degree = 5
x1 = data2['Test 1']
x2 = data2['Test 2']

data2.insert(3, 'Ones', 1)

for i in range(1, degree):
# for j in range(0, i):#这里x2始终不能达到最高次幂,修改后就好了,修改后accuracy 可达97%
for j in range(0, i+1):
data2['F' + str(i) + str(j)] = np.power(x1, i-j) * np.power(x2, j)

我发出 issues#110 后才看到你也发现了一样的问题, 但你这个修改完后的代码是不是不会达到题目中要求的最高6次幂,一共28维的X呢?

我在#110中的代码可以生成到最高6次幂,一共28维,但准确率只能达到80多%
