Implement tensor operation with mini batches instead of Matrix multiplication in forward pass

The forward pass in neural network can be written as g(Wx+b). W is the weights Matrix, x is the input vector and b is bias, and g the non linearity, the activation function. However x can have more ...

Why do language models produce different outputs for same prompt?

For conventional 'Neural Networks', the weights simply act as a transformation in highly multi-dimensional space; for a forward pass, the output is always the same since there is no stochastic ...

Is there any existing mechanism that allows us to pass input from randomly selected layers of neural network per iteration?

Consider the following neural network with $\ell$ layers. $$i_0 \rightarrow h_1 \rightarrow h_2 \rightarrow h_3 \cdots \rightarrow h_{\ell-1} \rightarrow o_{\ell} ,$$ where $i, h, o$ stands for ...

What is the difference between the forward pass of the Multi-Layer Perceptron, Deep AutoEncoder and Deep Belief Network?

Multi-Layer Perceptron (MLP), Deep AutoEncoder (DAE), and Deep Belief Network (DBN) are trained differently. However, do they follow the same process during the inference phase, i.e., do they ...

How can I perform the forward pass in a neural network evolved with NEAT, given that some connections may not exist or there may be loopy connections?

I have a problem that arose as part of a NEAT (Neuro Evolution Through Augmenting Topologies) implementation that I am writing. I am wanting it to produce topologies or graphs that describe neural ...

What is the Preferred Mathematical Representation for a Forward Pass in a Neural Network?

I know this may be a question of semantics but I always see different articles explain forward pass slightly different. e.g. Sometimes they represent a forward pass to a hidden layer in a standard ...

What is the computational complexity of the forward pass of a convolutional neural network?

How do I determine the computational complexity (big-O notation) of the forward pass of a convolutional neural network? Let's assume for simplicity that we use zero-padding such that the input size ...

Could a quantum computer perform vectorized forward propagation in deep networks?

Forward propagation in Deep Neural Networks In the "Forward Propagation in a Deep Network" video on Coursera, Andrew NG mentions that there's no way to avoid a for loop to loop through the ...

What is the time complexity of the forward pass and back-propagation of the sequence-to-sequence model with and without attention?

I keep looking through the literature, but can't seem to find any information regarding the time complexity of the forward pass and back-propagation of the sequence-to-sequence RNN encoder-decoder ...

Are my computations of the forward and backward pass of a neural network with one input, hidden and output neurons correct?

I have computed the forward and backward passes of the following simple neural network, with one input, hidden, and output neurons. Here are my computations of the forward pass. \begin{align} net_1 &...

How to compute the output of a neural network produced by NEAT?

I used to work with layered neural networks, where, given certain inputs, the output is produced layer-by-layer. With NEAT, a neural network may assume any topology, and they are no longer layered. So,...
