When it comes to teaching mathematics to children, there exist a number of schools of thoughts on what the ideal curriculum ought to be.
There are the conventional models of teaching math, there are harder theory based models and there are the more interesting practical hands-on models.

The authors present the multivariate spectral gradient (MSG) method for solving unconstrained optimization problems. Combined with some quasi-Newton property the MSG method allows an individ... | {"url":"http://zbmath.org/?q=an:1155.65046","timestamp":"2014-04-18T13:18:27Z","content_type":null,"content_length":"22334","record_id":"<urn:uuid:6169fc91-2f54-451e-a662-21ec0c2a2e19>","cc-path":"CC-MAIN-2014-15/segments/1398223203841.5/warc/CC-MAIN-20140423032003-00047-ip-10-147-4-33.ec2.internal.warc.gz"} |
Mean squared normalized error performance function
mse is a network performance function. It measures the network's performance according to the mean of squared errors.
perf = mse(net,t,y,ew) takes these arguments:
net Neural network
t Matrix or cell array of targets
y Matrix or cell array of outputs

Permutations and Combinations Help!

More on Diff. Forms and Distributions as Kernels
Hi, Again:
I'm trying to show that, given a 3-manifold M, and a plane field ρ (i.e., a distribution on
TM) on M, there exists an open set U in M, so that ρ can be represented as the kernel of a
differential form w , for W defined on U.
The idea is that the kernel of a li... | {"url":"http://www.physicsforums.com/showthread.php?p=4155856","timestamp":"2014-04-21T09:51:47Z","content_type":null,"content_length":"56499","record_id":"<urn:uuid:4efc95ea-59d8-4d7f-9c99-99dfecb10e9a>","cc-path":"CC-MAIN-2014-15/segments/1397609539705.42/warc/CC-MAIN-20140416005219-00348-ip-10-147-4-33.ec2.internal.... |
