  1. F# Support in Azure ML

    Azure ML is great. I would like Azure ML to support F# -> with both the code sample gen (currently C#) and the script support (currently R).

    • Time series models

      Would love to see a time series prediction model using a MultiClass Neural Net. Also, where's the N# documentation?

      • C# Support in Azure ML

        Support C# Execution modules. While R and Python are useful in certain situations, C# is useful also. Given the large number of developers who know C# as opposed to R, this opens custom modules to a much wider audience.

        • Azure ML support for DocumentDB

          I wish to implement a project using the new DocumentDB service offered by Azure, which eventually I wish to apply machine learning on the dataset. However, I understand that Azure ML does not currently support ingressing from DocumentDB. Would Azure ML be supporting the ingressing of DocumentDB soon, as this would be the deciding factor on my decision on whether to use DocumentDB or not eventhough the DocumentDB is the ideal datastore implementation for the project. If Microsoft Azure ML be offering the same tight and first class integration for DocumentDB as it does for the other Microsoft datastore options,…

          • Add Package ‘Relaimpo’

            This is a critical package in calculating the relative impact of the components in a multivariate regression model.

            • Enable odbc connection from "Excute python script" module

              Odbc drivers are not installed on machines running the python script. Solving this will enable users to create their own Reader module by using their own business logic to access azure sql.

              • Import data from Azure Data Lake Store

                Right now you can access files on Azure Data Lake Store through a Hive cluster, which is both expensive and hard to set up. Azure ML should have direct access to Azure Data Lake Store files.

                • Support JSON for input/output

                  Several custom algorithms I use are designed expecting input in JSON format. This is ideal for integrating with a web service, but unfortunately ML Azure doesn't seem to support it.

                    JSON parsing is not yet implemented as a separate module. As a workaround for JSON parsing, you could use Execute R Script in following manner:

                    1. Compress the JSON file as zip package and upload to ML Studio as .zip format file.

                    2. Connect the .zip file to Execute R Script rightmost port

                    3. Execute following R script (replace “sample_json.txt” with your file name).

                    library(RJSONIO)
                    library(plyr)
                    data.set = ldply(fromJSON(content=“src/sample_json.txt”))
                    maml.mapOutputPort(“data.set”);

                    Note that this assumes your JSON file holds an array of similar records.

                  • Allow reading line seperated json format from blob storage

                    We're using Stream analytics to write results in a line seperated json format, which is a standard for many other services, but it is impossible to read it from blob storage.
                    the workaround suggested will not help when using prediction experiment and getting the data from blob in a realtime manner

                      • Allow Azure Table Access with SAS Authentication

                        Currently only one storage account can be associated to an ML workspace, leaving SAS authentication as the only option to access other storage accounts. Nevertheless, testing the documented SAS access returns the comment:

                        [ModuleOutput] Azure Table with SAS Uri not implemented yet.

                        Implementing this feature, thus allowing access to multiple storage account, would widely increase the flexibility and applicability of ML to big data solutions.

                          They provide a way a mechanism to directly process data and enable consumption of data in popular BI tools. This should be done for Azure ML as well

                            A lot of the newer Algos require R or Python scripts to execute. LightGMB was built within Microsoft. It would be great if this could be added as a module within Studio ML rather than requiring R or Python.

                            • More flexibility for Support Vector Machines

                              In other machine learning tools, SVM supports different kernel functions, and each function may have additional parameters. I assume "Project to the unit-sphere" is a kernel function, but could not find a definition for that function.

                              A kernel I found useful in many cases was the Radial Basis Function (RBF, parameters C or lambda, gamma), but there are others. It would also be useful to allow defining a custom kernel function, for example with an R script (or whatever language is most appropriate for the SVM implementation used)

                              • Support more recent versions of R

                                AzureML currently support only old versions of R:
                                * CRAN R 3.1.0, released in 2014
                                * Microsoft R Open 3.2.2, released in 2016

                                Some R packages are not available in these older versions, or in some cases the package is available but it is an older version of the package with incompatible differences with the newer version.

                                Several newer versions of both CRAN R and Microsoft R are available. AzureML should support them. Also, going forward, there shouldn't be such a considerable delay between R major version releases and their availability in AzureML

                                • Multiple inputs for Evaluate Model (only 2 currently possible)

                                  Would be easier to work with & compare multiple models. having to cross-pairing all models is too slow to design & hard to evaluate.

                                  Even if the output when multiple models would have fewer features than the default 2 input evaluate. (ex: fewer visualization options, metrics) But at least a good subset of main evaluation metrics should be visible.

                                  • Ensemble Models in Azure ML Studio

                                    It would be great if in an Azure ML Experiment I could ensemble (with personalized weights) different Models; such as, Neural Networks with Desicion trees.

                                    So far, I've only make this manually using a Python script to average the outputs of the models I want to ensemble. But since the python script module only takes 2 dataframas as inputs it takes a lot of scripts to make a big ensemble between 4 or 5 models

                                    • More Help on Error 0000: Internal Error's

                                      I get lots of these. A little bit more help finding out how to rectify them would be useful. Mainly on the training steps. I suspect its too many columns, but can't tell. Can more information be surfaced in the error logs?

                                        • Configurable timeout for experiments and web services

                                          Some bugs/errors could cause experiments or web service to run longer than expected. This can lead to high costs if several executions never ends.
                                          There should be configurable timeouts, so that any run that exceeds this timeout is terminated:

                                          - Workspace global timeout: applies to all experiments and web services in a workspace
                                          - Experiment and web-service specific timeouts
