Deep Neural Nets with Randomized Learning Techniques

Deep Neural Nets with Randomized Learning Techniques











Deep neural nets (DNNs) have undoubtedly established themselves as outstanding tools in the machine learning community. Training DNNs by millions of instances however leads to a huge computational burden due to the fact that gradient descent algorithms need a quite large number of iterations before finding a local minimum/maximum solution, even with modern GPU/TPU hardware acceleration. Some researchers and practitioners have attempted to use randomized learning techniques (RLTs) to develop fast algorithms for training DNNs (in a broad sense, random weight initializations used in training DNNs in practice can be viewed as RLTs). Others have paved the way for studying theoretically the capability of DNNs, especially the modern over parameterized ones exhibiting certain intriguing phenomena such as the ability to fit random labels and double descent. It is important, for both the academic and industrial communities, to investigate theoretically the principles behind the feasibility of randomness in DNNs (e.g., what are the representational capabilities of DNNs with some randomly assigned weights) and to develop advanced randomized learning techniques capable of building powerful DNNs that avoid high computational cost. Another important point is the empirical demonstration of the good potential of randomized learning techniques/strategies for speeding the training of DNNs without decreasing the performance and further verify their possible advantages for real world applications with large scale training dataset setups and/or real time processing requirements. This session calls for contributions which provide theoretical studies and fundamentals, algorithmic developments with advanced applications, implementation and design of user friendly computing tools/platforms, to boost the usage of randomized learning techniques in DNNs and further motivate new insights/interpretations for the role of randomness in DNNs.
