Neural Population Decoding and Imbalanced Multi-Omic Datasets For Cancer Subtype Diagnosis

no code implementations6 Jan 2024 Charles Theodore Kent, Leila Bagheriye, Johan Kwisthout

Recent strides in the field of neural computation has seen the adoption of Winner Take All (WTA) circuits to facilitate the unification of hierarchical Bayesian inference and spiking neural networks as a neurobiologically plausible model of information processing.

Bayesian Inference

Cancer Subtype Identification through Integrating Inter and Intra Dataset Relationships in Multi-Omics Data

1 code implementation2 Dec 2023 Mark Peelen, Leila Bagheriye, Johan Kwisthout

This paper proposes a novel approach to identify cancer subtypes through the integration of multi-omics data for clustering.

Clustering Survival Analysis

Bayesian Integration of Information Using Top-Down Modulated WTA Networks

1 code implementation29 Aug 2023 Otto van der Himst, Leila Bagheriye, Johan Kwisthout

The results show that WTA circuits are capable of integrating the probabilistic information represented by other WTA networks, and that top down processes can improve a WTA network's inference and learning performance.

Benchmarking energy consumption and latency for neuromorphic computing in condensed matter and particle physics

no code implementations21 Sep 2022 Dominique J. Kösters, Bryan A. Kortman, Irem Boybat, Elena Ferro, Sagar Dolas, Roberto de Austri, Johan Kwisthout, Hans Hilgenkamp, Theo Rasing, Heike Riel, Abu Sebastian, Sascha Caron, Johan H. Mentink

The massive use of artificial neural networks (ANNs), increasingly popular in many areas of scientific computing, rapidly increases the energy consumption of modern high-performance computing systems.

Motivating explanations in Bayesian networks using MAP-independence

no code implementations5 Aug 2022 Johan Kwisthout

In decision support systems the motivation and justification of the system's diagnosis or classification is crucial for the acceptance of the system by the human user.

On the computational power and complexity of Spiking Neural Networks

no code implementations23 Jan 2020 Johan Kwisthout, Nils Donselaar

However, to date a comparison with more traditional computational architectures (particularly with respect to energy usage) is hampered by the lack of a formal machine model and a computational complexity theory for neuromorphic computation.

A spiking neural algorithm for the Network Flow problem

no code implementations29 Nov 2019 Abdullahi Ali, Johan Kwisthout

More in specific we show that a logspace-constrained Turing machine with access to an interactive neuromorphic oracle with linear space, time, and energy constraints can solve Max Network Flow.

Finding dissimilar explanations in Bayesian networks: Complexity results

no code implementations26 Oct 2018 Johan Kwisthout

Finding the most probable explanation for observed variables in a Bayesian network is a notoriously intractable problem, particularly if there are hidden variables in the network.
