A Potential Spike Sorting Algorithm
This is a short summary of the work I did for 6 weeks as a summer intern with Conor Houghton. The topic of the internship was spike sorting, in particular to test an algorithm suggested by Dr.Houghton. I’ll first briefly describe spike sorting, at least my understanding of it. A few small biological details (which I’m sure are a simplification) a neuron fires ‘spikes’ of voltages; different typ...

The use of distributed generation units in distribution networks has attracted the attention of network managers due to its great benefits. In this research, the location and determination of the capacity of distributed generation (DG) units for different purposes has been studied simultaneously. The multi-objective functions in the optimization model are reducing system line losses; reducing v...
متن کاملA Brief Look into Spike Sorting Methods
Spike sorting is a class of techniques used in the analysis of electrophysiological data. Studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. This article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.
