Efficient Training and Inference of Very Deep Convolutional Networks
Recent years have witnessed astonishing progress in convolutional neural networks (CNN). This fast development was largely due to the availability of training and inference of very deep models, which have even managed to surpass human-level performance on many vision tasks. However, the requirements for real world applications differ from those necessary to win competitions, as the computational efficiency becomes a major concern in practice. In the first part of the talk, I will introduce a stochastic depth network, which can significantly speed up the training process of deep models, making them more robust and generalize better. In the second part I will propose a densely connected network (DenseNet), which is inspired by the insights that we obtained from the stochastic depth network. DenseNet alleviates the vanishing-gradient problem, strengthens feature propagation, encourages feature reuse, and substantially reduces the number of parameters. The third part of the talk will focus on how to inference deep models under limited computational resources. I will introduce a multi-scale dense network (MSDNet) with shortcut classifiers, which facilitate retrieving fast and accurate predictions from intermediate layers, leading to significantly improved efficiency over state-of-the-art convolutional networks.

Egocentric Computer Vision, for Fun and for Science
The typical datasets we use to train and test computer vision algorithms consist of millions of The typical datasets we use to train and test computer vision algorithms consist of millions of consumer-style photos. But this imagery is significantly different from what humans actually see as they go about our daily lives. Low-cost, light wearable cameras (like GoPro) now make it possible to record people's lives from a first-person, "egocentric" perspective that approximates their actual fields of view. What new applications are possible with these devices? How can computer vision contribute to and benefit from this embodied perspective on the world? What could mining datasets of first-person imagery reveal about ourselves and about the world in general? In this talk, I'll describe recent work investigating these questions, focusing on two lines of work on egocentric imagery as examples. The first is for consumer applications, where our goal is to develop automated classifiers to help organize first-person images across several dimensions. The second is an interdisciplinary project using computer vision with wearable cameras to study parent-child interactions in order to better understand child learning. Despite the different goals, these applications share common themes of robustly recognizing image content in noisy, highly dynamic, unstructured imagery.
