Researchers have analyzed a networked binary classification system operating on a directed acyclic graph. In this setup, agents sequentially process data, combining local features with predictions from their predecessors. The study proves an upper bound on excess loss for this distributed training method, dependent on network depth and feature observation patterns. It also establishes a lower bound, identifying network depth as a critical constraint for information aggregation in such systems. AI
IMPACT Identifies network depth as a fundamental bottleneck for information aggregation in distributed logistic regression, potentially impacting future distributed training architectures.
