Artificial intelligence-based composing method and system, computer device and storage medium

Abstract

The invention discloses an artificial intelligence-based composing method and system, a computer device and a storage medium, wherein the method comprises the following steps: obtaining note information, wherein the note information comprises a playing start time, a playing duration time and a pitch value of each note; creating a music time sequence, and performing autoregressive integral moving average ARIMA model prediction to obtain a time sequence prediction result; constructing a music prediction model according to the note information and the time sequence prediction result; determininga topological structure of a music prediction model, and obtaining and realizing automatic composition predicted music, according to the note information and the time sequence prediction result, combining the music prediction model and the determined topological structure. The method realizes automatic composition, greatly simplifies the production process, allows users to participate in the creation, generates different tracks through different inputs, does not require midway intervention, and is flexible and rich.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to an artificial intelligence-based composition method, system, computer equipment and storage medium. Background technique [0002] With the application of computer technology in music processing, computer music came into being. As a new generation of art, computer music has gradually penetrated into music creation, musical instrument performance, education, entertainment and other aspects. Using artificial intelligence technology to automatically compose music is a relatively new research direction in computer music. In recent years, it has been favored by researchers in related fields. of great importance. [0003] The existing automatic composition methods based on artificial intelligence technology mainly include automatic composition based on heuristic search and automatic composition based on genetic algorithm. However, the existing automatic composition based ...

AI Technical Summary

Problems solved by technology

However, the existing automatic composition based on heuristic search is only suitable for the short length of the music, and its search efficiency decreases exponentially with the increase of the length of the music, so the feasibility of this method is poor for longer music

However, the automatic composition method based on the genetic algorithm inherits some typical shortcomings of the genetic algorithm, such as a large dependence on the initial population, difficulty in selecting genetic operators accurately, etc.
