Meeting Notes 18-01-2020
- Multilabel classification review by @gagan
- Segmentation classification notebook walk-through by @gagan
- Image Regression notebook walk-through by @Shahnoza
Advice
- Familiarizing ourselves with DataBlock API (https://docs.fast.ai/data_block.html)
- Experimenting with learning_rate using pct_start (https://forums.fast.ai/t/what-is-the-pct-start-mean/26168/6)
Discussion
- Class Imbalance : Doesn’t appear to be valid for images. Research suggests that it might be valid for tabular data. Further exploration required.
- Partial functions : Concept review by @gagan (Used in multi-class classification)

We are deciding timing for the next meetup, please write your suggestions in the comments or vote in the slack The meetup will be dedicated to Lesson 4
Curious general question: how do you guys keep track of changes in your model. For instance, when you change parameters or change resnet#. Do you guys save the graph in word document, use a software to compare different runs or what do you guys do?
Personally, i had been trying to use Wandb to compare different models but still trying to learn how to use different features. For instance, if i wanted for it to grab a graph of a certain run and the others to compare how its changing.

Meeting Minutes for 01/26/2020
Presentation on Lesson 4
- fastai lesson 4 by @Tendo Colab notebook with explanation
- @Tendo also shared Colab for Amazon Review Sentiment Analysis
Questions
The ImageDataBunch creates a validation set randomly each time the code block is run. To maintain a certain degree of reproducibility the np.random.seed() method is built-in within the fastai library.
- How to stop Google Colab from disconnecting?
@vijayabhaskar shared this in the previous comment
Challenges
- Many participants shared the common challenges that they face. This deserves a separate post (will summarize this & possible options soon)
Misc

I wrote my first post using the fast_template shared by Jeremy, which uses Github pages and Jekyll. I hope it can be helpful to people.

Thanks @mrfabulous1!! I’m glad you found it useful. !!
Hi people!!! As part of this study group, we are starting an algorithms meetup to hone our expertise in using data structures and algorithms, which can be useful for interviews as well.
Preparing for Leet-code styled coding interviews can be a very challenging task because the material is scattered and finding the perfect explanation for the problem can take time. I, along with a friend prepared for these interviews and I intend to cover some patterns that we learnt, (related to data-structures and algorithms) that were useful to us. We both got a new job after weeks of preparation and iteratively figuring out how not to fail. Please note that I will be just sharing my experience and by no means am I an expert (yet ). I hope my experience will help others in solving such coding problems and nailing that interview!!!
People who are interested can join the slack for our study-group using the link in the first post of this thread. (We would be using the #coding_interview_prep channel for this specific purpose)
