Revolutionizing Privacy in Machine Learning: The Advent of the Reorder-Slice-Compute Paradigm

As Seen On


In today’s data-driven landscape, the trade-off between privacy and utility stands as a significant challenge. The burgeoning development and application of machine learning (ML) and data analytics algorithms have illuminated the obstacles thrown up by this complex relationship. Data privacy issues involve terms like the cost of composition and differential privacy – a concept that is integral to safeguarding personal data in this digital era.

The RSC Paradigm

In the early days of tackling privacy issues in machine learning, strategies such as DP-SGD (Differentially Private Stochastic Gradient Descent) were deployed. While effective up to an extent, these strategies had limitations. They struggled to maintain a balance between achieving optimal algorithmic performance and ensuring the sanctity of privacy. The issue spun around the concept of composition cost – the cumulative risk of privacy leakage with each successive application of privacy-preserving computations.

With the objective of navigating around these concerns, the Reorder-Slice-Compute (RSC) paradigm was unveiled at STOC 2023. Anchored on adaptive slice selection, the groundbreaking RSC paradigm sidesteps the cumbersome composition cost problem innovatively. The RSC paradigm follows a structure that focuses on boosting utility without a commensurate compromise on data privacy.

Research testing this promising paradigm exhibits results that underscore its potential. Unlike its predecessors, the RSC analysis managed to eliminate the dependence on the number of steps. This formidable feat has been a critical factor in buttressing the privacy guarantee, thereby solidifying confidence in its reliability.

The applications of the RSC paradigm are varied and essential. Examples include solutions to the private interval point problem, various aggregation tasks, and the private learning of axis-aligned rectangles. In these contexts, the RSC paradigm’s ingenuity in slice selection, combined with its novel analysis, results in impressive privacy-preserving solutions.

On the machine learning training ground, the RSC paradigm’s potential shines through again, providing new pathways for ML model training. It facilitates a data-dependent selection order of training examples, a game-changer for the process. Moreover, the integration of the RSC system with DP-SGD ushers in a promising era of privacy preservation. The collaboration results in a cutting-edge model that arrests the deterioration of privacy.


Guiding us into a new era of data confidentiality, the RSC paradigm is a revolutionary solution to the enduring balance between privacy and utility in our data-centric world. Its application reaches further, proving instrumental in the training of privacy-preserving machine learning models. This development is especially valuable in an age where privacy is a price often paid for technological progress.

In summary, the advent of the Reorder-Slice-Compute (RSC) paradigm brings new hope for addressing the complexities and challenges of privacy in the realm of machine learning and data analytics. It serves as a reminder that the harmony between privacy and technological utility is possible and within reach. This development also flaunts the vast potential that lies in the future of machine learning and data analysis, ensuring that progress doesn’t come at the expense of individual privacy.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
