Now, if the true function were boolean OR, then the perceptron would have correctly generalized from three training instances to the full set of instances.
现在，如果true函数是布尔或，那么感知器将从三个训练实例中归纳出所有的实例。

So even though we think of conditions as being Boolean values true or false, really underneath the hood true means anything other than zero.
