In multi-event survival analysis, one aims to predict the probability of multiple different events occurring over some time horizon. One typically assumes that the timing of events is drawn from some distribution conditioned on an individual's covariates. However, during training, one does not have access to this distr...

Plug-and-Play Domain Adaptation for Cross-Subject EEG-based Emotion Recognition
https://ojs.aaai.org/index.php/AAAI/article/view/16169
https://ojs.aaai.org/index.php/AAAI/article/download/16169/15976
[ "Li-Ming Zhao", "Xu Yan", "Bao-Liang Lu" ]
Human emotion decoding in affective brain-computer interfaces suffers a major setback due to the inter-subject variability of electroencephalography (EEG) signals. Existing approaches usually require amassing extensive EEG data of each new subject, which is prohibitively time-consuming along with poor user experience. ...

Probabilistic Programming Bots in Intuitive Physics Game Play
https://ojs.aaai.org/index.php/AAAI/article/view/16159
https://ojs.aaai.org/index.php/AAAI/article/download/16159/15966
[ "Fahad Alhasoun", "Sarah Alneghiemish" ]
Recent findings suggest that humans deploy cognitive mechanism of physics simulation engines to simulate the physics of objects. We propose a framework for bots to deploy probabilistic programming tools for interacting with intuitive physics environments. The framework employs a physics simulation in a probabilistic wa...

Model-Agnostic Fits for Understanding Information Seeking Patterns in Humans
https://ojs.aaai.org/index.php/AAAI/article/view/16160
https://ojs.aaai.org/index.php/AAAI/article/download/16160/15967
[ "Soumya Chatterjee", "Pradeep Shenoy" ]
In decision making tasks under uncertainty, humans display characteristic biases in seeking, integrating, and acting upon information relevant to the task. Here, we reexamine data from previous carefully designed experiments, collected at scale, that measured and catalogued these biases in aggregate form. We design dee...

Apparently Irrational Choice as Optimal Sequential Decision Making
https://ojs.aaai.org/index.php/AAAI/article/view/16161
https://ojs.aaai.org/index.php/AAAI/article/download/16161/15968
[ "Haiyang Chen", "Hyung Jin Chang", "Andrew Howes" ]
In this paper, we propose a normative approach to modeling apparently human irrational decision making (cognitive biases) that makes use of inherently rational computational mechanisms. We view preferential choice tasks as sequential decision making problems and formulate them as Partially Observable Markov Decision Pr...

Visual Relation Detection using Hybrid Analogical Learning
https://ojs.aaai.org/index.php/AAAI/article/view/16162
https://ojs.aaai.org/index.php/AAAI/article/download/16162/15969
[ "Kezhen Chen", "Ken Forbus" ]
Visual Relation Detection is currently one of the most popular problems for visual understanding. Many deep-learning models are designed for relation detection on images and have achieved impressive results. However, deep-learning models have several serious problems, including poor training-efficiency and lack of unde...

Training Binary Neural Network without Batch Normalization for Image Super-Resolution
https://ojs.aaai.org/index.php/AAAI/article/view/16263
https://ojs.aaai.org/index.php/AAAI/article/download/16263/16070
[ "Xinrui Jiang", "Nannan Wang", "Jingwei Xin", "Keyu Li", "Xi Yang", "Xinbo Gao" ]
Recently, binary neural network (BNN) based super-resolution (SR) methods have enjoyed initial success in the SR field. However, there is a noticeable performance gap between the binarized model and the full-precision one. Furthermore, the batch normalization (BN) in binary SR networks introduces floating-point calcula...
