EACL 20232023End-to-end neural models for conversational AI often assume that a response can be generated by considering only the knowledge acquired by the model during training. Document-oriented conversational models make a similar assumption by conditioning the input on the document and assuming that any other knowledge is captured in the model’s weights. However, a conversation may refer to external knowledge sources

AISTATS 20232023We revisit the problem of fair principal component analysis (PCA), where the goal is to learn the best low-rank linear approximation of the data that obfuscates demographic information. We propose a conceptually simple approach that allows for an analytic solution similar to standard PCA and can be kernelized. Our methods have the same complexity as standard PCA, or kernel PCA, and run much faster than

AAAI 2023 Spring Symposium Series2023This paper describes the development of algorithms that decide when to move, where to move, and how to look for people in a home environment. We introduce a design framework that defines the design principles, key decision points, and technical approaches for a social robot to proactively be with people for companionship and assistance in the home. Through a series of evaluations ranging from simulations

ICRA 20232023This paper introduces a deep learning (DL) approach to predicting congestion delays in large multi-robot systems. The problem is motivated by real-world problems in modern logistics automation, such as a warehouse with hundreds to thousands of coordinated mobile robots. Here, the large scale, the complexity of the control software, and the uncertainties of the robots’ dynamics make direct (simulated) prediction

ICASSP 20232023In this study, we present an approach to train a single speech enhancement network that can perform both personalized and nonpersonalized speech enhancement. This is achieved by incorporating a frame-wise conditioning input that specifies the type of enhancement output. To improve the quality of the enhanced output and mitigate oversuppression, we experiment with re-weighting frames by the presence or absence
