neural network - How to select number of Input layers, hidden layers and output layer using newff in Matlab? -


i using newff stock price forecasting project, trying setup back-propagation feed forward ann of 4 inputs, 1 hidden layers , 1 output layer (4-1-1). have read many forums learn how correctly specify these parameters newff, every forum/post copy/paste matlab newff definition (that not able understand new matlab , neural networks). can please let me know how setup 4-1-1 ann using newff?

example:

input = [0.1 0.8; 0.1 0.75; 0.01 0.8; 0.5 0.6];  output = [1 2]; nbhiddenneurons = 1; net = newff(input, output, nbhiddenneurons);

this give 4-1-1 ann using newff.

enter image description here

note: newff() obsoleted in r2010b nnet 7.0. recommended function feedforwardnet.

java Extracting Zip file -

i'm looking way extract zip file. far have tried java.util.zip , org.apache.commons.compress, both gave corrupted output. basically, input zip file contain 1 single .doc file. java.util.zip: output corrupted. org.apache.commons.compress: output blank file, 2 mb size. so far commercial software winrar work perfectly. there java library make use of this? this method using java.util library: public void extractzipnative(file filezip) { zipinputstream zis; stringbuilder sb; try { zis = new zipinputstream(new fileinputstream(filezip)); zipentry ze = zis.getnextentry(); byte[] buffer = new byte[(int) ze.getsize()]; fileoutputstream fos = new fileoutputstream(this.tempfolderpath+ze.getname()); int len; while ((len=zis.read(buffer))>0) { fos.write(buffer); } fos.flush(); fos.close(); } catch (filenotfoundexception e) { // todo auto-generated catch block ...

i ask how make loading screen (just picture or something) appears while program being loaded, , disappears when program has finished loading. in fancier versions, have seen process bar (%) displayed. how can have that, , how calculate % show on it? i know there form_load() event, not see form_loaded() event, or % property / attribute anywhere. all need create 1 form splash screen , show before main start showing landing page , close splash once landing page loaded. class splashform { //delegate cross thread call close private delegate void closedelegate(); //the type of form displayed splash screen. private static splashform splashform; static public void showsplashscreen() { // make sure launched once. if (splashform != null) return; thread thread = new thread(new threadstart(splashform.showform)); thread.isbackground = true; thread.setapartmentstate(apartmentstate.sta); thread....
