Dear all, 
I am using scala ecommerce recommendation template and now I would like to have 
an option to recommend items based on specific price range. Would it be 
possible using the template or I may have to modify the template?

Universal Recommender date boosts

[Tom McCaul]

Hi,

I'm setting up UR to return an ordered list of items for a category by
popularity but I wanted to boost new in items.

So far, I'm using an attribute to create a boost for those new products but
this isn't the most ideal set up.  I'd prefer for the boost to be weighted
over time, so on day 1, the product receives the biggest boost and by day
28 (just before it's no longer considered new) it's at its lowest.

Does anyone have any suggestions how I could best approach this?

Thanks,
Tom

pio train -- --master yarn-cluster | Error

[amal kumar]

Hi,

We are using Spark on yarn and after referring the below URL, we have been
able to submit the jobs to yarn from remote machine (i.e. PredictionIO
Server).

http://theckang.com/2015/remote-spark-jobs-on-yarn/

1. copied core-site.xml and yarn-site.xml from Yarn cluster onto remote
machine (i.e. PredictionIO Server)
2. set the HADOOP_CONF_DIR environment variable in spark-env.sh (locally
installed copy) on the remote machine to locate the files core-site.xml and
yarn-site.xml


Now, when I am trying to train the model using the below command, I get a
new error.

pio train -- --master yarn-cluster

*Console Error Logs:*
java.io.FileNotFoundException: File does not exist:

*Yarn Error Logs:*

I also tried to pass the file path, but no luck.

Re: ecommerce template prediction based on price

You could add the price as "properties" of item.
Then modify the Query class to add 'price' as one of field

Modify isCandidate() function to take the price into account
