Arbitrage-free pricing of CVA for cross-currency swap with wrong-way risk under stochastic correlation modeling framework

no code implementations13 Jul 2021 Ashish Kumar, Laszlo Markus, Norbert Hari

This effect is reflected in the results where the impact of stochastic correlation on calculated CVA is substantial when compared to the case when a high constant correlation is assumed between exposure and credit.

RMA: Rapid Motor Adaptation for Legged Robots

no code implementations8 Jul 2021 Ashish Kumar, Zipeng Fu, Deepak Pathak, Jitendra Malik

Successful real-world deployment of legged robots would require them to adapt in real-time to unseen scenarios like changing terrains, changing payloads, wear and tear.

Shape Back-Projection In 3D Scenes

no code implementations16 Jan 2021 Ashish Kumar, L. Behera

In the overall process, first, shape histogram of a sample surface (e. g. planar) is computed, which captures the profile of surface normals around a point in form of a probability distribution.

DeepMI: A Mutual Information Based Framework For Unsupervised Deep Learning of Tasks

no code implementations16 Jan 2021 Ashish Kumar, Laxmidhar Behera

In this work, we propose an information theory based framework DeepMI to train deep neural networks (DNN) using Mutual Information (MI).

Towards Deep Learning Assisted Autonomous UAVs for Manipulation Tasks in GPS-Denied Environments

no code implementations16 Jan 2021 Ashish Kumar, Mohit Vohra, Ravi Prakash, L. Behera

In this work, we present a pragmatic approach to enable unmanned aerial vehicle (UAVs) to autonomously perform highly complicated tasks of object pick and place.

MACE: Model Agnostic Concept Extractor for Explaining Image Classification Networks

1 code implementation3 Nov 2020 Ashish Kumar, Karan Sehgal, Prerna Garg, Vidhya Kamakshi, Narayanan C Krishnan

The current methods to explain the predictions of a pre-trained model rely on gradient information, often resulting in saliency maps that focus on the foreground object as a whole.

Domain Independent Unsupervised Learning to grasp the Novel Objects

no code implementations9 Jan 2020 Siddhartha Vibhu Pharswan, Mohit Vohra, Ashish Kumar, Laxmidhar Behera

In this paper, we present a novel unsupervised learning based algorithm for the selection of feasible grasp regions.

Learning Navigation Subroutines from Egocentric Videos

no code implementations29 May 2019 Ashish Kumar, Saurabh Gupta, Jitendra Malik

We demonstrate our proposed approach in context of navigation, and show that we can successfully learn consistent and diverse visuomotor subroutines from passive egocentric videos.

FastGRNN: A Fast, Accurate, Stable and Tiny Kilobyte Sized Gated Recurrent Neural Network

1 code implementation NeurIPS 2018 Aditya Kusupati, Manish Singh, Kush Bhatia, Ashish Kumar, Prateek Jain, Manik Varma

FastRNN addresses these limitations by adding a residual connection that does not constrain the range of the singular values explicitly and has only two extra scalar parameters.

Visual Memory for Robust Path Following

no code implementations NeurIPS 2018 Ashish Kumar, Saurabh Gupta, David Fouhey, Sergey Levine, Jitendra Malik

Equipped with this abstraction, a second network observes the world and decides how to act to retrace the path under noisy actuation and a changing environment.

Resource-efficient Machine Learning in 2 KB RAM for the Internet of Things

1 code implementation ICML 2017 Ashish Kumar, Saurabh Goyal, Manik Varma

This paper develops a novel tree-based algorithm, called Bonsai, for efficient prediction on IoT devices – such as those based on the Arduino Uno board having an 8 bit ATmega328P microcontroller operating at 16 MHz with no native floating point support, 2 KB RAM and 32 KB read-only flash.
