Re: Next generation name is FB++ ?

Perhaps we can liven things up a bit with a 1.06 release and get everyone on the same footing. <smile>

Re: What is machine learning?

I fed my neural net two million throws of the dice, yet it still couldn't predict the outcome of the next one! That made me laugh. If it was so capable you would be in line for a Nobel Prize. <smile> Talking of Lottery numbers I wrote a lottery program which uses Intel's RdRand. I win, admittedly s...

Re: Machine Learning

In badidea's link from the 15th image onward you will something like df(e)/de, which could be written f'(e). I don't know how far you went with maths but that is differential calculus. In that link the derivatives are coefficients. The larger the derivative the larger the influence. Derivatives clos...

Re: Machine Learning

filter the results of which errors are not smaller than the previous one. That is an iterative process and not a fully fledged learning machine. What if we destroyed the neurons that don't perform well enough? Would it motivate them ? :D Bad idea. You may destroy a neuron which is destined for grea...

Re: Machine Learning

With Newton's method when we overshoot a 'solution' we turn back and reduce the step size. If we do not reduce the step size then we will return whence we came. What we then see is an oscillation about the solution. In your code you have Sleep 40. I changed to Sleep and kept pressing Enter. Now, we ...

Re: Machine Learning

In a way Newton's method could be described as unsupervised learning. It will realise that it has overshot a 'solution' so will turn back on itself and reduce the step size. It will overshoot the solution again, turn back on itself and reduce the step size again. We will get it to report when the st...

Re: Machine Learning

@Tourist Trap Re your corrected code. THIS.inputArray(5)* THIS.inputArray(6) is a constant and analogous to your orignal's code using e*f. 'e' and 'f' can have many values resulting in e*f being the same. I can understand using just 'e' or just 'f' but I cannot understand your use of e*f. Also, 'try...

Re: Machine Learning

[off topic] NO , never , this is exactly , what democracy is all about! I know and I disagree with it. I believe in a 'one person, one vote' parliamentary system where the electorate are given the opportunity to vote for a representative in parliament but not allowed to vote on anything else. Any ot...

Re: Machine Learning

It is how I understand machine learning right now, but I must be wrong since it doesn't work too much. Ha, ha. I am not trying to put you off. If you are finding it fun then stay with it. As some gambling sites say: When the fun stops, stop. I know one thing and that is it is beyond what my old bra...

Re: Machine Learning

Reminds me of the current debate in this country with regards to reducing taxation. There we have the classic example of solving an equation with a couple of variables when, in fact, perhaps eight exist. Some of the eight, when perturbed, may have very little influence on the outcome. Others, on th...

Re: Machine Learning

In some ways, Tourist Trap, your code reminds me of mathematical optimisation. We could increase a train fare and make more money. We could increase it further and make more money but find that the rate of increase has lessoned. We could increase it further and drive customers away but still make mo...

Re: What is machine learning?

Think of the ton of typing saved in nested loops and ifs if we could find how to train the computer to cleanse itself from excess of nested verbosity! I expect -O3 to do that for me. However, -O3 can be a tad over enthusiastic at times and I wish I had a switch to tell the compiler not to optimise ...

Re: What is machine learning?

<smile> Nice try! I am reminded of "The blind leading the blind". Here is another: The more incompetent a person is the more likely they are to over estimate their competence. I am very competent and know exactly when I am out of my depth. There must be others on this forum who can 'chip i...

I cannot. To write that means you have dabbled with this subject more than I have. <smile>

Re: What is machine learning?

Mersenne Twister comes into its own here with a period of 2^19937 - 1 allowing shuffling a 2080-card deck. I got that from Fisher–Yates shuffle toward the bottom. The table goes as far as a deck of 4199. I wondered what size deck we could go to using CMWC4096 and got 10,940 for a period of 131010, ...
