ReCoRe: Regularized Contrastive Representation Learning of World Model

no code implementations14 Dec 2023 Rudra P. K. Poudel, Harit Pandya, Stephan Liwicki, Roberto Cipolla

To address these challenges, we present a world model that learns invariant features using (i) contrastive unsupervised learning and (ii) an intervention-invariant regularizer.

LanGWM: Language Grounded World Model

no code implementations29 Nov 2023 Rudra P. K. Poudel, Harit Pandya, Chao Zhang, Roberto Cipolla

Furthermore, our proposed technique of explicit language-grounded visual representation learning has the potential to improve models for human-robot interaction because our extracted visual features are language grounded.

Contrastive Unsupervised Learning of World Model with Invariant Causal Features

no code implementations29 Sep 2022 Rudra P. K. Poudel, Harit Pandya, Roberto Cipolla

In particular, we use contrastive unsupervised learning to learn the invariant causal features, which enforces invariance across augmentations of irrelevant parts or styles of the observation.

A Stochastic Bundle Method for Interpolating Networks

1 code implementation29 Jan 2022 Alasdair Paren, Leonard Berrada, Rudra P. K. Poudel, M. Pawan Kumar

We propose a novel method for training deep neural networks that are capable of interpolation, that is, driving the empirical loss to zero.

Recurrent Fully Convolutional Neural Networks for Multi-slice MRI Cardiac Segmentation

no code implementations13 Aug 2016 Rudra P. K. Poudel, Pablo Lamata, Giovanni Montana

In cardiac magnetic resonance imaging, fully-automatic segmentation of the heart enables precise structural and functional measurements to be taken, e. g. from short-axis MR images of the left-ventricle.
