Semantic pattern extraction from continuous itemsets

A semantic pattern extraction system comprising:

• one or more processors;
• one or more computer-readable storage media storing instructions thereon for causing the one or more processors to perform a method comprising:
• performing an entropy-based discretization on a continuous itemset to generate a discretized itemset, individual of the items in the continuous itemset comprising a physical design feature value for one or more physical design features and an event value indicating the presence or absence of one or more manufacturing defects;
• identifying a set of candidate semantic patterns from the discretized itemset by performing frequent set mining on the discretized itemset;
• reducing the set of candidate semantic patterns to one or more final semantic patterns;
• determining a score for individual of the final semantic patterns;
• and
• displaying the final semantic patterns on a display in a ranked order, the ranked order based at least in part on the score for the individual final semantic patterns.

A semantic pattern extraction system comprising:

• a discretization means for performing entropy-based discretization on a continuous itemset to generate a discretized itemset, individual of the items in the continuous itemset comprising a physical design feature value for one or more physical design features and an event value indicating the presence or absence of one or more manufacturing defects;
• a mining means for identifying a set of candidate semantic patterns from the discretized itemset by performing frequent set mining on the discretized itemset;
• a reduction means for reducing the set of candidate semantic patterns to one or more final semantic patterns;
• a scoring means for determining a score for individual of the final semantic patterns;
• and
• a display means to display the final semantic patterns in a ranked order, the ranked order based at least in part on the score for the individual final semantic patterns.
