To sort or not to sort: the impact of spike-sorting on neural decoding performance

To sort or not to sort: the impact of spike-sorting on neural decoding performance.

OBJECTIVE Brain-computer interfaces (BCIs) are a promising technology for restoring motor ability to paralyzed patients. Spiking-based BCIs have successfully been used in clinical trials to control multi-degree-of-freedom robotic devices. Current implementations of these devices require a lengthy spike-sorting step, which is an obstacle to moving this technology from the lab to the clinic. A vi...

The Effect of Local Sort on Parallel Sorting Algorithms

We show the importance of sequential sorting in the context of in memory parallel sorting of large data sets of 64 bit keys. First, we analyze several sequential strategies like Straight Insertion, Quick sort, Radix sort and CC-Radix sort. As a consequence of the analysis, we propose a new algorithm that we call Sequential Counting Split Radix sort, SCS-Radix sort. SCS-Radix sort is a combinati...

Performance Analysis of Merge Sort and Quick Sort: MQSORT

Sorting is considered as a fundamental operation in computer science as it is used as an intermediate step in many operations. Sorting refers to the operation of arranging data in some given order such as increasing or decreasing, with numerical data, or alphabetically, with character data. An algorithm is any well-defined procedure or set of instructions, that takes some input in the form of s...

Performance / Price Sort

NTsort is an external sort on WindowsNT 5.0. It has minimal functionality but excellent price performance. In particular, running on mail-order hardware it can sort 1.5 GB for a penny. NT5.0 is not yet available. For commercially available sorts, Postman Sort from Robert Ramey Software Development has elapsed time performance comparable to NTsort, while using less processor time. It can sort 1....
