specific Embodiment approach

[0029]The specific implementation method is as follows. Firstly, the OneVSall algorithm based on logistic regression is adopted. This algorithm regards a current class as one class and all other classes as one class. This is actually a binary classification problem. After this class is separated, this algorithm is used here for all other classes, so that multiple classifications can be performed to achieve multi-classification problems. In logistic regression, the loss function used is as follows:

[0030]

[0031]

[0032] Where J(θ) is the loss function, θ is the model parameter vector, m is the number of training samples, x (i) Represents the i-th training sample, y (i) Represents the label corresponding to the i-th training sample, h θ (x) is the activation function.

[0033] After the style classification, the music beat is extracted, and some beat points that do not need to be changed are eliminated according to the energy change of the music, and the time point...

Abstract

The invention relates to a music fountain simulation system based on OpenGL. The system is characterized by comprising a music feature extraction unit which carries out feature extraction of music, and selects a proper feature vector to represent a song; a music characteristic signal fusion unit; a music fountain simulation software background which uses a particle system based on OpenGL; a musicfountain control foreground. Software on the market at present is software based on specific music, and picture making is very simple; however, the OpenGL is used for background design in the invention, fountain effect is simulated, and an interface is provided for the outside to allow a user to call the fountain effect. A music analysis part is introduced into the whole system, so the characteristics of newly added music can be analyzed, and actions can be selected and displayed according to characteristic parameters.

Description

technical field [0001] The invention belongs to the field of music signal analysis and simulation, in particular to a music fountain simulation system based on OpenGL simulation technology. Background technique [0002] With the progress of society, people's requirements for living environment are getting higher and higher. Due to the changeable shape of the water landscape and the combination of rigidity and softness, the waterscape has become particularly important for the decoration of urban public spaces. A large pool can effectively enhance the sense of space. If sprinklers are placed in it to form a fountain, it can make the space full of dynamic beauty, make the landscape more lively, and add the charm of the urban landscape. [0003] Fountains are a special means of reproducing nature in an urban environment. The combination of artistic design and fountain design can restore the feeling of nature. The artistic design of the shape, sound and color of the fountain c...
