android getContext Method -


i'm interested in getcontext() method how works, example, wrote recycle view

@override  public recycleview.viewholder oncreateviewholder(viewgroup parent ,int viewtype) { view view =layoutinflater.from(parent.getcontext()).inflate(r.layout.list_item,parent,false);}

and call on fragment class , fragment class defined mainactivity question here how context method return mainactivity? how context understand? @ method android studio, didn't understand well

for ultimate reference: context | android developers

long story short, view class, , of it's subclasses (like viewgroup), have defined function called getcontext() returns context object. class abstract , implementation provided android system, why actual functionality not easy understand. allows access global information application's environment, such themes, resources, etc. pretty magical, magical aspect can costly if aren't careful. easy leak context object, can eat ram on device.

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 ...
