Work is starting to get pretty messy with EvoSpeak. I'm trying to design a very generalized analysis framework to allow easy analysis of just about any relationship. Doing so is not at all easy. My strategy is to set up a "perception" matrix that simulates the state of any given sample at any given point in time. The idea is that an analysis function can build a filter matrix and then call the perception function, which will subsequently compare the filter matrix to the perception matrix and gather appropriate statistics.

The first analysis to be implement is, of course, a zeroeth-order Markov. Fancy language aside, what it boils down to is this: did the species use a certain word (melodic or rhythmic) in a certain sample? So a zeroeth-order Markov simply deals with the innate "quality" of certain words over other words, not taking into account ANY contextual variables.

Problems arise quickly with this general framework. It's very difficult to obtain certain state values to populate the matrix because of the grammar engine design. The melodic and rhythmic data streams are asynchronous, so melodic events don't necessarily line up with rhythmic events, which makes finding synchronous data (like perception data) very difficult. Apparently, I've already messed up in trying to separate the streams, as indicated by the presence of some anomalies in the preliminary statistics.

On top of all that, the analysis is a LOT slower than I thought it would be, even after serious reconstruction and optimization. I knew that it would take a lot of loops and recursions to do the analysis...but I thought the computer would just chew through them. Already a simple zeroeth-order Markov analysis on the melody alone costs about 2.6 seconds. Using that number and performing the necessary exponential extrapolating, a second-order Markov analysis would take a whopping sixteen minutes, which is simply unacceptable. And that's only to level-up once. I'm definitely going to have to figure something out there.

While I'm running into some obstacles, EvoSpeak is still advancing steadily and I'm confident that the analysis functions will soon be fully-functional.
