Cannot use OracleClustering

[Tortoise17]

When I change the default clustering method to OracleClustering, in the config YAML file, there is error Parameter 'method' doesnot exist. If you can guide how to use other method of clustering.

OracleClustering isn't a drop-in you can select in the config. It's an oracle — it clusters using the ground-truth reference annotation, so it only works in a benchmarking/evaluation setting where you actually pass the reference. It has nothing to cluster on unlabeled audio, and it doesn't accept the same parameters as AgglomerativeClustering (which is why swapping it into the YAML errors on method — that param exists on Agglomerative, not on Oracle). Its only purpose is to measure the upper bound of your pipeline's accuracy given perfect clustering.

If what you actually want is to change or tune real clustering, stay on AgglomerativeClustering and adjust its knobs. The two that matter:

• threshold — the main lever; lower splits into more speakers, higher merges more.
• method — the linkage (centroid, average, …).

You can set them by re-instantiating the pipeline:

pipeline.instantiate({
    "clustering": {"method": "centroid", "threshold": 0.7},
    # ... keep the pipeline's other params
})

Or, simpler, steer the result at call time with num_speakers / min_speakers / max_speakers. Reserve OracleClustering for offline experiments where you have labels and want to know "how good could this pipeline be if clustering were perfect."
