Recipes
A recipe is Adobe's term for a model specification and is a top-level container representing a specific machine learning, AI algorithm or ensemble of algorithms, processing logic, and configuration required to build and execute a trained model and hence help solve specific business problems.
Model
A model is an instance of a machine learning recipe that is trained using historical data and configurations to solve for a business use case.
Training
Training is the process of learning patterns and insights from labeled data.
Trained Model
A trained model represents the executable output of a model training process, in which a set of training data was applied to the model instance. A trained model will maintain a reference to any intelligent web service that is created from it. The trained model is suitable for scoring and creating an intelligent web service. Modifications to a trained model can be tracked as a new version.
Scoring
Scoring is the process of generating insights from data using a trained model.
Service
A deployed service exposes functionality of an artificial intelligence, machine learning model or advanced algorithm through an API so that it can be consumed by other services or applications to create intelligent apps.
The following chart outlines the hierarchical relationship between Recipes, Models, Training Runs, and Scoring Runs.

Understanding Data Science Workspace

With Data Science Workspace, your data scientists can streamline the cumbersome process of uncovering insights in large datasets. Built on a common machine learning framework and runtime, Data Science Workspace delivers advanced workflow management, model management, and scalability. Intelligent services support re-use of machine learning recipes to power a variety of applications created using Adobe products and solutions.

One-stop data access

Data is the cornerstone of AI and machine learning.
Data Science Workspace is fully integrated with Adobe Experience Platform, including the Data Lake, Real-time Customer Profile, and Unified Edge. Explore all your organizational data stored in Adobe Experience Platform at once, along with common big data and deep learning libraries, such as Spark ML and TensorFlow. If you don't find what you need, ingest your own datasets using the XDM standardized schema.

Prebuilt machine learning recipes

Data Science Workspace includes prebuilt machine learning recipes for common business needs, like retail sales prediction and anomaly detection, so data scientists and developers don't have to start from scratch. Currently three recipes are offered, product purchase prediction , product recommendations , and retail sales .
If you prefer, you can adapt a prebuilt recipe to your needs, import a recipe, or start from scratch to build a custom recipe. However you begin, once you train and hyper-tune a recipe, creating a custom intelligent service doesn't require a developer - just a few clicks and you're ready to build a targeted, personalized digital experience.

Workflow focused on the data scientist

Whatever your level of data science expertise, Data Science Workspace helps simplify and accelerate the process of finding insights in data and applying them to digital experiences.

Data exploration

Finding the right data and preparing it is the most labor-intensive part of building an effective recipe. Data Science Workspace and Adobe Experience Platform will help you get from data to insights more quickly.
On Adobe Experience Platform, your cross-channel data is centralized and stored in the XDM standardized schema, so data is easier to find, understand, and clean. A single store of data based on a common schema can save you countless hours of data exploration and preparation.
As you browse, use R, Python, or Scala with the integrated, hosted Jupyter Notebook to browse the catalog of data on Platform. Using one of these languages, you can also take advantage of Spark ML and TensorFlow. Start from scratch, or use one of the notebook templates provided for specific business problems.
As part of the data exploration workflow, you can also ingest new data or use existing features to help with data preparation.

Authoring

With Data Science Workspace, you decide how you want to author recipes.
  • Save time by browsing for a prebuilt recipe that addresses your business needs, which you can use as is or configure to meet your specific requirements.
  • Create a recipe from scratch, using the authoring runtime in Jupyter Notebook to develop and register the recipe.
  • Upload a recipe authored outside Adobe Experience Platform into Data Science Workspace or import recipe code from a repository, such as Git, using the authentication and integration available between Git and Data Science Workspace.

Experimentation

Data Science Workspace brings tremendous flexibility to the experimentation process. Start with your recipe. Then create a separate instance, using the same core algorithm paired with unique characteristics, such as hyper-tuning parameters. You can create as many instances as you need, training and scoring each instance as many times as you want. As you train them, Data Science Workspace tracks recipes, recipe instances, and trained instances, along with evaluation metrics, so you don't have to.

Operationalization

When you're happy with your recipe, it's just a few clicks to create an intelligent service. No coding required - you can do it yourself, without enlisting a developer or engineer. Finally, publish the intelligent service to Adobe IO and it's ready for your digital experience team to consume.

Continuous improvement

Data Science Workspace tracks where intelligent services are invoked and how they're performing. As data rolls in, you can evaluate intelligent service accuracy to close the loop, and retrain the recipes as needed to improve performance. The result is continuous refinement in the precision of customer personalization.

Access to new features and datasets

Data scientists can take advantage of new technologies and datasets as soon as they are available through Adobe services. Through frequent updates, we do the work of integrating datasets and technologies into the platform, so you don't have to.

