Unbiased Gradient Boosting Decision Tree with Unbiased Feature Importance
Zheyu Zhang, Tianping Zhang, Jian Li
Gradient Boosting Decision Tree (GBDT) has achieved remarkable success in a wide variety of applications. The split finding algorithm, which determines the tree construction proces…
Less Is More: Fast Multivariate Time Series Forecasting with Light Sampling-oriented MLP Structures
Tianping Zhang, Yizhuo Zhang, Wei Cao +4
Multivariate time series forecasting has seen widely ranging applications in various domains, including finance, traffic, energy, and healthcare. To capture the sophisticated tempo…
Cancellations between Kloosterman sums modulo a prime power with prime arguments
Kui Liu, Igor E. Shparlinski, Tianping Zhang
We obtain a nontrivial bound for cancellations between the Kloosterman sums modulo a large prime power with a prime argument running over very short interval, which in turn is base…
Bilinear Forms with Exponential Sums with Binomials
Kui Liu, Igor E. Shparlinski, Tianping Zhang
We obtain several estimates for bilinear form with exponential sums with binomials . In particular we show the existence of nontrivial cancellations between such su…
Squares in Piatetski--Shapiro Sequences
Kui Liu, Igor E. Shparlinski, Tianping Zhang
We study the distribution of squares in a Piatetski-Shapiro sequence with and . We also study more genera…
