Usage

1. angle_emb

python -m pip install -U angle-emb

1. Non-Retrieval Tasks

There is no need to specify any prompts.

from angle_emb import AnglE
from angle_emb.utils import cosine_similarity

angle = AnglE.from_pretrained('WhereIsAI/UAE-Large-V1', pooling_strategy='cls').cuda()
doc_vecs = angle.encode([
    'The weather is great!',
    'The weather is very good!',
    'i am going to bed'
], normalize_embedding=True)

for i, dv1 in enumerate(doc_vecs):
    for dv2 in doc_vecs[i+1:]:
        print(cosine_similarity(dv1, dv2))

2. Retrieval Tasks

For retrieval purposes, please use the prompt Prompts.C for query (not for document).

from angle_emb import AnglE, Prompts
from angle_emb.utils import cosine_similarity

angle = AnglE.from_pretrained('WhereIsAI/UAE-Large-V1', pooling_strategy='cls').cuda()
qv = angle.encode(Prompts.C.format(text='what is the weather?'))
doc_vecs = angle.encode([
    'The weather is great!',
    'it is rainy today.',
    'i am going to bed'
])

for dv in doc_vecs:
    print(cosine_similarity(qv[0], dv))

2. sentence transformer

from angle_emb import Prompts
from sentence_transformers import SentenceTransformer

model = SentenceTransformer("WhereIsAI/UAE-Large-V1").cuda()

qv = model.encode(Prompts.C.format(text='what is the weather?'))
doc_vecs = model.encode([
    'The weather is great!',
    'it is rainy today.',
    'i am going to bed'
])

for dv in doc_vecs:
    print(1 - spatial.distance.cosine(qv, dv))
