CBE: A Complexity-adaptive Boundary-aware Ensemble Method for Imbalanced Data

Read the original on Hugging Face Trending Papers →

The paper introduces CBE, a complexity‑adaptive boundary‑aware ensemble method designed to handle class imbalance in classification tasks. It links sampling weights to data complexity, dynamically adjusting boundary preference during under‑sampling, and employs a multi‑level complexity measure to categorize datasets into Easy, Median, and Hard. Experiments on 24 UCI and KEEL datasets show that CBE improves F‑measure and G‑mean on Easy and Median cases without harming performance on Hard cases.

Tabular Imbalanced Learning: A Survey, Benchmark, and Practical Guide

The paper surveys tabular imbalanced learning and introduces TILBench, a benchmark evaluating over 40 methods on 57 datasets. It presents a unified taxonomy of approaches and shows that no single method dominates across all settings, with performance depending on dataset regimes and computational constraints. Practical recommendations for method selection and future research directions are provided.

Rethinking Data Selection: The Importance of Coverage over Difficulty in LLM Fine-Tuning

The paper argues that for fine‑tuning large language models, selecting training data based on coverage of the input space is more effective than selecting based on difficulty. While difficulty‑based scores work for smaller classification models, they often underperform random sampling for LLMs. The authors propose a simple clustering‑based method that improves coverage and achieves performance equal to or better than random selection, especially on multi‑domain tasks.
