 * Initializing with token embeddings (computed from FastText) leads to noticible accuracy gain in Astec. Please ensure that the token embedding file is available in data directory, if 'init=token_embeddings', otherwise it'll throw an error.
 * Config files are made available in deepxml/configs/<framework>/<method> for datasets in XC repository. You can use them when trying out Astec/DeepXML on new datasets.
