Our work titled "Binary-Stochasticity-Enabled Highly Efficient Neuromorphic Deep Learning Achieves Better-than-Software Accuracy" has been published in Advanced Intelligent System.
A new learning algorithm for in-memory learning in RRAM based neuromorphic network is proposed. All signals, including forward signals, backward errors, derivatives of activation fuction are highly quantized, i.e. binarized, with the help of device noise. The hardware implementation of a neural network is highly efficient and can have better performance than the floating-point conterpart in software. Thanks for the hardwork by Dr. Yang Li and other collaborators.

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.
