Adaptive Sentiment Classifier

An improved sentiment analysis model using the adaptive-classifier library, designed for accurate classification of positive, negative, and neutral sentiments with special focus on technical and informational content.

Model Description

This model is based on the adaptive-classifier library and uses DistilBERT as the underlying transformer. It has been specifically trained to properly classify:

Positive sentiment: Expressions of satisfaction, enthusiasm, approval
Negative sentiment: Expressions of dissatisfaction, frustration, criticism
Neutral sentiment: Factual information, questions, technical descriptions

Key Improvements

✅ Technical Content: Properly classifies technical descriptions as neutral
✅ Questions: Correctly identifies questions as neutral rather than negative
✅ Educational Content: Handles informational text appropriately
✅ Balanced Training: Uses detailed class descriptions for better embeddings

Training Data

Primary Dataset: SetFit/tweet_sentiment_extraction (114 examples)
Training Method: Adaptive classifier with continual learning
Class Distribution: Balanced training with quality filtering
Additional Features: Detailed class descriptions for stronger initial embeddings

Performance

Test Accuracy: 80.0%
Problematic Cases Resolved: 8/10 challenging examples correctly classified
Improvement: 100% increase from baseline accuracy

Benchmark Examples

Text	Expected	Predicted	✓
"Granite Guardian 4 is a type of AI model..."	neutral	neutral	✅
"Do you know what Granite Guardian 4 is?"	neutral	neutral	✅
"Learning is a process of gaining knowledge..."	neutral	neutral	✅
"I love this new technology!"	positive	positive	✅
"This is terrible and I hate it."	negative	negative	✅

Usage

Installation

pip install adaptive-classifier

Basic Usage

python

from adaptive_classifier import AdaptiveClassifier

# Load the model
classifier = AdaptiveClassifier.from_pretrained("MemChainAI/adaptive-sentiment-classifier")

# Make predictions
text = "This is a great product!"
predictions = classifier.predict(text)

# Get top prediction
label, confidence = predictions[0]
print(f"Sentiment: {label} ({confidence:.3f})")

API Integration

This model is designed to work with the MemChain Models API:

python

import requests

response = requests.post(
    "http://localhost:8033/model/sentiment/predict",
    json={"text": "Your text here", "k": 3}
)
result = response.json()

Batch Processing

python

texts = [
    "I love this!",
    "This is terrible.",
    "The system processes data automatically."
]

# Batch prediction
batch_results = classifier.predict_batch(texts)
for i, predictions in enumerate(batch_results):
    label, confidence = predictions[0]
    print(f"Text {i+1}: {label} ({confidence:.3f})")

Training Methodology

Class Descriptions: Started with detailed descriptions of each sentiment class
Quality Examples: Used filtered, high-quality examples from the dataset
Iterative Training: Added examples gradually with evaluation at each step
Continual Learning: Leveraged adaptive classifier's continual learning capabilities

Intended Use

Content Moderation: Analyze user-generated content sentiment
Customer Feedback: Classify customer reviews and feedback
Social Media: Monitor social media sentiment
Technical Documentation: Properly classify technical content as neutral
Educational Content: Handle informational and educational text appropriately

Limitations

Optimized for English text
Best performance on text similar to training data (tweets, reviews, questions)
May require additional examples for domain-specific terminology
Performance may vary on very long texts (>200 characters)

Ethical Considerations

The model should not be used as the sole basis for important decisions
Bias may exist reflecting the training data
Regular evaluation and retraining recommended for production use
Consider cultural and contextual factors when interpreting results
