Module 14 - Unit 04 TensorFlow Data Pipelines
In this video, we explore how to build efficient and scalable data pipelines using TensorFlow's tf.data API. Data pipelines play a critical role in machine learning because even the most powerful models can be slowed down by inefficient data loading and preprocessing.
You will learn how to create datasets from NumPy arrays and files, apply transformations such as map(), shuffle(), and batch(), improve performance with prefetch(), integrate data augmentation directly into the pipeline, and connect datasets seamlessly with Keras model training.
