Modern NLP: A Detailed Overview. Part 2: GPTs

Towards AI

Semi-Supervised Sequence Learning As we all know, supervised learning has a drawback, as it requires a huge labeled dataset to train. Generating Wikipedia By Summarizing Long Sequences This work was published by Peter J Liu at Google in 2019. But, the question is, how did all these concepts come together?

What Is a Transformer Model?

Hacker News

“Transformers made self-supervised learning possible, and AI jumped to warp speed,” said NVIDIA founder and CEO Jensen Huang in his keynote address this week at GTC. Transformers are in many cases replacing convolutional and recurrent neural networks (CNNs and RNNs), the most popular types of deep learning models just five years ago.

RLHF vs RLAIF for language model alignment

AssemblyAI

Using such data to train a model is called “supervised learning” On the other hand, pretraining requires no such human-labeled data. This process is called “self-supervised learning”, and is identical to supervised learning except for the fact that humans don’t have to create the labels.

What Is ChatGPT Doing … and Why Does It Work?

Hacker News

It’s better than the top-word (zero temperature) case, but still at best a bit weird: This was done with the simplest GPT-2 model (from 2019). And many of the practical challenges around neural nets—and machine learning in general—center on acquiring or preparing the necessary training data. Here’s a random example.

Meet the Winners of the Youth Mental Health Narratives Challenge

DrivenData Labs

I love participating in various competitions involving deep learning, especially tasks involving natural language processing or LLMs. I generated unlabeled data for semi-supervised learning with Deberta-v3, then the Deberta-v3-large model was used to predict soft labels for the unlabeled data.

An ML-based approach to better characterize lung diseases

Google Research AI blog

In “ Inference of chronic obstructive pulmonary disease with deep learning on raw spirograms identifies new genetic loci and improves risk models ”, published in Nature Genetics , we’re excited to highlight a method for training accurate ML models for genetic discovery of diseases, even when using noisy and unreliable labels.
