The Predictive Model Markup Language PMML delivers the necessary representational power and agility for solutions to be quickly and easily exchanged between systems, allowing for predictions to move at the speed of business. First, it lists the variables which are to be output as the scored values after applying the model to a dataset.

Using various attributes, this allows a model to predict multiple variables and automatically define those variables as some standard features of the predicted value. These features include the predicted value, predicted category, probability of the winning category, probability of all other categories and others.

The second responsibility of the Output element is to post-process data. The model scores the data and passes on the predictions to the output element; one can then define operations to be applied to those values to further process them and output the post-processed data.

It is not uncommon that a model is fit and then transformed into a PMML representation, however missing any information about any post-processing the modeler would have wished. Practical applications of a model may well require extra operations which are designed by the modeler, not automatically generated.

We will look at just such a scenario where after a model is made, one wishes to add new Output nodes to the pre-fit model to define new features or new processing information to be included in the PMML representation. The values to be output are listed as OutputField child elements of the Output element. All the information in those elements are contained in its attributes. The most commonly used are the attributes nameoptypedataTypefeature and value.

The name is obviously the name of the field which is defined. The optype and dataTypeas usual, define the kind of variable being defined; is is a string or integer, is it a numeric value or a categorical value?

The feature attribute defines what the output actually is and how to calculate it. Some possible output methods are predefined as an attribute value.

For example, if the feature is predictedValue then the output field is the predicted value of the model. If the feature is probabilitythe output is the probability of the winning category. This is automatically defined so that the method to calculate probability does not have to be defined.

If the feature is probability and the value attribute is one of the allowed values of the categorical variable being predicted, the field is the probability of that particular value. Often there are calculations desired on the model predictions which are not simply predefined as a possible value of the feature attribute. In such a case, feature is set to transformedValue and an expression is given as a child element.

That expression is used to make the calculation desired. The model now outputs just one variable, the predicted length. Now we wish to output not just the predicted length but several post-processed values of that predicted value.

We show this using several example transformations for illustration, they do not necessarily make sense for a simple iris dataset.

The first step is to create the OutputField element to add inside the Output element. The pmml package provides a function, makeOutputNodes, which makes creating such elements easily. It can be used to make multiple OutputField nodes directly as well.

Note that the values of the parameters are given one-by-one in a list format.

The OutputField nodes are created:. Next we have to insert these new nodes inside the Output node. The pmml package provides a helper function to do just that; addOutputField. One can also use the function to add a single OutputField element at a time. To show how the function works, first we add these hypothetical nodes right after the predicted field.

With multiple such fields it might be better to predefine lists with the names and attributes of the new elements but here, we just do it in one line.If someone asked you if you had used predictive analytics today, you would probably answer "no". But the truth is you probably use it on a daily basis without knowing it. Every time you swipe your credit card or use it online, a predictive analytic model checks the probability of that transaction being fraudulent.

If you rent DVDs online, chances are a predictive analytic model recommended a particular movie to you. The fact is predictive analytics is already an integral part of your life and its application is bound to assist you even more in the future. As sensors in bridges, buildings, industrial processes, and machinery generate data, predictive solutions are bound to provide a safer environment in which predictions alert you to potential faults and problems before they actually happen.

Sensors are also used to monitor humans, as in the case of patients in an Intensive Care Unit. But can predictive analytics alone make sense of it all? It depends. Open standards most definitely need to be part of the equation. For you to fully benefit from predictive solutions and data analysis, systems and applications need to be able to exchange information easily by following standards. PMML allows for predictive analytic models to be shared between applications and systems.

The adoption of PMML by the major analytic vendors is a great example of companies embracing interoperability. PMML is here to shape the world of predictive analytics and therefore make the predictive world a better place for you. PMML is the de facto standard language used to represent data mining models.

Predictive analytic models and data mining models are terms used to refer to mathematical models that use statistical techniques to learn patterns hidden in large volumes of historical data. Predictive analytic models use the knowledge acquired during training to predict the existence of known patterns in new data.

PMML allows you to easily share predictive analytic models between different applications. Therefore, you can train a model in one system, express it in PMML, and move it to another system where you can use it to predict, for example, the likelihood of machine failure.

PMML is the brain child of the Data Mining Group, a vendor-led committee composed of commercial and open source analytic companies see Related topics for a link.We recently released Neighbr, a package for performing k-nearest neighbor classification and regression.

Highlights of version 1. In this blog post, we will provide some examples of how to use neighbr to create knn models. First, load necessary libraries and set the seed and number display options. This example shows using squared euclidean distance with 3 neighbors to classify the Species of flowers in the iris dataset. Each training instance consists of 4 features and 1 class variable. The categorical target is predicted by a majority vote from the closest k neighbors. It is possible to predict categorical and continuous targets simultaneously, as well as to return the IDs of closest neighbors of a given instance.

In the next example, an ID column is added to the data for ranking, and Petal. Width is used as a continuous target. By default, the prediction for the continuous target is calculated by averaging the closest k neighbors. The ranked neighbor IDs are returned along with the categorical and continuous targets, with neghbor1 being the closest in terms of distance. If a similarity measure were being used, neighbor1 would be the most similar.

