Weibo data preprocessing. We analyze 1701 fake news of Weibo propagation networks (with 973,391 users) and 492 real news of Weibo propagation networks (with 347,401 users) that spread on Weibo from 2011 to 2016. We choose here large networks with more than 200 tweets. More details are give...
In this study, A novel method of mapping EEG signals to music is proposed to classify sleep stages. A total of 4.752 selected 1-min sleep records extracted from the capsleep database are applied as the statistical population for this assessment. In this process, first, the tempo and scale ...
Preprocessing of sequencing data The raw data obtained by sequencing was filtered by removing the reads with adapters, reads with N (N means that the base information cannot be determined) greater than 10%, and low-quality reads (Qphred <=20 bases account for more than 50% of the entire ...
Roles: data analyst, data scientist Tools: spreadsheets, MLaaS Data preprocessing The purpose of preprocessing is to convert raw data into a form that fits machine learning. Structured and clean data allows a data scientist to get more precise results from an applied machine learning model. The ...
