Based on our empirical study, we find that the performance of portfolio produced using clustering with Ward algorithm is better than portfolio performance produced by the clustering with complete linkage algorithm for all risk aversion values. Besides, we also find that port...

However, with 20 erythroblast cells, the clustering algorithm failed to cluster them separately, with the algorithm instead assigning them to multiple clusters (Monocytes, NK cells, CD4 T cells and CD8 naive cells clusters). Since erythroblast has very distinct cell populations compared to cell ...
The analysis was performed in MATLAB using ‘localcontrast’, ‘edge’ (with Canny algorithm), ‘rmoutliers’ and ‘fit’ functions. The exact parameters for these functions had to be adjusted in a few cases of lower signal-to-noise ratio. To import the images into MATLAB R2018b, we used...
S2b). Unsupervised cell type clustering was performed on the integrated dataset, resulting in ten unique populations, herein referred to as cell communities (Fig. 2a and Supplementary Table S1). The ten communities represent all major brain cell types, including stem- and progenitor-like, glial, ...
The architecture takes as input n x 3 points and finds normals for them which is used for ordering of points. A subsample of points is taken using the FPS algorithm resulting in ni x 3 points. On these annular convolution is applied to increase to 128 dimensions. Annular convolution is pe...
