Welcome Tech Geeks! Introduction In machine learning, raw data is often messy, incomplete, and unorganized. Before you feed this data to a machine learning model, you need to prepare it. This process is called data preprocessing . It ensures the data is clean, consistent, and ready to be understood by the model. Think of it like preparing ingredients before cooking. If your vegetables aren't cleaned or cut properly, you can't cook a great meal. Similarly, without preprocessing, machine learning models won't deliver accurate predictions. In this blog, we will explore the key data preprocessing techniques every ML beginner must know. By the end, you'll have a solid understanding of how to clean, transform, and prepare data to boost the performance of machine learning models. What is Data Preprocessing? Data preprocessing is the process of converting raw data into a clean, structured, and usable format. It removes errors, fills in missing information, and prepares the data...
