Machine Learning Project Steps

A typical machine learning and data analytics project follows six steps: setting the research goal, data retrieval, data preparation, data exploration, data visualization, and data modeling.

Data Retrieval Step

The step in a machine learning project where suitable data sources are found, data is accessed, and raw data is collected.

Data Preparation Stage

The process of transforming raw data, identifying and correcting errors, combining data from different sources, and preparing it for modeling and visualization.

Data Exploration Goal

The goal of this step is to gain a deep understanding of the characteristics of the data for informed decisions in later steps.
