Fastai2 Visual Guide

[farid (Farid Hassainia)]

@rsomani95, DataBlock API is my first playground to create animations and related videos to make that material easier to understand for both fastai users who are transitioning towards fastai2, and newcomers who are outside the fastai ecosystem.

I’m planning extending that to other areas and covering more ground as long as it is doable in a timely fashion. My plan is also to cover the mid level API and show the connection with the high level API. I will also probably include some material that I shared in the Tips&Trick thread I created where I share stuff about both the hight-level and low-level API such the post about inference

Inference (Prediction)

This post describes how to get predictions from a test dataset, pretty-printing them, and plotting its corresponding confusion matrix when a test dataset has labels.

Or this one about spli_idx:

@farid

split_idx , or how to selectively apply a transform to train and valid (test) datasets?

split_idx allows a given Transform to be applied to a specific data subset: train, valid and test datasets. For example, it enables a specific image augmentation to be applied to only the train dataset and not to the valid dataset.

Having said that, creating those animations and videos involve a lot of work, and I’m creating them beside my own professional projects and my fastai2 project (timeseries). Therefore, my production will depend on many factors.

If other people would be interested in sharing their knowledge in the Tips&Tricks thread and/or initiatives, where we could centralize the knowledge in some easy-to-find sections, that would be great, and the whole fastai community will benefit from that.
