[Draft] Automatic Ringtone Generator

This is a draft of some preliminary ideas and thoughts developed in the past few years. The concept is not yet complete nor solid, so for people who are interested, please feel free to leave comments.

[Intro]
The central concept of the proposed system is a mapping mechanism between different types of sequences. The mapping doesn't have to be two-way, nor definite (incomplete transform, mathematically speaking).  The system in design transforms the personal information (PI, in vCard format) into melodies (M, in symbolic forms), in format that can serve as ringtones on various devices (general MIDI or ABC format).

Most media-playback functionalities are included in the application layer of mobile OS's.  To complete the system, two additional libraries are required, they are, (1) a kernel which maps the PI to M, and (2) a library that translate the symbolic form of M into playable audio format.  There have been publicly available candidates for (2), and the design of (1), including its training method, is the core of this system.

Further details will be written in a more formal document.
