AutoAI

This repository is a compilation of scripts that I have created in my time working with machine learning. These scripts aim to automate the annoying and silly parts of ML, allowing you to focus on what is important. PyPi: https://pypi.org/project/AutoAILib/
$ pip install autoailib

AutoAi.manual_test(model, testing_dir, labels)

This function tests a model given labels and testing data. It then compiles the results in a CSV file, and groups the results by class, and by correct and incorrect.

• Model - Path of model that you want to test or model object.
• Testing_dir - Path to the directory with your testing data.
• Labels - Dictionary of the classes, in form (index:class_name)

Example csv:

AutoAi.compile_data(src, dest, num_imgs_per_class=0, train_ratio=.7, validation_ratio=.2, test_ratio=.1)

This function takes 2 required arguments, an original data source file, and a path to the desired data directory. Given just these two arguments, this function will create a new testing data folder at dest with training, validation, and testing folders, containing folders for each class. You can alter the ratio with the ratio arguments, as well as provide a number of img transforms to do if you are using images.

• Src - Path to a folder that contains a folder for each class and then data examples in those class folders.
• Dest - Path to a folder where you want the data to end up.
• Num_imgs_per_class - This number of images will be added to the original set for each class through transforms. The theoretical limit for this would be 3! * original images per class

Demo:

Given the a path to the following folder: If augmentation used the following results will be yielded: Then these images will be copied to the dest folder with copied file structure, but an added upper layer: Example showing the images made it:

AutoAi.image_predict(model_path, image_path, labels)

This function takes 3 arguments: a path to a keras model, a path to an image, and a list of labels.

Demo:

Given a the correct arguments, we get the following output, as well as this image saved to our model directory.
