I am part of the Advanced Processor Technology (APT) group here at The University of Manchester and I am supervised by Mr. Graham Riley and Dr. Mikel Lujan . My research is part funded by ARM and IS-ENES2 Project.
My research topic is "Efficient execution of Convolutional Neural Networks on low power heterogenous systems". If I had to sum up my research in three words, it would be Convolutional Neural Networks ( a.k.a "ConvNets"), Heterogenous Computing and Energy-Efficiency.
- ConvNets I became interested in Neural Networks during my undergraduate degree. Back then, I designed a Neural Net to act as a adaptive filter to cancel echoes from a voice signal with trailing echoes. Later, I joined The University of Manchester to do my Masters and my disseration revolved around "Transfer Learning" and "ConvNets" in the context of facial information processing. This project focussed on understanding whether transferring features in deep ConvNets would result in better feature extraction due to disentangling of informtation components (such as a person's identity, person's expression) found in the raw pixel representation of an image. Now, I am interested to get down to the nitty-gritty of the implementation of ConvNets and its execution behaviour on resource constrained devices.
- Heterogenous Computing We are now in the Many-core era with CPUs, GPUs, FPGAs all working together. I am interested in efficiently making use of these resources in the deploying algorithms such as ConvNets. One of the development boards I will get to play around with, is the Jetson TX1 that contains NVIDIA Maxwell GPU with 256 NVIDIA CUDA Cores and a Quad-core ARM Cortex-A57 MPCore Processor.
- Energy Efficiency I am interested in techniques to measure energy consumption during the inference of a ConvNet and mapping code phases to its energy profile and developing methods to exploit this information to enable better energy efficiency.
