Webinar : fine-tune and deploy Hugging Face NLP models

Hugging Face
On a mission to solve NLP,
one commit at a time.

www.HuggingFace.co
Hugging Face is the most popular open source Natural Language Processing (NLP) library !
• Community model hub with more than 4,000 models
• More than 3To of models stored in the cloud
• More than 5 new models uploaded each day
• Founded in 2016
• 20+ employees

Natural Language Processing : the concept

NLP is broadly defined as the automatic manipulation of natural language,
like speech and text, by software. It’s a subset of artificial intelligence.
How do I say « Hello ! »
in Spanish ?
Output : « Hola! »
Natural Language Understanding Machine Learning Natural Language Generation

Let’s use NLP pre-trained models !

Use-case example #1 : sentiment analysis
Code sample
Use-cases
Analyze emails, product reviews, tweets, ... Then react :
 Brand : monitor your brand reputation on social medias
 E-commerce : remove bad products, highlight good ones
 Support team : priorize negative emails
 …

Use-case example #2 : question answering
Code sample
Use-cases
You can drastically improve user experience :
 Website : contextual « search engines »
 Internal documentation : easier to find what you need
 Voice Assistants (« Alexa, … » )
 …

.. And much more !
Use-cases
 Text Analysis : detect fake news, detect spams and scams, …
 Text Generation : better video games, better AI assistants, SEO, …
 Text Summarization : auto generated excerpts for products, for webpages,
for SEO, …

Remarks:
❏ The error rate goes down quickly! After one epoch we already have >90% accuracy.
⇨ Fine-tuning is highly data efficient in Transfer Learning
❏ We took our pre-training & fine-tuning hyper-parameters straight from the literature on
related models.
⇨ Fine-tuning is often robust to the exact choice of hyper-parameters
via Thomas Wolf

Transformers library
We’ve built an opinionated framework providing state-of-the-art general-purpose tools for Natural Language
Understanding and Generation.
Features:
 Super easy to use – fast to on-board
 For everyone – NLP researchers, practitioners, educators
 State-of-the-Art performances – on both NLU and NLG tasks
 Reduce costs/footprint – 30+ pretrained models in 100+ languages
 Deep interoperability between TensorFlow 2.0 and PyTorch
