A faculty affiliate of the CS Department, Venkatasubramanian synthesizes concepts from economics, political philosophy, game theory, statistical mechanics, and systems engineering into a quantitative theory for maximizing fairness in free-market capitalism.
“The Role of Conversation Context for Sarcasm Detection in Online Interactions” considers the larger context of online conversations to accurately detect sarcasm while also identifying what triggered a sarcastic reply.
For decades, devicemakers, engineers, and others have been able to count on a new generation of chips coming to market, … Continue reading Luca Carloni on the coming engineering renaissance in chip design
Last week in Stockholm, Columbia researchers presented three papers at Interspeech, the largest and most comprehensive conference on the science … Continue reading Columbia speech researchers present four papers in August
Interactive Robogami, an MIT CSAIL project, lets anyone design a robot in minutes, and 3D-print and assemble it in as little as four hours. A key feature is controlling a robot’s gait and geometry.
The paper, by three Columbia researchers, describes CLKSCREW, a new class of fault attacks that exploit the security-obliviousness of energy management mechanisms. The attack does not require physical access to devices or fault injection equipment.
In a paper published in PNAS, they call for a holistic approach to data science, one that weaves statistics and computer science into a larger framework while considering context and responsibilities when using data. Subscription.
The Winner’s Curse—where newly discovered genetic effects are consistently overestimated and fail consistently to replicate in subsequent studies—afflicts every genome-wide … Continue reading Genome-wide association studies, minus the Winner’s Curse, are shown to be reliable and replicable
Eitan Grinspun and Changxi Zheng worked with MIT researchers to create InstantCAD, a plugin providing real-time feedback on how design changes affect performance. A paper describing InstantCAD will be presented at SIGGRAPH in August.
When 108,000 students enrolled in her inaugural online edX artificial intelligence course, Ansaf Salleb-Aouissi and two assistants divided up among … Continue reading Ansaf Salleb-Aouissi receives provost award to build MOOC chatbot
In a DARPA project, researchers are looking to build a less invasive implant device at the scale of 1M channels. Such a device would dramatically expand ways artificial systems can support brain functions.
“Settling the query complexity of non-adaptive junta testing” was named best paper at last week’s 32nd Computational Complexity Conference (CCC), … Continue reading Paper by Columbia researchers named best paper at Computational Complexity Conference
Hirschberg’s subject was entrainment, the tendency of speakers to align their speaking style with that of a conversation partner. Joint work with Štefan Beňuš, Nishmar Cestero, Agustín Gravano, Rivka Levitan, Sarah Ita Levitan, Zhihua Xia.
When data can be anywhere, what country has jurisdiction? In a case involving an Outlook user—whose data was stored in Ireland by a US company (Microsoft)—a US court will rule on what country’s laws apply.
How best to efficiently search for similar items in a large dataset? In this Simons Foundation talk, Alexandr Andoni describes using the tools and perspectives of high-dimensional geometry to benefit search algorithms.
