Deep Learning forDense Per-Pixel Prediction and Vision-to-Language Problems


欢迎广大师生参会学校交流!


  

Abstract:

Dense per-pixel prediction provides an estimate for each pixel given an image,offering much richer information

than conventional sparse prediction models. Thus the Computer Vision community have been increasingly shifting the research focus to per-pixel prediction.

In the first part of my talk, I will introduce my recent work on deep structured methods for per-pixel prediction that combine

deep learning and graphical models such as conditional random fields. I show how to improve depth estimation from single images and semantic segmentation with the use of contextual information in the context of deep structured learning.

In deep learning, the trend towards increasingly deep neural networks has been driven by a general observation that increasing depth increases the performance of a neural network. Recently, however, evidence has been amassing that simply increasing depth may not be the best way to increase performance, particularly given other limitations.As a result, a new, shallower, architecture of residual networks is proposed, which significantly outperforms much deeper models on classification as well as semantic segmentation by a large margin.

Recent advances in computer vision and natural language processing (NLP) have led to new interesting applications.

Two popular ones are automatically generating natural captions for images/video and answering questions relevant to a given image

(i.e., visual question answering or VQA).

In the second part of my talk, I will describe several recent work from my group that take advantage of state-of-the-art computer visionand NLP

techniques to produce promising results on both tasks of image captioning and VQA.
