Suppose we want to check how to map the real points into this RBF corner.

Okay we are given five original points like this.

X sub 1, X sub 2, X sub 3 to X sub 5.

For these five points this is original space.

If we set sigma equals to 4 actually you can set sigma to

other values as well, okay.

Equals to 4, the calculation just a little nicer and simpler.

So you probably can see then if we want to calculate this distance,

okay, this formula, this formula that is on the top of this part.

What we can see is x1 is zero zero, so

there are two zeroes, and x two, x is four four, these two fours.

So when you compute this distance you basically compute the sum of their square

distance, equals 32, then based on these formulas or

we get a e to the power minus 32 divide by 2.

Times 4 square, then you get to without a e, to the power of minus 1.
