@ -3000,7 +3000,7 @@ Weights are assigned using two criteria.
The first criterion is the size of the pattern (i.e., the number of nodes in the pattern), since a pattern with twenty nodes is a lot more specific than a pattern with only one node.
The second criterion is the amount of times a pattern occurs across all messages.
If all messages contain a specific pattern, it can not be reliably used to determine which message should be predicted and will therefore be assigned a smaller weight.
The weights are calculated using the following formula below.
The weights are calculated using the formula below.
\[\operatorname{weight}(pattern) = \frac{\operatorname{len}(pattern)}{\operatorname{\#occurences}(pattern)}\]
