Read DetailsFirst, your colleagues come back to you explaining that they run the Apriori algorithm setting the support threshold at 0.5 and the confidence threshold at 0.7. The output showed that 0 rules were generated. Therefore, they conclude there is no meaningful recommendation that can be made for viewers of the TV show Friends. You feel their interpretation is not correct and you think of ways to run the algorithm again. Identify which of the following actions you could take to improve the results obtained by your colleagues.
