How do you measure similarity?
To calculate the similarity between two examples, you need to combine all the feature data for those two examples into a single numeric value. For instance, consider a shoe data set with only one feature: shoe size. You can quantify how similar two shoes are by calculating the difference between their sizes.
How do you find the similarity between two time series?
Any two time series can be compared using euclidean distance or other similar distances on a one to one basis on time axis. The amplitude of first time series at time T will be compared with amplitude of second time series at time T.
How do you find statistical similarity?
We measure the statistical similarity between pair variables by evaluating their probability distributions. It's always easy to first plot a histogram or bar plot to see whether the shape of two plots are similar.
