java - 神经网络没有主动响应已学习的内容

Question

这个神经网络的界面被构建为一个不和谐的机器人。您可以在 https://discord.gg/N5Bke3z 找到它。如果重置命令在学习命令之前完成，则它可以正常工作。学习命令没有按照我的消息监听器中的指示进行响应。检查覆盖范围后，我注意到它跳过了不应该发生的事情，例如 if else 语句。我使用的两个api是javacord https://github.com/BtoBastian/Javacord ，以及我用于处理数据的个人 api https://github.com/NicksWorld/Networking-DataTypes 。我的代码将缺少不和谐机器人 token ，但我向您保证 token 不是问题。除了 javacord 的启动日志之外，控制台日志为空:

Oct 29, 2017 10:33:48 AM de.btobastian.javacord.utils.JavacordLogger info INFO: No SLF4J compatible logger was found. Using default javacord implementation!

如果我能得到任何帮助，我将不胜感激。我的代码位于 https://github.com/NicksWorld/Java-neural-network如下: Bot.java:

package Discord;

import com.google.common.util.concurrent.FutureCallback;

import Discord.message.Message;
import de.btobastian.javacord.DiscordAPI;
import de.btobastian.javacord.Javacord;

public class Bot {
    public static void main(String[] args) {
        //get login info
        DiscordAPI api = Javacord.getApi("*****************", true);
        //login
        api.connect(new FutureCallback<DiscordAPI>() {
            @Override
            public void onSuccess(final DiscordAPI api) {
                //set game and start listener
                api.setGame("Learning through Network001's algorithms");
                api.registerListener(new Message());
            }

            @Override
            public void onFailure(Throwable t) {
                t.printStackTrace();
            }
        });
    }
}

编辑:我发现失败计数没有在正确的点重置，从而修复了该错误。

Answer 1

我做了很多调试，并将问题定位到一行。失败计数在阻止失败计数结束学习过程时被重置。 Network.java 的新代码是:

    //End initialize collection of training data


    //Initialize result variable

    public Double datasetResult = 0.0;

    //End initialize result variable


    //Initialize fails variable

    public Integer fails = 0;

    //End initialize fails variable


    //Initialize done learning boolean

    public boolean doneLearning = false;

    //End initialize done learning boolean


    //Initialize weights

    //Initialize column 3's weight
    public double ColumnWeight3 = Math.round(Math.random());
    //Initialize column 4's weight
    public double ColumnWeight4 = Math.round(Math.random());

    //End initialize weights


    //Function to check weights against all datasets

    public boolean checkWeights() {
