Welcome to My Blog

Welcome to my personal blog! I’m Yingtai Xiao, a Research Scientist at TikTok Privacy Innovation Lab.

About This Blog

I’ll be sharing my thoughts on various topics including:

  • Differential Privacy: Theory and practical applications
  • Machine Learning: Privacy-preserving techniques in ML
  • Research Insights: Learnings from academic and industry research

A Quick Demo

Here’s some code highlighting:

import numpy as np

def add_laplace_noise(value, sensitivity, epsilon):
    """Add Laplace noise for differential privacy."""
    scale = sensitivity / epsilon
    noise = np.random.laplace(0, scale)
    return value + noise

And some math for differential privacy:

\[\Pr[\mathcal{M}(D) \in S] \leq e^\epsilon \cdot \Pr[\mathcal{M}(D') \in S] + \delta\]

Where \(\mathcal{M}\) is a randomized mechanism, and \(D, D'\) are neighboring databases.

Stay Tuned
