# Agenda

- Create Data Operation
- Create Data Product
- Create Transformation Script
- Create Data Transformation
- See Data Analysis
- See Data Array
- Plot Data

This tutorial shows an example of Machine Learning with Wendelin.

Based on data from previous tutorials we will predict air pressure from humidity using Linear Regression by scikit-learn and visualize results.

Before doing this tutorial make sure you read and completed the following tutorials

- HowTo Transform Data
- HowTo Resample Data
- HowTo Create Notebook with Graphs

# Data Operation

Open your Wendelin dashboard.

In Modules click on Data Operations Module

# Add Data Operation

Click on Add to add a new Data Operation.

# Add Data Operation

Click Proceed to continue.

# Fill the Form

Fill the form to create Data Operation.

Title - we name it Predict Pressure

Reference - data-operation-predict-pressure

Script ID - DataAnalysisLine_predictPressureFromHumidity: this script will do all the magic. It doesn't exist yet, we will create it later in this tutorial.

At the don't forget to Save the changes.

# Validate

Click on Validate on left side panel to validate Data Operation.

# Confirm Validation

Click Validate to confirm validation.

# Data Product

Now we need to create a new Data Product which will the output Data Product of the Transformation.

# Create Data Product

Create a new Data Product as described in HowTo Create Data Product tutorial with following values

Title - Predicted Data Array

Quantity Unit - Unit/Piece

Reference - environment-predicted-array

Item Types

- Data Array

Use

- Big Data/Ingestion/Stream Ingestion

# Portal Callables

After Data Product is created and validated, navigate to page called Portal Callables by adding /#/portal_callables at the end of the URL of your wendelin instance.

There we will create and store a the prediction script.

#

# Add Transformation Script

Click on Add button to add a new script.

# Add Transformation Script Cont.

Choose Python Script as Document Type and click on Create Document to create an empty python script.

# Fill The Form

Define ID, Title and Reference of your script.

We name it DataAnalysisLine_predictPressureFromHumidity as we did in Data Operation at the beginning of this tutorial.

Next we define the parameters we will give to our script.

in_array - the input dictionary that contains Data Array where raw data is stored after the previous transformation.

out_array - the output Data Array where results of the prediction will be stored.

At the end click Save to save the changes.

# Transformation Script

The script we write in the textbox area at the bottom of the page.

# Transformation Script Cont.

    import numpy as np
    import pandas as pd
    from sklearn.model_selection import train_test_split
    from sklearn.linear_model import LinearRegression

    def predict(zbigarray):

      humidity = zbigarray[:]["humidity_mean"]
      pressure = zbigarray[:]["pressure_mean"]

      humidity = humidity[humidity !=0 ]
      pressure = pressure[pressure !=0 ]

      humid_train, humid_test, pressure_train, pressure_test = train_test_split(humidity.reshape(-1,1), pressure.reshape(-1,1), test_size=0.2, random_state=0)

      regressor = LinearRegression()
      regressor.fit(humid_train, pressure_train) #training the algorithm

      pressure_pred = regressor.predict( zbigarray[:]["humidity_mean"].reshape(-1,1))

      df = pd.DataFrame({'Date': zbigarray[:]["date"],'Actual':zbigarray[:]["pressure_mean"], 'Predicted': pressure_pred.flatten()})

      return  df

    out_data_array = out_array["Data Array"]

    in_data_array = in_array["Data Array"]

    in_zbigarray = in_data_array.getArray()
    if in_zbigarray is None:
      return

    if in_zbigarray.shape[0] == 0:
      return

    df = predict(in_zbigarray)

    ndarray = df.to_records(convert_datetime64=False)
    dtype = [('Date', '<M8[ns]'),('Actual', '<f8'), ('Predicted', '<f8')]

    zbigarray = out_data_array.getArray()
    if zbigarray is None:
      zbigarray = out_data_array.initArray(shape=(0,), dtype=dtype)
      zbigarray.append(ndarray)
    else:
      start_index = len(zbigarray)
      array_len =  len(ndarray)
      if start_index < array_len:
        zbigarray.append(ndarray[start_index:])

This script takes as an input data from resampled Data Array, splits data into training and tests set.

Then it learns on training set and predicts air pressure based on humidity.

In output array it stored the true and predicted values.

Don't forget to save the changes after editing the script.

# Data Transformation

Head back to Data Transformation.

Now you can see that we have 3 Data Transformation Lines.

The first line defines what operation will be done.

The second line defines on what the operation will be done - the input.

The last line defines the output.

The very last step is to validate the Data Transformation.

Click on Validate on the left side panel to validate the Data Transformation.

# Data Array Module

Go to Data Array Module to see the data.

# Data Array

Here we can see the newly created Data Arrays with prediction results - Predict Pressure.

Click on it to navigate to the array.

# Data Array

Click on Preview to see the data.

Note it might take few minutes (<10) until data appears.

# Data Array

Data is here!

Copy/paste the code to your notebook and save the changes.

Note: you will need to provide the URL of your instance in the script.

For that change the line :

    hateoas_url = "https://softinstXXX.host.vifib.net/erp5/web_site_module/default_wendelin_front/hateoas/";

The script will find automatically the Data Array with prediction results based on the Data Product and plot the data using plotly library.

# Notebook

After writing the script and saving the changes click on the Editable checkbox to (uncheck it) on the left side panel to see the result.

# Data Visualisation

If everything was done correctly you will see the plot of your data.
