Version 11.1.0 - October 21st, 2022

DSS 11.1.0 is a very significant new release with both new features, performance enhancements and bugfixes.

Compatibility note

The version of one of the libraries used by Visual Time Series Forecasting, gluonts, has been upgraded. Time Series Forecasting models may need to be retrained.

Major new features and enhancements

New chart types

  • Added a Treemap chart, ideal for representing data where dimensions form a hierarchy

  • Added a KPI chart, to display individual aggregated features as single numbers (such as global sum of sales)

Python export of models

It is now possible to directly export DSS models to Python code, for usage in any Python code outside of DSS. This comes in addition to the pre-existing Java export, for usage in any Java code outside of DSS, and PMML for usage in any PMML-compatible scoring system.

For more details, please see Exporting models

MLflow export of models

It is now possible to directly export DSS models to MLflow, for usage in any MLflow-compatible scoring engine that is compatible with the “python_function” flavor of MLflow.

For more details, please see Exporting models

Enhancement of Excel exports

  • Exporting to Excel now properly respects string fields with leading zeros, and does not remove leading zeros anymore (more generally speaking, Exporting to Excel now properly respects storage types)

  • Exporting to Excel now also shows dates as valid dates in Excel

Deployment of clustering models to API node

It is now possible to deploy clustering models to the API node, for direct attribution of clusters to previously-unseen records.

Model explainability for MLflow models

Imported MLflow models can now benefit from a large panel of model explainability capabilities, just like DSS-trained models.

Support for R 4

DSS can now use R 4. In order to use R 4, you need to run the R integration procedure with “R” in the PATH pointing to R 4. All code environments then need to be rebuilt.

Cloud Stacks setups are still on R 3.6, and will switch to R 4 in DSS 12.

Performance & Scalability

  • Much faster (up to thousands of times faster) computation of dependencies for extremely complex flow graphs (notably flows with multiple successive “branch-out / branch-in” patterns)

  • Global performance enhancement for all visual recipes running on DSS engine (up to 50% faster for sync and prepare recipes)

Version 11.0.0 - July 12th, 2022

DSS 11.0.0 is a major upgrade to DSS with major new features.

Major new features

Visual Time Series Forecasting

Time Series Forecasting is now natively available in DSS Visual ML. Visual Time Series Forecasting features many capabilities:

  • Single or multiple series

  • Multiple horizon forecasting

  • Multiple algorithms, including deep learning algorithms

Time Series Forecasting are fully deployable and governable like other DSS Visual Models.

For more details, please see Time Series Forecasting

Code Studios, including Visual Studio Code, JupyterLab and RStudio

Code Studios allow DSS users to harness the power and versatility of many Web-based IDEs and web application building frameworks.

Code Studios allow you, for example, to:

  • Edit and debug Python, R, SQL, … recipes and libraries in Visual Studio Code

  • Edit and debug Python or R recipes, notebooks, libraries, … in JupyterLab

  • Edit and debug R recipes and libraries in RStudio Server

For more details, please see Code Studios

Image Labeling

In order to create and fine-tune image models (classification and object detection), you first need labeled images. Labeling is often a tedious task.

DSS now features a native Image Labeling capability, with the following features:

  • Support for image classification and object detection use cases

  • Ability to invite annotators (people who label the images)

  • Efficient interface for annotators with keyboard shortcuts

  • Ability to request annotations from multiple annotatorss

  • Annotations review process with management of conflicts between annotators

This new capability allows you to perform even more of the entire Machine Learning cycle for computer vision in DSS.

MLOps: Experiment Tracking

DSS now includes an experiment tracker for logging parameters, performance metrics, models, and other metadata when running your machine learning code, and for visualizing results of such experiments.

The DSS Experiment Tracker leverages the well-known MLflow Tracking API, which allows you to seamlessly port existing or 3rd party experiment tracking code and get all DSS benefits.

For more details, please see Experiment Tracking

MLOps: Feature Store

A Feature Store helps Data Scientists, build, find and use relevant data for models in order to build efficient models faster.

