Federated Learning & AI Privacy

Federated learning, differential privacy, and privacy-preserving machine learning. We cover how models train across devices and institutions without centralizing data, what privacy guarantees actually cost in accuracy, and the benchmarks and frameworks shaping the field, always traced back to the original research.

FCUCR: Federated Continual Recommendation That Remembers You Without Storing Your Data

Researchers from Jilin University and the University of Technology Sydney built a federated continual recommendation framework that solves two problems nobody had tackled together: forgetting who you used to be, and not knowing enough about people like you — all…

SegTrans: The Transfer Attack That Finally Broke Segmentation Models (Without Extra Compute)

Segmentation models correct each other’s mistakes through a “tight coupling” phenomenon – which makes them brutally hard to fool in a black‑box setting. Researchers discovered that by destroying global semantic integrity and remapping local features, transfer attack success jumps by…

Illustration of the framework of the proposed method. In the first stage, an adversarial image is processed with multiscale analysis: the image will be downsampled by a factor of 1/2 and 1/4, respectively, and upsampled by a factor of 2. Then in the second stage, we design and insert 𝑁 diffusive and denoising aggregation mechanism (DDA) blocks sequentially. Each DDA block involves a diffusive process (Section 3.2), a denoising process (Section 3.3), and an aggregation process (Section 3.4). The output samples from the last DDA block will be inversely processed to the original scale and smoothed to obtain the reversed image.

Reversing Adversarial Attacks on Skin Cancer AI With Multiscale Noise

Skin cancer screening was one of the first places deep learning actually earned its hype. A 2017 Nature paper by Esteva and colleagues showed a convolutional network matching board certified dermatologists at distinguishing benign moles from malignant ones, and the…
