报告题目：归类问题研究
特邀讲者：于剑
报告摘要：
在大数据时代，如何从数据中提取知识是一个亟待解决的问题。而概念是知识的基本单位。 从数据中提取概念称为归类问题。 对于机器学习来说，归类通常包括数据降维、密度估计、回归，聚类和分类等问题。目前，针对归类问题文献中已经提出了众多的机器学习算法。这些算法的理论基础涉及面广，彼此之间的关系极其复杂。 本次报告试图提出一个统一的归类表示方法， 其基本假设是： 归哪类，像哪类；像哪类，归哪类。据此，首次建立了归类公理化体系。该公理化体可以推演出归类方法的三条设计原则，以统一的方式重新解释了数据降维、密度估计、回归，聚类和分类等问题，而且与日常生活中的认知原则一致。

报告题目：Self-paced Learning: Challenge and Opportunity
特邀讲者：孟德宇
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 will introduce some of our main developments along this line, and attempt to discuss several of the typical challenges and possible opportunities for future SPL research.

报告题目：
Multimodal Learning: From Image and Sentence Matching to Image Question Answering
特邀讲者：马林
报告摘要：
Deep neural networks have been successfully applied on single modalities, such as text, image, and audio. Nowadays, multiple modalities always accompany with each other, such as image and language, video and audio. Deep learning has been now studied for multiple modalities to study the association and correlation properties between them. In this talk, we discuss the multimodal learning, specifically the multimodal convolutional neural network (m-CNN), for image and sentence matching and image question answering. m-CNN provides an end-to-end framework with convolutional architectures to exploit image representation, word composition for sentence representation, and the matching relations between the two modalities. As such, the matching properties between image and sentence have been captured for the association between them. For bidirectional image and sentence retrieval, m-CNN achieves the state-of-the-art performances on Flickr8K, Flickr30K, and Microsoft COCO databases. For image question answering, m-CNN can fuse the multimodal input of the image and question to obtain the joint representation for the classification in the space of candidate answer words. The efficacy of m-CNN on DAQUAR and COCO-QA datasets is demonstrated, two datasets recently created for the image question answering (QA), with performance substantially outperforming the state-of-the-arts.

报告题目：深度学习及其在人脸识别上的应用
特邀讲者：山世光
报告摘要：
深度学习在语音、图像识别领域的成功已迅速影响了计算机视觉的各个研究方向。人脸分析和识别领域亦不例外。尽管简单照搬深度学习在其他视觉问题上的已有成功模型即已初显深度学习对于人脸判别特征提取的优异效果，但简单应用并不能解决所有问题。本报告将概述了近期我们在基于深度学习的人脸分析与识别方面的相关实践，包括面向人脸识别和表情识别的卷积神经网络特征学习，由粗到精的多阶段深度非线性人脸形状提取，以及姿态鲁棒的人脸特征渐进深度学习等。最后，总结了较小规模人脸数据条件下应用深度学习模型的有关经验。

报告题目: Saliency Object Detection: From Contrast-based methods to Supervised-based Methods
特邀讲者：卢湖川
报告摘要:
Saliency object detection, which aims to identify the most important and conspicuous object regions in an image, has received increasingly more interest in recent years. Salient object detection methods can be categorized as bottom-up stimuli-driven and top-down task-driven approaches. Bottom-up methods are usually based on low-level visual information and are more effective in detecting fine details. In contrast, top-down saliency models are able to detect objects of certain sizes and categories based on more representative features from training samples. In this talk, I would like to introduce Bayesian saliency、Manifold-ranking saliency and Markov-chain saliency which are all Contrast-based methods from the Bottom-up perspective and Bootstrap Learning saliency, Deep Learning saliency which are all Supervised-based methods from the Top-down perspective.
