Confusion of Tagged Perturbations in Forward Automatic Differentiation of Higher-Order Functions
Oleksandr Manzyuk, Barak A. Pearlmutter, Alexey Andreyevich Radul +2
Forward Automatic Differentiation (AD) is a technique for augmenting programs to compute derivatives. The essence of Forward AD is to attach perturbations to each number, and propa…
Large-Scale Automatic Labeling of Video Events with Verbs Based on Event-Participant Interaction
Andrei Barbu, Alexander Bridge, Dan Coroian +12
We present an approach to labeling short video clips with English verbs as event descriptions. A key distinguishing aspect of this work is that it labels videos with verbs that des…
Seeing Unseeability to See the Unseeable
Siddharth Narayanaswamy, Andrei Barbu, Jeffrey Mark Siskind
We present a framework that allows an observer to determine occluded portions of a structure by finding the maximum-likelihood estimate of those occluded portions consistent with v…
Video In Sentences Out
Andrei Barbu, Alexander Bridge, Zachary Burchill +15
We present a system that produces sentential descriptions of video: who did what to whom, and where and how they did it. Action class is rendered as a verb, participant objects as…
Simultaneous Object Detection, Tracking, and Event Recognition
Andrei Barbu, Aaron Michaux, Siddharth Narayanaswamy +1
The common internal structure and algorithmic organization of object detection, detection-based tracking, and event recognition facilitates a general approach to integrating these…
AD in Fortran, Part 2: Implementation via Prepreprocessor
Alexey Radul, Barak A. Pearlmutter, Jeffrey Mark Siskind
We describe an implementation of the Farfel Fortran AD extensions. These extensions integrate forward and reverse AD directly into the programming model, with attendant benefits to…
