Multi2ConvAI-Quality: English logistic regression model using fasttext embeddings
This model was developed in the Multi2ConvAI project:
- domain: Quality (more details about our use cases: (en, de))
- language: German (de)
- model type: logistic regression
- embeddings: fastText embeddings
How to run
Requires:
- multi2convai
- serialized fastText embeddings (see last section of this readme or these instructions)
Run with one line of code
After installing multi2convai and locally available fastText embeddings you can run:
# assumes working dir is the root of the cloned multi2convai repo
python scripts/run_inference.py -m multi2convai-quality-de-logreg-ft
>>> Create pipeline for config: multi2convai-quality-de-logreg-ft.
>>> Created a LogisticRegressionFasttextPipeline for domain: 'quality' and language 'de'.
>>>
>>> Enter your text (type 'stop' to end execution): Starte das Programm
>>> 'Starte das Programm' was classified as 'no.start' (confidence: 0.8943)
How to run model using multi2convai
After installing multi2convai and locally available fastText embeddings you can run:
# assumes working dir is the root of the cloned multi2convai repo
from pathlib import Path
from multi2convai.pipelines.inference.base import ClassificationConfig
from multi2convai.pipelines.inference.logistic_regression_fasttext import (
LogisticRegressionFasttextConfig,
LogisticRegressionFasttextPipeline,
)
language = "de"
domain = "quality"
# 1. Define paths of model, label dict and embeddings
model_file = "model.pth"
label_dict_file = "label_dict.json"
embedding_path = Path(
f"../models/embeddings/fasttext/de/wiki.200k.de.embed"
)
vocabulary_path = Path(
f"../models/embeddings/fasttext/de/wiki.200k.de.vocab"
)
# 2. Create and setup pipeline
model_config = LogisticRegressionFasttextConfig(
model_file, embedding_path, vocabulary_path
)
config = ClassificationConfig(language, domain, label_dict_file, model_config)
pipeline = LogisticRegressionFasttextPipeline(config)
pipeline.setup()
# 3. Run intent classification on a text of your choice
label = pipeline.run("Starte das Programm")
label
>>> Label(string='neo.start', ratio='0.8943')
