What is Explainable AI?: How it Enhances Transparency and Accountability of AI Models

“Explainable AI is crucial to ensure trust and transparency in AI applications, enabling humans to understand and evaluate the decisions made by machines.”

This quote was said by IBM Watson, a provider of AI technologies and solutions.

1. Introduction on Explainable AI

Dramatic success in machine learning has led to a spurt of Artificial Intelligence (AI) applications. Continued advances promise to produce autonomous systems that will perceive, learn, decide, and act on their own.

However, the effectiveness of these systems is limited by the machine’s current inability to explain their decisions and actions to human users.as AI becomes more advanced, it also becomes increasingly complex and difficult to understand.

The lack of transparency and interpretability of AI models can raise concerns about ethical, legal, and social implications. To address these concerns, Explainable AI (XAI) has emerged as a crucial area of research in AI. In this context, explainability refers to the ability of AI systems to provide understandable and justifiable explanations for their decisions or predictions.

This has significant implications for AI ethics, accountability, and trust, and can also help to improve the performance and usability of AI systems.

2. Importance of Transparency and Accountability in AI

Transparency and accountability are crucial aspects of any technology, especially when it comes to artificial intelligence (AI). As AI is becoming increasingly complex and ubiquitous, it is becoming harder to understand how AI systems make decisions. This lack of transparency can raise ethical, legal, and social concerns about the use of AI.

Additionally, it is difficult to hold AI systems accountable for their actions if their decision-making process is not transparent. This lack of accountability can lead to unintended consequences, bias, and potential harm to individuals or society.

Therefore, it is essential to ensure that AI systems are transparent and accountable, and this can be achieved through Explainable AI (XAI) techniques. XAI provides understandable and justifiable explanations for AI decisions, enabling humans to better understand and trust AI systems. This can enhance the ethical and responsible development and deployment of AI systems and foster public trust in AI technology.

3. Objective of Explainable AI

The Explainable AI aims to create machine learning techniques that:

Produce more explainable models, while maintaining a high level of learning performance.
Enable human users to understand, appropriately trust, and effectively manage the emerging generation of artificially intelligent partners.

New machine-learning systems will have the ability to explain their rationale, characterize their strengths and weaknesses, and convey an understanding of how they will behave in the future.

4. Techniques Used in Explainable AI?

Explainable AI (XAI) uses various techniques to provide understandable and justifiable explanations for AI decisions. Some of the commonly used techniques include:

Rule-based systems: This technique uses a set of explicit rules to determine the output of an AI model.
Decision trees: Decision trees use a hierarchical structure of rules and conditions to make decisions, which can help in providing interpretable explanations for AI decisions.
Neural network visualization: This technique uses visual representations of the decision-making process to provide a better understanding of the relationship between inputs and outputs of an AI model.
Prototypes and counterfactuals: This technique generates examples that are similar or different from the original input to explain the decision of an AI model.
Local interpretable model-agnostic explanations (LIME): LIME uses a simple model to explain the predictions of a complex AI model by generating local explanations around a specific input.

These techniques are not exhaustive, and researchers continue to develop new methods to improve XAI. By using these techniques, XAI can help improve the transparency and accountability of AI systems and enhance human trust in AI technology.

5. How explainable AI works with above techniques?

Explainable AI (XAI) works with the help of various techniques to provide understandable and justifiable explanations for AI decisions.

Rule-based systems use explicit rules to determine the output of an AI model, and these rules can be interpreted by humans to understand the reasoning behind an AI decision.

Decision trees use a hierarchical structure of rules and conditions to make decisions, which can help in providing interpretable explanations for AI decisions. This can make it easier for humans to understand the decision-making process of an AI model.

Neural network visualization techniques use visual representations of the decision-making process to provide a better understanding of the relationship between inputs and outputs of an AI model. This can help humans to understand how the model arrived at a particular decision.

Prototypes and counterfactuals generate examples that are similar or different from the original input to explain the decision of an AI model. This can help humans to understand the model’s behavior in different scenarios.

Local interpretable model-agnostic explanations (LIME) use a simple model to explain the predictions of a complex AI model by generating local explanations around a specific input. This can help humans to understand the decision-making process of a complex AI model in a simplified manner.

By using these techniques, XAI can improve the transparency and accountability of AI systems, enabling humans to better understand and trust AI technology.
