QUESTION
I am having a number of rules which are inserted in the drools session and I've got them printed using event listener provided by KieSession. Here is the code:
...ANSWER
Answered 2020-Sep-08 at 13:54In your DRL file(s) you have access to a variable called drools. This is an instance of the KnowledgeHelper class, which gives you access to a bunch of information about the rules, environment, working memory, etc. The link is to the source code for KnowledgeHelper, since the documentation only discusses the most commonly used methods (usually for getting stuff like the rule name.)
From the drools variable, you can access the WorkingMemory object (link to source), which gives you access to all the objects in working memory. You should be able to use iterateObjects or iterateFactHandles to walk the data in working memory as needed.
Obviously I'm not familiar with your specific use case, so you'll need to update any code to match your use case. But let's say I want to get all AttackCategory instances remaining in WorkingMemory, I might do something like this:
QUESTION
I needed to write a program that would figure out the probability that if I roll a dice 12 times every number on the dice will appear at least once. The question was proposed that there are 6 people and we all decided to roll a die once a month for a year. Whoever has their number come up gets to pick the restaurant. What is the probability that everyone will get to pick their restaurant at least once. So I wrote a program that will roll a dice 12 times and keep track of the outcome. If every number in my random method comes out, that means that everyone got a chance to pick a restaurant (Success). If one of the numbers stays at zero in a 12 roll set, that means not everyone got to pick a restaurant (Failure). My program works great and runs when the user types "roll" and quits if the user types "Q". It keeps track of successes and divides that by number of times the program is run. I started out with a very simple die roll program that runs from a while loop, and then built all of the functionality from there. In the end, I realized that I need my program to run so 100 or 1000 times to find a good probability average. I'm not best coder as I guess you can see from my code, but I coded myself into a corner, and want to be able to run this "n" times without me spending hours trying to figure this out. I'm sure better coders on here would be able to help me very easily. Thank you in advance. Here is my code.
...ANSWER
Answered 2020-Apr-02 at 03:44There's a few things here. First, to your specific question, you could just modify your loop so that instead of checking for input in main(), you just loop a fixed number of times. You might do that with something like:

QUESTION
I'm trying to build a naive bayes based classifier for 1000 positive+negative labled IMDB reviews (txt_sentoken) and weka API for Java.
As I wasn't aware of StringToWordVector, which basically provides a BagOfWords model that reaches an 80% accuracy, so I did the vocabulary building and vector creation myself, with an accuracy of only 75% :(
Now I'm wondering why my solution is performing so much worse.
1) From my 2000 reviews, I build the BagOfWords:
...ANSWER
Answered 2017-Dec-28 at 07:18Reading through Weka's StringToWordVector documentation, there seem to be a couple of implementation details different than yours. Here are the top two, based on how likely they are to be the reason for the performance difference you see, in my opinion:
- It seems that by default, the resulting vector is boolean (i.e. noting the existence of a word, rather than number of occurrences)
- If the class attribute is set before vectorizing the text, a separate dictionary is built for each class, then all dictionaries are merged.
While any of them (or other, more minor differences) could be the culprit, my bet is on the second point.
The built-in class allows setting and unsetting each of these options; you could try re-running the 80% version using StringToWordVector with the -C option to use number of occurences rather then a boolean value, and with -O, to use a single dictionary across both classes.
This should allow you to verify whether any of these is indeed the culprit.
EDIT: Regarding the first point, i.e. counting occurences vs. noting word existence (also called Bernoulli and multinomial models), there were several academic papers at the 90s which looked into the differences, e.g. here and here. While usually the multinomial model works better, there are also opposite cases, depending on corpus and classification problem.

today I am here to request any helping to sort out the 5~ unique errors I have left to compile this Snakes & Ladder Game. I am providing the errors I am getting below and also the code.
I am providing all the information I feel is necessary to provide me some pointers. Thank you in advance. Any help is much appreciated.

QUESTION
I recently completed a snakes and ladder game required for my school but my peer can perfectly compile this code while I get same error over and over again. I have tried many different approaches but I am not quite sure what else to do.
I tried downloading prior versions of Haskell and that did not help. I also installed lens package using "cabal install lens" and imported the Control.Lens package using ghci -> import Control.Lens before compiling the program.
When I try compiling the code, I get the following error. File name is Main.hs
...ANSWER
Answered 2017-Apr-04 at 22:45moduleline must be above imports- Don't need to indent everything after the
whereon the module line - Put a blank line between every function/data decl/instance for readability
- Provide a type signature on every function
- Do not wait to compile until you are done writing, you should compile and test incrementally so you can fix design flaws with minimal effort
- Compile with the
-Wallflag to give you reasonable suggestions on changes that would improve readability
Once you clean it up into a workable state, you can see what type errors you get and work on fixing those.