Access control in Data Science Workspace

Access control for Experience Platform is administered through the Adobe Admin Console . This functionality leverages product profiles in Admin Console, which link users with permissions and sandboxes. See the access control overview for more information.
In order to use Data Science Workspace, the "Manage Data Science Workspace" permission must be enabled.
The following table outlines the effects of having this permission enabled or disabled:
Permission

API and UI access to all services within Data Science Workspace are disabled. While disabled, routing to the Data Science Workspace Models and Services pages are prevented.

Security and peace of mind

Securing your data is a top priority for Adobe. Adobe protects your data with security processes and controls developed to help comply with industry-accepted standards, regulations, and certifications.
Security is built into software and services as part of the Adobe Secure Product Lifecycle. To learn about Adobe data and software security, compliance, and more, visit the security page at https://www.adobe.com/security.html.

Sandbox support

Sandboxes are virtual partitions within a single instance of Experience Platform. Each Platform instance supports one production sandbox and multiple non-production sandboxes, each maintaining its own library of Platform resources. Non-production sandboxes allow you to test features, run experiments, and make custom configurations without impacting your production sandbox. For more information on sandboxes, see the sandboxes overview .
Currently, Data Science Workspace has a couple sandbox limitations:
  • Compute resources are shared across the production sandbox and non-production sandboxes. Isolation for production sandboxes is set to be provided in the future.
  • Scala/Spark and PySpark workloads for both notebooks and recipes are currently only supported in the production sandbox. Support for non-production sandboxes is set to be provided in the future.

Data Science Workspace in action

Predictions and insights provide the information you need to deliver a highly personalized experience to each customer who visits your web site, contacts your call center, or engages in other digital experiences. Here's how your day-to-day work happens with Data Science Workspace.

Define the problem

It all starts with a business problem. For example, an online call center needs context to help them turn a negative customer sentiment positive.
There's plenty of data about the customer. They've browsed the site, put items in their cart, and even placed orders. They might have received emails, used coupons, or contacted the call center previously. The recipe, then, needs to use the data available about the customer and their activities to determine propensity to buy and recommend an offer that the customer is likely to appreciate and use.
At the time of the call center contact, the customer still has two pairs of shoes in the cart, but removed a shirt. With this information, the intelligent service might recommend that the call center agent offer a coupon for 20% off on shoes during the call. If the customer uses the coupon, that information is added to the dataset and the predictions become even better the next time the customer calls.

Explore and prepare the data

Based on the business problem defined, you know the recipe should look at all the customer's web transactions, including site visits, searches, page views, links clicked, cart actions, offers received, emails received, call center interactions, and so on.
A data scientist typically spends up to 75% of the time required to create a recipe exploring and transforming the data. Data often comes from multiple repositories and is saved in different schemas - it must be combined and mapped before it can be used to create a recipe.
If you're starting from scratch or configuring an existing recipe, you begin your data search in a centralized and standardized data catalog for your organization, which simplifies the hunt considerably. You might even find that another data scientist in your organization has already identified a similar dataset, and choose to fine-tune that dataset rather than start from scratch. All the data in Adobe Experience Platform complies with a standardized XDM schema, eliminating the need to create a complex model for joining data or obtain help from a data engineer.
If you don't immediately find the data you need, but it exists outside Adobe Experience Platform, it's a relatively simple task to ingest additional datasets, which will also transform into the standardized XDM schema. You can use Jupyter Notebook to simplify data pre-processing - possibly starting with a notebook template or a notebook you've used previously for propensity to buy.

Author the recipe

If you already found a recipe that meets all your needs, you can move on to experimentation. Or, you can modify the recipe a bit or create one from scratch - taking advantage of the Data Science Workspace authoring runtime in Jupyter Notebook. Using the authoring runtime ensures that you can both use the Data Science Workspace training and scoring workflow and convert the recipe later so it can be stored and reused by others in your organization.
You can also import a recipe in to Data Science Workspace and take advantage of the experimentation workflows as you create your intelligent service.

Experiment with the recipe

With a recipe that incorporates your core machine learning algorithms, many recipe instances can be created with a single recipe. These recipe instances are referred to as models. A model requires training and evaluation to optimize its operating efficiency and efficacy, a process typically consisting of trial and error.
As you train your models, training runs and evaluations are generated. Data Science Workspace keeps track of evaluation metrics for each unique model and their training runs. Evaluation metrics generated through experimentation will allow you to determine the training run that performs best.
Visit this section for tutorials on how to train and evaluate models in Data Science Workspace.

Operationalize the model

When you've selected the best trained recipe to address your business needs, you can create an intelligent service in Data Science Workspace without developer assistance. It's just a couple of clicks - no coding required. A published intelligent service is accessible to other members of your organization without the need to recreate the model.
A published intelligent service is configurable to automatically train itself from time to time using new data as they become available. This ensures your service maintains its efficiency and efficacy as time continues.
