    “Essentially, all models are wrong, …but some are useful.”

    GEORGE BOX

    FAMOUS TWENTIETH CENTURY STATISTICIAN

    Executive Summary: Machine Learning Algorithms Embedded in Data Management Platforms

    The era of “big data” and the “cloud” is driving enterprises to change. Just to keep pace, executives

    and technologists must learn skills and implement new practices that leverage non-traditional data

    sources and technologies. As a result of sharing their “digital exhaust”, customers have increased

    expectations of the enterprises that service them. Customers expect improved customer interactions

    and greater perceived value. With big data and the cloud, enterprises have the opportunity to satisfy

    these new expectations. Cloud, competition, big data analytics and next-generation “predictive”

    applications enable enterprises to achieve new goals, and deliver greater insights and better

    outcomes. Traditional business intelligence and analytics approaches do not deliver these insights and

    simply cannot satisfy the ever-growing customer expectations in this new world order created by big

    data and the cloud.

    Unfortunately, with big data, as data volumes grow in velocity (speed of delivery), volume (size), and

    variety (data types), new problems emerge. Data volumes can quickly become unmanageable and

    immovable. Scalability, security, and information latency become new issues. In addition, dealing with

    unstructured text, sensor data, or spatial and graph data each introduce new analytics complexities.

    Traditional advanced analytics tools, now often referred to as machine learning tools, inherently have

    several information technology weak points: the need for data extracts and data movement, data

    duplication resulting in no single-source of truth, data security concerns, the need for separate and

    often multiple analytical tools (commercial and open source) and languages (SAS, R, SQL, Python,

    SPSS, etc.). These weak points become particularly egregious during the deployment phase when the

    worlds of data analysis and information management collide.

    Traditional machine learning processes typically start with a representative sample or subset of the

    data that is exported to separate analytical servers and tools (SAS, R, Python, SPSS, etc.) that have

    been often designed for data scientists. The analytics they perform range from simple descriptive

  • 2 | ORACLE MACHINE LEARNING

    statistical analysis to advanced, predictive, and prescriptive analytics, including machine learning. If a

    data scientist builds a predictive model that is determined to be useful and valuable, Information

    Technology (IT) organizations needs to be involved to figure out deployment. It’s at that point that

    enterprise deployment and application integration issues become a significant challenge.

    In this scenario, to make predictions on larger datasets maintained within a data warehouse, predictive

    models—and all their associated data preparation and transformation steps—must somehow be

    translated to SQL and recreated inside the database, or translated to Java for execution in an

    application. This model translation phase introduces tedious, time consuming and expensive manual

    coding steps from the original statistical language (SAS, R, and Python) into SQL and Java. DBAs and

    IT must somehow “productionize” these separate machine learning models within or alongside the

    database and/or data warehouse for distribution throughout the enterprise. This is where many

    advanced analytics projects fail. Some vendors will charge for specialized products and options for just

    the predictive model deployment capability. Add Hadoop, sensor data, tweets, and expanding big data

    reservoirs, and the entire data-to-actionable-insights process becomes more challenging.

    Not with Oracle. Oracle delivers a big data and analytics platform that eliminates the traditional extract,

    move, load, prepare and analyze, export, move, import workflow. With Oracle Database 19c and

    Oracle Machine Learning, big data management and machine learning are combined and designed

    into the data management platform from the beginning. Through multiple decades of R&D investment

    in developing the industry’s leading data management platform, Oracle SQL, Big Data SQL, Cloud

    SQL, Oracle Exadata, Oracle Big Data Service and integration with open source R, Oracle provides a

    seamlessly integrated data analytics platform in Oracle Database. Now, Oracle Database becomes a

    “Thinking Database.”

    Oracle Machine Learning Platform compared to traditional machine learning reduces the time from data to

    model deployment from weeks to hours.

    The Oracle vision has two objectives: 1) make big data and analytics simple for a range of users

    involving a wide variety of data in different compute environments, and 2) make analytics results

    simple to deploy, whether as a service or in an application or dashboard.

    Oracle Machine Learning offers a library of powerful in-database algorithms and integration with open

    source R that together can solve a wide variety of business problems. These algorithms are accessible

    via SQL, R, or user interface. Oracle Machine Learning, supported by the Oracle Advanced Analytics

    option to Oracle Database 19c Enterprise Edition, extends the database into an enterprise-wide

    analytical platform for data-driven problems such as churn prediction, customer segmentation, fraud

    and anomaly detection, identifying cross-sell and up-sell opportunities, market basket analysis, text

    mining, and sentiment analysis. Oracle Machine Learning empowers data scientists and analysts to

    extract knowledge, discover new insights, and make data-driven predictions—working directly with

    large data volumes in Oracle Database and Big Data environments.

    Data scientists and analysts have choice and flexibility in how they interact with Oracle Machine

    Learning. Oracle Data Miner is an Oracle SQL Developer extension designed as an easy-to-use “drag

    and drop” workflow user interface that automates many of the steps in the machine learning process.

    Oracle SQL Developer is a free, integrated development environment that simplifies database

    development and management of Oracle Database in both traditional and Cloud deployments. When

    satisfied with their analytical workflows, Oracle Data Miner users can share their workflows with other

    analysts and/or generate SQL scripts to hand to their IT organization to accelerate solution

    deployment. Oracle Data Miner also provides a PL/SQL API for workflow scheduling and automation.

    Oracle Machine Learning for R is supported by Oracle R Enterprise, a component of the Oracle

    Advanced Analytics Option to Oracle Database. OML4R makes the open source R statistical

    programming language and environment ready for the enterprise and big data. Designed for problems

    involving both large and small volumes of data, OML4R integrates R with Oracle Database. Data

    scientists and broader R users can take advantage of the R ecosystem on data managed by Oracle

    Database. R provides a rich ecosystem of software packages for data manipulation, graphics,

    statistical functions, and machine learning algorithms. Oracle Machine Learning for R extends R’s

    capabilities through three primary areas: transparent access and manipulation of database data from R

    through overloaded R function-to-SQL translation, in-database machine learning algorithms, ease of

    deployment using embedded R execution.
