cleverminer 1.2.5

Beyond apriori. CleverMiner is the package for enhanced association rule mining (eARM). Comparing to standard association rules, it is very enhanced, because the package implements the GUHA procedures that generalizes apriori and association rules in many ways. Rules are based on categorical data that can be easily visualized and interpreted. Their if-then with probability allows easy deployment by human realized processes. Interpretable & explainable knowledge mining.

CleverMiner

The CleverMiner is an enhanced association rule mining library

Beyond apriori. CleverMiner is the package for enhanced association rule mining (eARM), that are INTERPRETABLE, so by definition one of few intrinsic methods of explainable AI (XAI). Comparing to standard association rules, it is very enhanced, because the package implements the GUHA procedures that generalizes apriori and association rules in many ways. Rules are based on categorical data that can be easily visualized and interpreted. Their if-then with probability allows easy deployment by human realized processes. Interpretable & explainable knowledge mining.

The CleverMiner in more detail

In general, apriori is looking for rules {ItemSet} -> {Item} (Base, prob). GUHA goes further and instead of items (boolean attributes), list of categorial attributes and combination of values (nominal and several strategies for ordinal -- joining categories) is searched on left and right hand side. Moreover, GUHA has much more possibilites and several other procedures, like mining interesting histograms, finding couples of rules etc.

To run cleverminer procedures, use dataframe with categorical variables only. Cleverminer prepares all variables and values for future reuse.

Optimized in many ways

CleverMiner has optimized space search in several ways.

• first, it encodes dataframe into internal format that is optimized for frequent querying for similar pattern, then it queries the dataframe many (typically several thousand or tens/hunderds thousand) times.
• the algorithm has also optimizations by the derived properties of individual procedures (e.g. when procedure A finds that expanding rule will in every case lead into rules that does not meet requirements, it skips entire branch). This optimization typically reduces the mining time significantly.
