Codeless Time Series Analysis with KNIME

By: KNIME AG, Corey Weisinger, Maarit Widmann, Daniele Tonini

Overview of this book

This book will take you on a practical journey, teaching you how to implement solutions for many use cases involving time series analysis techniques. This learning journey is organized in a crescendo of difficulty, starting from the easiest yet effective techniques applied to weather forecasting, then introducing ARIMA and its variations, moving on to machine learning for audio signal classification, training deep learning architectures to predict glucose levels and electrical energy demand, and ending with an approach to anomaly detection in IoT. There’s no time series analysis book without a solution for stock price predictions and you’ll find this use case at the end of the book, together with a few more demand prediction use cases that rely on the integration of KNIME Analytics Platform and other external tools. By the end of this time series book, you’ll have learned about popular time series analysis techniques and algorithms, KNIME Analytics Platform, its time series extension, and how to apply both to common use cases.

    1. You can build custom ensemble models.
    2. You can process data faster.
    3. You can access data from online data sources.
    4. You can write custom scripts.
  2. Which of the following characteristics best describes stock market data?
    1. Regular patterns
    2. Rapid changes
    3. Many missing values
    4. Always multivariate
  3. How can you perform feature selection on H2O?
    1. By connecting the H2O Partitioning node directly to the Feature Selection Loop Start node
    2. Using the H2O Feature Selection loop nodes
    3. By converting the data into an H2O data frame at the start of the loop body
    4. By checking the feature importance statistics of the H2O generalized linear model
  4. How can you adapt the application to execute an H2O Random Forest regression model instead?
    1. By switching all learner nodes to H2O Random Forest Learner (Regression) nodes in the model training workflow
    2. By switching all learner and predictor nodes to H2O Random...
