Data-quality Driven Design of Databases

Big Data, Databases No Comment

Financially, poor data quality costs organizations some ludicrous amounts of money. Worse, poor data quality is a strong inhibitor to the success of data science: No analytical method can create value from poor quality data. As a consequence, data science projects invest a majority of their resources on cleansing data. However, cleansing resists automation as […]

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 […]
