Computer scientists ususally are supposed to be good in mathematics but that seems not to be the case these days, we see math in the papers and then we want to avoid it as much as possible :) although i am writing this too I do the same :) even though i like math
A genuine effor now to understand the mathematics behind the papers. I started off the day with reading about the paper of data acquisition in sensor networks...
Basic Math behind the paper
Random Variable: A function that maps events to numbers, sounds cool ...
Recording all these probabilities of output ranges of a real-valued random variable X yields the probability distribution of X.
I seem to be get these things but somehow somethings seems to lag :) ,
for more references
More on this later ...
A very important class of staistical distributions , bell shaped density functions with a single curve. Speaking of it mathematically it needs two quantities which are two quantities have to be specified: the mean , where the peak of the density occurs, and the standard deviation , which indicates the spread or girth of the bell curve
Standard deviation determines the shape of the curve , mean determines the shift of the curve.
