Let’s first walk through a core data science scenario in Fabric, in the context of a typical data science process, to illustrate how data science in Fabric accelerates predictive business insights:

Problem formulation and ideation

The process starts with formulating a question, Collaboration across multiple roles is required for answering these questions. This step is aided by easy access to the same source of truth, such as business metrics, logic, and data analysis tools. Semantic link is a new feature we are launching that will drastically simplify handoffs and ease collaboration between data scientists and stakeholders.

Data discovery and pre-processing

Data engineering teams will build Lakehouses that data scientists can consume. Data scientists will need to further pre-process data to solve problems with ML tools. We are adding a new tool called Data Wrangler to help boost productivity during this tedious step.

Experiment and build ML models

For building ML models, we allow users to create and track ML experiments and models using MLFlow. Users can leverage library management and build environments using third party libraries for developing ML solutions, and the rich SynapseML Spark library that we own and maintain enables model training and ML feature construction to be done at large scale.

Enrich and operationalize

Finally, to enrich and operationalize data with predictive models, data science users can schedule their batch prediction scripts and leverage our scalable PREDICT function to speed up the process. Multiple options exist for operationalization of batch scoring. For example users can leverage a lightweight scheduling of Notebooks to run on a regular basis or schedule Spark jobs that run as part of data pipeline steps.

Gain insights

With the PBI Direct Lake mode, access to predicted values in Lakehouse tables is seamless without the need to load data. Your BI reports will have automatic access to the latest enriched data to help accelerate your predictive business insights!

Through a combination of various well integrated experiences available to a wide range of analytics roles, Microsoft Fabric enables users to successfully complete their data science projects end-to-end.


What’s included in Synapse Data Science?

Now that you hopefully have a better understanding of how Microsoft Fabric helps to better integrate data science with analytics and BI, let’s take a closer look at some of the new features and experiences we are introducing.

Data prep and code generation with Data Wrangler

Data Wrangler, a powerful, intuitive tool for data wrangling and preparation. Data Wrangler makes data cleansing and preparation easier than ever before, while still allowing users to take advantage of the power of coding and reproducibility of Python. The dynamic data display, built-in statistics and chart-rendering capabilities along with the ability to get started with Pandas data in just a few clicks, make this tool easily accessible to a range of experience levels, from novice developers to seasoned professionals. Future updates will include support for Spark and a natural language processing “to code” functionality via Azure OpenAI.


ML models and experiments as first-class citizens with MLFlow

We are also making machine learning models and experiments first-class citizens in Fabric. Built-in support for ML models and experiments allows users to manage models and track experiment runs using standard MLFLow APIs. Comparison experiences make it easy to compare different experiment runs and auto logging helps capture key metrics automatically as users author code to train models. The Microsoft Fabric MLFlow tracking store is powered by Azure Machine Learning, which opens the possibility of valuable integrated experiences in the future.


SynapseML, a comprehensive machine learning library for Spark

Additionally, we bring you the Synapse ML Library, the richest machine learning library for Spark, owned and maintained by Microsoft. With the goal to simplify distributed and scalable machine learning, this library provides access to many different ML tools and easy to use APIs for applying ML and enriching data at scale. Core capabilities include distributed ML with performant and popular algorithms like LightGBM as well as full MlFlow support for SynapseML models. Spark operators help users to work with pre-trained AI models from Azure Cognitive Services, including the new Azure Open AI features, for applying foundation model powered transformations directly on data with Spark.

Enrich data in your Lakehouse with scalable PREDICT

We facilitate the operationalization of ML models with the scalable PREDICT function for distributed batch scoring on Spark, allowing users to process predictions without moving any data. Users can write the enriched data to the Lakehouse and serve it seamlessly to BI reports with the powerful Power BI Direct Lake capability. Additionally, we introduce an easy-to-use guided experience that helps users quickly and easily generate code to apply their ML models.


R Language support

We understand that many users depend on code authoring with R. That is why we also bring you native support for the R language on Apache Spark. Both through notebook and Spark Job definitions, users can author and run code with SparkR and SparklyR. Library management capabilities for R allow installation of R libraries incl. Tidyverse, so that data scientists can use familiar Spark and R interfaces to process data and develop machine learning models. We hope you enjoy the added flexibility of using R with Apache Spark in Microsoft Fabric.
