Heartbreaker

Hey Welcome back! This week, plenty of Colab notebooks were released by various sources and someone actually built a minimized version of the Switch transformer in PyTorch. But first… a word from our sponsors:

If you enjoy the read, help us out by giving it a U+1F44FU+1F44F and share with friends!

The Continuing Story of Neural Magic

Around New Year’s time, I pondered about the upcoming sparsity adoption and its consequences on inference w/r/t ML models. Well, a “new” company is on the scene and they just open-sourced their code.

‘New’ is in quotes because they aren’t really new, their open sourced code is.

The company is Neural Magic.

Neural Magic

Neural Magic has 6 repositories available. Follow their code on GitHub.

github.com

Their core repos consist of

SparseML: a toolkit that includes APIs, CLIs, scripts and libraries that apply optimization algorithms such as pruning and quantization to any neural network.

SparseZoo: a model repo for sparse models.

DeepSparse: a CPU inference engine for sparse models.

Sparsify: a UI interface to optimize deep neural networks for better inference performance.

They currently support: PyTorch, Keras, and TensorFlow V1. U+1F648

Switch Transformer Implementation in PyTorch

There’s already a PyTorch implementation of the Switch Transformer but it’s a minimized version and doesn’t do parallel training. However it does perform the ‘switching’ as described in the switch paper from Google. You can follow their code snippets in the link below and execute their minimized version on Colab. Really cool U+1F525U+1F525.

Microsoft’s Multi-Lingual Spell Checker

With Bing search, 15% of queries submitted by customers have misspellings. And as a result, MS used inspiration from BART’s architecture to help scale up their search business. Read how Microsoft did it and how multi-lingual spell checkers can be scaled up.

Talking about spaCy… the ScispaCy library from AI2 has a new release based on the spaCy’s v3 release. If you want to check out the new v3 features from spaCy, check out their blog post here:

Large Database of 90M Indian Legal Cases

“Development Data Lab has processed and de-identified legal case records for all lower courts in India filed between 2010–2018, using the government’s online case-management portal — E-courts. The result: charges, filing, hearing and decision dates, trial outcomes, and case type details of 25 million criminal, and 65 million civil cases.”

OCR Library U+007C Azure

Azure bringing their new version of OCR to their computer vision library it includes:

• OCR for 73 languages including Simplified and Traditional Chinese, Japanese, Korean, and several Latin languages.
• Natural reading order for the text line output.
• Handwriting style classification for text lines.
• Text extraction for selected pages for a multi-page document.
• Available as a Distroless container for on-premise deployment.

Topic Modeling

What to know what cross-lingual zero-sot topic modeling is all about? The model is called ZeroShotTM, based on multi-lingual encoder models. Imagine you want your model to learn topics in the English language and then you want it to predict unseen topics in Italian documents it has also never seen. This is essentially what cross-lingual zero-shot is all about. You can read their blog post U+1F447 which features a nice tutorial for you to get familiar with their library:

In this blog post, I discuss our latest published paper on topic modeling:

Dataset of the Week: ARC Direct Answer Questions

What is it?

A dataset of 2,985 grade-school level, direct-answer (“open response”, “free form”) science questions derived from the ARC multiple-choice question set released as part of the AI2 Reasoning Challenge in 2018.

Sample

{
 "question_id": "ARCEZ_Mercury_7221148",
 "tag": "EASY-TRAIN",
 "question": "A baby kit fox grows to become an adult with a mass of over 3.5 kg. What factor will have the greatest influence on this kit fox's survival?",
 "answers": [
 "food availability",
 "larger predators prevalence",
 "the availability of food",
 "the population of predator in the area",
 "food sources",
 "habitat",
 "availability of food",
 "amount of predators around",
 "how smart the fox is"
