Seminar "Deep Scene Perception without Labeled Data"
On November, 25th at 8.30, Prof. Luigi Di Stefano (University of Bologna) will give an invited talk on "Deep Scene Perception without Labeled Data". The event is organized as the fourth of a cycle of seminars on AI for Automotive, as part of the "Neural Network Computing, AI and Machine Learning for Automotive" and "Learning Algorithms for Smart Intelligent Systems" courses (Prof. Cucchiara, Baraldi) and will be streamed online.
Abstract
This talk will present the recent research work carried out at CVLab-University of Bologna in the field of deep learning for scene perception. The leitmotif behind our work concerns avoiding reliance on supervision from labeled data, which, indeed, I am lead to posit not to even exist when it comes to train models aimed at key perception tasks like depth prediction. Firstly, I will address depth estimation from both stereo as well as monocular views. Here, the main contribution of our research concerns deploying self-supervision to pursue domain adaptation of deep CNNs pre-trained on computer generated imagery. This, indeed, lead us to the development of the first-ever on-line adaptive stereo network, i.e. a CNN that deploys an efficient continual learning paradigm to keep-up with domain changes in real-time. As for depth-from-mono, based on the intuition that effective monocular depth cues arise from semantic knowledge, I will show how joint learning of depth and per-pixel class labels can ameliorate depth prediction significantly. I will then present our latest results dealing with the first CNN architecture for comprehensive scene perception from monocular videos: ΩNet (CVPR 2020) can predict depth, semantic labels, optical flow, per-pixel motion probabilities and motion mask based on a novel training protocol relying on self-supervision and knowledge distillation. To conclude the talk, I will briefly show some unpublished results from on-going projects carried out in cooperation with companies and discuss the issue of long-tailed distributions in AI for automotive.
