谱聚类算法建立在谱图理论基础上,与传统的聚类算法相比,它具有能在任意形状的样本空间上聚类且收敛于全局最优解的优点。 该算法首先根据给定的样本数据集定义一个描述成对数据点相似度的亲合矩阵,并且计算矩阵的特征值和特征向量 , 然后选择合适 的特征向量聚类不同的数据点。谱聚类算法最初用于计算机视觉 、VLS I 设计等领域, 最近才开始用于机器学习中,并迅速成为国际上机器学习领域的研究热点。-Spectral clustering algorithm based on the spectrum based on the theory, as compared with traditional clustering algorithm, which has the advantage of clustering and convergence in the sample space to the global optimal solution of arbitrary shape. Firstly, according to the given sample data set defines a description paired data points of similarity affinity matrix, and compute eigenvalues and eigenvectors, and then the appropriate feature vector clustering of different data points. Spectral clustering algorithm was originally used in computer vision, VLS I design and other fields, only recently began to be used in machine learning, and quickly became the focus of international research on the field of machine learning.

深度学习的概念源于人工神经网络的研究。含多隐层的多层感知器就是一种深度学习结构。深度学习通过组合低层特征形成更加抽象的高层表示属性类别或特征,以发现数据的分布式特征表示。[1] 深度学习的概念由Hinton等人于2006年提出。基于深信度网(DBN)提出非监督贪心逐层训练算法,为解决深层结构相关的优化难题带来希望,随后提出多层自动编码器深层结构。此外Lecun等人提出的卷积神经网络是第一个真正多层结构学习算法,它利用空间相对关系减少参数数目以提高训练性能。[1] 深度学习是机器学习研究中的一个新的领域,其动机在于建立、模拟人脑进行分析学习的神经网络,它模仿人脑的机制来解释数据,例如图像,声音和文本。 同机器学习方法一样,深度机器学习方法也有监督学习与无监督学习之分.不同的学习框架下建立的学习模型很是不同.例如,卷积神经网络(Convolutional neural networks,简称CNNs)就是一种深度的监督学习下的机器学习模型,而深度置信网(Deep Belief Nets,简称DBNs)就是一种无监督学习下的机器学习模型。 -Research on the concept of deep learning the artificial neural network. Multi hidden layer of multi-layer perceptron is a deep learning structure. Deep learning features a more abstract representation of a higher level representation of a feature class or feature to find data. [1] Deep learning s concept by Hinton et al. In 2006. Based on the (DBN), a non supervised greedy layer by layer training algorithm is proposed to solve the problems of the deep structure. In addition, the convolutional neural network proposed by Lecun et al is the first real multi layer structure learning algorithm, which uses the relative relationship between the number of parameters to improve the training performance. [1] Deep learning is a new field in machine learning research. The motivation is to establish and simulate the human brain to analyze the learning of neural network, which simulates the human brain mechanism to explain the data, such as image, sound and text.

Just like EM of Gaussian Mixture Model, this is the EM algorithm for fitting Bernoulli Mixture Model. GMM is useful for clustering real value data. However, for binary data (such as bag of word feature) Bernoulli Mixture is more suitable.
