Overview

The Spam Detector BERT MoE v2.2 is a state-of-the-art natural language processing model designed to accurately classify text messages and content as spam or non-spam. Leveraging a BERT-based architecture enhanced with a Mixture of Experts (MoE) approach, this model achieves high performance and scalability for diverse spam detection applications.

Model Description

This model is built upon the BERT (Bidirectional Encoder Representations from Transformers) architecture and incorporates a Mixture of Experts (MoE) mechanism to improve its ability to handle a wide variety of spam patterns. The MoE layer allows the model to activate different "experts" (sub-models) based on the input, enhancing its capacity to generalize across different types of spam content.

Model Name: spam-detector-bert-MoE-v2.2
Architecture: BERT with Mixture of Experts (MoE)
Language: English
Task: Text Classification (Spam Detection)

Features

High Accuracy: Achieves superior performance in distinguishing spam from non-spam messages.
Scalable: Efficiently handles large datasets and real-time classification tasks.
Versatile: Suitable for various applications, including email filtering, SMS spam detection, and social media monitoring.
Pre-trained: Ready-to-use with extensive pre-training on diverse datasets.

Usage

Installation

First, ensure you have the Transformers library installed. You can install it via pip:

pip install transformers

Quick Start

Here's how to quickly get started with the Spam Detector BERT MoE v2.2 model using the Hugging Face transformers library:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("AntiSpamInstitute/spam-detector-bert-MoE-v2.2")
model = AutoModelForSequenceClassification.from_pretrained("AntiSpamInstitute/spam-detector-bert-MoE-v2.2")

# Sample text
texts = [
    "Congratulations! You've won a $1,000 Walmart gift card. Click here to claim now.",
    "Hey, are we still meeting for lunch today?"
]

# Tokenize the input
inputs = tokenizer(texts, return_tensors="pt", padding=True, truncation=True)

# Get model predictions
with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits

# Apply softmax to get probabilities
probabilities = torch.softmax(logits, dim=1)

# Get predicted labels
predictions = torch.argmax(probabilities, dim=1)

# Map labels to class names
label_map = {0: "Not Spam", 1: "Spam"}
for text, prediction in zip(texts, predictions):
    print(f"Text: {text}\nPrediction: {label_map[prediction.item()]}\n")

Example

Input:

"Limited time offer! Buy one get one free on all products. Visit our store now!"

Output:

Prediction: Spam

Model Architecture

The Spam Detector BERT MoE v2.2 employs the following architecture components:

BERT Base: Utilizes the pre-trained BERT base model with 12 transformer layers, 768 hidden units, and 12 attention heads.
Mixture of Experts (MoE): Incorporates an MoE layer that consists of multiple expert feed-forward networks. During inference, only a subset of experts are activated based on the input, enhancing the model's capacity without significantly increasing computational costs.
Classification Head: A linear layer on top of the BERT embeddings for binary classification (spam vs. not spam).

Training Data

The model was trained on a diverse and extensive dataset comprising:

Public Spam Datasets: Including SMS Spam Collection, Enron Email Dataset, and various social media spam datasets.
Synthetic Data: Generated to augment the training set and cover a wide range of spam scenarios.
Real-World Data: Collected from multiple domains to ensure robustness and generalization.

The training data was preprocessed to remove personally identifiable information (PII) and ensure compliance with data privacy standards.

Performance

The Spam Detector BERT MoE v2.2 achieves the following performance metrics on benchmark datasets:

Dataset	Accuracy	Precision	Recall	F1 Score
SMS Spam Collection	98.5%	98.7%	98.3%	98.5%
Enron Email Dataset	97.8%	98.0%	97.5%	97.7%
Social Media Spam	96.5%	96.7%	96.3%	96.5%

Note: These metrics are based on the model's performance at the time of release and may vary with different data distributions.

Intended Use

The Spam Detector BERT MoE v2.2 is intended for use in the following applications:

Email Filtering: Automatically classify and filter spam emails.
SMS Spam Detection: Identify and block spam messages in mobile communications.
Social Media Monitoring: Detect and manage spam content on platforms like Twitter and Facebook.
Content Moderation: Assist in maintaining the quality of user-generated content by filtering out unwanted spam.

Limitations

While the Spam Detector BERT MoE v2.2 demonstrates high accuracy, users should be aware of the following limitations:

Language Support: Currently optimized for English text. Performance may degrade for other languages.
Evolving Spam Tactics: Spammers continually adapt their strategies, which may affect the model's effectiveness over time. Regular updates and retraining are recommended.
Context Understanding: The model primarily focuses on textual features and may not fully capture contextual nuances or intent beyond the text.
Resource Requirements: The MoE architecture, while efficient, may require substantial computational resources for deployment in resource-constrained environments.
