Machine learning algorithms analyze mobile phone data for Parkinson’s research

The Michael J. Fox Foundation is exploring how data sourced from mobile phones and analyzed with machine learning algorithms can improve Parkinson’s research.  The research was crowdsourced via a public competition.

The initial study included 16 individuals — nine patients, seven control.  For 8 weeks, 4-5 hours per day, each carried a smartphone with seven sensors collecting data. Inputs of a built-in accelerometer, data about the user’s tone of voice, how much the phone was turned on and used, data from the built-in compass and GPS, and an ambient light sensor were analyzed. A machine learning algorithm was developed to use the data to identify the Parkinson’s patients from the control group and identify what stage of the disease users were in.

  1. I’m truly enjoying the design and layout of your website.
    It’s a very easy on the eyes which makes it much more enjoyable
    for me to come here and visit more often. Did you hire out a
    developer to create your theme? Fantastic work!

  2. Link exchange is nothing else but it is only placing the other person’s website link on your page at suitable place and other person
    will also do same in support of you.

  3. Fantastic website you have here but I was wondering if you knew of
    any message boards that cover the same topics discussed in this
    article? I’d really love to be a part of group where I
    can get comments from other knowledgeable people that share the same interest.
    If you have any suggestions, please let me know.
    Many thanks!

  4. This design is spectacular! You obviously know how to keep
    a reader amused. Between your wit and your videos,
    I was almost moved to start my own blog (well, almost…HaHa!)
    Wonderful job. I really loved what you had to say, and more than
    that, how you presented it. Too cool!

  5. I’m not sure why but this web site is loading extremely slow for me.
    Is anyone else having this problem or is it a problem on my end?

    I’ll check back later and see if the problem still exists.
