When it comes to cyber hacks, NSA is the 3-letter agency to keep your eye on. And if you are wondering how they hack our emails, well, it involves clocks, prime numbers, and elliptic curves U+1F92F. In the video below, you will be introduced to the math used for creating random number generation used by cybersecurity algorithms for every-day encryption as used by credit cards or emails.

The reason why security software is efficacious is due to their encrypted “random” number sequences, which makes them unpredictable and hence, secure. But what if there is a backdoor to these random number generations so they become predictable? In essence, this is what the NSA figured out. To see how they did it, let’s go down the rabbit hole:

MMF Multi-Modal Framework

Hey Now! Facebook, more specifically PyTorch, have released their Multi-Modal Framework! It comes with…

“state-of-the-art vision and language pretrained models, a number of out-of-the-box standard datasets, common layers and model components, and training + inference utilities.”

You can use MMF for several different multi-modal tasks: VQA, image captioning, visual dialog, hate detection and others.

List of current available models:

  • M4C Iterative Answer Prediction with Pointer-Augmented Multimodal Transformers for TextVQA [arXiv] [project]
  • ViLBERT ViLBERT: Pretraining Task-Agnostic Visiolinguistic Representations for Vision-and-Language Tasks [arXiv] [project]
  • VisualBert Visualbert: A simple and performant baseline for vision and language [arXiv] [project]
  • LoRRA Towards VQA Models That Can Read [arXiv] [project]
  • M4C Captioner TextCaps: a Dataset for Image Captioning with Reading Comprehension [arXiv] [project]
  • Pythia Pythia v0. 1: the winning entry to the vqa challenge 2018 [arXiv] [project]
  • BUTD Bottom-up and top-down attention for image captioning and visual question answering [arXiv] [project]
  • MMBT Supervised Multimodal Bitransformers for Classifying Images and Text [arXiv] [project]
  • BAN Bilinear Attention Networks [arXiv] [project]

IR From Structured Documents

Remember OCR U+1F9D0? Some technologies never die, well Google has created a model for extracting information from structured documents. The architecture uses OCR to extract text from documents such as PDFs or scanned docs, afterward it uses a candidate generator to match fields from a target schema. In the end, fields are given a likelihood score to rank the extraction to the expected target.

SpaCy Update

SpaCy has a brand new update to its library highlighting new languages and tutorials (and more!). They added 5 new languages: Chinese, Japanese, Danish, Polish, and Romanian. In addition to new languages, SpaCy also improved model loading time and new online courses found here:

Long-Form Question Answering

Hugging Face recently released a demo for long form question answering which takes in a question, fetches passages from Wikipedia, and writes a multi-sentence explanation to the question. Meaning, this is not extractive QA like SQuAD-like models. Instead, it uses a sparse model (Elasticsearch) to retrieve top wiki passages that loosely link to the question and then use a dense model (Faiss) which embeds questions/answers trained on the ELI-5 dataset. In the end, they use BART for generating answers. Pretty cool and efficient!

Model Quantization in TF Lite

Great blog post from Sayak Paul on model quantization to be used for edge devices like mobile. It gives a lucid introduction to quantization (post-training quantization & quantization-aware training) and how it can fit with TensorFlow Lite.

Deep Learning in Production

Some sobering stats for AI models used in production such as “the majority of companies (59%) are not optimizing their machine learning models in production”(they should read the previous post on quantizationU+1F9D0) . If you enjoy anxiety, then check out these new survey results to see how enterprise developers are sweating bullets on the daily. FYI, TensorFlow is still popular in production.

Dataset of the Week: TVQA

What is it?

Dataset is used for video question answering and consists of 152,545 QA pairs from 21,793 clips, spanning over 460 hours of video.
