Ensemble learning for credit risk classification: a large-scale empirical study

Xing Liu

To address challenges of high dimensionality, nonlinearity, and sample imbalance in large-scale binary classification, a comprehensive ensemble learning framework is proposed. XGBoost, Random Forest, and Logistic Regression are selected as base models. After five-fold cross-validation and Bayesian optimization for hyperparameter tuning are …

A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation

Shao-Yu Fu, Cui-Yuan Dai, Ailing Wang, Dong Xu et autres

Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However, for more than half of the EFXTs, their physical origins remain elusive. In this Letter, we report the …

Sensitive determination of biologically important transition metals by ICP-QMS using micro-ultrasonic single droplet nebulization

Yang Yu, Junhang Dong, 钟宝亮, Xiaoqing Jin et autres

A MUSDN-ICP-QMS method allows direct analysis of trace elements in undigested serum using only 1–5 µL per test. It exhibits high TDS/organic tolerance and one order of magnitude higher sensitivity than conventional PN-ICP-QMS.
