ClassifAIer 0.1.4

A library for text classification using LangChain embeddings and scikit-learn classifiers.

ClassifAIer

ClassifAIer is a Python library that combines scikit-learn classifiers with LangChain embedding libraries, enabling seamless text classification using embeddings from large language models. This library offers a user-friendly interface, allowing you to classify text data in a human-like manner.

Features

• Embedding Support: Ability to work with embeddings from large language models like OpenAI and compatible with embeddings supported by LangChain.
• Parametric Classifiers: Compatibility with a wide range of classifiers from scikit-learn (e.g., RandomForestClassifier, KNeighborsClassifier, etc.).
• Easy to Use: Simplifies text classification tasks with a user-friendly API.
• Save and Load: Allows you to save and reload trained models for reuse.

Requirements

To use this library, you need Python 3.7 or higher. The required packages will be automatically installed when you install this library.

• scikit-learn
• langchain-core
• langchain
• numpy

Installation

You can install the required libraries using the following command:

pip install ClassifAIer

Usage

from classifaier import ClassifAIer
from langchain.embeddings import OpenAIEmbeddings

# Initialize the embedding provider
embedding_provider = OpenAIEmbeddings(api_key='YOUR_API_KEY')

random_forest_classifier_params = {
    "n_estimators": 100,
    "max_depth": None,
    "min_samples_split": 2,
    "min_samples_leaf": 1,
    "random_state": 42
}

random_forest_classifier = RandomForestClassifier(**random_forest_classifier_params)

# Create a classifier instance
classifier = ClassifAIer(embedding_provider=embedding_provider, classifier=random_forest_classifier)

# Prepare your data
texts = ["This is a positive review.", "This is a negative review."]
labels = ["positive", "negative"]

# Train the model
classifier.fit(texts, labels)

# Make predictions
positive_prediction = classifier.predict("I love this product!")
print(positive_prediction)  # Output: 'positive'

negative_prediction = classifier.predict("I hate this service.")
print(negative_prediction)  # Output: negative

# Save the model
classifier.save("my_classifier.pkl")

# Load the model
loaded_classifier = ClassifAIer.load("my_classifier.pkl", embedding_provider)
