**HeliaEdge** is a [Keras 3](https://keras.io) add-on focused on training and deploying models on resource-constrained, edge devices. Helia relies heavily on [Keras 3](https://keras.io) leveraging its multi-backend support and customizable architecture. This package provides a variety of additional models, layers, optimizers, quantizers, and other components to help users train and deploy models for edge devices.

## Problems **HeliaEdge** looks to solve

### Compatability issues between frameworks and inference engines

- [x] By leveraging Keras 3, entire workflows can be run using a variety of backends using a consistent front-end API. This allows selecting a backend that plays nicely with a specific inference engine without rewriting the entire model.

### SOTA models dont scale down well and come in limited configurations

- [x] By providing highly parameterized model architectures based on SOTA models, users can easily scale down models to fit their needs.

### Limited 1D time-series models

- [x] Most included models in HeliaEdge provide both 1D and 2D versions. The package also contains time-series specific models.

### Limited support for quantization, pruning, and other model optimization techniques

- [x] HeliaEdge provides a variety of quantization and pruning techniques to optimize models for edge deployment.
