Nearest

 Been playing with the firt assignment on the Learning lecture, CS50 AI.

Found someone who had successfully completed the empty functions and ran

the code. There is a huge - 12,000 records - of visits to a shopping site as data

for the assignment. One opens it in Excel or some such, to peruse the data.

Below, I am on the free Google spreadsheet.

The code uses the Nearest-Neighbor algorithm to predict whether a shopper will

make a purchase or not. The last column in the data records whether a purchase was 

made last time.

All in all, good at predicting a purchase will not be made, but less so about when one

will.

Need to read up more on what is going on. Why I am getting slightly different results

with every run!?
