Mohammad Shazri Shahrir is a research and development engineer currently leading the AI research cluster at Extol MSC Berhad, Malaysia. He has worked extensively on the artificial intelligent research projects particularly in pattern recognition. His work has included detailed analysis, design, augmentation and prototyping of the solutions in Quantum Cryptography, Signature verification, face recognition and verification, time tabling, etc. Shazri’s research interests include mathematical and machine learning theories and implementation such as Neural Networks, SVM, ARTMAP, AdaBoost, Bayesian Believe Networks, Principal Component Analysis, Fisher-Face , Eigen-face, Laplacian Face, Mahalonobis Distance, Solving Eigen-Problem, Quadratic Programming, Inverse of Arbitrarily Sized Symmetric Matrices, Primal-Dual Simplex, Integer Programming,Time-Tabling Problem, Image Manipulation, Discrete Fourier Transform, Wavelet Transform, etc.
Bayesian Neural Network
Regularization imposes stability on an ill-posed problem, the equation is ill-posed if it is not well-posed. The effect of regularization is the output smoothing of the neural network. With an attempt of smoothing, it improves the generalization of neural network by a mechanism to balance between how well the function fits the data and how smooth it is (penalizing using Bayesian prior). There are many approaches in regularization, namely Tikhonov Regularization, Iterative Regularization, etc. In this workshop, we will explore the Bayesian Regularization which imposes prior distributions on model parameters. The model parameters involved are the weights of the Neural Network.
