NVIDIA NeMo Offline Speech Translation Systems for IWSLT 2022

no code implementations IWSLT (ACL) 2022 Oleksii Hrinchuk, Vahid Noroozi, Ashwinkumar Ganesan, Sarah Campbell, Sandeep Subramanian, Somshubra Majumdar, Oleksii Kuchaiev

Our cascade system consists of 1) Conformer RNN-T automatic speech recognition model, 2) punctuation-capitalization model based on pre-trained T5 encoder, 3) ensemble of Transformer neural machine translation models fine-tuned on TED talks.

Learning with Holographic Reduced Representations

1 code implementation NeurIPS 2021 Ashwinkumar Ganesan, Hang Gao, Sunil Gandhi, Edward Raff, Tim Oates, James Holt, Mark McLean

HRRs today are not effective in a differentiable solution due to numerical instability, a problem we solve by introducing a projection step that forces the vectors to exist in a well behaved point in space.

Learning a Reversible Embedding Mapping using Bi-Directional Manifold Alignment

no code implementations Findings (ACL) 2021 Ashwinkumar Ganesan, Francis Ferraro, Tim Oates

We propose a Bi-Directional Manifold Alignment (BDMA) that learns a non-linear mapping between two manifolds by explicitly training it to be bijective.

Locality Preserving Loss: Neighbors that Live together, Align together

no code implementations EACL (AdaptNLP) 2021 Ashwinkumar Ganesan, Francis Ferraro, Tim Oates

We present a locality preserving loss (LPL) that improves the alignment between vector space embeddings while separating uncorrelated representations.

Determining the Scale of Impact from Denial-of-Service Attacks in Real Time Using Twitter

no code implementations12 Sep 2019 Chi Zhang, Bryan Wilkinson, Ashwinkumar Ganesan, Tim Oates

Another way to remove that limitation, an optional classification layer, trained on manually annotated DoS attack tweets, to filter out non-attack tweets can be used to increase precision at the expense of recall.

Extending Signature-based Intrusion Detection Systems WithBayesian Abductive Reasoning

no code implementations28 Mar 2019 Ashwinkumar Ganesan, Pooja Parameshwarappa, Akshay Peshave, ZhiYuan Chen, Tim Oates

In this paper, we proposeaprobabilistic abductive reasoningapproach that augments an exist-ing rule-based IDS (snort [29]) to detect these evolved attacks by (a)Predicting rule conditions that are likely to occur (based on existingrules) and (b) able to generate new snort rules when provided withseed rule (i. e. a starting rule) to reduce the burden on experts toconstantly update them.

Fashioning with Networks: Neural Style Transfer to Design Clothes

no code implementations31 Jul 2017 Prutha Date, Ashwinkumar Ganesan, Tim Oates

Convolutional Neural Networks have been highly successful in performing a host of computer vision tasks such as object recognition, object detection, image segmentation and texture synthesis.

Identifying Spatial Relations in Images using Convolutional Neural Networks

no code implementations13 Jun 2017 Mandar Haldekar, Ashwinkumar Ganesan, Tim Oates

Traditional approaches to building a large scale knowledge graph have usually relied on extracting information (entities, their properties, and relations between them) from unstructured text (e. g. Dbpedia).
