Good day All,   I am having some difficulties getting the new version of the Google Maps Extension to work with a Google API key. I have followed the steps in the supporting documentation but I am clearly missing something.   I have created the API key, downloaded the extension from the marketplace and saved to a directory. When I execute the GetGoogleMapConnectionString I get this result:           And when I run the SetGoogleMapConnectionString I get the following error message: "Unable to Invoke Service SetGoogleMapsConnectionString on PlatformSubsystem : Table [PlatformInformation] does not have a field named [googleMapsConnectionString]".   Any advice to what step I am missing?   Kind regards, Johan Bester

The accuracy of a predictive model can be boosted in two ways: Either by embracing Feature engineering or by applying boosting algorithms straight away. There are multiple boosting algorithms like Gradient Boosting, XGBoost, AdaBoost, Gentle Boost etc. Every algorithm has its own underlying mathematics and a slight variation is observed while applying them. While working with boosting algorithms, we have come across two frequently occurring buzzwords: Bagging and Boosting. Bagging: It is an approach where you take random samples of data, build learning algorithms and take simple means to find bagging probabilities.Boosting: Boosting is similar, however the selection of sample is made more intelligently. We subsequently give more and more weight to hard to classify observations.Below are Default Algorithms used in Predictive Models generated in ThingWorx Analytics:Decision TreeGradient BoostLinear regressionNeural NetRandom ForrestLogistic RegressionGradient boosting is a machine learni

Hi All   Hope somebody can help me. I am tossing up whether to write my own Thing or use the HTTP integration example.    I have read the documentation here and it doesn't really answer many of my questions   http://support.ptc.com/help/thingworx_hc/thingworx_8_hc/en/#page/ThingWorx%2FHelp%2FExtensibility%2FIntegrationConnectors%2FConnectorOview.html%23   How do I add headers? Can headers be dynamic (e.g. thing calls the HTTP connector with different properties) Can Query String be dynamic? How should URL be structured? Which logs contain the HTTP integration errors?   I am looking for an experience similar to postman.   Andrei

Hello Team,   I need to take the data from default persistence provider of thingworx to external data store like hadoop.   I think the solution can be get ModelEntities that has valuestream assigned and get the data entries from particular timestamp from the model,send to hadoop.   Or is there any other solution/alternative to offload data from persistence provider which in our case is postgresql.   Any approach will  be appreciated   Thanks,Regards, Vijay
