Listener Gets a VAD
January 21st, 2010 · No Comments · DSP, python
So, the beginning of the 4th semester in the midst of losers and overachievers and this sem promises to set my a$$ on fire. As usual, I plan to continue working under Dr. Kihara this sem so that should be interesting. Anyway, I decided to improve upon what listener offered and decided to add a [...]

During the vacation this summer, I began working on creating an app that would help me respond to calls of attention when my auditory sensory capabilities were compromised courtesy the noise cancellation capabilities of my Bose headsets. Well, I managed to make a few mods to that script, used a touch of applescript (thank god [...]

UPDATE 02/13/2010: Most recent version of this script is now moved to: http://shriphani.com/blog/listener. EDIT: An updated version of this script along with tools to improve the user experience can be obtained at http://shriphani.com/Shriphani_Website/Listener.html After an looooong time, I’ve decided to put finger on keyboard (I think that sounds stupid). Considering that I now use BOSE [...]

Hebb’s Rule
February 9th, 2009 · 4 Comments · College, Computer Science, Mathematics, python
This post is slightly psychology influenced. Well, in the Psychology class I have been taking this semester (Introduction To Cognitive Learning), I was taught about Neural Networks and a certain Hebb’s Rule which allows a network to remember a previous configuration and use this configuration to interpret new information. We use the following model to [...]
