Title: Data Science and Modern Financial Markets
Abstract: Since the celebrated Black-Scholes model emerged in 1973, quantitative approaches in finance have been state-of-the-art tools in financial markets. Recently, development of high frequency markets based on automated and algorithmic trading together with the boom of data science in other areas also led financial industries to adapt to this new trend. In this talk, we discuss briefly the history of quantitative finance, various machine learning tools currently used in financial markets, challenges and promises.
It is disheartening to see the rise of xenophobia and racial intolerance in America in recent years. The difficulties from the pandemic and, more notably, the misinformation and false narratives spread about the COVID-19 virus certainly played a role in exacerbating anti-Asian sentiment and violence in the States. However, we recognize that racism has always been deeply rooted within the US society. The recent tragedy in Atlanta finally brought it to the attention of mainstream media; it is a tragedy and a disgrace to see such hatred on display. Our heartfelt condolences go out to victims' families, relatives and friends as they grieve the loss of their loved ones.
The Korean International Statistical Society (KISS) unequivocally condemns all the violence and discrimination perpetrated against the Asian Americans and Pacific Islanders (AAPI) communities. We remain committed to supporting the AAPI communities, and to working with other professional and scientific societies to cultivate a diverse, inclusive, equitable, and productive environment. We will continue to support our KISS members, our AAPI colleagues, and AAPI students to meet the challenges facing the AAPI communities and our nation.

Title: Statistical Inference after Kernel Ridge Regression Imputation under Item Nonresponse
Abstract: Kernel Ridge Regression (KRR) is a modern regression technique based on the theory of Reproducing Kernel Hilbert Space. We use KRR to develop imputation for handling item nonresponse. While the KRR is potentially promising for imputation, its statistical properties are not fully investigated in the literature. We first establish the root-n consistency of the KRR imputation estimators and show that it is optimal in the sense that it achieves the lower bound of the semiparametric asymptotic variance. A consistent variance estimator is also proposed by a novel application of the KRR estimator of the density ratio function. Results from a limited simulation study are also presented to confirm our theory.
