    •  NEWS   MERL Researchers Demonstrate New Model-Based AI Learning Technology for Equipment Control
      Date: February 14, 2018
      Where: Tokyo, Japan
      MERL Contacts: Devesh Jha; Daniel Nikovski; Diego Romeres; William Yerazunis; Jeroen van Baar; Alan Sullivan
      Research Areas: Optimization, Computer Vision, Data Analytics, Robotics
      Brief
      • New technology for model-based AI learning for equipment control was demonstrated by MERL researchers at a recent press release event in Tokyo. The AI learning method constructs predictive models of the equipment through repeated trial and error, and then learns control rules based on these models. The new technology is expected to significantly reduce the cost and time needed to develop control programs in the future. Please see the link below for the full text of the Mitsubishi Electric press release.

    •  NEWS   MERL researcher's spam filter finds automobile safety defects at NHTSA
      Date: June 25, 2015
      MERL Contact: William Yerazunis
      Research Area: Data Analytics
      Brief
      • The CRM114 Discriminator, an open-source spam filter / text classifier created by William Yerazunis in MERL's Data Analytics group, continues to turn up in interesting places - and apparently one of them is in the US Department of Transportation's process for analysis of car safety defect reports.

        Although CRM114 is usually used as a spam filter, CRM114 has been used to analyze resumes for jobseekers, scanning outgoing emails to detect accidental confidential information leaks, perusing blogs for relevance, scanning syslog files for interesting events, and now, apparently, searching complaints sent to NHTSA to find safety-related vehicle malfunctions.
