问题 I want my neural network to convert a negative value into a positive value. Theoretically this can be done using a ReLU function and 1 node which learns the input weight to be -1 (so a negative input is multiplied by -1 = positive input. It just keeps on outputting 0. Code below. I used -1 as input values to see if it could learn on at least a single input. I tried adding more layers but it doesn't help see edit, IT DID help if I add more train_input = np.asarray([[-1]]*10000) # Input arr of

问题 I want to train a neural network with the sine() function. Currently I use this code and the (cerebrum gem): require 'cerebrum' input = Array.new 300.times do |i| inputH = Hash.new inputH[:input]=[i] sinus = Math::sin(i) inputH[:output] = [sinus] input.push(inputH) end network = Cerebrum.new network.train(input, { error_threshold: 0.00005, iterations: 40000, log: true, log_period: 1000, learning_rate: 0.3 }) res = Array.new 300.times do |i| result = network.run([i]) res.push(result[0]) end

问题 I currently have a lot of data that will be used to train a prediction neural network (gigabytes of weather data for major airports around the US). I have data for almost every day, but some airports have missing values in their data. For example, an airport might not have existed before 1995, so I have no data before then for that specific location. Also, some are missing whole years (one might span from 1990 to 2011, missing 2003). What can I do to train with these missing values without

问题 I was doing some research on training deep neural networks using tensorflow. I know how to train a model. My problem is i have to train the same model on 2 different computers with different datasets. Then save the model weights. Later i have to merge the 2 model weight files somehow. I have no idea how to merge them. Is there a function that does this or should the weights be averaged? Any help on this problem would be useful Thanks in advance 回答1: It is better to merge weight updates

问题 I have to code AI to control many propulsion jets for a spaceship in a game. For simplicity :- Let the space be 1D. Spaceship is a point and there is only 1 jet. Rule and problem Let x , v and a are position, velocity, acceleration of the spaceship. Let F be the force of jet that apply to the ship. I know mass m of the spaceship, let's say m =1. Here is a summary :- acceleration = F/m; v = vOld + acceleration*timestep; x = xOld + v*timestep; The objective is to land the ship on a certain

问题 I'm looking for an Ada constructed framework for AI. I think Ada would be perfect for implementing temporal and stochastic paradigms due to its tasking and real-time mechanisms, but did not find anyone who tried to make such a libraries. Actually I did not find strong implementations on other languages too. For C# I found http://www.c-sharpcorner.com/1/56/, and for C++ I found http://mind.sourceforge.net/cpp.html but both did not get much popularity. Maybe java has good AI libraries too, but

问题 I have an online RPG game which I'm taking seriously. Lately I've been having problem with users making bogus characters with bogus names, just a bunch of different letters. Like Ghytjrhfsdjfnsdms, Yiiiedawdmnwe, Hhhhhhhhhhejejekk. I force them to change names but it's becoming too much. What can I do about this? Could I somehow check so at least you can't use more than 2 of the same letter beside each other?? And also maybe if it contains vowels 回答1: I would recommend concentrating your

问题 Given a object which may move forward, backward, left and right at a given X,Y point. How to efficiently direct the object to a X,Y point using the given movement mechanics in the most efficient and human natural way. The object is available for movement in real time, you may tell them to "startMoving|Direction|()" and "stopMoving|Direction|()". Though as a additional twist and the part I am having trouble with, is the facing of the object is never known, only its current location is known,

问题 Hello i try to create simple AI program , so i define two grammar and load them and i get this error at least one grammar must be loaded before doing a recognition. the error from visual studio is : An exception of type 'System.InvalidOperationException' occurred in System.Speech.dll but was not handled in user code Additional information: At least one grammar must be loaded before doing a recognition. here is the code this is the class class DefineGrammar { /// <summary> /// Define Choices /
