## Utility functions for LSH models

### Description

Utility functions for LSH models

### Usage

    ml_approx_nearest_neighbors(model, dataset, key, num_nearest_neighbors,
      dist_col = "distCol")

    ml_approx_similarity_join(model, dataset_a, dataset_b, threshold,
      dist_col = "distCol")

### Arguments

`model` | A fitted LSH model, returned by either `ft_minhash_lsh()` or `ft_bucketed_random_projection_lsh()`.
`dataset` | The dataset to search for nearest neighbors of the key.
`key` | Feature vector representing the item to search for.
`num_nearest_neighbors` | The maximum number of nearest neighbors.
`dist_col` | Output column for storing the distance between each result row and the key.
`dataset_a` | One of the datasets to join.
`dataset_b` | Another dataset to join.
`threshold` | The threshold for the distance of row pairs.
