假设在一个神经元上实现AND函数，下表是AND函数的表述:
| X1 | X2 | X1 AND X2 |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
激活函数为：
权重（Weights）和偏差（Bias）哪一组是正确的？
Bias = -1.5, w1 = 1, w2 = 1
Bias = 1.5, w1 = 2, w2 = 2
Bias = 1, w1 = 1.5, w2 = 1.5
以上都不正确
解释：
1. f(-1.5*1 + 1*0 + 1*0) = f(-1.5) = 0
2. f(-1.5*1 + 1*0 + 1*1) = f(-0.5) = 0
3. f(-1.5*1 + 1*1 + 1*0) = f(-0.5) = 0
4. f(-1.5*1 + 1*1+ 1*1) = f(0.5) = 1
带入测试值，“Bias = -1.5, w1 = 1, w2 = 1”正确
1. f(-1.5*1 + 1*0 + 1*0) = f(-1.5) = 0
2. f(-1.5*1 + 1*0 + 1*1) = f(-0.5) = 0
3. f(-1.5*1 + 1*1 + 1*0) = f(-0.5) = 0
4. f(-1.5*1 + 1*1+ 1*1) = f(0.5) = 1
带入测试值，“Bias = -1.5, w1 = 1, w2 = 1”正确
