function binaryCrossentropy$2(yTrue, yPred) {
	  return binaryCrossentropy$1(yTrue, yPred);
	}
Binary crossentropy metric function.

Example:
```js
const x = tf.tensor2d([[0], [1], [1], [1]]);
const y = tf.tensor2d([[0], [0], [0.5], [1]]);
const crossentropy = tf.metrics.binaryCrossentropy(x, y);
crossentropy.print();
```

@param yTrue Binary Tensor of truth.
@param yPred Binary Tensor of prediction, probabilities for the `1` case.
@return Accuracy Tensor.
