Introduction

In today's rapidly evolving technological landscape, transparency has become a crucial requirement in various industries. This is particularly evident in sectors such as finance, services, and government institutions, where stakeholders demand greater visibility and understanding of business processes. Additionally, new legislation, such as the General Data Protection Regulation (GDPR) in the Eurozone, and proposed acts related to artificial intelligence (AI), further emphasize the need for transparency in the deployment and automation of AI solutions.

Importance of Transparency in Business Processes

Transparency plays a critical role in ensuring accountability, trust, and compliance within business processes. It enables stakeholders to understand and verify the logic behind decisions made by AI systems. This level of visibility is particularly important when it comes to high-stakes applications, such as access to public services, education, employment, and law enforcement. Transparency provides not only a clearer understanding of the decision-making process but also ensures that potential biases and risks are assessed and managed appropriately.

The Emergence of Transparency in Artificial Intelligence

The increasing demand for transparency in business processes, coupled with new legislation, has led to the emergence of a transparent machine learning approach. Unlike the traditional black-box approach commonly associated with machine learning, transparent machine learning focuses on using inherently transparent models that can be easily inspected and understood. This approach allows businesses to author and evaluate models directly, with a focus on transparency and explainability.

The Difference Between General Machine Learning Approach and Transparent Machine Learning Approach

The general machine learning approach prioritizes accuracy and often treats models as black boxes. On the other HAND, the transparent machine learning approach places a higher emphasis on transparency and explainability. In the general case, explainability is achieved through complementary AI solutions, while transparent machine learning models are intrinsically explainable. Additionally, governance plays a significant role in the two approaches, with the general case being governed by data science teams, while transparent machine learning embraces a business-centric governance model.

Evaluating Transparent Machine Learning Models

When evaluating transparent machine learning models, it is essential to strike a balance between transparency and accuracy. While transparent models may sacrifice some accuracy, they offer the benefit of being inspectable and understandable. Transparent models allow stakeholders to assess the rationale, biases, and risks associated with AI-driven decisions. By enabling a deeper understanding of the decision-making process, transparent machine learning models contribute to improved trust, compliance, and accountability.

The Role of Governance in Transparent Machine Learning

In transparent machine learning, governance takes on a business-centric perspective. Instead of being solely the responsibility of data science teams, governance is shared with business analysts. This approach empowers business analysts to author and deploy transparent models directly into production. By allowing those closest to the business processes to make decisions about model authoring and deployment, governance becomes better aligned with the specific needs and requirements of the organization.

Transforming Transparent Machine Learning Models into Decision Models

One significant AdVantage of transparent machine learning is the ability to transform transparent models into decision models, specifically into decision tables. This transformation allows businesses to leverage existing decision management or business rules management systems (BRMS). By converting transparent models into decision tables, organizations can combine the benefits of transparency with familiar decision modeling paradigms. This enables business analysts to easily inspect, author, and evaluate transparent models within existing decision management workflows.

Demo: Applying Transparent Machine Learning to a Predictive Model

To demonstrate the application of transparent machine learning, we will use the famous "edu" dataset. This dataset aims to predict whether an individual's income exceeds a certain threshold. We will employ the AI Explainability 360 toolkit and machine learning algorithms to produce a rule set predictive model. By leveraging the transparency of this model, business analysts can gain insights into its inner logic and make informed decisions regarding its further evaluation and deployment.

Demo: Transforming a Transparent Machine Learning Model into a Decision Model

Building upon the rule induction model generated in the previous demo, we will now transform it into a decision model, more specifically into a DMN decision table. Using a command-line utility, we convert the rule set PMML model into a DMN decision table format. This enables us to easily inspect, author, and evaluate the resulting decision table. By leveraging the capabilities of DMN decision tables, we can enhance the transparency and understandability of the model, allowing for more effective stakeholder engagement.

Conclusion

Transparent machine learning offers significant benefits in terms of accountability, trust, and compliance in business processes. By embracing transparency, organizations can address stakeholder demands, comply with legislation, and mitigate risks associated with AI-driven decision-making. The transparent machine learning approach empowers business analysts to author and deploy models, leveraging existing decision management systems. By combining transparency with familiar decision modeling paradigms, organizations can improve the overall explainability and governance of AI systems.
