Machine Learning

---

The Machine Learning provides functions for ml.

Required Header

#include <hal-ml.h>

Overview

Tizen ML API may require a hardware device to accelerate its job. This HAL ML provides an interface for Tizen ML API (NNStreamer's tensor_filter subplugin) to use such hardware acceleration devices (NPU, ...) if available.

Typedefs
typedef struct _hal_backend_ml_funcs	hal_backend_ml_funcs
	The HAL backend structure for ML. This should be implemented by each HAL backend.
typedef enum hal_ml_error	hal_ml_error_e
	Enumeration for the error codes of hal-ml.
