Field Documentation

◆ devices

sb_t_devices_par sb_t_svl_par::devices

Devices used for SVL/training.

Used by the function sb_svl_run in case of Deep Cortex and Deep Surface projects. Currently only a single device is admitted.

Warning: Incremental svl results my be affected by a fall down of the accuracy and an increase of the loss, if the type or index of the device is changed.

Definition at line 9265 of file sb.h.

◆ dl

sb_t_svl_dl_par sb_t_svl_par::dl

Deep Learning SVL parameters.

Training parameters used only by Deep Cortex and Deep Surface projects.

Definition at line 9277 of file sb.h.

◆ fp_command

sb_fp_svl_command sb_t_svl_par::fp_command

Callback called by SVL to allow the user to decide how to continue when particular situations happen, see sb_t_svl_stop_reason .

See also: SVL Callbacks

Definition at line 9204 of file sb.h.

◆ fp_pre_elaboration

sb_fp_svl_pre_elaboration sb_t_svl_par::fp_pre_elaboration

Callback to execute an image pre elaboration.

See also: SVL Callbacks

Definition at line 9192 of file sb.h.

◆ fp_progress

sb_fp_svl_progress sb_t_svl_par::fp_progress

The SVL calls this callback to notify the user the results of SVL.

See also: SVL Callbacks

Definition at line 9198 of file sb.h.

◆ free_memory_percentage

float sb_t_svl_par::free_memory_percentage

Percentage of system memory that the svl tries to leave free.

When the free physical memory drops below this percentage, the SVL starts to save on disk its data. Value between 0 and 1.

Definition at line 9230 of file sb.h.

◆ image_ext

char sb_t_svl_par::image_ext[64]

Extensions of the images.

List of the extensions of the images that the function sb_svl_run searchs in the project_path.
See SB_IMAGE_FILE_EXTENSIONS for a complete list of the possible extensions.

See also: Loading an image from file

Definition at line 9223 of file sb.h.

◆ num_threads

int sb_t_svl_par::num_threads

Maximum number of OpenMP threads that SVL can use.

The value 0 means: half of the available threads for physical machines and all available threads for virtual machines.
The default value is 0.

See also: License configurations; Parallel computing

Definition at line 9239 of file sb.h.

◆ reproducibility

int sb_t_svl_par::reproducibility

Enable the reproducibility of the training.

If enabled, training results are repeatable for all the SVL runs, provided that sb_t_svl_par and the dataset are the same.
Otherwise, some random initializations are applied during SVL, leading each time to different training results.
The possible values are:

0: disabled
!= 0: enabled

Attention: For Deep Cortex and Deep Surface projects reproducibility is guaranteed only on CPU computational devices and when all parameters of the structure sb_t_svl_par being equal. For example, the svl results also change with different number of threads.
Moreover reproducibility is guaranteed only on the same machine and not between different machines.
For example, trainings done on the same Virtual Machines on different Intel-based computers are reproducible.

Definition at line 9255 of file sb.h.

◆ sl

sb_t_svl_sl_par sb_t_svl_par::sl

Shallow Learning SVL parameters.

Training parameters used only by Deep Cortex and Surface projects.

Definition at line 9271 of file sb.h.

◆ user_data

void* sb_t_svl_par::user_data

Pointer to data which is passed to the callbacks.

See also: SVL Callbacks
