Python - Python NLP Libraries
TextBlob - Providing a consistent API for diving into common natural language processing (NLP) tasks. Stands on the giant shoulders of Natural Language Toolkit (NLTK) and Pattern, and plays nicely with bot.
spaCy - Industrial strength NLP with Python and Cython
textacy - Higher level NLP built on spaCy
gensim - Python library to conduct unsupervised semantic modelling from plain text
scattertext - Python library to produce d3 visualizations of how language differs between corpora
AllenNLP - An NLP research library, built on PyTorch, for developing state-of-the-art deep learning models on a wide variety of linguistic tasks.
PyTorch-NLP - NLP research toolkit designed to support rapid prototyping with better data loaders, word vector loaders, neural network layer representations, common NLP metrics such as BLEU.
Rosetta - Text processing tools and wrappers (e.g. Vowpal Wabbit).
PyNLPl - Python Natural Language Processing Library. General purpose NLP library for Python. Also contains some specific modules for parsing common NLP formats, most notably for FoLiA, but also ARPA language models, Moses phrasetables, GIZA++ alignments.

ArcFace: Additive Angular Margin Loss for Deep Face Recognition. The author used PyTorch 1.0 which is nice.

"We present arguably the most extensive experimental
evaluation of all the recent state-of-the-art face recognition
methods on over 10 face recognition benchmarks including
a new large-scale image database with trillion level
of pairs and a large-scale video dataset. We show that ArcFace consistently outperforms the state-of-the-art and can be easily implemented with negligible computational overhead. We release all refined training data, training codes, pre-trained models and training logs , which will help reproducet he results in this paper."

This week's #machinelearning Q&A is on Underfitting vs Overfitting -

πŸ’‘ How can you tell if your model is underfitting your data?

If your training and validation error are both relatively equal and very high, then your model is most likely underfitting your training data.

πŸ’‘ How can you tell if your model is overfitting your data?

If your training error is low and your validation error is high, then your model is most likely overfitting your training data.

πŸ‘‰ Do you have any favorite heuristics that you use to detect under and over fitting in your models?

Wishes for TensorFlow/Keras 🀞

- A full merge between Keras and TF
- Make the transition from Keras to custom layers seamless
- Less announcements and more clarity on the existing API family
- An official experimental toolbox (similar to the fastai library)

Protecting your #DeepLearning model will be the key area to focus on from cyber attacks to your models and algorithms.

Placing these is public cloud environments may severely affect your ability to protect these models and algorithms.

You need to prepare to defend these.

What are these adversarial attacks?

1. l2-norm attacks: in these attacks the attacker aims to minimize squared error between the adversarial and original image. These typically result in a very small amount of noise added to the image.
2. l∞-norm attacks: this is perhaps the simplest class of attacks which aim to limit or minimize the amount that any pixel is perturbed in order to achieve an adversary’s goal.
3. l0-norm attacks: these attacks minimize the number of modified pixels in the image.

Below is an example of an l2-norm attack where the left is classified as jeep but the right as a minivan.