It is possible to get neighbor ranks without a target variable. The package supports logical features, to be used with an appropriate similarity measure. This example demonstrates predicting a categorical target and ranking neighbors for the HouseVotes84 dataset from the mlbench package. In this example, the factor features are converted to numeric vectors. Distance measures are used for vectors with continuous elements. Similarity measures are used for logical vectors.

The comparison measures used in neighbr are based on those defined in the PMML standard. Functions in neighbr can be used to calculate distances or similarities between vectors directly:.

Building a model is generally not the end of the project. Even if the purpose of the model is to increase knowledge of the data, the knowledge gained will need to be organized and presented in a way that the customer can use it.

Depending on the requirements, the deployment phase can be as simple as generating a report or as complex as implementing a repeatable data science process.

In many cases, it will be the customer, not the data analyst, who will carry out the deployment steps. For example, a credit card company may want to deploy a trained model or set of models e.

However, even if the analyst will not carry out the deployment effort it is important for the customer to understand up front what actions will need to be carried out in order to actually make use of the created models. In general, there is four way of deploying the models in data science. An example of using a data mining tool Orange to deploy a decision tree model.

An example of using a programming language Visual Basic to deploy a regression model. PMML is an XML-based language used to define statistical and data science models and to share these between compliant applications. It defines a standard not only to represent data-science models, but also data handling and data transformations pre and post processing.

PMML eliminates the need for custom model deployment and allows for the clear separation of model development and model deployment tasks. The following data science methods are supported by PMML. Pre-Processing Data Dictionary: Allows for the explicit specification of valid, invalid and missing values.

Mining Schema: Used to define the appropriate treatment to be applied to missing and invalid values. Transformations: Allow for variable discretization, normalization, and mapping with handling of missing and default values. Built-in Functions: Arithmetic expressions, handling of date and time as well as strings.

Models PMML allows for several predictive modeling techniques to be fully expressed. Header : contains general information about the PMML document, such as copyright information for the model, its description, and information about the application used to generate the model such as name and version.

It also contains an attribute for a timestamp which can be used to specify the date of model creation. Data Dictionary : contains definitions for all the possible fields used by the model. It is here that a field is defined as continuous, categorical, or ordinal. Depending on this definition, the appropriate value ranges are then defined as well as the data type such as, string or double.

Predictive Model Markup Language (PMML)

Data Transformations : transformations allow for the mapping of user data into a more desirable form to be used by the mining model. PMML defines several kinds of simple data transformations. Normalization: map values to numbers, the input can be continuous or discrete. Discretization: map continuous values to discrete values. Value mapping: map discrete values to discrete values. Functions: derive a value by applying a function to one or more parameters.

Aggregation: used to summarize or collect groups of values. Model : contains the definition of the data science model. For example a fee-forward neural network is represented in PMML by a "NeuralNetwork" element which contains attributes such as:. Mining Schema : the mining schema lists all fields used in the model. This can be a subset of the fields as defined in the data dictionary.

It contains specific information about each field, such as:. Name attribute name : must refer to a field in the data dictionary Usage type attribute usageType : defines the way a field is to be used in the model.

Typical values are: active, predicted, and supplementary.

Predicted fields are those whose values are predicted by the model.PMML "provides applications a vendor-independent method of defining models so that proprietary issues and incompatibilities are no longer a barrier to the exchange of models between applications. It allows users to develop models within one vendor's application, and use other vendors' applications to visualize, analyze, evaluate or otherwise use the models.

Ask and you shall receive quotes

Previously, this was very difficult, but with PMML, the exchange of models between compliant applications is now straightforward PMML is complementary to many other data mining standards. A PMML document provides a non-procedural definition of fully trained or parameterized analytic models with sufficient information for an application to deploy them. By parsing the PMML using any standard XML parser the application can determine the types of data input to and output from the models, the detailed forms of the models, and how, in terms of standard data mining terminology, to interpret their results.

Version 1. This is by no means a comprehensive set, and our expectation is that this standard will evolve very rapidly to cover a robust collection of model types. The purpose of publishing this limited set is to demonstrate the fundamentals of PMML with a realistic and useful "initial value" of what will emerge as a comprehensive and rich collection of modeling capabilities. As you will see, our dictionary elements are very primitive.

We anticipate and look forward to subsequent versions of this standard introducing optimizations, such as bit vector expansions of categorical fields or log transforms of continuous fields, but we believe that before such optimizations can be included it is necessary to agree on minimally sufficient infrastructure.

Another goal is to enable combined, collaborative use of a potentially very large number of individual models and proactive administration of collections of models based on business needs as well as mathematical principles.

We believe these capabilities are fundamental to effective deployment of analytic models in commercial application domains.

PMML, or something very like it, is urgently needed to satisfy dramatically increased requirements for statistical and data mining tools and technologies in business systems. As part of W3C affiliation we expect to increase group membership to include other major players in the data mining tools and applications space.

A version 0. Hallstrom is available for review. Magnify is providing an open source architecture for the PMML. The authors "introduce a markup language based upon XML for working with the predictive models produced by data mining systems. It provides a flexible mechanism for defining schema for predictive models and supports model selection and model averaging involving multiple predictive models. It has proved useful for applications requiring ensemble learning, partitioned learning, and distributed learning.
