Learning Object Permanence from Videos via Latent Imaginations

no code implementations16 Oct 2023 Manuel Traub, Frederic Becker, Sebastian Otte, Martin V. Butz

While human infants exhibit knowledge about object permanence from two months of age onwards, deep-learning approaches still largely fail to recognize objects' continued existence.

Loci-Segmented: Improving Scene Segmentation Learning

1 code implementation16 Oct 2023 Manuel Traub, Frederic Becker, Adrian Sauter, Sebastian Otte, Martin V. Butz

Current slot-oriented approaches for compositional scene segmentation from images and videos rely on provided background information or slot assignments.

The Deep Arbitrary Polynomial Chaos Neural Network or how Deep Artificial Neural Networks could benefit from Data-Driven Homogeneous Chaos Theory

no code implementations26 Jun 2023 Sergey Oladyshkin, Timothy Praditia, Ilja Kröker, Farid Mohammadi, Wolfgang Nowak, Sebastian Otte

However, for a majority of deep learning approaches based on DANNs, the kernel structure of neural signal processing remains the same, where the node response is encoded as a linear superposition of neural activity, while the non-linearity is triggered by the activation functions.

Efficient LSTM Training with Eligibility Traces

no code implementations30 Sep 2022 Michael Hoyer, Shahram Eivazi, Sebastian Otte

With the help of these extensions we show that, under certain conditions, e-prop can outperform BPTT for one of the two benchmarks for supervised learning.

Binding Dancers Into Attractors

no code implementations1 Jun 2022 Franziska Kaltenberger, Sebastian Otte, Martin V. Butz

Our system flexibly binds the information of the rotating figure into the alternative attractors resolving the illusion's ambiguity and imagining the respective depth interpretation and the corresponding direction of rotation.
