# Random neural networks

A library for sampling random neural networks.

### The model

```math

\tau \frac{dh_i}{dt}=-h_i+\sum_{j=1}^N J_{ij}\phi(h_j),

```

where:

- $`h_i(t)`$ is the state of neuron $i$ at time $t$.

- $`J_{ij}`$ is the weight of the connection from neuron $j$ to neuron $i$.

  - It is sampled from $\mathcal{N}(0, g^2/N)$, where $g$ is our coupling strength.

  - $`J_{ii}=0`$

- $`\phi`$ is the activation function ($`=\tanh`$)
