Title: Multivariate spatio-temporal Hawkes process models of terrorism
Abstract: We develop a flexible bivariate spatio-temporal Hawkes process model to analyze pat-terns of terrorism. Previous applications of point process methods to political violence data have mainly utilized temporal Hawkes process models, neglecting spatial variation in these attack pat-terns. This limits what can be learned from these models, as any effective counter-terrorism strategy requires knowledge on both when and where attacks are likely to occur. Even the existing work that does exist on spatio-temporal Hawkes processes impose restrictions on the triggering function that are not well-suited for terrorism data. Therefore, we generalize the structure of the spatio-temporal triggering function considerably, allowing for nonseparability, nonstationarity, and cross-triggering(i.e., across the groups). To demonstrate the utility of our model, we analyze two samples of real-world terrorism data: Afghanistan (2002-2013) and Nigeria (2010-2017). Jointly, these two studies demonstrate that our model dramatically outperforms standard Hawkes process models, besting widely-used alternatives in overall model fit and revealing spatio-temporal patterns that are, by construction, masked in these models (e.g., increasing dispersion in cross-triggering over time). This is a joint work with Scott Cook.

Title: Statistical inference for high-dimensional and large-scale data with noisy labels
Abstract: In many classification applications, we are presented with data with partially observed or contaminated labels. One example of such an application is in the analysis of datasets from deep mutational scanning (DMS) experiments in proteomics, which typically do not contain non-functional sequences. In many of these settings, the problem of interest is high-dimensional where the number of features is substantially larger than the sample size. Moreover, the rate of contamination is often unavailable depending on the experimental protocols, which further complicates the downstream analysis. In this talk, I will present both parametric and semi-parametric approaches for analyzing noisy, high-dimensional binary data. I will first demonstrate that when the rate of contamination is available, the noisy label model belongs to a generalized linear model with a non-canonical link, and optimal inference is possible despite the non-convex objective. I will then present a new semi-parametric approach based on hard-thresholding for the analysis of high-dimensional noisy labels data when prior knowledge of the contamination rate is unavailable. Finally, I will present an application of our methodology to inferring sequence-function relationships and designing highly stabilized enzymes based on large-scale DMS data.

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.
