Azure Machine Learning Model In Production

Machine Learning is the process of training a machine with specific data to make inferences. We can deploy Machine Learning models on the cloud (like Azure) and integrate ML models with various cloud resources for a better product.

In this blog post, we will cover How to deploy the Azure Machine Learning model in Production.

Overview Of Azure Machine Learning

Machine Learning is a subset of Artificial Intelligence. We can deploy the Machine Learning model on Azure by various means like using Azure ML Studio, Azure ML SDK (Python, R), Automated ML, and Visual Studio.

There are four types of Machine Learning Models:

1) Supervised Machine Learning: In this, we provide the machine with the labeled data for training based on which the machine will create a function to make predictions on some test data.

• Regression Model: These models predict continuous data based on training.
• Classification Model: These models classify the input test data (Like yes/no, true/false, bike/car/bus, etc).

2) Unsupervised Machine Learning: In this model, we provide unlabeled data for training, and based on the training the model will predict some patterns in the data.

• Clustering: These models segregate data into different groups to form a cluster. (like age >18 & age<18)
• Association: These models used to combine some data based on the learning of the model. (eg. fruit basket analysis)

3) Semi-Supervised Machine Learning: These models are the combination of both Supervised & Unsupervised machine learning as the dataset contains both labeled and unlabeled data.

4) Reinforcement Learning: In the Reinforcement learning algorithm (called the agent), the algorithm continuously learns from the environment in an iterative fashion.

Benefits Of Using Azure Machine Learning

1. No Data Limit to import data from various Azure Data Storage services.
2. User Friendly and embedded with less restrictive tools.
3. In Azure ML, we can publish the ML model as a web service.
4. Drag and Drop console (pipeline) for no-code model generation and deployment.
5. Data Security & Monitoring over Azure ML Services.

Steps To Create A Training Pipeline Using Azure ML Designer

Note: Before creating a pipeline you must have created a Workspace & Compute Cluster on which the model is deployed.

Check how to create an Azure Machine Learning Workspace.

Check what are Compute targets in Azure ML

Note: Before creating a pipeline you must import a dataset into your workspace on which the model is trained. We are using Diabetes Dataset in this example

Note: The link from where you can import data into the workspace. Click here

1) On the left side of the designer, select the Datasets (⌕) tab, expand the Datasets section, and drag the diabetes dataset on the canvas.

Note: You can search for the modules that you want to bring on the canvas.

2) Connect the output from the diabetes dataset module to the input of the Normalize Data module.

Normalization is the process of scaling the data of each column between a smaller range so that all values of all the columns are between the same range.

Note: You need to specify which columns (features) you need to normalize by clicking on the normalize data module.

Note: Do Check Our Blog Post  On MLOps For An Overview.

3) Import Split Dataset Module, then connect the (left) output of the Normalize Data module to the input of the Split Data module.

Note: In this module, you need to specify the percentage of data taken for training purpose & testing purposes (for evaluation).

4) Search for the Train Model Module and drag a Train Model module to the canvas, under the Split Data module. Connect the left output of the Split Data module to the right input of the Train Model module.

Note: In this module, you need to specify the label (column) name whose value you want to predict.

5) Search for the Two-Class Logistic Regression module and drag it to the canvas, to the left of the Split Data module, and above the Train Model module. Then connect its output to the left input of the Train Model module.

6) Search and drag a Score Model module to the canvas, below the Train Model and connect the output of the Train Model module to the left input of the Score Model module & right output of the Split Data module to the right input of the score model module.

7) Search & drag an Evaluate Model module to the canvas, under the Score Model and connect the output of the Score Model module to the left input of the Evaluate Model.

8) Verify that your pipeline looks similar to the following:

9) At the top right, click Submit. It will take some time to submit the model. After the processing completed it will look like the following image.

Steps To Deploy A ML Model Using Azure ML Designer

In Azure Machine Learning we can deploy the trained model on Inference Cluster which will generate an endpoint that can be used by clients to use these models and make inferences on some new data.

Note: Before deploying the Inference Pipeline make sure you have created an Inference Cluster on which we will deploy the inference pipeline.

1) In the Create inference pipeline drop-down list, click a Real-time inference pipeline.

2) Rename the new pipeline to Predict Diabetes, Delete the diabetes dataset from the inference pipeline, and replace it with an Enter Data Manually module.

PatientID, Pregnancies, PlasmaGlucose, Diastolic BloodPressure, TricepsThickness, SerumInsulin, BMI, DiabetesPedigree, Age

1662484,6,73,61,35,24,18.74367404,1.074147566,75

3) The inference pipeline includes the Evaluate Model module, which is not useful when predicting from new data, so delete this module.

4) To limit the output to only the prediction and probability, delete the connction between the Score Model module and the Web Service Output, add an Execute Python Script module.

Note: Modify the settings of the Execute Python Script module to use the following code (replacing all existing code):

import pandas as pd 

def azureml_main(dataframe1 = None, dataframe2 = None):

    scored_results = dataframe1[[‘PatientID’, ‘Scored Labels’, ‘Scored Probabilities’]]

    scored_results.rename(columns={‘Scored Labels’:’DiabetesPrediction’,

                                   ‘Scored Probabilities’:’Probability’},

                          inplace=True)

    return scored_results

5) Verify that your pipeline looks similar to the following:

6) After some time we can see the inference pipeline is submited successfully.

7) At the top right, click Deploy, and set up a new real-time endpoint named predict-diabetes on the inference cluster (ML-inference) you created.

8) When the predict-diabetes endpoint opens, on the Consume tab, note the REST endpoint and Primary key.

Note: This endpoint we can share with clients which can be used to make inferences on some test data using the trained model.
