A Unified Framework for Data Poisoning Attack to Graph-based Semi-supervised Learning

2019 · arXiv (Cornell University)

In this paper, we proposed a general framework for data poisoning attacks to graph-based semi-supervised learning (G-SSL). In this framework, we first unify different tasks, goals, and constraints into a single formula for data poisoning …

Enhancing generalization through an optimized sequential curriculum: Learning (to read) through machine teaching.

2020 · eScholarship (California Digital Library)

Learning environments are rich with structure but learning that structure can take considerable effort. Given that thesequence with which knowledge is accumulated is important for development (Smith & Slone, 2017), we consider whetheroptimizing the sequence …
