Collective Visual Inference

报告摘要:In this talk, we will examine the problem of collective visual inference across a set of images by exploiting the relations among them. Such relations exist in different forms, including commonly shared text keywords, co-occurrence of different visual entities, spatial geometric constraints, and temporal constraints, to mention a few. We argue that by leveraging such relations, and conduct visual inference collectively across all images, we can achieve better recognition accuracy than separately recognizing each visual entity in each image separately under the conventional visual recognition regime.
Using semantic inference in online photo collections in social media as a case study, we propose a family of networked latent topic models, dubbed the name Visual Topic Network, for joint semantic inference across a collection of images. Our systematic study reveals that modeling such relations for collective inference can effectively facilitate to learn better visual representations, and hence improve recognition accuracy. I will also briefly discuss the potential application of such networked topic models for the task of inferring intended and perceived perception of images in social media.
If time permits, I will also briefly introduce some of the other research works I have conducted that are related to collective visual inference.

Computer Graphics for All

报告摘要 :Computer graphics is everywhere, movies, video games, mobile APPs, etc. However, very few people create computer graphics, because graphics software are traditionally designed for and can only be used by professional users. Driven by the rapid development of senor technologies, enormous Internet data, as well as emerging applications like 3D printing and VR/AR, computer graphics research is evolving into a new era - we are dreaming to make everyone create visual contents in their daily lives, not only in the digital world but also in the real world. In this talk, I will briefly review several projects we recently conducted to make this dream a reality. The underlying trend of this line of research is the fusion of computer graphics, computer vision, and digital fabrication.

Perceiving and Interacting with Images

报告摘要 :In this talk, I will introduce our latest research in image scene understanding and interactive technologies. Our first line of research aims at rapid image scene understanding based on visual attention mechanism (IEEE TPAMI 2015, IEEE CVPR 2014 Oral). Instead of specific algorithm design, I would like to highlight how these algorithms can be robustly used in various applications, including image composition, photo montage, image retrieval, object detection, semantic segmentation, and even deep learning. Our second line of research aims at intelligent image manipulation mechanism. We try to explore smart image manipulation techniques for easily obtaining annotated data during users’ nature interaction with the real world (ACM TOG 2014, ACM TOG 2015), which is partially motivated by the growing requirement of high quality labeled training data (expensive to be collected) for scene understanding.

Sparse Image Restoration: Challenges, and Our Advances

报告摘要:Despite the extensive researches of image restoration in the past decades, image restoration still remains a challenging problem due to its ill-posed nature. This talks will fist briefly introduces the challenges of the image restoration problems, and then moves to the introduction of our recent advances in the topics of image restoration, especially focusing on the structured sparse prior of natural images using the tools of statistical modeling (i.e., parametric sparse distributions). We will specially show that the learned shallow sparse model can achieve competitive and even better image restoration performance than the deep learning based methods in the context of image super-resolution.

Human visual perception of biological motion

报告摘要:Humans are remarkably adept at recognizing the motion of biological entities in complex visual scenes. Biological motion can be captured with a handful of point lights attached to the head and major joints of the body, and can be further decomposed into two components: global configuration and local motion. Whereas most previous studies have emphasized the contribution of global form to biological motion perception, our recent work indicates that local motion carries unique biological properties that can be processed independent of global configuration. Taken together, these findings suggest that biological motion perception is a multilevel course encompassing the processing of both global configuration and local motion.

低秩表示与视觉分析

报告摘要:机器学习中的研究课题是根据数据的特点制定的,比如数据的多子空间结构对应子空间聚类、数据的高噪性对应数据恢复、数据大尺度性对应大尺度学习、数据的实时性对于在线学习、等等。但是,数据的多种特点不是孤立存在的,而是同时存在的。然而,大多数现有方法只考虑了数据的某一种特点,不能很好地处理实际数据。我们提出低秩表示 (Low-Rank Representation / LRR)模型,同时考虑数据的多子空间结构与高噪性特点,把子空间聚类与数据恢复统一到低秩学习框架下,从理论上分析LRR的统计性能,为求解LRR中的优化问题提出一种快速优化方法,建立LRR中的字典学习理论与方法,并把LRR扩展应用于人脸识别、图像分割、图像去糊等应用性问题。

What’s the insight of self-paced learning

报告摘要:Self-paced learning (SPL) is a recently proposed learning regime inspired by the learning process of humans and animals that gradually incorporates easy to more complex samples into training. While several easy SPL implementation strategies have been proposed, it is still short of a general paradigm for guiding the construction of rational SPL learning regimes targeting specific applications. To resolve this problem, we provide an axiom for insightfully formulating the underlying principles of self-paced learning. This axiomatic understanding not only involves the previous SPL learning schemes as its special cases, but also can be utilized to extend a series of new SPL implementation regimes based on certain application aims. In the recent two years, we have constructed several SPL realizations, including SPaR, SPLD, SPCL, SPMF, based on this axiom, and achieved the best performance in several known benchmark datasets, e.g., Web Query, Hollywood2, and Olympic Sports. Especially, this paradigm has been integrated into the system developed by CMU Informedia team, and achieved the leading performance in challenging semantic query (SQ)/000Ex tasks of the TRECVID MED/MER competition organized by NIST in 2014.
In this talk, I’ll introduce some of our recent developments on the insightful understanding under SPL regime. We will use these results to explain the intrinsic reason why SPL can work in applications with highly noisy scenarios.

