I work as a Principal Researcher at the Samsung AI center in Cambridge, UK., where I lead a group focusing on video anaysis, with special attention to human action analysis. This is scoped within the theme of the center, human-centric AI. Our task at SAIC-Cambridge is to solve the challenges stemming from Samsung's product family through technically novel approaches, and to produce technical advancements that can act as enablers for the development of future products. We publish our work on the top venues on computer vision and machine learning on a regular basis.
I am interested in a wide variety of topics in machine learning and computer vision - in fact most often it is the process, the team or the prospect of the impact that I find most appealing rather than the topic itself. While most of my work during my years in academia has been on face analysis, in recent years I have worked on topics as diverse as human action recognition, binary CNNs, knowledge distillation and lipreading.
This is my Google Scholar profile.
1 new paper on ICCV'21
One ICCV'21 on temporal action localization: Boundary-sensitive Pre-training for Temporal Localization in Videos
1 paper on ICASSP'21
Our work on Lipreading has been accepted for publication on ICASSP'21. See the arxiv version.
Two new ICLR'21 papers
One ICLR'21 on knowledge distillation: Knowledge Distillation via Softmax Regression Representation Learning
Code is publicly available here
One ICLR'21 paper on binary neural networks: High-Capacity Expert Binary Networks
I've been selected to act as Area Chair for the upcoming ICCV'21.
Organizing CVPR'21 Workshop
I'm co-organizing the 1st workshop on Binary Networks, to be held in conjunction with CVPR'21.
ECCV'20 paper accepted
BATS: Binary ArchitecTure Search has been accepted for ECCV'20.
Our paper on Binary CNNs has been accepted at ICLR'20. It sets a new state of the art for binary networks: 65.4% top-1 accuracy on ImageNet using a binary ResNet18 (an improvement of over 5%!).
Our paper on Lipreading has been accepted at ICASSP'20 for an oral presentation. It raises the state of the art on LRW and LRW1000 on 1.2% and 3.2% top-1 accuracy respectively. You can check out the arXiv version here.
Our paper on Action Recognition has been accepted at ICCV'19. We achieve 78.8 on Kinetics400 and 53.4 on Something-SomethingV1, and without even using two-stream or non-local NN. The paper can be accessed here.
Moving to Samsung
From April 2019 I'll be part of the Samsung AI Research Center in Cambridge, UK, on a new role as Senior Researcher.
Paper on ECCV'16
You can check it on Arxiv here: https://arxiv.org/abs/1608.01137
From June 2016 I'll be part of Amazon on a new role as Research Scientist. I'll thus be leaving my position at the University of Nottingham
I'm co-organizer of the Chalearn LAP and FotW challenge and workshop @ CVPR 2016
