9. Future Directions and Emerging Trends
Current research trends in composition algorithms within the realm of differential privacy include:
1. Fine-Grained Privacy Analysis: Researchers are developing techniques to provide finer-grained privacy analysis that takes into account query-specific properties, leading to more accurate and tailored privacy guarantees.
2. Adaptive Composition: Addressing the challenges of adaptive data analysis, researchers are exploring advanced techniques that dynamically adjust privacy parameters to accommodate changing query behaviours.
3. Non-Additive Noise Handling: As non-additive noise mechanisms gain attention, research is focused on developing composition techniques that can effectively combine results from differentially private analyses with varying noise distributions.
4. Cross-Algorithm Composition: Exploring how different differential privacy mechanisms can be combined in a privacy-preserving way, considering scenarios where multiple mechanisms are used in conjunction.
