Study Notes

Data Analytics Stages

Three stages of data analytics exist: descriptive, predictive, and prescriptive.
Descriptive analytics involves analyzing past data to identify patterns and trends.
Predictive analytics uses past data to predict future outcomes.
Prescriptive analytics suggests actions to improve future outcomes.

Descriptive Analytics and Data Visualization

Descriptive analytics analyzes past data to show clear patterns and trends.
Data visualization tells an interesting, insightful story, presenting data intuitively and accurately.
Data visualization ensures accurate and non-misleading interpretation, avoiding statistical deception.

Role-playing Exercise (Health Insurance)

Managers are tasked with managing a health insurance provider for senior citizens (66+).
Health insurance allows individuals to contribute to future healthcare costs. The U.S. typically covers all medical costs and some have Medicaid, similar to the French Assurance maladie. In comparison France also has a mutuelle model. The French mutuelle covers large healthcare costs.
Members' healthcare costs are to be paid, and they must have fewer medical needs.

US National Medical Expenditure Survey (NMES) Dataset

The dataset comprises 4,406 senior citizens (66+).
Variables include hospital stays, self-perceived health, chronic conditions, activity level, region, age, race, gender, marital status, education, income, employment status, private insurance, and Medicaid coverage.
75% of the sample has private insurance, 9% have Medicaid, and 15% have no insurance.

Al-powered Descriptive Analytics with Microsoft Excel

The video discusses Excel Al, a tool for effortless data analysis.

Predictive Analytics

Predictive analytics analyzes past data to predict the future, assuming the future resembles the past.
The primary focus is accurate prediction of the target outcome, but factors leading to that outcome are not necessarily causal.
Predictive analytics can be used to prioritize tasks, anticipate events with minimal control, or establish benchmarks for prescriptive analysis.
Automation (AutoML) frequently yields strong results in predictive analysis.

Meaningful Explanations for Prescriptive Analytics

Prescriptive analysis improves target outcomes rather than reproducing them.
The objective is to interpret input factors' influence on outcomes to guide interventions.
It is more valuable to have a clear interpretation of why a model is doing something rather than an accurate answer that does not reveal the inner workings.

Explainable AI (XAI)

XAI focuses on human-understandable explanations of Al's processes and results.
It aims to simplify internal model operations and remove misconceptions for a better understanding.
XAI can make certain models easier to understand and apply in various real-world contexts, and be more relatable to users.

Stakeholders of XAI

Stakeholders include managers, users, developers of Al (programmers, analysts, engineers), and external regulators.
Stakeholders have specific goals for XAI, including algorithmic transparency, realistic representation of data, ethical responsibility, and prescriptive actionability.

Accumulated Local Effects (ALE) Plots

ALE plots display the influence of variables on average predictions, utilizing various visualizations that illustrate how input variables affect predicted values, with details concerning distribution and prevalence.

Actionable Explanation Process

Concepts related to the ultimate goal are categorized based on their controllability and importance.
Data analysis methods are used based on the specified concepts.
Concepts are categorized again post-analysis and grouped according to actionable explanation types.

Key Attributes of Concepts in XAI Explanation

Concepts are classified in terms of their relevance, controllability, and if they are relevant or not.
Relevance covers concepts that have an ultimate impact for which managers should take action.
Controllability refers to concepts controlled by managers, but non-controllable concepts can be studied for anticipation.

Relevance of Concepts

Ultimate concepts are the primary target or label in supervised machine learning.
Relevant concepts impact the ultimate concept in a measurable way.
Irrelevant concepts have minimal impact on the ultimate concept.
Relevant and not relevant concepts are studied with implications for actions the manager should take based on this knowledge.

Controllability of Concepts

High control denotes considerable managerial influence over concept values.
Low control implies limited managerial influence, as other external factors play a significant role.
No control indicates no managerial influence over values.

Managerial Implications of Controllability

High control suggests a managerial responsibility to shape the target concept in a favorable direction.
Low/no control emphasizes the need for observation, anticipation, and proactive responses to changes in the concept.

Evaluation of the Teacher

Comments should be inclusive of liked aspects, areas requiring improvement, and general classroom management.
Separated evaluation links will be used for homework and instructor sessions. Comments on homework are not to be included.

Conclusion

Data analytics stages (descriptive, predictive, prescriptive) provide increasingly valuable insights for managers.
XAI (Explainable AI) helps managers understand contributing factors to a machine learning model's predictions and helps action plans.
Actionable explanations will aid managers to focus analysis results allowing them to respond to the greatest desired impact.
