If Pills are to be taken “After” Food, we can notice violation of this activity! Anomaly Detection If Cooker is Spoiled should we call emergency or normal repair? Maintenance If Oven used for Turkey, Is turkey at Home? Temporary Need Analysis Increase prediction accuracy with association rules! Improve Prediction

 Step 1: Eliminate Unnecessary datasets and identify the most frequent Itemset using Apriori Algorithm.  Step 2: Use Weight based Relation analysis to identify best relation to remove ambiguity.
