# Model Performance Investigator


## Short Description

        Model Performance Investigator is used to analyse the performance of Machine Learning and
    Deep learning models. It gives the user, basic idea how the model performance on given data.
    So that user can start work on the right model.
        Current Version supports Regression and Classification type of problems with 
    Visualization support.


## Installation

    pip install model-performance-investigator


## How to use ?

    * Import the package.
        from model_analyzer.ml_models import MLPredictor as ml

    * Call the required function, assign it to a variable and run.


## Functions ?

    1. predector()  ->  Used to get Score for the Models. Returns score data
                        if error is not present else returns error message.

    2. draw_plot()  ->  Used to plot Distribution plot of the Features. Return 
                        PDF file if correct dataframe send with only 'int' 
                        featurs only else returns error message.

                                then this package use default tunning parameters.

        * set_plot -> Creates Residual Plot for regression model only.
                      By default, it is Set as True.

                       integers only.

        * columns -> It is optional parameter. By default all the columns are selected.
                     User can send required features alone.

                     TYPE : List

                     FORMAT :
                         columns = ['ColA', 'ColB', 'ColC']

        * plot_type -> It is optional parameter. By default 'Histograme' plot is selected.
                       User can select Histograme or Scatter plots

                       TYPE : String

                       Keys :
                           Histograme -> hist

        output = ml.draw_plot('regression', dataframe, columns =  ['ColA', 'ColB', 'ColC'],
                 plot_type='hist')
