Diving in Covariance and Variance from an idea of building a Virtual Teaching Assistant
I have ideas and sometimes those ideas with limited knowledge supports. In order to make something happen. My advisor, Yue recommend me to learn "Covariance and Variance". Yue threw me a question like below. He asked X is n by n matrix, what Y is.
I have no concept what the symbol X with a bar on the top and what the X' represents!!!
So, I start my journey to learn standard deviation...
Standard Deviation: mathematical symbols [sigma] 𝝈
If I cannot apply this function or concept to approach to my idea, I may never can understand and remember it at all. Since I need to predict "students intent", I need to figure out the students speech and intent? To what extent a specific "word" relate a clean "intent"? How to calculate it? with I should say I need to better understand how computer predict students practical intentions.
Here I found a video. I like the design and animation. Here you go:
The intuition tells me those concept will help...
