Neural Networks for Signal Processing - I

By Prof. Shayan Srinivasa Garani   |   IISc Bangalore
Learners enrolled: 2203
This will be an introductory graduate level course in neural networks for signal processing. The course starts with a motivation of how the human brain is inspirational to building artificial neural networks. The neural networks are viewed as directed graphs with various network topologies towards learning tasks driven by optimization techniques. The course covers Rosenblatt’s perceptron, regression modeling, multilayer perceptron (MLP), kernel methods and radial basis functions (RBF), support vector machines (SVM), regularization theory and principal component analysis (Hebbian and kernel based). Towards the end, topics such as convolutional neural networks etc. that are based on the MLP will be touched upon. The course will have assignments that are theoretical and computer based working with actual data.
INTENDED AUDIENCE: Graduate level, Senior UG can also participate, engineers and scientists within related industry. PREREQUISITES: Basic mathematical background in probability, linear algebra, signals and systems or equivalent. INDUSTRY SUPPORT: AI based, machine learning based.
