Understanding a Machine Learning Training Dataset: 72,000 Images Across 9 Equal Categories When building effective machine learning models, one crucial component is the quality and structure of the training dataset. A well-balanced dataset ensures the model learns evenly across all categories, improving accuracy and generalization. Consider a practical example: a machine learning training dataset containing 72,000 images carefully divided equally into 9 distinct categories. But how many images are in each category—and why does this balance matter? ### How Many Images Are in Each Category? With 72,000 images split equally across 9 categories, the calculation is straightforward:
