Optional "AI" Page

 

This page is only present if you installed one or more of the AI modules.

 

 

 

Interpreter's path

When using the AI modes, sliceOmatic need to know where the Python interpreter is located in your computer.

 

The program will locate this directory for you.  It can not be changed with this interface.

 

Python code path

The AI modes used Python files for the different models and metrics.  You need to specify the path to these files.  By default they are installed in a "SliceO_Python" sub directory of your scratch file.

 

AI temp folder

The AI modes will create a lot of temporary files (up to 100 set of files while training) and may need more than 20Gb of disk space!  By default this temporary folder is located in your document folder under "TomoVision\AI_Temp".

 

If your "Document" folder has been hijacked by OneDrive, it may be a good idea to place the temp folder somewhere else...

 

Validation history

During training, the program save the weights regularly, you can also have the program use these weights to predict the segmentation of the validation images at the same time.  The interface can then display these results, enabling you to follow the training's progress.

 

You have 3 choices:

•"off" disable the graphic prediction of the segmentation of the validation files. 

•"latest" only keep the the results for the latest epoch.

•"history" compute the values regularly and enable you to scroll through the different epochs.

 

Note:

The program save a maximum of 100 weights during training.  If you train for less than 100 epochs, you have one set of weights and potentially one set of segmentation results for each epochs.  If you train for more than 100 epoch, then you have a save each (nb epoch/100) epochs.

 

Note:

With the "history" option, the program save the TAG files for each validation image each time it save the training weights.  For example, if you have 10 validation images, the program will save 100 set of weights and 100x10 TAG files.  If you use this option, make sure you have abundant space on your disk for the AI temp folder!
