Vision-Language Models
CATA: Continual Machine Unlearning via Conflict-Averse Task Arithmetic
Vision-language models (VLMs) have shown remarkable ability in aligning visual and textual representations, enabling a wide range of multimodal applications. However, their large-scale training data inevitably raises concerns about privacy, copyright, and undesirable content, creating a strong need for machine unlearning.
Executive Impact & Key Metrics
This paper introduces CATA, a novel method for continual machine unlearning in Vision-Language Models (VLMs), addressing the critical challenge of knowledge re-emergence. By representing forget requests as task vectors and aggregating them in a conflict-averse manner, CATA ensures that previously forgotten information remains suppressed across sequential updates, while maintaining high model utility and performance on retained knowledge. This approach significantly improves the persistence and effectiveness of unlearning, making it suitable for real-world VLM deployments requiring dynamic data removal.

CATA introduces a novel mechanism for handling sequential unlearning requests in VLMs, focusing on preventing knowledge re-emergence. Traditional unlearning methods often struggle with this, as subsequent updates can inadvertently restore previously forgotten information. CATA addresses this by employing a conflict-averse task arithmetic strategy, ensuring that unlearning effects are durable over time, which is critical for trustworthy AI systems.

Beyond merely removing target data, CATA prioritizes maintaining the utility and performance of the VLM on retained data and downstream tasks. This fidelity is crucial for practical enterprise deployment, where models must continue to perform robustly on their core functions even after unlearning specific content. CATA’s approach ensures that the model's overall generalization capabilities are preserved, leading to a reliable and versatile AI asset.

The ability of an unlearning method to scale with an increasing number of sequential removal requests is paramount for enterprise applications. CATA is designed to handle continual unlearning efficiently, ensuring that performance does not degrade significantly as more tasks are processed. This scalability allows organizations to adapt their VLMs to evolving privacy policies and content moderation needs without incurring prohibitive computational costs or sacrificing model quality over time.

CATA in Action: Managing Evolving Data Policies
A large enterprise utilizing a VLM for content moderation faces dynamic privacy regulations. With CATA, they can swiftly remove specific, sensitive content from their deployed VLM as new compliance requirements emerge. Instead of costly retraining, which can take weeks, CATA processes each unlearning request in an online manner, preserving the model's overall performance and ensuring compliance without service interruption. This agility provides a significant competitive advantage.
