tf.compat.v1.keras.backend.in_top_k

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].
