A Leap from Model-Centric to Data Centric AI

Data Science, Machine Learning

Data as a major component of a deep learning solution is often undervalued in the ML projects, which results in a lower-than-expected accuracy, requiring hours and hours of model tuning. According to Andrew Ng, 99% of the recent publications are model-centric with only 1% being data-centric. He argues that there should be a balance between […]

Robust Query Processing: A Case for Geometric Techniques

Query Processing

INTRODUCTION Over the last half-century, the design and implementation of declarative query processing techniques in relational database systems has been a foundational topic for both the academic and industrial database research communities. Despite this sustained study, the unfortunate reality is that the resulting solutions have largely remained a “black art”. This is due to the […]

Natural Language-Based Exploration with Databases in Chatbot

Databots

We expect virtually every database to be on Cloud shortly. All database vendors strive to survive in this competing market. In the era of cloud computing, databases will become easily accessible, and thus even non-technical users want to use such databases like their TVs. In this situation, we need to interact with databases through accessible […]

Data Science for Social Good: the STAR Mission

Data Science, Social Good

Data Science for Social Good, or DSSG, broadly refers to the use of data engineering and analysis solutions in the social work domain.  I am interested in this field, because it gives me a chance to understand how database technologies can be used in a domain whose data-driven approaches are only in its infancy. Moreover, […]
