Detailed Description

Binary save/load of CNN weights and latest-model discovery.

Function Documentation

Find the most recently modified .bin file inside a directory.

Iterates over all regular files with a ".bin" suffix in dir and returns the one with the highest mtime.

Parameters

dir	Directory to search (e.g. "models/").
out_path	Buffer that receives the full path of the chosen file.
out_len	Size of `out_path` in bytes.

Returns: 0 if a file was found and written to out_path, -1 if the directory is empty or cannot be opened.

Here is the caller graph for this function:

int model_load	(	CNN *	net,
		const char *	path )

Load CNN weights from a binary file into net.

Validates the magic number and version before reading. If validation fails, net is left unchanged.

Parameters

net	CNN to load weights into. Must not be NULL.
path	Source file path.

Here is the caller graph for this function:

int model_save	(	const CNN *	net,
		const char *	path )

Save the weights of a trained CNN to a binary file.

Creates or overwrites the file at path. The directory must exist.

Parameters

net	CNN whose weights should be saved. Must not be NULL.
path	Destination file path (e.g. "models/my_model.bin").
