Remove subsets from FP Growth output

Hi, Is there a good way to remove all the subsets of patterns from the output given by FP Growth? For example if both the patterns pass the confidence and support thresholds: [Attribute1 = A, Attribute2 = B] -> [Output=C] [Attribute1 = A] -> [Output=C] I want to choose only [Attribute1 = A] ->

Hi Shivin, I'm interested in collaborating with you on this project. I have been using pyspark for a while now and quite familiar with it. Do you have any plan on how to proceed? Thanks, Aditya On Sat, 27 Jun, 2020, 2:58 pm Shivin Srivastava, wrote: > Hi All, > > I have

Re: Spark FP-growth

ought because of FP growth's depth first nature it might not be possible. My experience with Fp-growth has largely been in python where the API is limited. I will take a look at the scala source code and get back to you with more concrete answers. Thanks & Regards, Aditya On Thu, 7 May,

Hi, I understand that this is not a priority with everything going on, but if you think generating rules for only a single consequent adds value, I would like to contribute. Thanks & Regards, Aditya On Sat, May 2, 2020 at 9:34 PM Aditya Addepalli wrote: > Hi Sean, > > I un

n the data. Sometimes this can be 1e-4 or 1e-5, so my minSupport has to be less than that to capture the rules for that consequent. Thanks for your reply. Let me know what you think. Regards. Aditya Addepalli On Sat, 2 May, 2020, 9:13 pm Sean Owen, wrote: > You could just filter the i

I am not sure that is feasible. I am willing to work on these suggestions, if someone thinks they are feasible. Thanks to the dev team for all the hard work! Regards, Aditya Addepalli

Spark Executor Lost issue

I have a spark job which runs fine for small data. But when data increases it gives executor lost error.My executor and driver memory are set at its highest point. I have also tried increasing--conf spark.yarn.executor.memoryOverhead=600but still not able to fix the problem. Is there any other

For testing purpose can you run with fix number of executors and try. May be 12 executors for testing and let know the status. Get Outlook for Android On Fri, Sep 23, 2016 at 3:13 PM +0530, "Yash Sharma" wrote: Thanks Aditya, appreciate the help. I had the exact tho

Hi Abhishek, From your spark-submit it seems your passing the file as a parameter to the driver program. So now it depends what exactly you are doing with that parameter. Using --files option it will be available to all the worker nodes but if in your code if you are referencing using the spe

Re: Spark job fails as soon as it starts. Driver requested a total number of 168510 executor

Hi Yash, What is your total cluster memory and number of cores? Problem might be with the number of executors you are allocating. The logs shows it as 168510 which is on very high side. Try reducing your executors. On Friday 23 September 2016 12:34 PM, Yash Sharma wrote: Hi All, I have a spa
