AI, Pizza, and Beer: Wetware vs. AI Software - Pursuit of Ultimate Morse Decoder

  • Jun 11, 2013 · 6:00 PM
  • This location is shown only to members

This month, Mauri Niininen will be discussing his work using probabilistic neural networks to train computers to understand Morse code. Morse code decoding has a long history as a problem in signal processing and remains an active area of statistical/machine learning research.

Mauri Niininen received his M.Sc in Engineering Physics from Helsinki University of Technology (1986). He has a life long interest in computer science and telecommunications and  he works currently as a Director Engineering at Nokia Burlington office.  In the past 5 years he has focused on building cloud services for mobile devices, ramping up operations, service delivery and 24x7 support capabilities globally for Nokia HERE business unit.

He received his first ham radio license in 1976 and served as a voluntary examiner 1981 - 1987 in Finland.  He is holding FCC Extra Class License (AG1LE) since 2010 and is a member of Wellesley Amateur Radio Society. He is also member of the Finnish Amateur Radio League (SRAL) as well as the American Radio Relay League (ARRL).  His current ham radio interests are focused on experiments with Software Defined Radio technology and he is developing Artificial Intelligence methods to improve digital communications, including Morse code.

Join NEAI for presentations and conversations about topics in artificial intelligence followed by study groups and networking. Share your projects, ask for help, help each other, and collaborate/commiserate over pizza and beer.

    It was wonderful to hear about all the work that Mauri has done on his labor of love. Thank you Mauri for the presentation and the engaging conversation afterwards.

    Can you post the two wav files from slide 4 as well?

    Thanks for the opportunity to share my thoughts on Morse decoding problem. I did enjoy fully engaged audience who understood the problems and asked some great questions. Thanks also for your suggestions and all the new ideas. Sorry about the technical problems with the projector. My slides are posted here:

    I didn't realize how effective Morse code was at transmitting messages quickly. I really liked the experiment on the Jay Leno show -- pop culture reference, and I don't normally watch television so hadn't seen it yet.

    Mauri Niininen was fantastic. One of the best technical presentations I've seen at a meetup. Absolutely riveting content and leading edge science. Too bad their were technical problems but that doesn't matter if you are into codes, Morse code, probabilistic neural networks, human (wetware) vs. the state of the art on decoding. Great talk. Thanks.

    Last minute change of plans ... always sorry to miss the NEAI meetup!

    Hey, will there actually be enough pizza for attendees this time? At last weeks' event there was clearly not enough pizza! (Thanks for the beer though...)

    • Dan Von K.

      Probably not.

      June 11, 2013

    • Chad C.

      Yeah, we need a Pizza Fund. We're trying to avoid charging attendees and find a sponsorship that will provide some funds for food.

    Holy crap, I finally remembered my password. Desktop went down, didn't have the pw saved on my work Mac

    And I screwed up the RSVP negation -- daughter leaving for Israel / last minute prep -- sorry have to cancel!!

  • Martin G.

    Sorry!!! Gotta cancel due to last minute help for daughter leaving to teach in Israel for a summer program... !:|

    Sounds like a very interesting topic. I'm looking forward to it.
