An ongoing challenge in neuromorphic computing is to devise general and computationally efficient models of inference and learning which are compatible with the spatial and temporal constraints of the brain. The gradient descent back-propagation rule is a powerful algorithm that is ubiquitous in deep learning, but it relies on the immediate availability of network-wide information stored with high-precision memory. However, recent work shows that exact backpropagated weights are not essential for learning deep representations. Here, we demonstrate an event-driven random backpropagation (eRBP) rule that uses an error-modulated synaptic plasticity rule for learning deep representations in neuromorphic computing hardware. The rule is very suitable for implementation in neuromorphic hardware using a two-compartment leaky integrate & fire neuron and a membrane-voltage modulated, spike-driven plasticity rule. Our results show that using eRBP, deep representations are rapidly learned without using backpropagated gradients, achieving nearly identical classification accuracies compared to artificial neural network simulations on GPUs, while being robust to neural and synaptic state quantizations during learning.

The generation of high quality true random numbers is essential in security applications. For secure communication, we also require high quality true random number generators (TRNGs) in embedded and IoT devices. This paper provides insights into modern TRNG design principles and their evaluation, based on standard’s requirements and design experience. We illustrate our approach with a case study of a recently proposed delay chain based TRNG.
