Data Science Jobs

Data science, which should not be mistaken for information science, is a field of study that uses scientific processes, methods, systems, and algorithms to extract insights and knowledge from various forms of data, be it structured or unstructured. It is similar to data mining and is a conception to unify machine learning, data analysis, statistics, and their related methods so as to analyze and understand the actual facts about data. Data science employs theories and techniques taken from many disciplines such as computer science, information science, statistics, and mathematics.

In a nutshell, data science can be said to be a multidisciplinary blend of algorithm development, data inference, and technology in a way to find solution to analytically complex problems. Data science is useful to anyone who wants to be a data miner.

    Social media users generate tremendous amounts of data. To better serve users, it is required to share the user-related data among researchers, advertisers and application developers. Publishing such data would raise more concerns on user privacy. To encourage data sharing and mitigate user privacy concerns, a number of anonymization and de-anonymization algorithms have been developed to help protect privacy of social media users. In this work, we propose a new adversarial attack specialized for social media data. We further provide a principled way to assess effectiveness of anonymizing different aspects of social media data. Our work sheds light on new privacy risks in social media data due to innate heterogeneity of user-generated data which require striking balance between sharing u...

    Background: The fourth of our eight great ideas is Performance via Parallelism, and for many years we have exploited Instruction Level Parallelism (ILP) in implementing the fifth great idea, Performance via Pipelining. Much effort was placed on identifying, exposing, and exploiting ILP, including techniques for finding ILP that might not have been directly visible by cursory examination of the code. This effort was so effective that pipelines remain pretty much universal in modern general purpose computers. While we recognize the importance of modern pipelines, some people believe that we have reached the limit in exploitation of ILP, and we have turned to other types of parallelism to further enhance performance. These other types of parallelism are the focus of this paper. Paper: For...

    A consumer bank with a range of products would like to cross-sell insurance to its consumer base (that is, cross-sell the personal protection insurance (PPI) product to those customers who have a secured or unsecured type of loan, but no PPI product as yet). Attached is a sample data set from their customer portfolio containing various fields about their product ownership, credit standing, outstanding amounts, and whether they already have an insurance product (called as PPI / personal protection insurance), if any, the type of PPI product they own. The bank would like to adopt analytics driven approach applied on this sample data for deciding: - Who should they target from the pool of customers that currently do not have a PPI, and - What type of PPI product they should be targeting the...
