons in the previous layer out of ~100000 neurons. For a sparse parameter vector, gs i would consist of mostly zeros. , it uses . The deep neural network is of good stability against disturbance for fault diagnosis.

The concept of sparseness refers to the network"s connectivity structure, such that each neuron receives inputs from only a limited number of other neurons, and to the network"s state which describes the level of activity of the entire neural population, so that only few neurons are active at any one time. Suppose the total number of layers is L. A di-verse set of experiments empirically validates the usage of general forms of ﬁlters. It applies backpropagation , by setting the target value same as input. We’re releasing highly-optimized GPU kernels for an underexplored class of neural network architectures: networks with block-sparse weights. 1 Neural network formulation A neural network is put together by hooking together many of our simple “neurons,” so that the output of a neuron can be the input of another. This transform is deﬁned in the context of a one-pass feed-forward spiking neural network, and the output is the list of its neurons’ spikes: it is recursively constructed using a greedy matching pursuit scheme which ﬁrst selects higher contrast energy values.
