Upcoming lecture by Raja Appuswamy, Postdoctoral Researcger in the DIAS lab at EPFL, on data management systems Abstract The design of data management systems has always been driven based on two aspects, namely, underlying hardware and applications requirements. The past few years have, however, witnessed dramatic changes in both these aspects. On the hardware front,... Read more »

HiPEDS CDT Seminar Series with Giorgio Orsi, Senior Research Scientist at Meltwater. Abstract: Data acquisition plays an important role in modern organisations and is a strategic business process for data-driven companies such as insurers, retailers, and search engines. Data acquisition processes range from manual data collection and purchase, to cheaper but often technically challenging methods... Read more »

Abstract: In 1987, Jim Gray and Gianfranco Putzolu introduced the five-minute rule for trading memory to reduce disk I/O using the then-current price-performance characteristics of DRAM and Hard Disk Drives (HDD). Since then, the five-minute rule has gained wide-spread acceptance as an important rule-of-thumb in data engineering. In the first part of this talk, we... Read more »

Abstract: Formal verification of software has finally started to become viable: we have examples of formally verified microkernels, realistic compilers, hypervisors etc. These are huge achievements and we can expect to see even more impressive results in the future but the correctness proofs depend on a number of assumptions about the Trusted Computing Base that...

Abstract: Large technology companies rely on collecting data from their users to understand their interests, and better customize the company's products. Increasingly, this must be done while preserving individual users' privacy.  Recently, techniques based on radomization and data sketching have been adopted to provide data collection protocols which optimize the privacy accuracy trade-off.  In this talk, I'll...
