Artificial Intelligence researchers at Open AI, a startup founded by Elon Musk, have discovered neurons within an AI system that have only previously been seen in human brains. According to a blog post, researchers uncovered what is referred to by neuroscientists as a ‘multimodal neuron’, within murky inner workings of one of its most advanced neural networks. researchers said that discovery was made using a general-purpose vision called CLIP, which trains itself on complex datasets to recognise objects and people within abstracts, such as cartoons or statues. 

In a tweet, Open AI said, “This discovery is an important step toward understanding associations and biases that large langu models learn during training, so we and or AI practitioners can ultimately make m safer”.

company said that y have discovered neurons in CLIP that respond to same concept wher presented literally, symbolically, or conceptually. researchers explained that discovery of multimodal neurons in CLIP gives m a clue as to what may be a “common mechanism of both syntic and natural vision of systems: abstraction”. In blog post, company informed that multimodal neurons were first discovered in human brain in 2005 when scientists realised that a single neuron could identify a common me through clusters of abstract concepts delivered through sensory information. 

researchers said that rar than millions of neurons working toger to identify a picture of a celebrity, just one neuron is responsible for recognising m. y furr added that this means that human brain has an individual neuron devoted to every family member, friend, celebrity that a person kws, with that neuron responding to photographs, drawings and ims of ir name but t or names. Furr, Open AI researchers found that similar to ir biological counterparts, artificial neurons also “respond to emotions, animals and famous people”.

Drawbacks of Neural networks 

It is worth ting that neural networks hold huge potential in development of an advanced artificial intelligence system. Open AI’s model was trained on a curated subject of internet, however, it inherits certain biases and associations that could prove harmful if it were to be used within commercial applications. company said that researchers have observed, for example, a ‘Middle East’ neuron with an association with terrorism and an ‘Immigration’ neuron that responds to Latin America.

researchers said, “We have even found a neuron that fires for both dark-skinned people and gorillas, mirroring earlier photo tagging incidents on or models we consider unacceptable”.
