Alpha Mining and Enhancing via Warm Start Genetic Programming for Quantitative Investment
Weizhe Ren, Yichen Qin, Yang Li
Traditional genetic programming (GP) often struggles in stock alpha factor discovery due to its vast search space, overwhelming computational burden, and sporadic effective alphas.…
Adaptive Weighted Random Isolation (AWRI): a simple design to estimate causal effects under network interference
Changhao Shi, Haoyu Yang, Yichen Qin +1
Recently, causal inference under interference has gained increasing attention in the literature. In this paper, we focus on randomized designs for estimating the total treatment ef…
Assessing Estimation Uncertainty under Model Misspecification
Rong Li, Yichen Qin, Yang Li
Model misspecification is ubiquitous in data analysis because the data-generating process is often complex and mathematically intractable. Therefore, assessing estimation uncertain…
Irregular Hodge filtration of hypergeometric differential equations
Yichen Qin, Daxin Xu
Fedorov and Sabbah--Yu calculated the (irregular) Hodge numbers of hypergeometric connections. In this paper, we study the irregular Hodge filtrations on hypergeometric connections…
-functions of Kloosterman sheaves
Yichen Qin
In this article, we study a family of motives associated with the symmetric power of Kloosterman sheaves, as constructed by Fresán, Sabbah, and Yu. They demons…
Optimal integrating learning for split questionnaire design type data
Cunjie Lin, Jingfu Peng, Yichen Qin +2
In the era of data science, it is common to encounter data with different subsets of variables obtained for different cases. An example is the split questionnaire design (SQD), whi…
