Parallel Experimentation and Competitive Interference on Online Advertising Platforms

Authors: Caio Waisman, Navdeep S. Sahni, Harikesh S. Nair, Xiliang Lin

arXiv

This paper studies the measurement of advertising effects on online platforms when parallel experimentation occurs, that is, when multiple advertisers experiment concurrently. It provides a framework...

TKIL: Tangent Kernel Approach for Class Balanced Incremental Learning

Authors: Jinlin Xiang, Eli Shlizerman

arXiv

When learning new tasks in a sequential manner, deep neural networks tend to forget tasks that they previously learned, a phenomenon called catastrophic forgetting. Class incremental learning methods...

Efficient Penalized Generalized Linear Mixed Models for Variable Selection and Genetic Risk Prediction in High-Dimensional Data

Authors: Julien St-Pierre, Karim Oualkacha, Sahir Rai Bhatnagar

arXiv

Sparse regularized regression methods are now widely used in genome-wide association studies (GWAS) to address the multiple testing burden that limits discovery of potentially important predictors. Li...

The Temporal Evolution of Modality-Independent Representations of Conceptual Categories

Authors: Julien Dirani, Liina Pylkkänen

arXiv

To what extent does language production activate amodal conceptual representations? In picture naming, we view specific exemplars of concepts and then name them with a category label, like 'dog'. In c...

Regression Trees on Grassmann Manifold for Adapting Reduced-Order Models

Authors: Xiao Liu, Xinchao Liu

arXiv

Low dimensional and computationally less expensive Reduced-Order Models (ROMs) have been widely used to capture the dominant behaviors of high-dimensional systems. A ROM can be obtained, using the wel...

A Critical Review of Methods for Real-World Applications to Generalize or Transport Clinical Trial Findings to Target Populations of Interest

Authors: Albee Y. Ling, Maria E. Montez-Rath, Paulo Carita, Karen Chandross, Laurence Lucats, Zhaoling Meng, Bernard Sebastien, Kris Kapphahn, Manisha Desai

arXiv

Generalizability and transportability methods have been proposed to address the external validity bias of randomized clinical trials that results from differences in the distribution of treatment effe...

Some Reflections on Drawing Causal Inference using Textual Data: Parallels Between Human Subjects and Organized Texts

Authors: Bo Zhang, Jiayao Zhang

arXiv

We examine the role of textual data as study units when conducting causal inference by drawing parallels between human subjects and organized texts. %in human population research. We elaborate on key...

Some notes on Goodman's marginal-free correspondence analysis

Authors: Vartan Choulakian

arXiv

In his seminal paper Goodman (1996) introduced marginal-free correspondence analysis; where his principal aim was to reconcile Pearson correlation measure with Yule's association measure in the analys...

Detection and treatment of outliers for multivariate robust loss reserving

Authors: Benjamin Avanzi, Mark Lavender, Greg Taylor, Bernard Wong

arXiv

Traditional techniques for calculating outstanding claim liabilities such as the chain ladder are notoriously at risk of being distorted by outliers in past claims data. Unfortunately, the literature...

Improving Group Testing via Gradient Descent

Authors: Sundara Rajan Srinivasavaradhan, Pavlos Nikolopoulos, Christina Fragouli, Suhas Diggavi

arXiv

We study the problem of group testing with non-identical, independent priors. So far, the pooling strategies that have been proposed in the literature take the following approach: a hand-crafted test...

Family-wise error rate control in Gaussian graphical model selection via Distributionally Robust Optimization

Authors: Chau Tran, Pedro Cisneros-Velarde, Sang-Yun Oh, Alexander Petersen

arXiv

Recently, a special case of precision matrix estimation based on a distributionally robust optimization (DRO) framework has been shown to be equivalent to the graphical lasso. From this formulation, a...

Chronic iEEG recordings and interictal spike rate reveal multiscale temporal modulations in seizure states

Authors: Gabrielle M. Schroeder, Philippa J. Karoly, Matias Maturana, Mariella Panagiotopoulou, Peter N. Taylor, Mark J. Cook, Yujiang Wang

arXiv

Background and Objectives: Many biological processes are modulated by rhythms on circadian and multidien timescales. In focal epilepsy, various seizure features, such as spread and duration, can chang...

Estimating Treatment Effects Using Observational Data and Experimental Data with Non-overlapping Support

Authors: Kevin Han

arXiv

When estimating treatment effects, the golden standard is to conduct a randomized experiment and then contrast outcomes associated with the treatment group and the control group. However, in many case...

Estimating Model Performance on External Samples from Their Limited Statistical Characteristics

Authors: Tal El-Hay, Chen Yanover

arXiv

Methods that address data shifts usually assume full access to multiple datasets. In the healthcare domain, however, privacy-preserving regulations as well as commercial interests limit data availabil...
