Abstract
Provided are a data clustering apparatus and method, which can rapidly and accurately cluster data. The data clustering apparatus includes an index discriminating unit discriminating an index corresponding to an input position of new data input to a space for data clustering, including a lattice-type segmented space having lattice unit spaces set with different indexes, and a clustering unit creating a new cluster in the discriminated index using the input new data as a representative value when a cluster is not created at the discriminated index.
Claims11
A building energy management apparatus comprising:
- at least one processor configured to execute:
- a receiving unit receiving data from a plurality of sensors installed inside or outside of a building;
- an index discriminating unit discriminating an index (index A) corresponding to an input position of the data, the data being input to a multi-dimensional space for data clustering, including a lattice-type segmented space having lattice unit spaces set with different indexes;
- and
- a clustering unit, when a cluster is not created at the discriminated index (index A), creating a new lattice-type segmented cluster using the data as a representative value of the new cluster, and allowing the data to be included in the new cluster, when a cluster is already created at the discriminated index (index A), allowing the data to be included in a lattice-type segmented cluster already created in a lattice unit space, and changing an old representative value (RVO) of the already created cluster using the data,
- wherein the data is generated by the sensors based on at least one of various kinds of information which the sensors detect, time when the sensors operate, and location where the sensors are installed,
- wherein the clustering unit creates the clusters for clustering the data,
- wherein the building energy management apparatus manages a building energy consumption by using clustering results of the clustering unit,
- wherein the index discriminating unit discriminates an index of the data using a value obtained by dividing a difference between the data and a minimum value among values positioned in the lattice-type segmented space by a difference between a maximum value among values positioned in the lattice-type segmented space and the minimum value among values positioned in the lattice-type segmented space, and then multiplying a divided result with an inverse number of a total number of different indexes set to each of the lattice unit spaces.
