Not true. ACcording to Treeb's photon theory, photons split into two

Re: Does this imply that lim x --> oo f'(x) = 0?

2013-05-24T05:21:45Z

I think so; use the MVThm repeatedly. Starting in [0,1]:

f(1)-f(0)=f'(c1)*1 , for c in (0,1)

f(2)-f(1)=f'(c2)*1 ; c in (1,2)

...........

f(n+1)-f(n)=f'(cn)*1

_______________________

Now, if f approaches a finite limit at oo , then , as n-->oo f(n+1)-f(n) =f'(cn) -->0 .

Finding paths in trees from Random Forests

2013-05-24T03:29:57Z

If you have a set of trees that are produced over a subset of features (Random Forest application in Machine Learning)in order to average their results and classify some x, what techniques could you use to record the paths taken by the trees to understand the decision that was made? Or if that isn't really feasible, what could help you gain insight into what contributed to the classification of some x based on all your trees in your random forest?

Re: Is my open problem about equality of filters difficult?

2013-05-24T02:18:56Z

No, /\emptyset = P(S)

\/emptyset = emptyset. Proof.

If x in \/emptyset, then there's some set A in emptyset with x in A.
But since no set can be in emptyset, that there's some A is emptyset,
is a contradictionn. Since assuming x in \/emptyset leads to a
contradiction, it must be that \/emptyset is empty.

As another example, f(x) = ln(x)*sin(x*x)/x goes to zero and
d(f(x))/dx goes to +/-oo as x goes to +oo, since it is dominated
by ln(x)*cos(x*x).

Something like f(x) = sum_1^infinity arctan(2^n ( x-2^n) )/2^n should

work. f'(x) is a sum of terms like 1/(1 + (2^n x -2^(2n))^2.
f'(2^n)=1 plus some small positive terms. But f'(2^n+2^(n-1)) should
be pretty close to zero.

No this is wrong, we can easily define a membership relation E*

To remedy that, predicates must be typed after formulas defining them

No.

Let d = 70,000,000.

It's not true that for all primes p there is a prime q with
p < q <= p + d.

For example, let p be the largest prime less than (d + 1)! + 2
and let q be the least prime greater than p. Then q > p + d, so
there are no primes in the range p + 1 to p + d inclusive.
