Batch Normalization
Batch Normalization is a technique used to make artificial intelligence systems learn better and faster. Think of it like a teacher who helps standardize test scores in a class so they're easier to compare and understand. In machine learning jobs, when candidates mention Batch Normalization, they're talking about their experience with making AI models more reliable and efficient. This is similar to other techniques like Layer Normalization or Instance Normalization. When you see this term in a resume, it usually indicates that the candidate has worked on improving how well AI systems learn and perform their tasks.
