i'm new matlab , machine learning , tried compute cost function gradient descent. the function computecost takes 3 arguments: x mx2 matrix y m-dimensional vector theta : 2-dimensional vector i have solution using matrix multiplication function j = computecost(x, y, theta) m = length(y); h = x * theta; serror = (h - y) .^ 2; j = sum(serror) / (2 * m); end but now, tried same without matrix multiplication function j = computecost(x, y, theta) m = length(y); s = 0; = 1:m h = x(i, 1) + theta(2) * x(i, 2); s = s + ((h - y(i)) ^ 2); end j = (1/2*m) * s; end but didn't same result, , first sure (i use before). you have 2 slight (but fundamental) errors - pretty simple errors though can overlooked. you forgot include bias term in hypothesis: h = x(i,1)*theta(1) + x(i,2)*theta(2); %// ^^^^^^ remember, hypothesis when comes linear regression equal theta^{t}*x . didn't include of theta terms - second term...

i developing game application android. problem crashes , displays "unfortunately...has stopped" dialog. running application again not force close app when getting same point, appear every often. what potential reasons might happen? i've done research couldn't find anything you should review logcat possible exceptions. if have no exceptions causing app crash -meaning code aparently "ok"- there's chance application consuming lots of memory. if application making garbage collector overwork, android may shut down application. you must take care not overcreating objects, or leaving load behind cleaned garbage collector. means, if can reuse objects, that's idea. there's <application> element in android manifest. can set there attribute named android:largeheap="true" . in way android assign more memory application. do last resort. try first improve object management in app. ain't easy task, luck.

i want have dynamic amount of divs (sometimes 3, 10 etc), should colored based on color gradient (say green red). so, when there 2 divs, make first 1 #0f0 , second 1 #f00 . when there 10 divs, make first , last same, between change gradually green red. is there way pure css? if not, how javascript? i'm thinking doing javascript right now, it's gonna reaaally complicated way think it. advice? thanks here fiddle want ;) https://jsfiddle.net/tkzr99vx/ it create div amount pass in createdivs method. use rgb values did simpler code. still can use hex values have convert rgb.
