so trying create own neural network project , challenge myself. have checked math , have made sure correct propagation algorithm outputting numbers tend 1. have checked math , unable find error. anny or tips appreciated , sorry bad variable names, not creative person when comes sort of stuff. main runner class public static void main(string[] args) { net tester = new net(); int[] arrangement = {1, 3, 1}; double[] lister = new double[1]; double[][] inputvalues = {{1.0}, {0.0}};; double[][] expected = {{1.0}, {0.0}}; double[] returned = null, outstored = new double[1000], expectedstored = new double[10000000]; random rand = new random(); int storer = 0, inter = 0; tester.settup(arrangement); for(int j = 0; j < 10000; j++) { storer = rand.nextint(inputvalues.length); returned = tester.feedforward(inputvalues[storer]); tester.backprop(expected[storer], 0.1); if(returned[0] >= 0.5) { inter

for instance, have basic post returns html called "result" using thymeleaf. works , cool. @postmapping("/greeting") public string greetingsubmit(@modelattribute greeting greeting) { return "result"; } but have totally unrelated method, different, , returns not template. @postmapping(value = "/otherstuff", headers = "content-type=multipart/*") public object otherstuff( @requestparam("file") multipartfile datafile ) = { //totally unrelated stuff return resultlist; naturally, exception: org.thymeleaf.exceptions.templateinputexception: error resolving template "/otherstuff", template might not exist or might not accessible of configured template resolvers because i'm intentionally not resolving template. can turn off thyme leaf method? rest api multi-purpose, , rather unhelpful if thyme leaf ends disrupting whole project. thanks wiki

i have class take arraylist parameter: public class foo { private arraylist<bar> bars; public foo(arraylist barlist) { bars = barlist; } } there bug can pass arraylist constructor: // should compile error line foo foo = new foo(new arraylist<string>()); the problem if add case test suite, when bug fixed, can not compile it. there anyway test case? i don't know of language/unit test framework let "test" code should not compile. if can't compile it, there nothing test. can turn on compiler warnings when building. i'm pretty sure passing unparameterized collection big warning in jvm after jdk5. wiki