脑神经局部网络结构给神经计算的启示

报告摘要 :最近大脑的局部神经网络的解析工作进展很快。我想指出两个现在神经计算领域还没有广泛关注的相关问题。第一是反馈输入如何调制局部网络。我们提出了注意力神经网络框架。注意力神经网络是一种新的框架,将自上而下的认知偏差和自下而上的特征提取整合在一个统一的架构。当处理具有高背景噪声或困难的分割问题时,自顶向下的影响特别有效。我们的系统是模块化和可扩展的。这个框架很容易训练并且运行成本低廉,但可容纳复杂的行为。我们在MNIST变化数据集得到的分类准确度优于或同于其他最好结果,并可以成功分解重合的数字。另外一个是局部回路的解剖和生理结构在多个方面呈现对数正态分布,我将讨论其计算意义。

A Light Field Journey to Virtual Reality 虚拟现实的光场之旅

报告摘要:Light fields are image-based representations that use densely sampled rays as a scene description. While the original goal of acquiring a light field is to conduct view synthesis and post-capture refocusing, recent studies have shown that light fields can be extremely useful in other computer vision applications, including stereo matching and 3D reconstruction, stereoscopy synthesis, saliency detection, surveillance, and recognition. In this talk, I present a light field approach for virtual reality (VR) and augmented reality (AR).
I first introduce a brief history of VR/AR and my personal experience on the evolution of their core technologies: acquisition, processing, and display. I then discuss the limitation of classical approaches and show why light fields provide a viable path. On the acquisition front, I present several light field capture systems developed by our group and others that can produce realistic 3D VR environment beyond regular 360 panoramas. On the processing front, I present several latest 3D reconstruction algorithms that exploit ray geometric structure and sampling patterns of light fields. On the display front, I show how light field head-mounted displays (LF-HMD) can provide unprecedented refocusing capability analogous to human eyes to significantly enhance visual realism. I will summarize my talk by discussing challenges and opportunities of light field based VR/AR approaches.

Discovering Visual Patterns in big Visual Data

报告摘要:Motivated by the previous success in mining structured data (e.g., transaction data) and semi-structured data (e.g., text), it has aroused our curiosity in finding meaningful patterns in non-structured visual data like images and videos. Although the discovery of visual patterns appears to be quite exciting, data mining techniques that are successful in business and text data may not be simply applied to image and video data that are usually described by high-dimensional features and exhibit spatial or spatio-temporal structures. Unlike transaction and text data that are composed of discrete elements without much ambiguity (i.e. predefined items and vocabularies), visual patterns generally exhibit large variations in their visual appearances and structures, thus challenge existing data mining and pattern discovery techniques. This talk will discuss our recent work of discovering and searching visual patterns in image and video data, as well as their applications in image search, video surveillance, and robotics.

Online Stochastic Linear Optimization under One-bit Feedback

报告摘要:In this talk, I will first give a brief introduction of online learning, including full-information online learning and bandit online learning. Then, I will study a special bandit setting of online stochastic linear optimization, where only one-bit of information is revealed to the learner at each round. This problem has found many applications including online advertisement and online recommendation. We assume the binary feedback is a random variable generated from the logit model, and aim to minimize the regret defined by the unknown linear function. To address this challenge, we develop an efficient online learning algorithm by exploiting particular structures of the observation model. Specifically, we adopt online Newton step to estimate the unknown parameter and derive a tight confidence region based on the exponential concavity of the logistic loss. Our analysis shows that the proposed algorithm achieves a regret bound of O(d√T), which matches the optimal result of stochastic linear bandits.

视网膜中的视觉信息处理

报告摘要 :视网膜是视觉神经系统的输入端,它不仅将光信号转化成为神经系统可以理解及处理的电信号,而且还对视觉信息进行相当程度的分类及预处理,从而加速大脑对视觉输入的反应。小鼠视网膜中有超过20种神经环路对外界图像中不同的视觉特征进行提取,这些经过不同环路处理的视觉信息由不同亚型的视网膜神经节细胞(RGC)传递到大脑。这些视网膜神经环路输出的视觉信息正在逐渐被解码,对它们的环路机制的了解也在逐步的完善中。我将对近年来这方面的研究进展做一个简要介绍,并汇报我们实验室对两种视网膜神经节细胞功能的研究结果。
