Streamlining ML Projects with MLOPs and Azure ML

Why do we need to streamline the Machine Learning Projects?

During a machine learning project, the phases to be implemented are defined by machine learning workflows. Data collection, preprocessing, dataset building, training and evaluation, and production deployment are the typical phases in a Machine learning project. Users cannot automate all the features, but some aspects of the machine learning workflow, like model and feature selection, can be automated.

Generally, these steps are accepted as a standard. Firstly define the project and find an approach while creating a machine learning project. Build a workflow that allows you to scale up to a production-grade solution and not try to fit the model in the rigid workflow.

What is the workflow of Machine Learning?

The workflow of machine learning defines the steps of a particular mL implementation. The workflow of machine learning can be varied by project except for the following phases.

Data Gathering

The main stage of the workflow is data gathering. While collecting data, define the potential usefulness and accuracy of the project with the quality of the collected data. To collect data, users need to identify sources and aggregate data from those sources into a single dataset.

Pre-processing of Data

The user needs to pre-process the data after collecting it. It involves cleaning, verifying, and formatting the data.

Split Datasets

This phase includes the process of dividing data into three parts.

Training set - Is used to process the information and train the algorithm.
Validation set - Is used to estimate the model's accuracy and finetune the model parameters.
Test set - Is used to assess the accuracy and performance of the models.

Training and Refinement

Once users have datasets, users are ready to train their model. This involves feeding a training set to an algorithm to learn appropriate parameters and features used in classification. Once training is complete, then refine the model using the validation dataset. This may involve modifying or discarding variables and includes a process of tweaking model-specific settings (hyperparameters) until an acceptable accuracy level is reached.

Machine Learning Evaluation

Finally, test your model after a good set of hyperparameters is found and model accuracy is optimized. Testing uses a test dataset to verify that models are using accurate features. Based on the received feedback, train the model to improve accuracy, adjust output settings, or deploy the model as needed.

Streamline ML Projects

It is an engineering discipline that aims to bring together the creation (dev) and deployment (ops) of machine learning systems to standardize and expedite the continuous delivery of high-performing models in production.

Users have a new Machine learning engineering culture to help simplify the overall system. Everyone from upper management with no technical expertise through Data Scientists, DevOps, and ML Engineers was involved in the system.

How to streamline Machine Learning Projects with MLOPs?

The importance of MLOPs cannot be overstated. By establishing more efficient processes, utilizing data analytics for decision-making, and enhancing customer experience, machine learning helps individuals and organizations deploy solutions that uncover previously untapped streams of revenue, save time, and cut costs.

These objectives are challenging to achieve without a stable foundation to operate. MLOPs automates model creation and deployment, resulting in shorter time-to-market and fewer operational expenses. It assists managers and developers in making more strategic and agile decisions. MLOPs provides a road map for individuals, small teams, and even enterprises to achieve their objectives despite restrictions, such as sensitive data, limited resources, and tight budgets.

Following are the essential skills that are needed to focus on:

Framing ML problems from business objectives

Machine learning systems usually begin with a commercial purpose or objective. It might be as easy as lowering the proportion of fraudulent transactions to less than 0.5 percent or developing a technique to identify skin cancer in dermatologist-labeled photographs.

These goals frequently include performance metrics, technical requirements, a project budget, and KPIs (Key Performance Indicators) that guide the monitoring of deployed models.

Architect ML and data solutions for the problem

After that, the goals are converted into ML problems. The next stage is to begin looking for relevant input data and the types of models to test with that data.

One of the most difficult challenges is finding data. It's a multi-step procedure that includes the following steps:
Examine the data's trustworthiness as well as its source.
What is the best way to make the dataset accessible?
Is the data coming from a source of static (files) or real-time streaming (sensors)?
What is the number of sources that will be used?
How do you create a data pipeline that can drive training and optimization once the model is in production?
What are the many types of cloud services that may be used?

Data Preparation and Processing

Feature engineering, cleaning (formatting, testing for outliers, imputations, rebalancing, and so on), and finally selecting the set of features that contribute to the output of the underlying issue are all part of data preparation. A comprehensive pipeline is built and coded to provide clean and compatible data to be fed into the next model building step.

Choosing the proper combination of cloud services and architecture that is both performant and cost-effective is a crucial component of building such pipelines.

Model Training and Experimentation — Data Science

Move on to the next phase of training ML models as soon as the data is ready. The initial part of training is now iterative, using various models and narrowing down to the optimal answer using a combination of quantitative measurements such as accuracy, precision, recall, and qualitative model analysis that accounts for the mathematics that drives the model or, put, the model's explainability.

Building and Automating ML Pipelines

While building ML pipelines following tasks should be kept in mind:

Determine the system's requirements, including parameters, compute requirements, and triggers.
Create pipelines for training and testing.
The pipeline should be tracked and audited.
Validate the information.

Production System Model Deployment

The main two ways to deploy models:

First is a static deployment where a model is saved into the application and then deployed.
The second is dynamic deployment which uses a framework like a flask and offers an endpoint that responds to users' requests.

Different methods can be used with dynamic deployment:

Deployment on server
Deployment in a container
Serverless deployment
Model streaming - all models registered on stream processing engines like Apache spark instead of API.

Monitor, Optimize, and Maintain Models

An organization must monitor the success of the models in production while also ensuring excellent and equitable governance. The term "governance" refers to control mechanisms to guarantee that the models fulfill their obligations to all stakeholders, workers, and users.

We require data scientists and DevOps engineers to manage the entire system in production throughout this period by executing the following tasks:

Keeping monitoring of model forecasts' performance deterioration and business quality.
Creating recording techniques and setting metrics for continual assessment.
Identifying and correcting system flaws, as well as the introduction of biases.
Tuning the model's performance in both training and serving pipelines that have been implemented in production.
