Thanks for the explanation, Pat! I think the best course of action is for me to read the documentation and understand how the algorithm works. Then, try again with a slightly larger dataset. Thank you very much! On 19 October 2017 at 17:15, Pat Ferrel wrote: > This sample dataset is too small

This sample dataset is too small with too few cooccurrences. U1 will never get i1 due to the blacklist (u1 has already viewed i1 so will not be recommended that again). The blacklist can be disable if you want to recommend viewed items again but beware that they may predominate every recommendat

Pat, this worked! Thank you very much The only odd thing now is that all the results I get now are 0s. For example: Using the dataset: "u1","i1" "u2","i1" "u2","i2" "u3","i2" "u3","i3" "u4","i4" echo "Recommendations for user: u1" echo "" curl -H "Content-Type: application/json" -d ' {
