__%%( color: #003399; font-size: 30px;)Exploratory Pattern Analytics:__
An important step in data analysis is data exploration, to achieve a better
understanding of the data. The Exploratory Pattern Analytics (EPA)
tool works on prepared/preprocessed tabular data. It provides
explanatory patterns, i.e., simple rules between some parameters
(e.g., temperature, pressure) that are predictive for a certain
target parameter (e.g., scrap rate). This provides important insights
enhancing data understanding.
For example, it could be used to better understand why certain known outliers occur
in process data.

\\__%%( color: #003399; font-size: 24px;)This tool supports you to:__
Explore your dataset, by finding interesting groups of data points within your data, which are described through simple patterns.
\\__%%( color: #003399; font-size: 18x;)Example use case:__
For
example, the EPA tool could be used to better understand why certain known
outliers occur in process data. The Exploratory Pattern Analytics
tool makes it possible to find patterns that explain the data, in the
form of rules that associate a certain combination of properties to a
high probability of an outlier occurring. This can be an exploratory
process, using input from business experts to refine the patterns.
Ultimately, the rules found by the Exploratory Pattern Analytics tool
make it possible to identify conditions under which an anomaly is
more likely, making prediction easier and offering possible causal
explanations – so that the anomalous behavior can be managed more
effectively.
