Paper "Multi-source data analysis for bike sharing systems" propose two types of regression models using multi-source data to predict the hourly bike pick-up demand at cluster level: Similarity Weighted K-Nearest-Neighbor (SWK) based regression and Artificial Neural Network (ANN). SWK-based regression models learn the weights of several meteorological factors and/or taxi usage and use the correlation between consecutive time slots to predict the bike pick-up demand.

This paper presents optimization results of the Al6061 surface roughness in turning ultra-precision based on the central composite design method (CCD) and the grey wolf optimization algorithm (GWO). The experimental matrix is built with three independent variables including spindle speed, feed rate and depth of cut. With the experimental data, the roughness regression model is established.

In this study, one analytical procedure was established for simultaneous determination based on UV-Vis spectrometry coupled with several multivariate linear regress solved by Python – an open language programme to quantify three antibiotics, including TET, PGP, and CEX, in laboratoryprepared synthetic and pharmaceutical mixtures. This study also provided a universally analytical procedure for determining the three antibiotics in their pharmaceutical forms without the need for optimization for each analyte.
