Project Focus:

• Objective: Predict the success of marketing content (images, videos, and text) before campaigns go live using multi-modal AI models.
• Method:
• Apply customer research (survey/NLP data) alongside computer vision and text models.
• Build models that can take a new creative (image, video, or ad copy) and predict its expected performance.
• Reduce reliance on traditional lengthy A/B testing by using pre-testing AI models.
• Provide detailed post-campaign insights, including content attributes that worked (or didn’t) for different audience segments (e.g., high spenders).
• Backtesting:
• AI models should be able to simulate performance against historical data to validate predictions.
• Models should also score new content (ads/videos/copy) before it is launched.

Key Technical Requirements:
1. Multi-Modal AI Expertise

• Ability to work with images, video, and text data simultaneously.
• Experience building or applying multi-modal models (e.g., combining visual and textual inputs).

2. Experience with Open-Source Models

• Ideally familiar with OpenAI CLIP or similar vision-language models.
• Should know how to adapt and apply open-source AI models to real-world data (not just academic familiarity).

3. Computer Vision and NLP Skills

• Computer vision: Practical knowledge – but not traditional CV (e.g., object detection) – focus is on newer multimodal models.
• NLP: Able to process and leverage customer research data (e.g., surveys, text responses).

4. Programming and Statistical Foundation

• Strong coding skills – must be a programmer at heart, not just a “tool user.”
• Solid background in statistics and mathematics to build reliable, explainable models.
• Should understand model evaluation, backtesting, and simulation of campaign performance.

5. Content Performance Modeling

• Build models that:
• Predict creative success for new ads, videos, and text.
• Backtest models using historical data.
• Score and provide insights into what aspects of content perform best.
