1. Basic knowledge of LDALDA (latent Dirichlet Allocation) is a thematic model. LDA a three-layer Bayesian probabilistic model that contains the word, subject, and document three-layer structures.LDA is a build model that can be used to generate a document that, when generated, chooses a topic based on a probability, then a word in the subject of probability selection, so that a document can be generated, and in turn, LDA is an unsupervised machine

Cross-validation
method thought:
Crossvalidator divides the dataset into several subsets for training and testing respectively. When K=3, Crossvalidator produces 3 training data and test data pairs, each data is trained with 2/3 of the data, and 1/3 of the data is tested. For a specific set of parameter tables, Crossvalidator calculates the average of the evaluation criteria for the training model based on three sets of different training data and test data. After the optimal parameter table is
