β MLOps: Set of practices to manage the end-to-end ML lifecycle
Detailed Explanation
MLOps, which stands for Machine Learning Operations, is a framework designed to streamline the process of managing the entire machine learning lifecycle. This involves everything from the initial data preparation to model training, deployment, maintenance, and monitoring. The primary goal of MLOps is to ensure that machine learning models are developed, deployed, and maintained in a reliable and efficient way.
Examples & Analogies
Think of MLOps like an assembly line in a car manufacturing plant. Just as each part of a car is constructed in a specific order to ensure everything fits together perfectly, MLOps provides a structured approach to constructing and maintaining machine learning models, ensuring they all work effectively together.

β Experiment tracking (e.g., Weights & Biases)
Detailed Explanation
Experiment tracking is a crucial component of MLOps. It involves keeping detailed records of all experiments conducted during the model development process. This includes the data used, parameters chosen, and results obtained. Tools like Weights & Biases help data scientists maintain this documentation, which allows for easy comparison of different model versions and an understanding of what strategies work best.
Examples & Analogies
Imagine you are experimenting with different recipes for a cake. You would want to keep track of which ingredients you used and how much, so next time you could replicate a successful cake or improve on a failed attempt. Experiment tracking in MLOps serves a similar purpose in the machine learning domain.
Model Versioning

β Model versioning
Detailed Explanation
Model versioning refers to the practice of maintaining different versions of a machine learning model as it is trained and improved over time. This is important because as improvements are made, it's essential to track changes so that previous versions can be referenced if needed. Proper versioning allows teams to pick and choose which model works best for their application, ensuring that they can roll back to a previous model if the latest version does not perform well.
Examples & Analogies
Think of model versioning like software updates on your phone. Sometimes, you may prefer to stick with the old version if the new update has bugs or does not fit your needs. With model versioning, data scientists have the flexibility to do the same with their machine learning models.
CI/CD for ML
