Sequence prediction - Help in translate result

Hi, recently i used CPT test file (MainTestCPT.java) with custom dataset that i made and having result like this :

--------------------------------------------------------------------------------
Number of sequences : 383
Number of distinct items: 1049
Largest item id: 1500
Itemsets per sequence: 6.242819843342037
Distinct item per sequence: 6.234986945169712
Occurences for each item: 1.0012562814070352
Size of the dataset in MB: 1532.009564

For the sequence <(1),(383)>, the prediction for the next symbol is: +
---------------------------------------------------------------------------------

I want to ask your opinion on how i should interpret the outcome, since it didn't return any prediction for the next symbol. Thanks in advance

The most likely reason is that you need to adjust the parameters. It is possible that in your training data, there is no sequence that match with the sequence that you want to predict. Thus, no prediction is given. If you adjust the parameters of the prediction model, I think we will get some prediction ;-)

By the way, sorry for the delay to answer. I have been a bit busy during the last few days.
