对双色球结果预测的一次无聊的尝试

今天晚上突然脑子不知怎么的,本来正在人工给12306验证码做打标工作,突然想看看双色球每期的开奖结果是否有规律

这里下载从03年到今年的每期双色球开奖结果

用t-SNE降维到3维打印出来看看

似乎并没有什么规律

准备用线性回归来拟合一个模型,马上就有一个问题,对于双色球预测,自变量取什么?这是个非常复杂的问题了,而且可能是无解的问题,因为如果双色球是完全的独立随机事件,那也就无法提取出自变量,自然也就没法提取特征空间,这里姑且用开奖期号作为自变量特征,用结果(6维的红球结果,1维的蓝球结果)作为label

    ax.scatter(show_date[:, 0], show_date[:, 1], show_date[:, 2], edgecolor='k', s=40)
    plt.show()

if __name__ == '__main__':
    ori_data = load_historydata()
    np.random.shuffle(ori_data)
    # tsne_data = load_tsnedata(ori_data)

    y_test = Y_data[split_len:]
    print "y_train"
    print y_train

    # Create linear regression object
    regr = linear_model.LinearRegression()

    # Train the model using the training sets
    regr.fit(X_train, y_train)

    # Make predictions using the testing set
    #y_pred = regr.predict(X_train).round()
    y_pred = regr.predict(X_test).round()
    print "y_pred"
    print y_pred

    print "y_pred distinct"
    y_pred_cache = list()
    for line in y_pred:
        line = list(line)
        if line not in y_pred_cache:
            y_pred_cache.append(line)
    for line in y_pred_cache:
        print line

    # 预测的准确度
    print "Prediction accurate: {0}%".format(np.mean(X_test == y_pred) * 100)

线性回归的预测结果如下

y_pred distinct
[5.0, 9.0, 14.0, 19.0, 24.0, 29.0, 9.0]
[5.0, 10.0, 15.0, 19.0, 24.0, 29.0, 9.0]
[5.0, 10.0, 14.0, 19.0, 24.0, 29.0, 9.0]

模型对所有的training set的每一条预测结果都相同,这说明,对于开奖期号来说,开奖结果是一个完全随机的事件

如果考虑每期和每期之间可能有关联性,可以考虑试试用RNN来训练,输入依然是开奖期号

但是反过来也给了我一个启示,在进行机器学习项目的时候,如果train或者test的结果不好或者不符合预期,不要急于去调参数或者换模型,更应该回过头来想想自己给模型输入的特征是否确实隐含了规律,算法是无法对随机事件进行预测的,只有原始数据中确实隐含了规律,使用适当的模型才能从中抽象出模型,特征工程是非常关键的,也是需要长久思考的
