This document summarizes a presentation about analyzing NYC taxi data using Hive and machine learning. It discusses ingesting 18.7 GB of taxi data into an HDInsight Hadoop cluster, querying the data using Hive, visualizing it with Power BI, and using Azure Machine Learning to build predictive models with algorithms like logistic regression and boosted decision trees to predict metrics like payment type, tip amount, and whether a tip was given based on the taxi data. It provides references and source code links and demonstrates evaluating models and comparing different predictions.
