When Does Unsupervised Learning Succeed or Fail? A PoS Perspective on Reconstruction-Based Anomaly Detection
Mehmet Yamaç, Yagmur Mustu, Muhammad Numan Yousaf +2
Reconstruction-based unsupervised learning can fail in two opposing ways: a model may reconstruct anomalies too accurately or discard valid nominal variation. Using the Pursuit of…
EquiSELD: Efficient training of equivariant sound event localization and detection networks
Goksenin Yuksel, Marcel van Gerven, Kiki van der Heijden
First-order Ambisonics (FOA) signals exhibit exact O(3) symmetry: The rotation or reflection of the FOA signal modifies the direction of arrival of the sound sources, while preserv…
Bearings: Self-Supervised Soundfield Embeddings from First-Order Ambisonics
Goksenin Yuksel, Marcel van Gerven, Kiki van der Heijden
Recently proposed self-supervised audio encoders learn powerful general-purpose representations of sound scenes, yet they are spatially blind. To supply the missing spatial represe…
Feasibility of Time-Domain DNN-Based Speech Enhancement on Embedded FPGA for Hearing Aids
Feyisayo Olalere, Umut Altin, Kiki van der Heijden +1
Hearing aids impose strict latency and power constraints that current DNN-based speech enhancement systems struggle to meet on embedded hardware. We characterize this gap by deploy…
Tuning Agent-Based Predator-Prey Models Toward Lotka-Volterra Dynamics
Corinna Mandl, Siddharth Chaturvedi, Marcel van Gerven
Recent growth in compute power has made it increasingly feasible to use large-scale agent-based models to simulate complex adaptive systems. A central difficulty is that such model…
Axiomatizing Neural Networks via Pursuit of Subspaces
Mehmet Yamac, Mert Duman, Ugur Akpinar +4
While deep neural networks have achieved remarkable success across a wide range of domains, their underlying mechanisms remain poorly understood, and they are often regarded as bla…
Hidden States as Value Gradients: The Pontryagin Structure of Recurrent Policies
David Leeftink, Max Hinne, Marcel van Gerven
A key capability of intelligent agents is to act effectively under incomplete state observations. Recurrent policies address this by compressing observation histories into a hidden…
Role Differentiation in a Coupled Resource Ecology under Multi-Level Selection
Siddharth Chaturvedi, Ahmed El-Gazzar, Marcel van Gerven
A group of non-cooperating agents can succumb to the \emph{tragedy-of-the-commons} if all of them seek to maximize the same resource channel to improve their viability. In nature,…
