            # MixtureMapping

[![Documentation](https://github.com/VK/dash-express-components/workflows/Publish%20release/badge.svg)](https://vk.github.io/mixturemapping-doc)

Train Gaussian Mixture Mappings


## Provides:
  1. Layers to build tensorflow models to map Gaussian mixtures
  2. Tools to compute yield values of Gaussian mixtures in complex binning schemes

## Example
  
    import mixturemapping as mm  
    import tensorflow as tf

    inMeans = tf.keras.Input(shape=(mixN, inputMixM), name="Means", dtype=dataType)
    inStdDevs = tf.keras.Input(shape=(mixN, inputMixM), name="StdDevs", dtype=dataType)
    inWeight = tf.keras.Input(shape=(mixN), name="Weights", dtype=dataType)

    mapModel = tf.keras.Sequential()
    mapModel.add( tf.keras.layers.Dense(40, activation="relu", kernel_regularizer=regularizers.l2(0.001)) )
    mapModel.add( tf.keras.layers.Dense(40, activation="relu", kernel_regularizer=regularizers.l2(0.001)) )
    mapModel.add( tf.keras.layers.Dense(outputMixM))
    y = mapModel(inMeans)

    deltaModel = tf.keras.Sequential()
    deltaModel.add( tf.keras.layers.Dense(40, activation="relu", kernel_regularizer=regularizers.l2(0.001)) )
    deltaModel.add( tf.keras.layers.Dense(40, activation="relu", kernel_regularizer=regularizers.l2(0.001)) )
    deltaModel.add( tf.keras.layers.Dense(outputMixM))
    yDelta = deltaModel(inMeans)

    covALayer = mm.layers.TrainableCovMatrix(outputMixM, name="CovA")
    covA = covALayer(inMeans)

    mapLayer = mm.layers.GeneralMapping(outputMixM, name="Mapping", dtype=dataType)
    newDist = mapLayer({'means': inMeans, 'y':y, 'yDelta':yDelta, 'stdDevs': inStdDevs, 'weights': inWeight, 'covA': covA})

    distLayer = mm.layers.Distribution(dtype=dataType, regularize_cov_epsilon=0.95)
    dist = distLayer(newDist)

### Developement
```
$ py -m venv env
$ .\env\Scripts\activate
$ pip install -r requirements.txt
```
