StripedHyena: A new architecture for next-generation generative AI?

Posted by in category: robotics/AI

GPT-4 and other models rely on transformers. With StripedHyena, researchers present an alternative to the widely used architecture.

With StripedHyena, the Together AI team presents a family of language models with 7 billion parameters. What makes it special: StripedHyena uses a new set of AI architectures that aim to improve training and inference performance compared to the widely used transformer architecture, used for example in GPT-4.

The release includes StripedHyena-Hessian-7B (SH 7B), a base model, and StripedHyena-Nous-7B (SH-N 7B), a chat model. These models are designed to be faster, more memory efficient, and capable of processing very long contexts of up to 128,000 tokens. Researchers from HazyResearch, hessian. AI, Nous Research, MILA, HuggingFace, and the German Research Centre for Artificial Intelligence (DFKI) were involved.

Researchers show an Old Law still holds for Quirky Quantum Materials

Posted by in categories: particle physics, quantum physics

Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat.

And in 1,853, two scientists showed that those two admirable properties of metals were somehow related: At any given temperature, the ratio of electronic conductivity to thermal conductivity was roughly the same in any metal they tested.

This so-called Wiedemann-Franz law has held ever since — except in quantum materials, where electrons stop behaving as individual particles and glom together into a sort of electron soup.

Tesla Cybertruck v F-150 Raptor R: DRAG RACE

Posted by in category: transportation

Pick-up truck fans let’s goooooo!! The Cybertruck is back once again, and it’s going head-to-head against one of the most powerful pick-ups money can buy — the Ford F-150 Raptor R! So let’s check out how these two almighty machines compare. Starting with the Tesla, we’ve got our hands on the ‘Cyberbeast’ tri-motor edition, which can produce 845hp and 930Nm of torque. This power is sent to all four wheels, and if you’re looking to pick one up it’ll cost you around $96,000.

It’s also pretty damn heavy, tipping the scales at 3,084kg!! Then alongside it we have the F-150. This Raptor R edition comes with a huge 5.2-litre supercharged V8 under the bonnet that can put down 700hp and 870Nm of torque. This power is sent to all four wheels via a 10-speed automatic gearbox, and this truck also comes in lighter than the Cybertruck, weighing in at 2,703kg.

OpenChat framework aims to optimize open-source language models

Posted by in category: robotics/AI

Researchers from Tsinghua University, Shanghai Artificial Intelligence Laboratory, and 01.AI have developed a new framework called OpenChat to improve open-source language models with mixed data quality.

Open-source language models such as LLaMA and LLaMA2, which allow anyone to inspect and understand the program code, are often refined and optimized using special techniques such as supervised fine-tuning (SFT) and reinforcement learning fine-tuning (RLFT).

However, these techniques assume that all data used is of the same quality. In practice, however, a data set typically consists of a mixture of optimal and relatively poor data. This can hurt the performance of language models.

Using hierarchical generative models to enhance the motor control of autonomous robots

Posted by in category: robotics/AI

To best move in their surrounding environment and tackle everyday tasks, robots should be able to perform complex motions, effectively coordinating the movement of individual limbs. Roboticists and computer scientists have thus been trying to develop computational techniques that can artificially replicate the process through which humans plan, execute, and coordinate the movements of different body parts.

A research group based at Intel Labs (Germany), University College London (UCL, UK), and VERSES Research Lab (US) recently set out to explore the motor control of using hierarchical generative models, computational techniques that organize variables in data into different levels or hierarchies, to then mimic specific processes.

Their paper, published in Nature Machine Intelligence, demonstrates the effectiveness of these models for enabling human-inspired motor control in autonomous robots.
