I thoroughly enjoyed today’s lecture and it got my mind thinking. When you think about it noise is usually just the background sound that we don’t pay any attention to it’s the sound that is distracting us from what we are doing. As humans we are always looking for signs and “signals” to let us know that its time to do something or somethings happening, etc. The example that Professor O’Malley provided in class really helped me to grasp the signal and noise concept. The example was when we go to ask or mom or parents a question and mom doesn’t give us an answer she just starts to lecture. The question would be a signal and the lecture is noise. It is the difference between what we want to hear and what we don’t want, which would just be noise. I’ve always thought that as people with higher education we shouldn’t think of questions only with a yes or no answer, but like you said in class any problem can be reduced to a yes no question. It just makes everything more simple and is a less complicated way to answer a question. The one thing that I am still having a hard time understanding from class is the concept of information being related to uncertainty and the more uncertainty, the more information. The U and Q example didn’t help me understand this at all either. I guess my brain can’t grasp on to this concept. Overall I really enjoyed the lecture on signal to noise ratio.
