Web-based GUI application for data analysis

jstat-gui's Issues

Update guide for MongoDB integration

Add ClassificationComputeController

Create load data set use case card

handled inn PR: #7

parsing data set columns

it seems we don't parse data set columns as numeric samples.

testing shows that we are currently having NaN therefore empty values

Load data from MongoDB

Add Analysis url

handled in PR: #10

When Quit is confirmed we should display restart and not Quit

Quit shuts down all the workers running in the background. Furthermore, it disqualifies any initializations performed. This is because we want to allow the app to end gracefully. After completing effectively JStat cannot function so we need to show the Restart button instead of Quit

loading two data sets

when loading two data sets we must provide the user with the choices to decide which data set to use and which columns (multiple-choice would be nice).

for the time being we can only use a single data set and select one or all the columns

Spring boot dependencies

decide on dependency injections

Add ClusteringComputeController

Add Quit url

handled in PR: #7

Drop dataset URL

Create dashboard for background running jobs. User should be able to cancel or restart jobs via the dashboard

Add Configuration file

The configuration file should specify:

• Where datasets are located
• How many threads to use
• Database connections
• Compute engines to use

Add LinearRegressionComputeController

The LinearRegressionComputeController is responsible for fitting a linear model with a given data set

• GET:

1. Should allow the user to select the data set to be used for the fitting

2. From the specified data set the user should be able to:
   1. Select which columns will form the features of the model (at least on column is needed)
   2. Select the polynomial order of the feature (default should be 1)
   3. Select which column will be used for the labels. If the column selected is in the column set from 1 above an error should be generated

            4. Select the error function
                 1. Mean squared error
                  2. Sum squared error
           5.  Select regularization method
                  1. Lasso
                  2. Ridge
                  3. ElasticNet
            6. Select the optimization method
                  1. Gradient Descent
                  2. Newton solver
   

• POST: Accepts the filled user form and creates the task(s) for the computation

It redirects to a page where the computation completion can be queried. Thus we should be able to distinguish between computing tasks. e.g. use some sort of name mangling

Consider: We could write to a DB when a calculation is started and finished a poller can then query this and once the computation is finished serve the results somehow

The result is should be a set of coefficients describing the model.

Consider: The user should be able to save in the DB the computed model for future use under a name

Add load dataset functionality

handled inn PR: #7

Create plot bar-chart use case card

Load data from ElasticSearch backend

handled in PR: #39

Merge datasets URL

create index page

create a spring boot application which opens an index page.

Add DescriptiveStatisticComputeController

The DescriptiveStatisticsComputeController is responsible for two things:

• GET: Serves the page to the client that allows to set a descriptive statistics computation
  The user should:

1. Specify the data set for which the computation is requested
2. Specify the column or "All" for which the computation is to launched
3. The columns of the data set should come from the backend

• POST: Accepts the filled user form and creates the task(s) for the computation

It redirects to a page where the computation completion can be queried. Thus we should be able to distinguish between computing tasks. e.g. use some sort of name mangling

Consider: We could write to a DB when a calculation is started and finished a poller can then query this and once the computation is finished serve the results somehow

Consider: The user should be able to save in the DB the computed model for future use under a name

Redesign beautify index page

integrate jstat dependency into jstat-gui

handled in PR: #41

Describe dataset URL

detail.wrappers should be moved to gui.wrappers

handled in PR: #36

mongoDB clear()

the user should be able to the collections from the locally created mongodb instance

Add MongoDB as backend

handled in PR: #30

Docker integration

do some analysis button should move to the navigation so that we can easily access the analysis methods in one click

Add configuration file reader

Reads the supplied configuration file and validates it

deploy jstat-gui

research on how and where to deploy the app. netlify - heroku

fix logic in EDAController.edaAnalysisView

The following code causes an exception to be raised

 // in order to do an analysis we need the list of the loaded data sets
        List<String> dataSetNames = JStatGuiGlobalData.dataSetContainer.dataSetNames();

        if (dataSetNames.size() == 0) {
            dataSetNames.add("No data sets loaded");
        }

        List<DataSetViewInfoHolder> dataSets = new ArrayList<>();

        for (int i = 0; i < dataSetNames.size(); ++i) {

When dataSetNames.size()==0 we should simply return a message that nod datasets have been loaded
