De-novo Identification of Small Molecules from Their GC-EI-MS Spectra

arXiv.org Artificial Intelligence

Identification of experimentally acquired mass spectra of unknown compounds presents a~particular challenge because reliable spectral databases do not cover the potential chemical space with sufficient density. Therefore machine learning based \emph{de-novo} methods, which derive molecular structure directly from its mass spectrum gained attention recently. We present a~novel method in this family, addressing a~specific usecase of GC-EI-MS spectra, which is particularly hard due to lack of additional information from the first stage of MS/MS experiments, on which the previously published methods rely. We analyze strengths and drawbacks or our approach and discuss future directions.


Effective Theory of Transformers at Initialization

arXiv.org Artificial Intelligence

This introduction paves the way for our effective-theory analysis of the backward path in I 3, where we'll figure out how to scale a relative learning-rate factor for each group of model parameters in Transformers. A. Vanilla SGD The SGD update equation is given by θ µ(t) = θ µ( t 1) η t L A t θ µ null null null null θ = θ (t 1), (1.87) where the model-parameter index µ runs over all the P model parameters θ µ in the architecture, η t is a learning rate at iteration t, L A t denotes a loss function evaluated on a minibatch A t at iteration t, and θ µ(0) are drawn from the initialization distribution that was extensively discussed in I 1. 20 In this standard form, we assign the single learning rate η t for all the model parameters, but in theory we'll soon find that the learning rate for each group G of model parameters must be scaled differently as we embiggen Transformers.


ChatGPT Sparked a New AI Race and Revived the Popularity of Text Boxes

#artificialintelligence

Not even OpenAI comes close. Before it became the fastest-growing consumer app in history, before it popularised the phrase "generative pre-trained transformers," and before every company you can think of was racing to adopt its underlying model, ChatGPT debuted in November as a "research preview." In this article, we have explained how ChatGPT sparked a new AI race and revived the popularity of text boxes. Read to know more about ChatGPT sparked a new AI race. The blog post that announced ChatGPT has since become a hilarious case study in underselling.


If you want a career in AI, learn Python

No, AI isn't going to take your job. As I've written, the best uses of artificial intelligence and machine learning (AI/ML) complement human creativity rather than supplant it. People and robots are going to peacefully coexist for the foreseeable future. Even so, some industries are more aggressively embracing AI than others, as revealed in the newest 2022 AI Index Report from Stanford's Institute for Human-Centered Artificial Intelligence. During the past year, virtually every industry has increased its investments in AI-savvy people, with even higher AI-centric job postings from companies in the following industries: information (5.3%); professional, scientific, and technical services (4.1%); and finance and insurance (3.3%).


Will AI be bigger than the internet? How one Utah lawmaker is thinking about the future

#artificialintelligence

Editor's note: This is part of a KSL.com series looking at the rise of artificial intelligence technology tools such as ChatGPT, the opportunities and risks they pose and what impacts they could have on various aspects of our daily lives. SALT LAKE CITY -- Like all lawmakers in Utah's citizen Legislature, House Majority Whip Jefferson Moss spends most of the year working a day job. Moss, a Republican from Saratoga Springs, has a background in venture capital and technology, so he was quick to see the potential for artificially intelligent chatbots like ChatGPT when it was released last November. And while government as a whole can be slow to adopt new technology, Moss already sees recent breakthroughs in AI technology as huge leaps forward. "I've been following different iterations of AI, but when ChatGPT came out, it really was a game-changer," Moss told KSL.com in March.


Using ChatGPT is now a punishable offence - Gizchina.com

#artificialintelligence

Since its grand entry into the internet in November of last year, ChatGPT has been a phenomenon. This generative AI tool is good at writing papers, doing homework and helping wherever a student needs help. While many people laud ChatGPT, it remains a threat to academics. More universities around the world are now banning the use of ChatGPT. Some are even making its use a punishable offence, the same as plagiarism.


The Evolution of ChatGPT and Its Integration with Merlin AI

#artificialintelligence

In the world of Artificial Intelligence, two prominent platforms have emerged as leading game-changers: ChatGPT and Merlin AI. Both of these platforms have revolutionized the way we interact with technology and each other, providing businesses and individuals with unprecedented tools for communication, automation, and innovation. ChatGPT, developed by OpenAI, is an advanced language model based on the GPT-4 architecture. It is designed to understand, generate, and respond to human language with impressive fluency and accuracy. The success of ChatGPT lies in its ability to comprehend context, generate human-like responses, and adapt to various linguistic scenarios.

Speaker: Alison Gopnik, Distinguished Professor of Psychology, UC Berkeley Talk Title: Imitation & Innovation in AI: What Four-year-olds Can Do & AI Can't (Yet) About Talk: Young children's learning may be an important model for artificial intelligence (AI). Comparing children & artificial agents in the same tasks & environments can help us understand the abilities of existing systems & create new ones. In particular, many current large data-supervised systems, such as large language models (LLMs), provide new ways to access information collected by past agents. However, they lack the kinds of exploration & innovation that are characteristic of children. New techniques may help to instantiate child-like curiosity, exploration & play in AI systems.
