On the Generation of a Synthetic Event-Based Vision Dataset for Navigation and Landing

1 code implementation1 Aug 2023 Loïc J. Azzalini, Emmanuel Blazquez, Alexander Hadjiivanov, Gabriele Meoni, Dario Izzo

We anticipate that novel event-based vision datasets can be generated using this pipeline to support various spacecraft pose reconstruction problems given events as input, and we hope that the proposed methodology would attract the attention of researchers working at the intersection of neuromorphic vision and guidance navigation and control.

Neuromorphic Computing and Sensing in Space

no code implementations10 Dec 2022 Dario Izzo, Alexander Hadjiivanov, Dominik Dold, Gabriele Meoni, Emmanuel Blazquez

The term ``neuromorphic'' refers to systems that are closely resembling the architecture and/or the dynamics of biological neural networks.

Continuous Learning and Adaptation with Membrane Potential and Activation Threshold Homeostasis

no code implementations22 Apr 2021 Alexander Hadjiivanov

Most classical (non-spiking) neural network models disregard internal neuron dynamics and treat neurons as simple input integrators.

Epigenetic evolution of deep convolutional models

1 code implementation12 Apr 2021 Alexander Hadjiivanov, Alan Blair

In this study, we build upon a previously proposed neuroevolution framework to evolve deep convolutional models.

Adaptive conversion of real-valued input into spike trains

no code implementations12 Apr 2021 Alexander Hadjiivanov

Another merit of the proposed method is that it requires only one input neuron per variable, rather than an entire population of neurons as in the case of the commonly used conversion method based on Gaussian receptive fields.

Complexity-based speciation and genotype representation for neuroevolution

no code implementations11 Oct 2020 Alexander Hadjiivanov, Alan Blair

This paper introduces a speciation principle for neuroevolution where evolving networks are grouped into species based on the number of hidden neurons, which is indicative of the complexity of the search space.
