Hi guys,

I’m experimenting with transfering Pytorch/Keras/TF models to Fastai. My last post was about molecule generation using LSTM. Today I bring you a Message Passing Neural Net for bioactivity prediction!

The model architeture comes from this paper: https://jcheminf.biomedcentral.com/articles/10.1186/s13321-019-0407-y

And you can find the original implementation here: https://github.com/edvardlindelof/graph-neural-networks-for-drug-discovery

For those of you looking for new, cool models to use for drug discovery studies using fastai, here’s my notebook showing the working model:

Hey guys!
I started a little project where I created a web app with binder to predict my ratings for a book given the text of an uploaded image.

I didn’t get the example of Jeremy working (voila_bears) so if anyone of you tries to make Binder work, check out my repo: https://github.com/lschmiddey/book_recommender_voila

My blogposts to this project can be found here: https://lschmiddey.github.io/fastpages_/2020/09/28/Build-binder-app-Part4.html

I hope you enjoy it!

Hi all,

I just published a two-part introductory article on building your own image classifier for deep learning beginners - if you’ve already completed Lessons 1-3 this is nothing new, but my target audience is myself before I started Deep Learning 2 years ago.

Its a hands-on article so it walks you through building a dataset and a model on Colab and running it on binder. If you have problems in the walk-through, I’d appreciate a comment so I can fix it…

Here’s the link : https://medium.com/@butchland/build-and-run-your-own-image-classifier-using-colab-binder-github-and-google-drive-part-1-bd1aebc626e

Best regards,

btw, forgot to mention :grinning: thanks to @joedockrill for the jmd_imagescraper package and @vikbehal for the binder instructions – hope you get to see your contributions in the article!

Best regards,
Butch

Hi all, my name is Dino and I am new to fastai. I absolutely love the material and the teaching style. I’ve read the first 7 chapters in the book and listened to the lectures online. Before moving further into the book, I decided to jump into a project and I was able to create a multilabel classification model on the “chinese-mnist” dataset. I would appreciate any feedback and I am really excited about moving forward with this course.

Hi All,

I have written a couple of blog posts explaining the workings of FastAI Optimizers and FastAI training loop. I have read the source code for these and have demonstrated my understanding with an Image classification example. Find the link to my posts below. Hopes this will be helpful.

  1. Study the resnet34 model architecture and build it using plain Python & PyTorch.
  2. Deep dive into FastAI optimizers & implement a NAdam optimizer.
  3. Study FastAI Learner and Callbacks & implement a learning rate finder (lr_find method) with callbacks.

Regards

I’ve written my blog around the stacking of tensors using PyTorch.

For e.g. I’ve used MNIST dataset. This is my first blog in deep learning. So, please give it a read and let me know if any changes need to be made.

Thank you :slight_smile:

Hey there, recently I wrote my first blog post on deep learning. In this post I investigated how a batch size affects learning when we train image classifiers on natural images: https://nikita.melkozerov.dev/posts/2021/01/transfer-learning-and-resnet-in-search-of-a-perfect-batch-size/

I continued to reflect my new knowledge in blog posts, so there is a new post about classifying digits from MNIST dataset from scratch. It was inspired by the chapter 4 of the fastbook, except this time we classify all 10 digits, and have some fun with different loss functions.

Hello friends! :grinning:

I recently started working through the fastbook, and created two posts covering chapters 4 and 5. Use the posts to supplement the videos, and please feel free to reach out if you have any feedback!
