ABSTRACT:
The fields of neural computation and artificial neural networks have developed much in the last decades. Since technical, physical, and also cognitive processes evolve in time, neural networks should be considered, which allow us to model the synthesis and analysis of continuous and possibly periodic processes in time besides computing discrete classification functions. This work in progress is motivated by different application scenarios: programming robot behavior of autonomous robots and musical harmony perception. In the beginning of the talk, the first application scenario is introduced, namely object recognition with multicopters. Here, the image recognition procedure employs methods from machine learning (clustering and decision trees) and computer vision (image segmentation and contour signatures). After that, the topic of musical harmony perception is introduced, taking recent results from psychophysics and neuroacoustics into account, in particular, that periodicities of complex chords can be detected in the human brain. In the last part of the talk, a continuous-time neural network architecture (without recurrence) is introduced, which is suitable to model the scenarios just mentioned.
