Cross-Modal Audience Intelligence Platform (CAIP)

Version Python License

A comprehensive multimodal AI system that leverages visual, textual, and structured data to identify causal drivers of viewer engagement. CAIP combines state-of-the-art deep learning models with causal inference techniques to provide actionable insights for content creators and marketers.

🔍 Overview

The Cross-Modal Audience Intelligence Platform (CAIP) is designed to:

  1. Analyze content across multiple modalities (text, image, metadata)
  2. Identify causal factors that drive audience engagement
  3. Predict counterfactual outcomes for content modifications
  4. Recommend optimizations to maximize viewer engagement
  5. Explain results through transparent causal relationships

🏗️ Architecture

CAIP consists of several interconnected components:

┌────────────────┐    ┌─────────────────┐    ┌───────────────────┐
│ Data Pipeline  │───▶│  Model Pipeline  │───▶│  Causal Pipeline  │
└────────────────┘    └─────────────────┘    └───────────────────┘

Key Components:

  • Data Layer: Connectors to various data sources, preprocessing pipelines, and feature engineering
  • Model Layer: Visual models (CLIP), text models (RoBERTa), and multimodal fusion models
  • Causal Layer: Structural causal models, counterfactual analysis, and causal feature identification
  • RAG System: Retrieval-augmented generation for content recommendations and explanations
  • Serving Layer: REST API, model serving infrastructure, and containerized deployment

🚀 Getting Started

Prerequisites

  • Python 3.9+
  • Docker and Docker Compose (for containerized deployment)
  • CUDA-compatible GPU (recommended for training)

Installation

  1. Clone the repository:

    git clone https://github.com/yourusername/cross_modal_audience_platform.git
    cd cross_modal_audience_platform
  2. Set up the environment and install dependencies:

    ./run_local.sh setup
  3. Run tests to verify your installation:

    ./run_local.sh test

🛠️ Development Workflow

CAIP uses a modular architecture with well-defined interfaces between components. The development workflow is streamlined using the run_local.sh script:

# Run all unit tests
./run_local.sh test

# Run integration tests
./run_local.sh integration

# Run causal tests with specific configuration
./run_local.sh causal --config complex

# Collect training data
./run_local.sh collect --limit 1000

# Fine-tune the model
./run_local.sh finetune --epochs 10

# Start API server locally
./run_local.sh api

# Start API using Docker
./run_local.sh docker

For more options, run:

./run_local.sh help

📊 Causal Analysis

CAIP employs a structured approach to causal analysis:

  1. Feature Identification: Extract relevant features from visual and textual content
  2. Causal Discovery: Learn the causal graph structure from observational data
  3. Effect Estimation: Quantify the causal effect of content features on engagement
  4. Counterfactual Analysis: Predict engagement under hypothetical content modifications
  5. Recommendation Generation: Suggest content changes to optimize engagement

🔄 Fine-tuning Pipeline

To fine-tune models on your own data:

  1. Collect data:

    ./run_local.sh collect --source your_data_source --limit 5000
  2. Fine-tune the model:

    ./run_local.sh finetune --config configs/fine_tuning.yaml
  3. Evaluate the fine-tuned model:

    python scripts/evaluate_model.py --model-path models/saved/fusion_model_best.pt

🖥️ API Usage

Once the API server is running, you can interact with it using HTTP requests:

import requests
import json

# Analyze content
response = requests.post(
    "http://localhost:5000/api/v1/analyze",
    headers={"Authorization": f"Bearer {api_key}"},
    json={
        "text": "Exciting new product launch!",
        "image_url": "https://example.com/product_image.jpg",
        "metadata": {"category": "technology", "target_audience": "professionals"}
    }
)

# Parse results
results = response.json()
print(json.dumps(results, indent=2))
