Hierarchy Transformers (HiTs)

Hierarchy Transformer

Hierarchy Transformer (HiT) is a framework that enables transformer encoder-based language models (LMs) to learn hierarchical structures in hyperbolic space.

Get Started

Install hierarchy_tranformers (check our repository) through pip or GitHub.

Use the following code to get started with HiTs:

from hierarchy_transformers import HierarchyTransformer

# load the model
model = HierarchyTransformer.from_pretrained('Hierarchy-Transformers/HiT-MiniLM-L12-WordNetNoun')

# entity names to be encoded.
entity_names = ["computer", "personal computer", "fruit", "berry"]

# get the entity embeddings
entity_embeddings = model.encode(entity_names)
