Center node: "rae the rainforest automation energy dataset for smart grid meter data analysis"
  Abstract: Datasets are important for researchers to build models and test how well their machine learning algorithms perform. This paper presents the Rainforest Automation Energy (RAE) dataset to help smart grid researchers test their algorithms that make use of smart meter data. This initial release of RAE contains 1 Hz data (mains and sub-meters) from two residential houses. In addition to power data, environmental and sensor data from the house’s thermostat is included. Sub-meter data from one of the houses includes heat pump and rental suite captures, which is of interest to power utilities. We also show an energy breakdown of each house and show (by example) how RAE can be used to test non-intrusive load monitoring (NILM) algorithms.

Connected through hyperedge HE-1 (induced by source paper "a generative model for non intrusive load monitoring in commercial buildings"):

    - "non intrusive energy disaggregation using non negative matrix factorization with sum to k constraint"
    - "cooll controlled on off loads library a public dataset of high sampled electrical signals for appliance identification"
    - "non intrusive load monitoring a review and outlook"
    - "a comparison of non intrusive load monitoring methods for commercial and residential buildings"
