Introduction to Principal Component Analysis


This is the Part 35 of the Lecture. For the complete lecture on PCA click here.


Principal Component Analysis (PCA) is a statistical technique commonly used in data analysis to simplify the complexity of large datasets by transforming the original variables into a smaller set of uncorrelated variables known as principal components. These components capture the maximum amount of variance in the data, thereby allowing for easier interpretation and visualization of the underlying patterns and relationships. PCA is widely used in fields such as machine learning, image processing, and genetics, providing researchers with valuable insights and actionable information for decision-making. By identifying the key dimensions driving variation in the data, PCA enables researchers to better understand and extract meaningful information from complex datasets.

Retention Change Indicator

Watershed retain water from rainfall within its soil pores and depressions available in the basin. If this capacity of retention get receeded there will be stress on the supply of both water and food to dependent consumers. Check, whether the watershed on which you are staying maintains a healthy retention capacity ? A new tool will help you to ascertain the same and make you prepared for the uncertainties that may come if the retention capacity of your watershed has changed negatively. Get the tool from www.baipatra.ws Thanks, Mrinmoy
