Interpretable machine learning (IML) has emerged as a crucial field in bridging the gap between traditional black-box models and human understanding. In this survey paper, we present an overview of various techniques and methodologies developed to enhance the interpretability of machine learning models. We categorize these techniques based on their approaches, including model-specific methods, model-agnostic methods, and post-hoc interpretation techniques. Furthermore, we discuss the importance of interpretability in real-world applications, challenges, and future directions in the field of interpretable machine learning. Through this exploration, it will shed light on the importance of and the critical role of interpretability in advancing AI technologies and emphasizes the need for ongoing research and collaboration in this dynamic field to inspire further research and development in this rapidly evolving field.
