Facebook’s Generative Facelift: All about the AI upgrades of Meta's Messenger, WhatsApp, and Instagram

Meta is rolling out AI-powered upgrades to its social platforms. Meta announced a chat interface, image generator, and celebrity tie-ins for Facebook, Instagram, Messenger, and WhatsApp. The new capabilities take advantage of LLaMa 2 and an unnamed image generator, presumably CM3leon.

Different Media, Similar Embeddings: ImageBind, the AI model that binds data from seven data types at once

The ability of OpenAI’s CLIP to produce similar embeddings of a text phrase and a matching image opened up applications like classifying images according to labels that weren’t in the training set. A new model extends this capability to seven data types.

Text-To-3D Animation: MAV3D, a method for generating 3D dynamic scenes from text descriptions

Text-to-video generation is so 2022! A new system takes in text and generates an animated 3D scene that can be viewed or rendered from any angle.

AI Firms Agree to Voluntary Guidelines: U.S. companies agree to uphold a list of responsible AI commitments.

In the absence of nationwide laws that regulate AI, major U.S. tech companies pledged to abide by voluntary guidelines — most of which they may already be following.

Where Is Meta’s Generative Play?: Why Meta still lacks a flagship generative AI service

While Microsoft and Google scramble to supercharge their businesses with text generation, Meta has yet to launch a flagship generative AI service. Reporters went looking for reasons why.

Collaborative Text Generator: A language model that collaborates with human writers

Text from current language models can be useful as a rough draft, but that leaves the polishing to human writers. A language model learned how to generate and respond to editorial directions.

Runaway LLaMA: How Meta's LLaMA NLP model leaked

Meta’s effort to make a large language model available to researchers ended with its escape into the wild. Soon after Meta started accepting applications for developer access to LLaMA, a family of trained large language models...

Streamlined Robot Training: Robots trained in lo-fi simulation perform better in reality.

Autonomous robots trained to navigate in a simulation often struggle in the real world. New work helps bridge the gap in a counterintuitive way.

Unsupervised Data Pruning: New method removes useless machine learning data.

Large datasets often contain overly similar examples that consume training cycles without contributing to learning. A new paper identifies similar training examples, even if they’re not labeled.

Language Models Defy Logic: Large NLP models struggle with logical reasoning.

Who would disagree that, if all people are mortal and Socrates is a person, Socrates must be mortal? GPT-3, for one. Recent work shows that bigger language models are not necessarily better when it comes to logical reasoning.

Memorize Less; Retrieve More: How small language models can perform specialized tasks.

Large language models are trained only to predict the next word based on previous ones. Yet, given a modest fine-tuning set, they acquire enough information to learn how to perform tasks such as answering questions.

Translating a Mostly Oral Language: How Meta Trained an NLP Model to Translate Hokkein

Most speech-to-speech translation systems use text as an intermediate mode. So how do you build an automated translator for a language that has no standard written form? A new approach trained neural networks to translate a primarily oral language.
