Explainable AI (XAI): Working, Techniques & Benefits!

What is Explainable AI or XAI?

IBM defines explainable AI as “a set of processes and methods that allows human users to comprehend and trust the results and output created by machine learning algorithms.”

Explainable artificial intelligence (XAI) is the capacity of AI systems to explain their decisions that the human mind can interpret and understand. It plays a crucial role in the FAT principles, which focus on – 

• Fairness, 
• Accountability, and 
• Transparency. 

Simply put, AI often functions as a ‘Black Box’, which means it takes input and provides output without referring to its internal working mechanism. But suppose you want to know how AI came to that decision – that’s when XAI comes in. It doesn’t just give you an answer but also explains why it gave you that answer. 

Ultimately, this helps people to learn and better understand AI’s decisions before making any important decisions like loan approvals or medical diagnoses. 

Why Does Explainable AI Matter?

Explainable AI matters because it provides a medium for understanding why AI makes certain decisions. It helps humans interpret and understand machine learning (ML) algorithms, neural networks, and deep learning. 

Understanding AI decisions' reasoning helps build transparency and trust, especially in high-stakes applications like healthcare, finance, and criminal justice. 

It also assists organizations in making the right decisions without any potential errors or mistakes. So, explainable AI helps organizations feel more comfortable relying on it and makes it safer and more reliable in our lives.

Explainable AI also helps promote end-user trust, model audibility, and productive use of AI. It also mitigates compliance, legal, security, and reputational risks of production AI.

How Does Explainable AI Work?

Explainable Artificial Intelligence (XAI) uses various techniques to create machine learning models, with an emphasis on comprehensibility. 

These strategies assist users in understanding how AI makes decisions, uncover factors that influence it, and enhance machine learning models. They include data visualization, algorithms for AI explanation, and interpretation tools. 

XAI is founded on several principles and methods, including:

1. Transparency: This approach focuses on giving users access to the AI model so they can understand how the algorithm arrived at certain judgments. This clarity is achieved through the use of natural language processing or visualization tools.

2. Interpretability: Interpretability guarantees that the information supplied by the model has meaning for users. To get satisfactory results, explanation approaches that convert data into an approachable manner must be used. 

3. Controllability: Controllability allows users to go in and change the AI model. User control is increased by interaction techniques, which let users change the parameters of the model and affect its decisions.

4. Validity: Validity ensures the AI model produces reliable and accurate results. Testing the model on large datasets and training it on high-quality data are crucial to ensure its validity and accuracy.

What are the Benefits of Explainable AI (XAI)?

Here we’ve listed the top benefits of Explainable AI (XAI). Let’s discuss:

1. Improved Decision-making:

By understanding the reasoning underlying AI decisions, people may use XAI to make more certain and informed decisions.

2. Accelerated AI Optimization:

By understanding how AI models make decisions, organizations may more quickly pinpoint areas for development and effectively optimize their AI systems.

3. Boost Trust and Transparency:

XAI increases user confidence in the technology and its outcomes by fostering trust and offering transparent explanations for AI judgments. 

4. Increase Adoption of AI systems:

The technology is made more accessible and usable by transparent reasons for AI decisions, which encourages a greater range of industries and applications for its implementation.

5. Ensure Regulatory Compliance:

XAI helps businesses comply with regulations by reducing the ethical and legal concerns associated with opaque AI systems and providing auditable explanations for AI decisions.

Best Practices for Implementing Explainable AI (XAI)

Following, we’ve listed top practices that you must adopt for implementing Explainable AI (XAI). Let’s learn:

1. Understand your Audience:

Consider the XAI system users and the degree of clarification they require. Adjust the explanations to their level of experience and understanding. 

2. Cross-Functional AI Governance Committee:

Establish a diverse AI governance group of leaders from the legal, risk, and business domains in addition to technical specialists. This committee will choose the right technology to direct your AI development teams and establish the XAI organizational structure. The committee will also create guidelines that are specific to certain use cases and related risk categories. 

3. Choose Right Techniques:

Select the most suitable XAI techniques for the specific problem and use case you've identified, such as feature importance analysis, model-agnostic methods, or model-specific approaches.

4. Define Use Case and Decision Context:

Explain thoroughly your use case, the problem, and the setting for making decisions where your XAI will be applied. This clarity ensures that each model's distinct risks and associated legal obligations are fully recognized. 

5. Implement the Right XAI Tools:

Invest in hiring skilled professionals and acquiring the necessary tools to enable your business to leverage XAI. To stay current in this ever-changing industry, use custom, off-the-shelf, or open-source technology based on your present and future needs.

6. Evaluating XAI:

Use metrics such as accuracy, transparency, and consistency to assess your XAI models' efficacy and guarantee reliable explanations. 

7. Regular Testing:

XAI models undergo regular testing to ensure their objectivity and are devoid of bias. It's also beneficial to acknowledge and address any prejudices or limitations in the explanations provided. 

8. Monitoring & Updating:

Continuously monitoring and updating your XAI models helps maintain their fairness, accuracy, and transparency in AI decision-making processes, promoting trust and mitigating potential harm.

Different Key Explainable XAI Techniques

Below are key XAI techniques used to generate accurate and understandable explanations:

1. Feature Importance:

Identifies crucial input features influencing an AI decision, highlighting their significance.

2. Model-Agnostic Methods:

Provides explanations that are not exclusive to any one AI paradigm, but rather applicable to any black-box model. Two examples are Saliency maps and LIME (Local Interpretable Model-agnostic Explanations).

3. Model-Specific Methods:

Provide explanations specific to a certain AI paradigm, including rule-based and decision-tree models.

4. Counterfactual Explanations:

Demonstrates the changes that must be made to the input data to produce a different result, offering insights into AI judgments.

5. Visualization:

Uses graphical tools, including heatmaps, graphs, and interactive interfaces, to give clear and intuitive explanations of AI decisions.

What are the Challenges Involved in Explainable XAI?

Creating explanations that are both accurate and easy to understand with XAI involves several challenges:

1. Complexity:

XAI models can be difficult to understand and sophisticated, even for experts in data science and machine learning. 

2. Verification:

Confirming the precision and thoroughness of XAI explanations is challenging. While the initial results may be straightforward, tracking the audit trail becomes more difficult as the AI engine repeats and iterates over data. 

3. Computational Intensity:

The computational demands of XAI techniques may cause scalability issues with large datasets and real-world applications.

4. Generalization:

XAI can have difficulty offering explanations that work well in a variety of settings and circumstances.
