Machine Learning - Life Cycle



The machine learning life cycle is a process that involves several stages from problem identification to model deployment. Here are the six stages of the machine learning life cycle −

Problem Definition

The first step in the machine learning life cycle is to identify the problem you want to solve. This stage involves understanding the business problem, defining the problem statement, and identifying the success criteria for the machine learning model.

Data Collection

The second stage is to collect the data that will be used to train the machine learning model. This stage involves identifying the relevant data sources, collecting and storing the data, and cleaning and preprocessing the data to prepare it for analysis.

Data Preparation

In this stage, the data is prepared for analysis by performing data exploration, feature engineering, and feature selection. Data exploration involves visualizing and understanding the data, while feature engineering involves creating new features from the existing data. Feature selection involves selecting the most relevant features that will be used to train the machine learning model.

Model Building

In this stage, the machine learning model is built using the prepared data. The model building process involves selecting the appropriate machine learning algorithm, tuning the hyperparameters of the algorithm, and evaluating the performance of the model using cross-validation techniques.

Model Evaluation

In this stage, the performance of the machine learning model is evaluated using a set of evaluation metrics. These metrics measure the accuracy, precision, recall, and F1 score of the model. If the model's performance is not satisfactory, it may be necessary to return to the model building stage to improve the model's performance.

Model Deployment

The final stage of the machine learning life cycle is to deploy the machine learning model into production. This involves integrating the model into the production environment, testing the model in a real-world scenario, and monitoring the model's performance to ensure that it continues to perform as expected.

The machine learning life cycle is an iterative process, and it may be necessary to revisit previous stages to improve the model's performance or address new requirements. By following the machine learning life cycle, data scientists can ensure that their machine learning models are effective, accurate, and meet the business requirements.
