Learn all you need to know about BigML's implementation of Latent Dirichlet Allocation (LDA), one of the most popular probabilistic methods for topic modeling. Topic Models, BigML's latest resource, helps you find relevant terms thematically related in your unstructured text data. With the BigML Topic Models in your Dashboard and in the BigML API, you will be able to discover the hidden topics in your text fields and use them as final output for information retrieval tasks, collaborative filtering, or for assessing document similarity, among others. You can also use the topics discovered as input features to train other models.
