Description: Batch size refers to the number of data samples processed together in a batch during training or inference. In the context of machine learning and neural networks, batch size is a crucial parameter that affects the performance and efficiency of the model. A small batch size allows the model to update more frequently, which can lead to faster convergence, but may also result in higher variance in weight updates. Conversely, a large batch size provides more stable gradient estimates but may require more memory and processing time, and can lead to slower convergence. Choosing the right batch size is essential for optimizing the training process, as it influences learning speed, model generalization, and resource utilization. In various data processing environments and distributed systems, batch size can also impact processing efficiency and operation latency. Therefore, it is an aspect that must be carefully considered during data preprocessing and hyperparameter optimization phases.
