  1. to enable Spark ML support instead of Mllib

    I need to use ML features such VectorAssembler. Right now I can't train a model if some of my data are strings and others double

    • Demand forecasting (Retail)

      A demand forecasting template based on prices and sales history would be really nice for retailers. Once the model is trained, they could adapt their prices and discounts in order to maximise their profit.

      • Support Storing Events in Cassandra

        Cassandra has been gaining momentum versus hbase as it is easier to set up and scales better, especially for read-intensive workloads [1].

          • problem with the vagrant provider

            hi,

            The box you're attempting to add doesn't support the provider

            provider. Double-check your requested provider to verify you didn't

            If you're adding a box from HashiCorp's Atlas, make sure the box is

            • Hbase and Spark not starting in PredictionIO

              Hi All,

              Can you please guide me how to solve this issue.
              Actually i have installed predictionIo on top of cloudera distribution (5.3.2).
              Ecosystem Versions in CDH are as follows:

              1) Hbase (0.98.6-cdh5.3.2)2) spark (1.2.0-cdh5.3.2)3) elastic search (1.5.0)4) java jdk (1.7.0_67)5) predictionIo (0.9.1)6)

              Hadoop (2.6.0 )

              I have successfully installed the Elasticsearch and PredictionIO on CDH Cluster by following the below link:
              http://docs.prediction.io/install/install-linux/

              Now every thing is ready when i try to start the predictionIo i am getting the following error
              Command to start the predictionIo is (./pio-start-all) and i am attaching the screenshot of the error which i am…

              • Evaluation / Cross-validation

                I don't understand how anyone could be any of this without performing some sort of validation on their models?!? Without performance there is no way to gauge how well the model is performing, ...it could be giving horrible results and you would never know!

                The https://github.com/PredictionIO/template-scala-parallel-classification template has Evaluation implemented but I think it should be a top priority to get the rest of the templates implemented with some sort of validation! At the very least there should be some sort of MSE cross-validation implemented for the Recommendation template used in the quickstart example.

                • Integrate Business Rules Workbench tool

                  While predictive algorithms and engines provide the horsepower what is missing in the stack is for business users to specify simpler rules to produce desired output data from input raw data. Such a feature with an UI workbench for business users will help add the 80% of the business needs without programming involved.

                  • Allow other developers to create templates for prediction.io

                    It would be great if i could create a template of my customized engine.

                    Other developers could use my template to create their engines. So they do not need to do the same work again.

                    I possible solution would be to create engines based on a template file.

                              • Get match value for specific items provided to the engine

                                Can we get an API for the ItemRec engine where we provide the userid and a list of itemids, and get their match values as a result?

                                This can be useful for recommending location based items to the user.

                                For example, a user is out looking for restaurants, we can collect a list of restaurants around that location and pass them to the ItemRec engine upon which it can return the match value for the user.

                                This list can then be presented in descending order.

                                • Add behavior(u2i) REST + API library calls

                                  I'm not sure if this feature exists already, but... We need to demonstrate WHY certain recommendations were made. For this we need to retrieve the underlying "u2iActions" for a specific user. It would also be nice if this response can be enriched with all additional user and item data.

                                  I am on PIO 0.7.3... so it might already be in 0.8.0 without me even knowing... for now we are querying MongoDB directly.

                                  Many thanks, keep up the good work!!
