Definition

H5 files use the HDF5 (Hierarchical Data Format) standard to store neural network models, particularly popular with Keras and scientific computing applications.

How It Works

HDF5 organizes data in a file system-like structure with groups and datasets. For neural networks, it stores layer weights, model architecture, and training configuration.

The format supports compression, partial loading, and metadata storage alongside the model data.

Why It Matters

H5 files bridge deep learning and scientific computing, making them ideal for research applications. They handle large models efficiently and maintain compatibility across platforms.

Keras made H5 the standard for saving models before TensorFlow's SavedModel format emerged.
