摘要
针对可见光图像特征驱动的浮选工况识别方法的不足,提出一种基于双模态图像多尺度CNN特征及自适应深度自编码核极限学习机(Kernel Extreme Learning Machine,KELM)的浮选工况识别方法。先对泡沫的可见光、红外图像进行非下采样剪切波多尺度分解,设计双通道CNN网络对双模态多尺度图像进行特征提取及融合,将多个双隐层自编码极限学习机串联成深度学习网络对CNN特征逐层抽象提取,然后通过核极限学习机映射到更高维空间进行决策,最后改进量子细菌觅食算法并应用于深度自编码KELM识别模型参数优化。实验结果表明采用双模多尺度CNN特征较单模多尺度、双模单尺度CNN特征的识别精度提高了2.65%,自适应深度自编码KELM模型具有较好的分类精度和泛化性能,各工况识别的平均准确率达到95.98%,识别精度和稳定性较现有方法有较大提升。
To address the limitations of visible image feature-driven flotation performance recognition method,a new flotation performance recognition method based on dual-modality multiscale images CNN features and adaptive deep autoencoder kernel extreme learning machine was proposed.First,the visible and infrared images of foam were decomposed by nonsubsampled shearlet multiscale transform,and a two-channel CNN network was developed to extract and fuse the features of the dual-modality multiscale images.Then,the CNN features were abstracted layer-by-layer in the deep learning network,which was connected by a series of two hidden layer autoencoder extreme learning machine.Then,the decision was made by mapping to a higher dimensional space through the kernel extreme learning machine.Finally,the quantum bacterial foraging algorithm was improved and applied to optimize the recognition model parameters.The experimental results show that the recognition accuracy using dual-modality multiscale CNN features is clearly better than that of single modality multiscale and dual-modality single scale CNN features at a confidence level of 2.65%.Further,the adaptive deep autoencoder kernel extreme learning machine has better classification accuracy and generalization performance.The average recognition accuracy of each working condition reaches 95.98%.The accuracy and stability of flotation performance recognition is considerably improved compared with the existing methods.
