Spike-time encoding of gas concentrations using neuromorphic analog sensory front-end

no code implementations11 Oct 2023 Shavika Rastogi, Nik Dennler, Michael Schmuker, André van Schaik

We show that in the setting of controlled airflow-embedded gas injections, the time difference between the two generated pulses varies inversely with gas concentration, which is in agreement with the spike timing difference between tufted cells and mitral cells of the mammalian olfactory bulb.

Limitations in odour recognition and generalisation in a neuromorphic olfactory circuit

1 code implementation20 Sep 2023 Nik Dennler, André van Schaik, Michael Schmuker

Neuromorphic computing is one of the few current approaches that have the potential to significantly reduce power consumption in Machine Learning and Artificial Intelligence.

Drift in a Popular Metal Oxide Sensor Dataset Reveals Limitations for Gas Classification Benchmarks

no code implementations19 Aug 2021 Nik Dennler, Shavika Rastogi, Jordi Fonollosa, André van Schaik, Michael Schmuker

Metal oxide (MOx) electro-chemical gas sensors are a sensible choice for many applications, due to their tunable sensitivity, their space-efficiency and their low price.

Online Detection of Vibration Anomalies Using Balanced Spiking Neural Networks

no code implementations1 Jun 2021 Nik Dennler, Germain Haessig, Matteo Cartiglia, Giacomo Indiveri

Vibration patterns yield valuable information about the health state of a running machine, which is commonly exploited in predictive maintenance tasks for large industrial systems.

Learning-based Defect Recognition for Quasi-Periodic Microscope Images

1 code implementation2 Jul 2020 Nik Dennler, Antonio Foncubierta-Rodriguez, Titus Neupert, Marilyne Sousa

Controlling crystalline material defects is crucial, as they affect properties of the material that may be detrimental or beneficial for the final performance of a device.
