项目介绍
数字化时代带动着整个社会的信息化发展随着数字媒体的不断发展现在通多媒体数字产品的内容越来越丰富传播影响力越来越强以音乐为例现在的音乐文化多样、音乐资源也异常的丰富在这种大数据的环境下人们要想找到想要的音乐类型、找到心里所想的那首音乐无疑是大海捞针。现在音乐的推荐系统也非常的多但是推荐的内容、推荐的方式却与用户的感知差距明显或多或少都会存在一些问题。而随着深度学习、卷积神经网络的不断发展现在的深度学习在图像识别、自然语言等领域都有着很好的发展也很好的应用在了音乐的推荐过程中。
本次的研究是基于使用自动编码器通过与卷积神经网络相结合以挖掘音频、歌词本身的非线性特征来实现很好的音乐推荐、音乐查找识别的功能实现并将内容特征与协同过滤共同作用训练紧耦合模型。通过此次的系统搭建与开发能够通过深度学习的方式让系统可以实现按照用于的喜好来进行音乐的推荐的功能实现。
