Title:
LAPLACIAN EIGENMAPS-BASED DIMENSION REDUCTION AND VISUALIZATION METHOD FOR HIGH-THROUGHPUT CALCIUM SIGNAL
Document Type and Number:
WIPO Patent Application WO/2023/173770
Kind Code:
A1
Abstract:
A Laplacian Eigenmaps-based dimension reduction and visualization method for a high-throughput calcium signal, comprising performing dimension reduction on a high-dimensional calcium signal recorded in neural optical imaging by means of Laplacian Eigenmaps; extracting effective information; and drawing a dynamic image in a low-dimensional space, so that the visual representation of a neural cluster activity mode recorded by a calcium imaging technique is achieved. Compared with a conventional method such as a generalized linear regression model, a high-throughput calcium signal having a larger scale and a lower signal-to-noise ratio can be processed in the present invention, so that the present invention has obvious advantages in the aspects of the processing of a calcium signal of a large-scale neuron cluster and the dynamic visualization of the signal. In the aspects of clustering accuracy and visual graph discrimination, a Laplacian Eigenmaps-based dimension reduction and visualization method for a high-throughput calcium signal is also superior to other dimension reduction methods, and Laplacian Eigenmaps has low calculation complexity, so that the present invention has remarkable advantages in the aspect of time consumption during operation, and can be used for real-time online dimension reduction and visualization processing.
