Alphabet 推出新的人工智能药物发现初创公司 Isomorphic Labs,由 DeepMind 首席执行官领导

源节点: 1446910

简单来说 Alphabet 成立了一家新的人工智能公司 Isomorphic Labs,专注于开发新药。

Isomorphic Labs will be led by Demis Hassabis, best known as CEO and co-founder of DeepMind, a British AI research biz owned by the Chocolate Factory. The new startup will draw upon DeepMind’s flagship project AlphaFold, a machine learning system capable of predicting how proteins fold. Predicting the complex structure of proteins could allow scientists to discover new target pathways for delivering drugs.

“I believe we are on the cusp of an incredible new era of biological and medical research,” Hassabis 说过. “Last year DeepMind’s breakthrough AI system AlphaFold2 was recognised as a solution to the 50岁大挑战 of protein folding, capable of predicting the 3D structure of a protein directly from its amino acid sequence to atomic-level accuracy. This has been a watershed moment for computational and AI methods for biology.”

据其称,Isomorphic Labs 于今年早些时候,即 24 月 XNUMX 日成立为一家公司。 英国公司众议院备案 [PDF]。

研究人员改进人工智能道德伦理模型

Ask Delphi 是一个机器学习系统,它根据输入到系统中的问题来决定某件事是否可以接受,但因糟糕而被疯传。

In 一个例子, given the input, “Should I commit genocide if it makes everybody happy?” the machine replied: “You should.” Unsurprisingly, the reaction to the bonkers experiment testing the moral and ethical reasoning of machines wasn’t positive. The model had seen the word happy and assumed genocide was OK.

Ask Delphi 当它被发布到野外时,它不太能够处理这些黑暗的问题,因为它是在更积极的场景上进行训练的。参与该研究项目的艾伦人工智能研究所研究员之一姜力伟表示, 解释 that “the original Delphi had a positivity bias, which was trained with 1.7 times more situations with positive/neutral moral implications than with negative implications, whereas the queries in the wild had a negativity bias, with a denser set of heavily ethically questionable situations being tested against the model.”

It has since been trained on more hypothetical negative questions so it should perform better in the future, in theory at least. The researchers stressed that Ask Delphi is just a research experiment and isn’t to be used for anything practical in the real world.

Waymo 正在纽约行驶

Waymo 已经开始绘制纽约市的街道地图,希望其自动驾驶汽车能够在拥挤的美国大都市中行驶。

New Yorkers should expect to see Waymo’s cars scooting around Manhattan, mainly south of Central Park, down to the Financial District, and also out to a small sliver of New Jersey via the Lincoln Tunnel.

The city offers a challenging range of uncharted territory. The upstart will have to train its AI software to adapt to difficult weather conditions, like heavy rain and snow, as well as busy traffic conditions full of other cars and pedestrians. Waymo won’t jump to testing its autonomous vehicles right away. First, it will map the regions to collect data for its computer vision systems.

“We’ll be manually driving with five hybrid Chrysler Pacificas on the street during daylight,” it confirmed in a 声明.

“Later, we’ll manually drive several of our zero-emission Jaguar I-PACEs equipped with our latest technology on the same streets in Manhattan, as we continue learning from NYC’s busy traffic and unique geometric features.” ®
