somlib 0.0.4

# SOM
This is python implementation for Kohonen Self Organizing map using numpy and tensor

## Installtion

**Python 3**
`pip install somlib`

## Usage

1. Numpy implementation

```
from somlib import som
s = som.SOM(neurons=(5,5), dimentions=3, n_iter=500, learning_rate=0.1)
s.train(samples) # samples is a n x 3 matrix
print("Cluster centres:", s.weights_)
print("labels:", s.labels_)
result = s.predict(samples)
```

Here 5,5 is the dimention of neurons, 3 is the number of features. samples is numpy array with each sample a 3 dimentional vector

2. Tensor implementation

```
from somlib import som
s = SOM(neurons=(5,5), dimentions=3, n_iter=500, learning_rate=0.1, mode="tensor")
s.train(samples) # samples is a n x 3 matrix
print("Cluster centres:", s.weights_)
print("labels:", s.labels_)
result = s.predict(samples)
```

### Display clusters
To display clusters after training use this

```s.displayClusters(samples)```
