报告摘要：Current interaction with machine learning systems are mostly batch-based. A system takes a set of annotated data as input, and returns a trained model. This model is problematic because the annotation process is labor intensive and the training process works as a black box, making it difficult to understand and control. We are developing techniques to address these problems by introducing rich visual interaction techniques to help users understand and control machine learning systems. In this talk, I will present some of the results from our group in computer graphics.

报告摘要：通过脑机接口，人脑和外部设备之间可以直接进行交互，从而实现脑智能和机器智能的融合，即混合智能。混合智能是人工智能一种新的形态和方向，具有广泛的应用前景。提高目标检测性能和实现多维控制是脑机接口研究的两大基本问题。我们首先介绍多种多模态脑机交互，包括基于SSVEP和P300的脑机接口，视听觉脑机接口，基于P300和运动想象的脑机接口，这些脑机接口或者可以提高目标检测性能，或者可以实现多维控制。然后我们介绍这些脑机接口两个方面的临床应用：（1）意识障碍患者（如植物人等）的意识检测是一个难点问题，主要原因是这些病人缺乏行为能力，认知水平低下。我们开发了多种脑机接口,用于意识障碍患者（如植物人等）的意识检测,数字认知检测、临床辅助诊断,取得了良好效果。（2）面向严重的颈椎损伤的高位截瘫病人，我们开发了环境控制系统。该系统集成轮椅、家电和护理床于一体，实现了脑控，有效提高了这些病人的生活自理能力。

报告摘要：Over the last decades, the success in the field of visual computing has revolutionized our digital visual experience --- from special effects in Hollywood movies, face recognition on smartphones, to the stunning promise offered by VR/AR goggles. Yet, in this grand picture, one piece remains missing --- the sound. Our real world has never been silent. Not only is it colorful to our eyes, its sound is also rich and vivid to our ears. In current paradigms, visual computing is often performed in isolation from its audio counterparts. In this talk, I will propose audiovisual computing, a research area that renders, analyzes, and processes audiovisual information. I will first introduce our recent works in this area on physics-based audiovisual models from first principles, and then illustrate audiovisual processing using our work on 360 videos. In the second part of the talk, I’ll discuss the implication of these models on improving the physical world --- namely how to harness the computational audiovisual models to enable tangible forms and objects that offer unprecedented new functionalities.

报告摘要：The importance for simulations, in both robotics and more recently autonomous driving, has been more and more recognized. In this talk, I will talk the fairly extensive line of simulation research at Baidu’s Robotics and Autonomous Driving Lab (RAL), from low-level sensor simulation, such as LIDAR, to high-level behavior simulation, such as drivers/pedestrians. These different simulations tools are designed to either produce an abundant amount of annotated data to train deep neural network, or directly provide an end-to-end environment to test all aspects of robots/autonomous vehicles movement capabilities.

报告摘要：RGB multispectral video that span the visible electromagnetic spectrum (400 nm - 700 nm) are now commonplace, with the advent of color video cameras. Near, mid, far Infrared (IR) hyper spectral imaging, that capture a portion of the human invisible spectrum (700 nm - 1mm) have additionally proven indispensable for many scenarios such as night vision, video surveillance, terrain sensing via satellites. Both multispectral and hyper spectral forms of imagery are now seeing use for navigation/control, in automobiles, transport vehicles and even drones. This spectral imagery, enables the simultaneous prediction of the visible and invisible geometry and material properties of complex scenes. This talk shall dwell on the success, and current challenges of state of the art, machine learning algorithms for spectral de-noising, semantic segmentation, data fusion, super-resolution.
