AI decision-making refers to the process of utilizing AI algorithms and technologies to make complex decisions. With advancements in machine learning and deep learning techniques, AI-driven decision-making has become increasingly prevalent in various sectors, including healthcare, finance, and transportation. The growing reliance on AI is primarily driven by its potential to enhance efficiency, accuracy, and speed in decision-making processes, leading to improved outcomes and cost-effectiveness.

However, the question is: Can we trust the result blindly? We should always evaluate the results and consider potential biases and limitations, especially when making important decisions. Explainable AI (XAI) is the solution to this concern. XAI refers to a collection of techniques that improve the ability of human users to interpret and trust the output and findings of machine learning systems. This blog will explain the problem we are facing, the benefits and challenges of XAI, as well as the future of XAI.

Challenges in AI Decision-Making

Along with its benefits, there are potential risks and challenges associated with AI decision-making. One major concern is the lack of transparency and interpretability in AI algorithms, making it difficult to understand how and why certain decisions are made. This can raise issues of accountability and fairness, especially in sensitive areas like healthcare where wrong decisions can have serious consequences. Additionally, the reliance on AI decision-making can lead to a loss of human judgment and intuition, which are crucial in certain complex scenarios that require ethical considerations. Lastly, there is the risk of data bias, as AI systems are trained on historical data that may perpetuate existing biases and inequalities. These challenges highlight the importance of addressing ethical, legal, and privacy concerns in AI decision-making to ensure its responsible implementation and minimize potential harm.

Explainable AI vs. "Regular" AI

Explainable AI stands in contrast to traditional black-box AI models, which operate by making decisions based on complex algorithms that are difficult to interpret or explain. Unlike black-box models, explainable AI provides a clear and understandable rationale for its decisions, allowing users to trace the logic and understand the factors that influenced the outcome. This transparency enables users to identify potential biases, errors, or unethical behaviour in the AI system, which is not possible with black-box models. By bridging this gap, explainable AI promotes accountability, trust, and responsible usage of AI technologies.

Benefits of Explainable AI

Understand the Decision-Making Process and Build Trust

Explainable AI can provide insights into the decision-making process of AI models by offering explanations and justifications for the outcomes or recommendations they produce. Knowing the reasoning behind AI's outcomes, users could potentially adjust or modify the inputs and algorithms to reach desired results. The way AI thinks might potentially serve as a source of creative motivation for humans.

Additionally, the transparency allows users to understand the reasoning behind AI's decisions and builds trust in the system. By providing clear explanations, stakeholders can have a better understanding of how AI models work, which in turn encourages confidence in their capabilities. This increased trust and understanding fosters a more collaborative relationship between humans and AI, leading to greater acceptance and integration of AI technology into critical systems and decision-making processes.

For example, imagine a scenario where AI is used in the healthcare industry to predict patient outcomes and recommend treatment plans. The system can analyze data from thousands of patients with similar conditions and provide explanations for why certain treatments are recommended. This transparency allows healthcare professionals to make more informed decisions, potentially leading to better patient outcomes. Patients and their families can also have more trust in the AI system when they understand the reasoning behind the recommendations, resulting in greater acceptance and collaboration between humans and AI in healthcare decision-making processes.

Identify Biases and Discriminatory Patterns

Explainable AI can play a crucial role in identifying biases and discriminatory patterns in decision-making processes. By providing transparent explanations for its decisions, AI systems can be audited and evaluated for any unjust or biased outcomes. This can help uncover hidden biases within the data or algorithms used, enabling stakeholders to mitigate and address these issues. The ability to identify and rectify biases ultimately leads to fairer and more equitable outcomes, promoting social justice and inclusivity in AI-driven decision-making.

For example, in the hiring process, an AI system can be used to evaluate job applicants based on their resumes and qualifications. However, without explainable AI, it may be difficult to determine if the system is inadvertently favouring certain demographics or perpetuating discriminatory practices. By using explainable AI, stakeholders can examine the decision-making process and identify any biases that may exist. This can lead to improvements in the system and ensure that all applicants are given equal opportunities regardless of their background or characteristics.

