What is batch size?
The number of data samples used to train a model at one time
batch size explained in plain English
In machine learning, a batch size refers to the number of data samples that are used to train a model at one time. This is an important parameter that can affect the performance and efficiency of the training process.
Analogy
Think of batch size like the number of students in a classroom. Just as a teacher can only effectively teach a certain number of students at a time, a model can only process a certain number of data samples at once.
Example
For example, if you're training a model to recognize images of dogs and cats, you might use a batch size of 32, which means the model will process 32 images at a time.
How is batch size used?
Common misconceptions about batch size
A common misconception is that a larger batch size is always better, but this can actually lead to slower training times and decreased model performance.
History
The concept of batch size has been around since the early days of machine learning, but it has become increasingly important with the rise of deep learning models that require large amounts of data to train.
