Abstract: Inspired by sparse learning, the Markowitz mean-variance model with a sparse regularization term is popularly used in sparse portfolio optimization. However, in penalty-based portfolio ...

Cardinality estimation (CE) is essential to many database-related tasks, such as query generation, cost estimation, and query optimization. Accurate CE is necessary to ensure optimal query planning ...

Abstract: We describe an intuitive and practically significant empirical phenomenon that relates to the concept of cardinality of a fuzzy set, namely, an excessive accumulation of small degrees of ...

Cardinality estimation is widely believed to be one of the most important causes of poor query plans. Prior studies evaluate the impact of cardinality estimation on plan quality on a set of ...

What is the largest natural number possible? By using the word natural, I have ruled out the possibility that you simply answer infinity (∞) to torpedo the guessing game. But even if we allowed ...

Recent learned cardinality estimation (CE) models are vulnerable when query predicates or the underlying datasets drift from what the models were trained upon. We propose a system Warper that ...