Minimize Risks

Explainable AI could also mitigate compliance, legal, security, and reputational risks. Explainable AI provides transparency and accountability in the decision-making process, which is crucial in industries where compliance with regulations and laws is paramount. It allows organizations to easily identify and rectify any discriminatory practices, ensuring they are in full compliance with equal opportunity regulations. Additionally, by being able to explain the reasoning behind AI-driven decisions, organizations can build trust with their customers, stakeholders, and regulatory bodies, reducing the risk of legal and reputational backlash. Lastly, explainable AI can also enhance the security of AI systems by enabling thorough audits and vulnerability assessments, safeguarding against potential biases and malicious attacks.

Examples of Explainable Techniques

SHapley Additive exPlanations (SHAP) is one explainable technique that can be used to provide insights into the decision-making process of AI models. Developed based on cooperative game theory concepts by Lloyd Shapley and Shapley values, SHAP values offer a consistent and mathematically sound approach to distribute the contribution of each feature fairly among all possible combinations. By analyzing the contribution of each feature to the final prediction, SHAP helps users understand how the model arrived at its decision.

Local Interpretable Model-Agnostic Explanations (LIME) is another popular technique used in explainable AI. LIME focuses on providing explanations for individual predictions made by AI models. It achieves this by creating a local interpretable model around the prediction and highlighting the most influential features. This allows users to understand the reasoning behind specific predictions and gain insights into the decision-making process on a more granular level.

Machine learning teams in industry often use both SHAP and LIME, with LIME for a better explanation of a single prediction and SHAP for understanding the entire model and feature dependencies. LIME is faster in terms of computational time and can be useful with tabular, text, and image data. SHAP can take more time, but it can compute values for global model interpretations. There are other explainable methods, such as counterfactual explanations and rule-based methods, that can also contribute to a more thorough understanding of AI decision-making. Counterfactual explanations generate alternative scenarios to explain why a certain decision was made, while rule-based methods provide interpretable rules that govern the decision-making process. These additional methods offer different perspectives and can be useful in different scenarios, depending on the specific requirements and goals of the user. Overall, the combination of SHAP, LIME, and other explainable methods can provide a robust toolkit for understanding and improving AI decision-making.


One challenge in implementing explainable AI is the complexity and black-box nature of some machine learning models, such as deep neural networks, which makes it difficult to understand their decision-making process. Sometimes, even the AI architects don’t know how the algorithm comes up with the results. This makes it hard to check for accuracy and leads to a loss of control, accountability, and auditability. This can be addressed by using techniques like SHAP and LIME, which provide insights into the importance of different features and how they contribute to the final decision.

Another challenge is the trade-off between interpretability and performance, as some explainable methods may sacrifice accuracy in order to provide interpretable explanations. This can be mitigated by developing hybrid models that combine the strengths of both interpretable and complex models, striking a balance between transparency and performance.

Additionally, ensuring the ethical use of AI and addressing bias in decision-making are important challenges that need to be addressed in the development and deployment of explainable AI. To ensure ethical use, it is crucial to have clear guidelines and regulations in place to prevent the misuse of AI systems. Furthermore, addressing bias requires careful examination of the data used to train the AI models. Actions need to be taken to mitigate any biases that may be present. By tackling these challenges, we can unlock the full potential of explainable AI.

In the future, explainable AI is likely to focus on improving techniques for making AI decisions easier to understand and building stronger frameworks for doing this. Researchers are working on methods to enhance the transparency of complex AI models, making it easier for humans to understand how and why these models arrive at certain conclusions. Additionally, efforts are being made to create standardized evaluation metrics and benchmarks for measuring the explainability of AI systems. As the field progresses, explainable AI is expected to become an integral part of various domains, enabling users to trust and confidently rely on AI-driven decisions.
