The earliest artificial neural network, the Perceptron, was introduced approximately 65 years ago and consisted of just one layer.  However, to address solutions for more complex classification tasks, more advanced neural network architectures consisting of numerous feedforward (consecutive) layers were later introduced. This is the essential component of the current implementation of deep learning algorithms.

Earth Day, celebrated on April 22, is an annual reminder of the critical environmental challenges facing humanity. In anticipation of the launch of the multidisciplinary School of Sustainability and Environment at Bar-Ilan University, Prof. Oren Perez emphasizes the "wickedness" inherent in environmental problems.
