Poly Encoder - Zero Shot Classification

Our model is a Multilabel Classification Model designed to classify texts into various predefined categories using a bidirectional transformer encoder (BERT-like). By leveraging the Poly encoder architecture, the model effectively considers the interaction between the text and the labels while beein gvery fast at inference. This approach demonstrates superior performance compared to the previous bi-encoder architecture and superior inference speed compared to cross encoder. Consequently, it offers a practical alternative to Large Language Models (LLMs), which, despite their versatility, are often too costly and large for resource-constrained environments.

Usage

python

from model import PolyEncoderModel

texts = [
    "The wildlife conservation program is focused on protecting endangered species in Africa.",
    "The government announced a new initiative to combat poverty in rural areas.",
    "A celebrity chef has opened a new restaurant specializing in vegan cuisine."
    ]
batch_labels = [

        ["Conservation", "Business", "Animals", "Africa"],
        ["Politics", "Social Issues", "Economy", "Technolgy"],
        ["Food", "Business","Politics", "Vegan"]

    ]
# Load the model
model = CrossEncoderModel("sabdou/poly-encoder-model", max_num_labels=6)
# Prediction with JSON output
predictions = model.forward_predict(texts, batch_labels)
print("Predictions:", predictions)

Expected Output

    {'text': 'The wildlife conservation program is focused on protecting endangered species in Africa.',
  'scores': {'Conservation': 1.0,
             'Business': 0.0,
             'Animals': 1.0,
             'Africa': 0.99}},

 {'text': 'The government announced a new initiative to combat poverty in rural areas.',
  'scores': {'Politics': 1.0,
             'Social Issues': 0.99,
             'Economy': 1.0,
             'Technolgy': 0.0}},

 {'text': 'A celebrity chef has opened a new restaurant specializing in vegan cuisine.', 
 'scores': {'Food': 1.0,
            'Business': 1.0, 
            'Politics': 0.0, 
            'Vegan': 1.0}}]
