This may simply just not be available yet, didn't see it in any of the doc surrounding training a model.  

You can specify what percentage of the dataset gets used for training with the remainder being used for testing.  Is there any mechanism to explicitly define a dataset to use for training and another dataset to be used for testing?  

It would seem like this would be valuable for tuning the model, having a static test data set to always test against while being able to modify the training dataset to increase the accuracy.
Is it possible to update trained dataset in einstein API?

Hello,

I'm trying to set up a Lightning app that will allow a user to provide a url to a zip file, have that zip file loaded as a dataset into the predictive vision service, then specify the newly created dataset to be trained into a datamodel. I'm able to load the data model from the menu, and get back a dataset id.

But I'm stuck on how to call the training service. I modified the provided VisionController code as follows:

    @AuraEnabled
    public static String postDatasetTrain(string datasetId, string datasetName) {
        // Get a new token
        JWT jwt = new JWT('RS256');
        jwt.cert = 'SelfSignedCert_18Jul2016_235259';
        jwt.iss = 'developer.force.com';
        jwt.sub = 'joseph.daily@careerbuilder.com';
        jwt.aud = 'https://api.metamind.io/v1/oauth2/token';
        jwt.exp = '3600';
        String access_token = JWTBearerFlow.getAccessToken('https://api.metamind.io/v1/oauth2/token', jwt);      
        
        String VISION_API = 'https://api.metamind.io/v1/vision';
        String DATA_TRAIN = VISION_API + '/train';
        string contentType = HttpFormBuilder.GetContentType();
        //  Compose the form
        string form64 = '';      
        form64 += HttpFormBuilder.WriteBoundary();
        form64 += HttpFormBuilder.WriteBodyParameter('name', datasetName);
        form64 += HttpFormBuilder.WriteBoundary();
        form64 += HttpFormBuilder.WriteBodyParameter('datasetId', datasetId);        
        form64 += HttpFormBuilder.WriteBoundary(HttpFormBuilder.EndingType.CrLf);
        
        blob formBlob = EncodingUtil.base64Decode(form64);
        string contentLength = string.valueOf(formBlob.size());
        //  Compose the http request
        HttpRequest httpRequest = new HttpRequest();
        
        httpRequest.setBodyAsBlob(formBlob);
        httpRequest.setHeader('Connection', 'keep-alive');
        httpRequest.setHeader('Content-Length', contentLength);
        httpRequest.setHeader('Content-Type', contentType);
        httpRequest.setMethod('POST');
        httpRequest.setTimeout(120000);
        httpRequest.setHeader('Authorization','Bearer ' + access_token);
        httpRequest.setEndpoint(DATA_TRAIN);
        
        Http http = new Http();
        HTTPResponse res = http.send(httpRequest);
        system.debug('res: ' + res);
        system.debug('res.getBody(): ' + res.getBody());
        return res.getBody();
    }    

 

But the response that comes back is always a 403 : forbidden message.

Is there anything obvious causing this in my code?

Hi I have tried to register using the http://www.developerforce.com/events/streaming_api_upgrade/registrations link but every time it takes me to different page.

 

Please can any one guide me how to get registered to use/enable the Streaming API.
