Title:

Modern AI for Age-old problems of Database Systems

Abstract:

Modern deep learning methods are pushing the frontiers of many challenging problems in database systems. We will discuss state-of-the-art machine learning models that are providing record breaking accuracies on age-old tasks such as entity resolution, missing value imputation and natural language querying. We are also witnessing brand new capabilities that were not possible a few years back. We can perform entity resolution across heterogeneous, multilingual datasets via actively learned nearest neighbor indices, thereby eliminating the need for hand-designing blocking predicates. On multi-dimensional analytical datasets, we can now obtain joint distributions over thousands of interacting time series. Advances in pre-trained language models have significantly increased the capability of handling natural variations in parsing text input to SQL. In this talk we will go over the latest ML research that is enabling these capabilities, and present directions for future research.

Title:

openGauss: An Autonomous Database System

Abstract:

In this talk, I will present how to build an autonomous database system. I discuss how to integrate effective learning-based models into database systems to build learned optimizers (including learned query rewrite, learned cost/cardinality estimation, learned join order selection and physical operator selection) and learned database advisors (including self-monitoring, self-diagnosis, self-configuration, and self- optimization). I also propose an effective validation model to validate the effectiveness of learned models. I discuss effective training data management and model management platforms to easily deploy learned models. Finally I will introduce our autonomous database system openGauss.

Title:

Fairness in Database Querying

Abstract:

We are being constantly judged by automated decision systems that have been criticized for being sometimes discriminatory and unfair. In this talk, we focus on fairness issues that arise when users perform ad-hoc exploration of databases using commonly available querying mechanisms such as selection/range queries, ranking queries, top-k queries, etc. For example, a user may use such queries to retrieve suitable employment opportunities in a jobs database, dating partners in a matching website, or apartments to rent in a real estate database. We will discuss how such querying mechanisms can give sometimes give results that are discriminatory, and discuss approaches to detect, mitigate and prevent such scenarios from occurring. Our work represents some of the initial steps towards the broader goal of integrating fairness conditions into database query processing and data management.

Title:

Teasing journalistic findings out of heterogeneous sources: a data/AI journey

Abstract:

Freedom of the press is under thread worldwide, and the quality of information that people have access to is dangerously degraded, under the joint threat of non-democratic governments and fake information propagation. The press as an industry needs powerful data management tools to help them interpret the complex reality surrounding us.

Since 2018, I have been cooperating with journalists from Le Monde, France's leading newspaper, in devising tools for analyzing large and heterogeneuos data sources that they are interested in. This research has been embodied in ConnectionLens, a graph ETL tool capable of ingesting heterogeneous data sources into a graph, enriched (with the help of ML methods) with entities extracted from data of any type. On such integrated graphs, we devised novel algorithms for keyword search, and combine them in more recent research with structured querying. The talk describes the architecture and main algorithmic challenges in building and exploiting ConnectionLens graphs, illustrated in particular on an application where we study conflicts of interest in the biomedical domain. This is joint work with A. Anadiotis, O. Balalau, H. Galhardas and many others. ConnectionLens Web site (papers+code): https://team.inria.fr/cedar/connectionlens/

Title:

Oracle Database In-Memory: The Enterprise, at Warp Speed !

Abstract:

In-memory computing is more than simply about speed. It enables a fundamental transformation in business processes. Just as air travel enabled more than just the ability to travel faster: It enabled a completely new global economy, reshaped politics, and transformed society. Oracle's Database In-Memory feature similarly enables not just faster analytics, but a fundamental rethinking and drastic simplification of the traditional analytic platform. Combined with Oracle's many converged database capabilities that bring together many data models and many workloads, and with Oracle's Autonomous Database platform that makes self-driving machine-learning powered databases a reality, Oracle Database In-Memory allows for the development of a new category of enterprise architectures, with significant reduction in cost and complexity, while providing unmatched performance for both transactional and analytic workloads.
