Reaching Through Latent Space: From Joint Statistics to Path Planning in Manipulation

no code implementations21 Oct 2022 Chia-Man Hung, Shaohong Zhong, Walter Goodwin, Oiwi Parker Jones, Martin Engelcke, Ioannis Havoutis, Ingmar Posner

We present a novel approach to path planning for robotic manipulators, in which paths are produced via iterative optimisation in the latent space of a generative model of robot poses.

Composing RNNs and FSTs for Small Data: Recovering Missing Characters in Old Hawaiian Text

no code implementations24 Jul 2022 Oiwi Parker Jones, Brendan Shillingford

In contrast to the older writing system of the 19th century, modern Hawaiian orthography employs characters for long vowels and glottal stops.

ObPose: Leveraging Pose for Object-Centric Scene Inference in 3D

no code implementations7 Jun 2022 Yizhe Wu, Oiwi Parker Jones, Ingmar Posner

We present ObPose, an unsupervised object-centric inference and generation model which learns 3D-structured latent representations from RGB-D scenes.

Group-level Brain Decoding with Deep Learning

1 code implementation27 May 2022 Richard Csaky, Mats Van Es, Oiwi Parker Jones, Mark Woolrich

Importantly, group models outperform subject models on low-accuracy subjects (although slightly impair high-accuracy subjects) and can be helpful for initialising subject models.

Next Steps: Learning a Disentangled Gait Representation for Versatile Quadruped Locomotion

no code implementations9 Dec 2021 Alexander L. Mitchell, Wolfgang Merkt, Mathieu Geisert, Siddhant Gangapurwala, Martin Engelcke, Oiwi Parker Jones, Ioannis Havoutis, Ingmar Posner

This encourages disentanglement such that application of a drive signal to a single dimension of the latent state induces holistic plans synthesising a continuous variety of trot styles.

GENESIS-V2: Inferring Unordered Object Representations without Iterative Refinement

1 code implementation NeurIPS 2021 Martin Engelcke, Oiwi Parker Jones, Ingmar Posner

Moreover, object representations are often inferred using RNNs which do not scale well to large images or iterative refinement which avoids imposing an unnatural ordering on objects in an image but requires the a priori initialisation of a fixed number of object representations.

There and Back Again: Learning to Simulate Radar Data for Real-World Applications

no code implementations29 Nov 2020 Rob Weston, Oiwi Parker Jones, Ingmar Posner

Here we propose to learn a radar sensor model capable of synthesising faithful radar observations based on simulated elevation maps.

Reconstruction Bottlenecks in Object-Centric Generative Models

1 code implementation13 Jul 2020 Martin Engelcke, Oiwi Parker Jones, Ingmar Posner

A range of methods with suitable inductive biases exist to learn interpretable object-centric representations of images without supervision.

Improving End-to-End Object Tracking Using Relational Reasoning

no code implementations ICLR 2020 Fabian B. Fuchs, Adam R. Kosiorek, Li Sun, Oiwi Parker Jones, Ingmar Posner

Relational reasoning, the ability to model interactions and relations between objects, is valuable for robust multi-object tracking and pivotal for trajectory prediction.

Imagine That! Leveraging Emergent Affordances for 3D Tool Synthesis

no code implementations30 Sep 2019 Yizhe Wu, Sudhanshu Kasewa, Oliver Groth, Sasha Salter, Li Sun, Oiwi Parker Jones, Ingmar Posner

In this paper we explore the richness of information captured by the latent space of a vision-based generative model.

Imagine That! Leveraging Emergent Affordances for Tool Synthesis in Reaching Tasks

no code implementations25 Sep 2019 Yizhe Wu, Sudhanshu Kasewa, Oliver Groth, Sasha Salter, Li Sun, Oiwi Parker Jones, Ingmar Posner

In this paper we investigate an artificial agent's ability to perform task-focused tool synthesis via imagination.
