构建 SVM 抛出错误，因为我的训练数组有一个额外的维度

Question

我正在创建一个支持向量机。下面的模型读取以“log”开头的数组作为 SVM 图中的向量。数组 log15-log21 将被分类为“c”，而行 log22-log36 将被分类为“d”。目标是以“日志”行的格式为 svm 提供另一个向量，并让 svm 将其标记为“c”或“d”。

from sklearn import svm

log15 = [0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0]

log17 = [0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0]
log18 = [0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0]
log19 = [0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0]
log20 = [0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0]

log26 = [0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
log27 = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

log29 = [0, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

log34 = [0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0]
log35 = [0, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
log36 = [0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

cLines = [log15, log16, log17, log18, log19, log20, log21]
dLines = [log22, log23, log24, log25, log26, log27, log28, log29, log30, log31, log32, log33, log34, log35, log36]

X = [lines]
y = [0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]  #0 for c, 1 for d
clf = svm.SVC()
clf.fit(X, y)

print(clf.predict([[0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0]]))

当我运行上面的代码时，我得到这个错误：

Traceback (most recent call last):
  File "C:/Users/craig/Code/Python Programs/TensorFlowLabs/svm.py", line 34, in <module>
    clf.fit(X, y)

    % (array.ndim, estimator_name)
builtins.ValueError: Found array with dim 3. Estimator expected <= 2.

我看到的在线指南没有用逗号分隔向量，但向量数组中的各个字符具有重要意义，所以我不希望 1 和 0 被“弄乱”，如果有道理。

Answer 1

您正在将 X 定义为一个数组（您正在使用括号）。这就是您收到错误的原因。更改您定义 X 的方式，它应该可以工作：

X = lines
