Temporal sequence analysis

I have a set of alarm codes which are occuring over many days that finally lead to a failure. Is there any algorithm which can take in the complete sequence of alarm codes along with the timestamp to generate a pattern leading to failure?See More

"Simple support Low and Confidence high !! After this step prune rules with rhs refers to fault."

"Thanks, I am using alteryx for it and using association rules i am trying to find out the rules for the problem statement. I have kept my support as low as possible but if i am keeping my support and confidence extremely low say 1 percent each,…"

" A general approch would be use the alarm data as sequential data and use sequential data mining algos to find rules. Fault related alarms would be very less in percentage terms in the database of alarms so you may have to reduce support value…"

I am trying to find a group of set of alarms which lead to a failure and following apriori algorithm for it. I have a small dataset which comprises of 70 failure units and 750 healthy units. I am trying to take a standard 2 percent of support and 0.75 of confidence as a starter to get LHS - > { failure}however no relations appear.How do we need to set our support, confidence and lift when we don't get the desired relation?See More
