Please describe the relationship between bias, variance, underfitting, and overfitting. Support your answers with examples if needed.
Pick and summarise ONE (1) article that uses data classification in a variety of domains. (The summary should concentrate on how the material applies to data classification analysis specifically.) Please respond to the following questions:
i. What is the problem or question(s) that this study is addressing? You should be able to locate the focal point. If there are any other issues, make a note of them as well. ii. What is the data's source? There are two or more sources of data in some studies. Give a brief description of how the data was obtained.
You must present an examination of "Population & Housing in San Diego County." The goal is to look for correlations between the shifting population and residential unit density in the county. How would you go about conducting this inquiry? Please specify which data files are needed and where they might be found (including any relevant references). Which data model will you use to conduct this investigation? (You do not need to finish the analysis but you may examine the data files on the web).
