tf.keras.backend.in_top_k(
    predictions, targets, k
)

Arguments
`predictions`	A tensor of shape `(batch_size, classes)` and type `float32`.
`targets`	A 1D tensor of length `batch_size` and type `int32` or `int64`.
`k`	An `int`, number of top elements to consider.

Returns
A 1D tensor of length `batch_size` and type `bool`. `output[i]` is `True` if `predictions[i, targets[i]]` is within top-`k` values of `predictions[i]`.