Most key components of a Feature Store are native capabilities of DSS:

DSS 11 adds a new Feature Store section, which acts as the central registry of all Feature Groups, a Feature Group being a curated and promoted Dataset containing valuable Features.

For more details, please see Feature Store

Data Visualization: New Pivot Table

The Pivot Table has been strongly overhauled. It now supports:

  • Multiple dimensions on rows and columns, with subtotal support

  • Excel Export of multiple dimensions and multiple measures

For more details, please see Charts

Quick Sharing

Project administrators can now enable “Quick Sharing”, which allows any user who has read access to the project to share a dataset to his own project, without having to ask the project administrator first.

Quick Sharing can be globally disabled by instance administrators.

For more details, please see Shared objects

Access & Sharing requests

Project administrators can now choose to make their project “discoverable”, which allows users who don’t have access to the project to still discover its existence and basic information about it (name, description, …), and then to request access to it.

Project administrators receive notifications about access requests, and can manage them, grant them or reject them.

Similarly, users who have access to a project can now request that datasets be shared with their own projects, and project administrators can manage these sharing requests (if they don’t have Quick Sharing enabled).

These mechanisms can be globally disabled by instance administrators.

For more details, please see Requests

Create if, then, else processor

This new visual data preparation processor performs actions or calculations based on conditional statements defined using an “if, then else” syntax.

It can be used notably to create new columns based on conditions on the values of other columns. While this was previously feasible using formulas or the Switch case processor, the new Create if, then, else statements processor can provide much more flexibility, without having to write complex formulas.

For more details, please see Create if, then, else statements

Flow Document Generator

In regulated industries, it is often required to document flows, at creation and after every change for traceability. This is often tedious. DSS now features the ability to automatically generate a DOCX document from a Flow, which documents the whole flow, including datasets and recipes details.

For more details, please see Flow Document Generator.

Govern: Projects and bundles governance

The Govern Node now supports managing, governing, and controlling deployment of Project Bundles in the Deployer

Dataiku Cloud Stacks on GCP

Dataiku Cloud Stacks is now available on GCP.

For more details, please see Dataiku Cloud Stacks for GCP

Other notable enhancements and features

Outcome Optimization for regression

The “What-If” feature now supports Outcome Optimization for regression problems. Outcome Optimization allows you to start from a given record, and to explore the neighborhood of this record to find the changes to input features that would lead to changes in the predicted value, towards either the largest, smallest, or a specific value. You can select which features can be modified and which can’t.

Nested filters

In locations where visual filters can be used, it is now possible to nest complex boolean conditions, such as:

  • If col1 is 2

  • AND

    • col2 is 3

    • OR col3 is 4

This applies to:

  • The Filter visual recipe

  • The “Create-if-then-else” prepare processor

  • The “Pre/Post filters” of all visual recipes

  • Filters in Explore and Charts sampling

  • Filters in Visual ML

OIDC authentication

In addition to SAMLv2, OIDC can now be used as SSO protocol for logging in to DSS

For more details, please see Single Sign-On

SSO support for Fleet Manager

It is now possible to log in through SSO on Fleet Manager

For more details, please see Installing and setting up

“List folder content” recipe

This new visual recipe takes a managed folder as input, a dataset as output, and writes in the dataset the listing of files in the managed folder.

This recipe is especially useful for image labeling and computer vision use cases.

For more details, please see List Folder Contents

Workspace discussions

Discussions are now available on workspaces

Data Visualization: Count Distinct and Count Not Null aggregations

All aggregated charts (columns, bars, pies, lines, areas, pivot table, …) now support the “Count Distinct” and “Count Not Null” aggregation functions for measures.

This also now makes it possible to have non-numerical measures

For more details, please see Charts

Data Visualization: multiple layers on Geo Map

It is now possible to draw multiple layers with different geometries on the Geo Map chart

For more details, please see Geographic data

Data Visualization: additional customization options

The following can now be customized:

  • Ability to change the name of a measure in the legend and tooltip

  • Ability to change the name of a dimension in the legend and tooltip

  • Ability to reformat numbers on axis and in cells of the pivot table

For more details, please see Charts
