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.

Questions

  1. What is time granularity?
    1. The time interval between subsequent observations
    2. The number of missing values in time series data
    3. The number of single entries in time series data
    4. The length of a seasonal pattern
  2. Which of the following is not a purpose of time aggregating data?
    1. To discard redundant information
    2. To discover patterns of interest
    3. To reduce the size of the data
    4. To replace missing values not missing at random
  3. How many observations do you get if you time-align daily data from February 1 to January 1?
    1. Less than 365
    2. More than 365
    3. 365
  4. Which of the following missing values is not missing at random?
    1. Sales data is missing on December 25.
    2. Website traffic data is missing because a log file has been overwritten accidentally.
    3. Temperature data is missing because the thermometer breaks at minus temperatures.
    4. Sales data is missing because the online shop was temporarily closed.
