Our paper with the titile of "Neuromorphic Motion Detection and Orientation Selectivity by Volatile Resistive Switching Memories" is now published in Advanced Intellegent Systems.

In this paper we take inspiration from the biological DS ganglion cells in the retina, and demonstrate the motion detection in an artificial neural network made of volatile resistive switching devices with short-term memory effects. The motion detection arises from the spatiotemporal correlation between the adjacent excitatory and inhibitory receptive fields with short-term memory synapses, closely resembling the physiological response of DS ganglion cells in the retina. The work supports real-time neuromorphic processing of sensor data by exploiting the unique physics of innovative memory devices.

The paper is selected to the collection of Editor's Choice of Advanced Intellegent Systems.

I am awarded by the Andrew and Erna Finci Viterbi Fellowship for 2020-2021 academic year.

Andrew and Erna Finci Viterbi have a long history of supporting the Technion and Israel. The faculty of Electrical Engineering in Technion are now named after them. Andrew Viterbi is one of the cofounder of Qualcomm Inc. and invented the Viterbi algorithm, an important algorithm for wireless communication.

Here is more information about the Viterbis and their support to Technion, especially the support to the faculty of Electrical Engineering.
