A Fruit Fly Circuit as a Speech Emotion Reservoir

Researchers at ORUK, in collaboration with FlyEM at Janelia, Cambridge, the MRC Laboratory of Molecular Biology, and Google Research, have developed a speech emotion classifier using a 499-neuron circuit from the male fruit fly brain, which is fully connected with 15,865 connections built from 867,344 synaptic contacts. The circuit, mapped by FlyEM, was wired into the classifier using reservoir computing to identify human emotions such as happy and angry from voice inputs.

A Fruit Fly Circuit as a Speech Emotion Reservoir We taught a fruit fly to hear human emotion https://oruk.ai/research/we-taught-a-fruit-fly-to-read-human-emotion uses a 499-neuron circuit from the male fruit fly brain and central nervous system, mapped by FlyEM at Janelia with Cambridge, the MRC Laboratory of Molecular Biology, and Google Research. The circuit is fully connected: every neuron can reach every other neuron through a directed path, across 15,865 connections built from 867,344 synaptic contacts. The team wired this circuit into a speech emotion classifier using reservoir computing and an identify human emotion like happy, angry from voice inputs.
