tensorboard - Stopping Gradients for a subset of a tensor in tensorflow -


i have tensorflow graph set, input variable (x = tf.variable() ) , resulting error term (err). able update on subset of elements in x.

one way using tf.stop_gradient(), require rebuilding graph again scratch apply stop gradient operator. way without having go through rebuilding graph.

if can't rebuild graph, solution save values of x prior update, , later tf.assign values elements of x want preserve.

service - Android MediaPlayer calls onCompletion before it already finished -

guys, trying implement android foreground service play music url. mediaplayer starts , play song after while calls oncompletion() when song not finished. set onerrorlistener it's not called... what have done: checked connection url > ok checked song duration > ok implemented partial wake lock > ? app doesn't crash, mediaplayer call oncompletion , don't know do. here have service , activity code. in advance: service: public class musicservice extends service implements mediaplayer.onpreparedlistener, mediaplayer.onerrorlistener, mediaplayer.oncompletionlistener{ //filter broadcasts public final static string action_filter = "action_hhgroups"; //media actions: public final static string action_play_one = "action_play_one"; //foreground: public static boolean is_foreground = false; public final static int foreground_service = 101; public final static string action_start_foreground = "action_start_foreground"; pu...

javascript - Training Neural Network to play flappy bird with genetic algorithm - Why can't it learn? -

Image
i have been learning neural networks , genetic algorithms, , test learning, have tried make ai learns play flappy bird: i have left running @ least 10 hours (overnight , longer), fittest member still fails show significant advancements in intelligence when began simulation apart avoiding floor , ceilings. inputs rays (as can see above) act sight lines, , network fed in lengths, , birds vertical velocity. seems best bird ignoring sight lines except horizontal one, , when short, jumping. output number between 0 , 1, if output larger 0.5, bird jumps. there 4 hidden layers, 15 neurons each, input layer feeding forward first hidden layers, 1st hidden layer feeding forward 2nd 1 ... , final hidden layer feeding forward output, dna of bird array of real numbers representing weights of neural networks, have made project using same style of neural network, , genetic algorithm, in ants had travel food, , worked perfectly. here code: https://github.com/karan0110/flappy-bird-ai please ...
