Ari’s Week 4 Status Report

This week I began testing our training data and the data that we are getting from our microphone. I performed cosine similarity on the frequency magnitude of the two sound files and found that their frequency spectrum are nearly identical with a cosine similarity of .87. I also began to determine our testing and validation setup to try to mimic a human heart. I found that we would not need a gel and that playing the sounds through a speaker would be sufficient.
