This study investigates unsupervised novelty detection (ND) for screening of rare myopathies and specifically myositis. To support this study we developed from the ground up a novel and fully annotated dataset consisting of 3586 images taken of eighty nine individuals obtained under informed consent during 2016-2017. We developed and compared perfo   ...more

Prospection is key to solving challenging problems in new environments, but it has not been deeply explored as applied to task planning for perception-driven robotics. We propose visual robot task planning, where we take in an input image and must generate a sequence of high-level actions and associated observations that achieve some task. In this   ...more

Recent technological developments, such as high-throughput imaging and sequencing, enable experimentalists to collect increasingly large, complex, and heterogeneous ‘big’ data. These studies result in terabytes of data per day, yielding petabytes across experiments and laboratories. These experimental capabilities exceed the scale or feature set of   ...more

We present a generic data-driven method to address the problem of manipulating a three-dimensional (3-D) compliant object (CO) with heterogeneous physical properties in the presence of unknown disturbances. In this study, we do not assume a prior knowledge about the deformation behavior of the CO and type of the disturbance (e.g., internal or exte   ...more

In this paper, we investigate the use of surrogate agents to accelerate test scenario generation for autonomous vehicles. Our goal is to train the surrogate to replicate the true performance modes of the system. We create these surrogates by utilizing imitation learning with deep neural networks. By using imitator surrogates in place of the true a   ...more

In this paper we propose a new method for generating test scenarios for black-box autonomous systems that demonstrate critical transitions in performance modes. This method provides a test engineer with key insights into the software’s decision-making engine and how those decisions affect transitions between performance modes. We achieve this via   ...more
