A deductive approach to text analytics through construction and validation of categorization models.

In this session, we will introduce participants to a powerful deductive approach in text analytics using categorization models.  Such an approach allows analysts and researchers to identify the degree to which specific concepts or topics are present within a large volume of documents. This approach requires one to build dictionaries with multiple categories and subcategories containing words, word patterns, phrases and rules that are then used to extract specific content of interest. Sentiment analysis is a well-known example of such an approach, but we will see that there are many more applications of categorization models. Dr. Normand Peladeau will demonstrate how to build, validate, and deploy a categorization dictionary to answer specific research questions or test hypotheses.

Analyzing Multidimensional Data with Ease

Presented by: Kevin Potcner

As data becomes more available across almost every industry, analyses of that data require more than the 1-sample and 2-sample inferential analysis techniques traditionally taught in the standard one and two semester statistics courses. For students to be prepared for today’s job market, their analysis toolbox needs to be expanded to include tools that are much more powerful capable of finding patterns and relationships across a large number of variables. The presenter will illustrate how JMP’s interactive point-and-click environment makes it easy to explore highly dimensional data intuitively with dynamic visualizations and advanced data mining and predictive modeling capabilities.

1) IBM Large Data Forecasting Toolkit (40min)

Forecasting for large numbers of related time series is a common need across many domains. E.g., in supply chains it may be necessary to forecast demand for up to billions of product-store time series. In process industries production processes can be instrumented with thousands of sensors, producing large numbers of time series with complex relationships. Handling the scale for fine-grained forecasting while supporting a variety of forecasting components (including deep learning techniques) and their automated selection and evaluation is a challenging task, not yet fully addressed in existing systems. We present a toolkit for this purpose and describe its design, components, features, and application along with benchmarks across data sets for different techniques (including DL and traditional forecasting techniques).  

2) Smarter Resource and Operations Management (40min)

AI powered analytics and automation is critical for realizing enhanced productivity and investment return. In this talk, we present SROM, a toolkit suite that provides out-of-the-box purpose built machine learning and optimization pipelines targeted at core functions of the industry. This helps accelerate and operationalize AI towards building custom applications with data from assets and processes.  The Intelligent Assets and Operations toolkit is focused on advanced techniques for anomaly detection, failure pattern analysis, cohort analysis, and enhanced pipelines for rapid authoring, training and deployment of Industry 4.0 applications. The second toolkit in the suite, referred to as Situational Awareness toolkit, brings together multi-model data and domain semantics to maintain an active semantic representation of the cyber-physical plant, reflecting the state and health of operations for actionable awareness. The Intelligent System and Optimization toolkit provides optimization techniques which couple machine learning (including regression, deep learning) with novel optimization techniques for providing data driven decision making. We provide a description of each of the toolkits along with use cases that demonstrate the application of these capabilities in real-world situations.

3) IBM Decision Optimization – New Highlights (40min)

The first part of the workshop will focus on the IBM Decision Optimization offerings.  The upcoming version of CPLEX Optimization Studio will offer not only performance improvements, but also a number of new features, including:

– Black-box optimization in CP Optimizer.

– Database support in OPL

– A new CPLEX MIP emphasis mode with extreme focus on primal performance

We will describe these features and their usage. We will also highlight the recent evolutions of Cloud Pak for Data, the IBM platform for the development and deployment of Machine Learning and Decision Optimization models.
