Object classification from randomized EEG trials

no code implementations CVPR 2021 Hamad Ahmed, Ronnie B Wilbur, Hari M Bharadwaj, Jeffrey Mark Siskind

A prior attempt to avoid this confound using randomized trials was unable to achieve results above chance in a statistically significant fashion when the data sets were of the same size as the original experiments.

Training on the test set? An analysis of Spampinato et al. [arXiv:1609.00344]

no code implementations18 Dec 2018 Ren Li, Jared S. Johansen, Hamad Ahmed, Thomas V. Ilyevsky, Ronnie B Wilbur, Hari M Bharadwaj, Jeffrey Mark Siskind

A recent paper [arXiv:1609. 00344] claims to classify brain processing evoked in subjects watching ImageNet stimuli as measured with EEG and to use a representation derived from this processing to create a novel object classifier.

Binomial Checkpointing for Arbitrary Programs with No User Annotation

no code implementations10 Nov 2016 Jeffrey Mark Siskind, Barak A. Pearlmutter

Heretofore, automatic checkpointing at procedure-call boundaries, to reduce the space complexity of reverse mode, has been provided by systems like Tapenade.

Tricks from Deep Learning

no code implementations10 Nov 2016 Atılım Güneş Baydin, Barak A. Pearlmutter, Jeffrey Mark Siskind

The deep learning community has devised a diverse set of methods to make gradient optimization, using large datasets, of large and highly complex models with deeply cascaded nonlinearities, practical.

DiffSharp: An AD Library for .NET Languages

no code implementations10 Nov 2016 Atılım Güneş Baydin, Barak A. Pearlmutter, Jeffrey Mark Siskind

DiffSharp is an algorithmic differentiation or automatic differentiation (AD) library for the . NET ecosystem, which is targeted by the C# and F# languages, among others.

Robot Language Learning, Generation, and Comprehension

no code implementations25 Aug 2015 Daniel Paul Barrett, Scott Alan Bronikowski, Haonan Yu, Jeffrey Mark Siskind

We present a unified framework which supports grounding natural-language semantics in robotic driving.

Sentence Directed Video Object Codetection

no code implementations5 Jun 2015 Haonan Yu, Jeffrey Mark Siskind

We tackle the problem of video object codetection by leveraging the weak semantic constraint implied by sentences that describe the video content.

A Faster Method for Tracking and Scoring Videos Corresponding to Sentences

no code implementations14 Nov 2014 Haonan Yu, Daniel P. Barrett, Jeffrey Mark Siskind

Prior work presented the sentence tracker, a method for scoring how well a sentence describes a video clip or alternatively how well a video clip depicts a sentence.

Saying What You're Looking For: Linguistics Meets Video Search

no code implementations20 Sep 2013 Andrei Barbu, N. Siddharth, Jeffrey Mark Siskind

We present an approach to searching large video corpora for video clips which depict a natural-language query in the form of a sentence.

Seeing What You're Told: Sentence-Guided Activity Recognition In Video

no code implementations CVPR 2014 N. Siddharth, Andrei Barbu, Jeffrey Mark Siskind

We present a system that demonstrates how the compositional structure of events, in concert with the compositional structure of language, can interplay with the underlying focusing mechanisms in video action recognition, thereby providing a medium, not only for top-down and bottom-up integration, but also for multi-modal integration between vision and language.

Discriminative Training: Learning to Describe Video with Sentences, from Video Described with Sentences

no code implementations21 Jun 2013 Haonan Yu, Jeffrey Mark Siskind

We present a method for learning word meanings from complex and realistic video clips by discriminatively training (DT) positive sentential labels against negative ones, and then use the trained word models to generate sentential descriptions for new video.

Felzenszwalb-Baum-Welch: Event Detection by Changing Appearance

no code implementations20 Jun 2013 Daniel Paul Barrett, Jeffrey Mark Siskind

This method makes it possible to detect events which are characterized not by motion, but by the changing state of the people or objects involved.

Confusion of Tagged Perturbations in Forward Automatic Differentiation of Higher-Order Functions

no code implementations20 Nov 2012 Oleksandr Manzyuk, Barak A. Pearlmutter, Alexey Andreyevich Radul, David R. Rush, Jeffrey Mark Siskind

The essence of Forward AD is to attach perturbations to each number, and propagate these through the computation.
