Suppose we want to assign points to one of two cluster centroids, either (0,0) or (100,40). depending on whether we use the l1 or l2 norm, a point (x, y) could be clustered with a different one of these two centroids. for this problem, you should work out the conditions under which a point will be clustered with the centoid (0,0) when the l1 norm is used, but clustered with the centroid (100,40) when the l2 norm is used.

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.

There is a paper clip on the bottom left side below the question box 

Why can you not find anything better to do i mean i guess talking to strangers is pretty entertaining
