## Self-Organizing Recurrent Neural Networks 

SORN is a class of neuro-inspired computing model build based on plasticity mechanisms in biological brain and mimic neocortical circuits ability of learning and adaptation through five fundamental neuroplasticity mechanisms.


Example use cases and the API(under developement) are maintained at https://github.com/Saran-nns/PySORN_0.1

#### To install the latest release:

```python
pip install sorn
```

The library is still in alpha, so you may also want to install the latest version from the development branch:

```python
pip install git+https://github.com/Saran-nns/sorn
```

#### Dependencies
SORN supports Python 3.5+ ONLY. For older Python versions please use the official Python client


#### Usage:

##### Update Network configurations

Navigate to home/conda/envs/ENVNAME/Lib/site-packages/sorn

or if you are unsure about the directory of sorn

Run

```python
import sorn

sorn.__file__
```
to find the location of the sorn package

Then, update/edit the configuration.ini


###### Plasticity Phase

```Python
# Import 
from sorn.sorn import RunSorn

# Sample input 
inputs = [0.]

# To simulate the network; 
matrices_dict, Exc_activity, Inh_activity, Rec_activity, num_active_connections = RunSorn(phase='Plasticity', matrices=None,
                                                                          time_steps=100).run_sorn(inputs)

# To resume the simulation, load the matrices_dict from previous simulation;
matrices_dict, Exc_activity, Inh_activity, Rec_activity, num_active_connections = RunSorn(phase='Plasticity', matrices=matrices_dict,
                                                                          time_steps=100).run_sorn(inputs)
```

##### Training phase:

```Python
matrices_dict, Exc_activity, Inh_activity, Rec_activity, num_active_connections = RunSorn(phase='Training', matrices=matrices_dict,
                                                                          time_steps=100).run_sorn(inputs)
```

#### Network Output Descriptions:
    matrices_dict  - Dictionary of connection weights ('Wee','Wei','Wie') , Excitatory network activity ('X'), Inhibitory network activities('Y'), Threshold values ('Te','Ti')

    Exc_activity - Collection of Excitatory network activity of entire simulation period

    Inh_activitsy - Collection of Inhibitory network activity of entire simulation period

    Rec_activity - Collection of Recurrent network activity of entire simulation period

    num_active_connections - List of number of active connections in the Excitatory pool at each time step
