Age	Commit message (Collapse)	Author
2024-09-17	add: onehot implementation done	jvech
	parse.c test code was deleted too
2024-09-14	feat: onehot feature implementation in process	jvech
	To make onehot available I had to refactor how the data is stored, the current implementation supports json files.
2024-09-08	fix: file_read() and file_write() refactor	jvech
	Functions Parameters were replaced by Configs struct to allow scalability, in the future I might merge parse.c source code into util.c
2024-09-08	fix: memory leaks fixed	jvech

2024-09-04	fix: ml_network_train() refactored	jvech

2024-09-03	feat: shuffle dataset on each epoch done	jvech
	The CLI option to disable it was also added.
2024-08-26	add: mini batch learning implemented	jvech

2024-08-07	add: CLI improvements and small documentation updates	jvech
	Things done: * config path should search config file in the following order: cli option, environment, xdg_path * Implement a retrain command. * when you require more keys than the ones available in the input, stop the program.
2024-08-06	add: file parsing improved	jvech
	Things implemented: * json_read() must die if the key does not exist or the value type is wrong. * on predict command input should be shown exactly the same * float precision CLI option should be added.
2024-07-26	add: file_write() implemented	jvech
	things implemented: - CLI option --only-out added - CLI option --format works more intuitively - csv tsv and json output support
2024-07-24	add: file_read() and format integraded on main program	jvech
	things implemented: - read output in false bug was solved. - Make generic rule added to build test executables - format option added to the CLI
2024-07-24	add: file_read() function implemented	jvech
	things implemented: - Automatic file format infering - json_read() small refactor done - error checking in csv_read() improved
2024-07-23	add: csv_read() improved	jvech
	Error messages are more specific and now columns are read as arrays of strings.
2024-07-23	add: read_csv function added	jvech
	There is still much to do
2024-07-19	add: tanh activation added	jvech

2023-10-21	setup: man page improved	jvech
	Documentation: Example sections was improved Files sections was added Fixes: default config filepath was fixed
2023-10-21	setup: Install and uninstall rules added	jvech
	The man page must have a section specifying where to save configurations files for loading the network architecture and weights.
2023-10-18	doc: README added	jvech
	Installation and uninstallation rules must be added on Makefile

2023-08-27	add: data and network initialization done	jvech
	train subcommand can read and train the network TODO: - Refactor json_read() to parse multiple labels - Implement a function to save network weights once the network have trained - Implement a function to load trained weights to use with predict subcommand

2023-08-23	add: basic configuration parsing implemented	jvech
	parameters implemented: - input_keys - label_keys - epochs - labels - weights_path Network weights and architecture loading is not implemented yet.
2023-08-17	[ADD]: Cli implemented in a different function	jvech
	The program config parameters where encapsulated in a struct to keep track of them without implementing a lot of functions
2023-08-16	add: Cli defined	jvech
