Title: Toward Trustworthy Human-centered Behavioral Machine Intelligence

Abstract: Converging technological advances in sensing, machine learning and computing offer tremendous opportunities for continuous contextually rich yet unobtrusive multimodal, spatiotemporal characterization of an individual’s behavior and state, and of the environment within which they operate. This in turn is enabling novel possibilities for understanding and supporting various aspects of human-centered applications notably in psychological health and well-being. This talk will highlight some of the advances, opportunities and challenges in gathering human-focused data and creating algorithms for machine processing of such cues. It will report efforts in Behavioral Signal Processing (BSP)—technology and algorithms for quantitatively and objectively understanding typical, atypical and distressed human behavior—with a specific focus on communicative, affective and social behavior. Examples will be drawn from health and wellbeing realms such as Autism Spectrum Disorder, Couple therapy, Depression, Suicidality, and work place behavior. It will also discuss the challenges and opportunities in creating trustworthy signal processing and machine learning approaches that are inclusive, equitable, robust, safe and secure e.g., with respect to protected variables such as gender/race/age/ability etc.

Title: Data Augmentation Based Backdoor for Poisoning and Watermarking of Deep Neural Networks

Abstract:  The decision boundaries of lower bias complex deep neural network (DNN) are more easily overstrained by source distribution of the training dataset to perform poorly on domain shift. By increasing the size and diversity of the training dataset, data augmentation can reduce the variance of complex model to overcome the overfitting problem and increase its generalization capability. This talk will present two atypical and contrary uses of data augmentation on DNNs. While the global market capitalization of artificial intelligence (AI) product has risen tremendously in recent years, deployment of pre-trained DNN models continues to be threatened by the notorious backdoor attacks. The first part of this talk will demonstrate that a data augmentation based backdoor attack can achieve higher stealth, attack success rate, and robustness against state-of-the-art backdoor detectors. As the payoff of a well-trained proprietary DNN model is an outcome of heaving investment in computing power and labour on arduous data collection and labelling tasks, it deserves specific protection and digital rights management. Unfortunately, surrogate attacks and emerging model extraction techniques make it feasible to reverse engineer a deployed DNN model and rebuild an AI product or solution with similar quality at a lower cost than re-designing a DNN from scratch. The rampant DNN IP infringement is further exacerbated by the lack of buyer traceability to deter dishonest users from misappropriation of distributed models. The pirated model may undergo post-processing or transfer learning to fit into the attacker’s use cases to evade IP detection. To deal with this problem, a new backdoor based buyer-traceable watermarking scheme against model piracy and misappropriation will be presented in the second part of this talk.
