Decision tree ensembles are widely used in critical domains, making robustness and sensitivity analysis essential to their trustworthiness. We study the feature sensitivity problem, which asks whether an ensemble is sensitive to a specified subset of features -- such as protected attributes -- whose manipulation can alter model predictions. Existing approaches often yield examples of sensitivity that lie far from the training distribution, limiting their interpretability and practical value. We propose a data-aware sensitivity framework that constrains the sensitive examples to remain close to the dataset, thereby producing realistic and interpretable evidence of model weaknesses. To this end, we develop novel techniques for data-aware search using a combination of mixed-integer linear programming (MILP) and satisfiability modulo theories (SMT) encodings. Our contributions are fourfold. First, we strengthen the NP-hardness result for sensitivity verification, showing it holds even for trees of depth 1. Second, we develop MILP-optimizations that significantly speed up sensitivity verification for single ensembles and for the first time can also handle multiclass tree ensembles. Third, we introduce a data-aware framework generating realistic examples close to the training distribution. Finally, we conduct an extensive experimental evaluation on large tree ensembles, demonstrating scalability to ensembles with up to 800 trees of depth 8, achieving substantial improvements over the state of the art. This framework provides a practical foundation for analyzing the reliability and fairness of tree-based models in high-stakes applications.

AI technologies like ChatGPT are necessitating a fundamental overhaul of our educational systems and institutions. Getting the right answers to predetermined tests is no longer sufficient in an age where AI can access, integrate, and recite knowledge billions if not trillions of times faster than the human mind. So, what are the skills, capabilities, and experiences that our students and citizens will need to prosper in an age where personal and professional success will be based on the application, not the memorization and regurgitation, of knowledge? Let's continue that conversation here in Part II to define the requirements for humans to excel in creating organizational and societal value in a world dominated by AI and Big Data. Many organizations engage in a "wear'em down" decision-making process when dealing with wicked hard challenges with multiple opposing views.

As artificial intelligence systems play a bigger role in everyday life, they're changing the world of education, too. Here are four ways I believe these kinds of systems can be used to help students learn. Teachers are taught to identify the learning goals of all students in a class and adapt instruction for the specific needs of individual students. An AI system can observe how a student proceeds through an assigned task, how much time they take and whether they are successful. If the student is struggling, the system can offer help; if the student is succeeding, the system can present more difficult tasks to keep the activity challenging.

I use Neuroflash to write my articles because it helps me stay focused and tonality is persuasive. Neuroflash is an online tool that helps you improve your writing by providing feedback on your text. It uses cognitive neuroscience to help you understand how your reader will react to your words, and it provides guidance on how to improve your writing. Neuroflash has helped me improve my writing by helping me understand the impact of my words on my readers. It has also helped me stay focused when I am writing, and it has provided valuable feedback on my text.

The discovery phase is where we attempt to understand the data. It might require cleaning, transformation, integration. The following code snippet highlights the data preprocessing steps. The dataset contained null values, both numerical and categorical values. The categorical values were both nominal and ordinal.

As Data Science (DS) continues to be a growing field with promising prospects [1]-[3], it is attracting significant attention from many including learners of different learning backgrounds and applications areas. From a DS educator's perspective, the result is a very diverse cohort of learners. This typically includes (in no order) mathematicians, statisticians, operations researchers, computer scientists of all their colours, other scientists (e.g.

The welcome was given by University of Pittsburgh President Wesley Posvar. The conference cochairmen, Stellan Ohlsson and Jeff Bonar, also gave brief welcomes to the participants. The relatively small size of the conference, about 425 participants, was undoubtedly in part responsible for the congenial ambiance of the meeting. In addition to the opportunity to reunite with old friends, it was easy to establish new relationships with nearly everyone at the conference. With so many attendees from abroad (The Netherlands, Japan, Canada, West Germany, England, Sweden, France, and Hong Kong were all represented by speakers), the international flavor of the conference was well established.

Identifying generic, domain-independent tasks, formalizing task representation, elucidating the role of the task in eliciting domain-specific knowledge, and standardizing the design and development of expert systems then became the major research problems of the field. Knowledge specification, includes the task decomposition and the specification of the domain information types and knowledge bases. The task decomposition can be guided by selecting to reuse some of the previously identified task templates. Finally, during knowledge refinement, the models are validated through simulation on paper or with prototyping, and the knowledge bases are refined. Depending on how familiar the analyst is with the domain, these activities might have to be performed repeatedly, and subsequent activities might provide feedback for corrections or extensions to the products of earlier ones.
