What is MLOPS ? and Why Should You Start Using It in Your Machine Learning Projects? …

What is MLOPS?

MLOPS refers to the combined use of Machine Learning and DevOps to create robust automation, tracking, pipeline, monitoring, and packaging system for machine learning models during its Life Cycle.

So, let start with Machine learning first, what is it exactly? Machine Learning is defined as a data analysis technique that automates the creation of analytical models. It is a subfield of Artificial Intelligence (aka AI) that is predicated on the premise that systems can learn from data, spot patterns, and make choices with little or no human interaction e.g. book recommendations on Amazon, music recommendations on Spotify, and self-driving cars.

Next, what is DevOps? DevOps is a collection of cultural ideas, practices, and technologies software development (Dev) with information technology and operations (Ops). Its main goal is to reduce the systems development life cycle and enable the continuous delivery of high-quality software at a quicker rate than traditional software development and infrastructure management methods.

Now let's see what is the machine learning life cycle

What is Machine Learning Life Cycle?

The machine learning life cycle may be described as a multi-component flow, in which each component affects the next ones. The first component (1)Prepare the dataset, this step includes the data collection phase, transforming and cleaning the raw data. In the second component of the machine learning life cycle (2) Experiments are conducted, the dataset is explored and features are extracted from it for further investigation. After in the (3)Train component, a model is selected and the training process is started to fine-tune its parameters, during this process the model is monitored and evaluated at the end. Once a model satisfies the requirements set (e.g. precision/accuracy) is selected, in the last component (4)Deploy the chosen model is deployed for inference and monitored.


What Are The Available Free MLOPS Tools?

At the time of writing this post (end of 2021), there were a lot of companies offering MLOPS tools. The tools have all the same goal which is to allow the users to track their Machine Learning during its Lifecycle, with some differences between them like for example:

  • Open Source (Cost / Support / UI / …)
  • Platform and Language Support (Python / API Support / … )
  • Data Storage (Local / Cloud / Hybrid)
  • Custom Visualization (Accurate / Clear / …)
  • Ease of Setup and Use (Requirements / UI & UX)
  • Scalability for a large number of experiments (Team / Experiment Volume)
  • Datasets Tracking (Delta Data1 vs Data2 /…)
  • Distributed execution of experiments (Scheduler / Containers / K8s / HPC)

In this section, some of the open-source MLOps tools are listed. The focus is set only on the free ones as they give you the freedom to enjoy the automation and flexibility offered by MLOps without spending a dollar.

1. ClearML

ClearML is an end-to-end platform that connects all data science tools in a unified environment. It is a suite of open source tools for automating the preparation, execution, and analysis of machine learning experiences. The tool helps keep track of settings, jobs, artifacts, metrics, debug data, metadata and log everything into one interface

The execution of the ClearML stack can be self-hosted. The platform’s official website offers a free hosting plan and a paid hosting plan.

More about the tool https://clear.ml/docs/latest/docs/

PS: This is the one I am currently using in my projects

2. Weight and Biases

It is a tool that allows you to easily track and record the performance of deep learning models. The tool makes it possible to follow experiences, improve models and share the results with collaborators while monitoring results. Hyperparameters and output measurements are stored in one place. The logs of each experiment are saved, in order to consult the progress made and compare the models with existing projects.

Visualization tools are also available to understand the immense amount of data in a clear manner. Similar to ClearML to use Weights & Biases, just add a few lines of code to your script.
