function categoricalAccuracy$1(yTrue, yPred) {
	  return categoricalAccuracy(yTrue, yPred);
	}
Categorical accuracy metric function.

Example:
```js
const x = tf.tensor2d([[0, 0, 0, 1], [0, 0, 0, 1]]);
const y = tf.tensor2d([[0.1, 0.8, 0.05, 0.05], [0.1, 0.05, 0.05, 0.8]]);
const accuracy = tf.metrics.categoricalAccuracy(x, y);
accuracy.print();
```

@param yTrue Binary Tensor of truth: one-hot encoding of categories.
@param yPred Binary Tensor of prediction: probabilities or logits for the
  same categories as in `yTrue`.
@return Accuracy Tensor.
