Difference between deep neural networks and expectation maximization algorithm
Having had a short encounter with deep neural networks, it seems to boil down to the task of determining the values of a vast amount of parameters.
The expectation maximization algorithm, of which I ...

Approximation of continuous function by multilayer Relu neural network
For continuous/holder function $f$ defined on a compact set K, a fix $L$ and $m_1,m_2,\dots,m_L$, can we find a multilayer Relu fully connected network g with depth $L$ and each $i$-th layer has width ...

Neural networks over gadgets other than $\mathbb{R}$
Recently, I learned that neural networks (NN) can be defined over fields other than $\mathbb{R}$: for example, Khrennikov and Tirozzi wrote a paper in 1999 (!) on $p$-adic neural networks, or neural ...

How sensitive are Neural Networks to weight change?
Let's consider the space of feedforward neural networks with a given structure: $L$ layers, $m$ neurons per layer, ReLu activation, input dimension $d$, output dimension $k$.
Which means I'm ...

Structures of the space of neural networks
A neural network can be considered as a function
$$\mathbf{R}^m\to\mathbf{R}^n\quad
\text{by}\quad x\mapsto w_N\sigma(h_{N-1}+w_{N-1}\sigma(\dotso h_2+w_2\sigma(h_1+w_1 x)\dotso)),$$
where the $w_i$ ...
