Clarifying Model Transparency: Interpretability versus Explainability in Deep Learning with MNIST and IMDB Examples
The impressive capabilities of deep learning models are often counterbalanced by their inherent opacity, commonly termed the "black box" problem, which impedes their widespread acceptance in high-trust domains. In response, the intersecting disciplines of interpretability and explainability, collectively falling under the Explainable AI (XAI) umbrella, have become focal points of research. Although these terms are frequently used as synonyms, they carry distinct conceptual weights. This document offers a comparative exploration of interpretability and explainability within the deep learning paradigm, carefully outlining their respective definitions, objectives, prevalent methodologies, and inherent difficulties. Through illustrative examinations of the MNIST digit classification task and IMDB sentiment analysis, we substantiate a key argument: interpretability generally pertains to a model's inherent capacity for human comprehension of its operational mechanisms (global understanding), whereas explainability is more commonly associated with post-hoc techniques designed to illuminate the basis for a model's individual predictions or behaviors (local explanations). For example, feature attribution methods can reveal why a specific MNIST image is recognized as a '7', and word-level importance can clarify an IMDB sentiment outcome. However, these local insights do not render the complex underlying model globally transparent. A clear grasp of this differentiation, as demonstrated by these standard datasets, is vital for fostering dependable and sound artificial intelligence.

Investigating the Duality of Interpretability and Explainability in Machine Learning
Garouani, Moncef, Mothe, Josiane, Barhrhouj, Ayah, Aligon, Julien
--The rapid evolution of machine learning (ML) has led to the widespread adoption of complex "black box" models, such as deep neural networks and ensemble methods. However, their inherently opaque nature raises concerns about transparency and interpretability, making them untrustworthy decision support systems. T o alleviate such a barrier to high-stakes adoption, research community focus has been on developing methods to explain black box models as a means to address the challenges they pose. Efforts are focused on explaining these models instead of developing ones that are inherently interpretable. Designing inherently interpretable models from the outset, however, can pave the path towards responsible and beneficial applications in the field of ML. In this position paper, we clarify the chasm between explaining black boxes and adopting inherently interpretable models. We emphasize the imperative need for model interpretability and, following the purpose of attaining better (i.e., more effective or efficient w.r .t. predictive performance) and trustworthy predictors, provide an experimental evaluation of latest hybrid learning methods that integrates symbolic knowledge into neural network predictors. We demonstrate how interpretable hybrid models could potentially supplant black box ones in different domains. In the rapidly evolving field of artificial intelligence, machine learning techniques (e.g., Artificial Neural Networks) are among the most widespread tools for high stakes decision-making across diverse domains within society [1]. The learning process consists of the model internal hyperparameters tuning in order to mine the useful information buried in the domain data and to maximize the predictive capability [2].

Leaf diseases detection using deep learning methods
This study, our main topic is to devlop a new deep-learning approachs for plant leaf disease identification and detection using leaf image datasets. We also discussed the challenges facing current methods of leaf disease detection and how deep learning may be used to overcome these challenges and enhance the accuracy of disease detection. Therefore, we have proposed a novel method for the detection of various leaf diseases in crops, along with the identification and description of an efficient network architecture that encompasses hyperparameters and optimization methods. The effectiveness of different architectures was compared and evaluated to see the best architecture configuration and to create an effective model that can quickly detect leaf disease. In addition to the work done on pre-trained models, we proposed a new model based on CNN, which provides an efficient method for identifying and detecting plant leaf disease. Furthermore, we evaluated the efficacy of our model and compared the results to those of some pre-trained state-of-the-art architectures.

Seeking Interpretability and Explainability in Binary Activated Neural Networks
Leblanc, Benjamin, Germain, Pascal
We study the use of binary activated neural networks as interpretable and explainable predictors in the context of regression tasks on tabular data; more specifically, we provide guarantees on their expressiveness, present an approach based on the efficient computation of SHAP values for quantifying the relative importance of the features, hidden neurons and even weights. As the model's simplicity is instrumental in achieving interpretability, we propose a greedy algorithm for building compact binary activated networks. This approach doesn't need to fix an architecture for the network in advance: it is built one layer at a time, one neuron at a time, leading to predictors that aren't needlessly complex for a given task.

Machine Learning Interpretability and Explainability
Machine Learning (ML) interpretability and explainability are important concepts that refer to the ability of humans to understand and interpret the decisions made by machine learning models. These concepts have become increasingly important as machine learning models are being used in more critical applications, such as healthcare, finance, and criminal justice, where the decisions made by these models can have a significant impact on people's lives. One of the main challenges of ML interpretability and explainability is the complexity of the models. Machine learning models can be very complex, with many layers of neurons and thousands or even millions of parameters. This complexity can make it difficult for humans to understand how the model is making its decisions, which can be a problem when trying to explain the results to non-technical users.

Interpretability and explainability can lead to more reliable ML
With machine learning on the rise, businesses are relying on machine learning models and algorithms to derive insights from data and make predictions. Serg Masís, data scientist and author of Interpretable Machine Learning with Python from Packt Publishing Ltd., believes that in order to know how and why those algorithms make predictions, they must be both interpretable and explainable. In this Q&A, Masís discusses these concepts, coined "interpretablility" and "explainability," and how they are more than just buzzwords or theory by explaining their value in real-world scenarios. Editor's note: The following interview was edited for length and clarity. What near-future trends in machine learning will emerge, and will they adhere to the advice in this book about interpretability and explainability?
Natural Language Processing First Steps: How Algorithms Understand Text
This article will discuss how to prepare text through vectorization, hashing, tokenization, and other techniques, to be compatible with machine learning (ML) and other numerical algorithms. I'll explain and demonstrate the process. Natural Language Processing (NLP) applies Machine Learning (ML) and other techniques to language. However, machine learning and other techniques typically work on the numerical arrays called vectors representing each instance (sometimes called an observation, entity, instance, or row) in the data set. We call the collection of all these arrays a matrix; each row in the matrix represents an instance.
Hand Labeling Considered Harmful
We are traveling through the era of Software 2.0, in which the key components of modern software are increasingly determined by the parameters of machine learning models, rather than hard-coded in the language of for loops and if-else statements. There are serious challenges with such software and models, including the data they're trained on, how they're developed, how they're deployed, and their impact on stakeholders. These challenges commonly result in both algorithmic bias and lack of model interpretability and explainability. There's another critical issue, which is in some ways upstream to the challenges of bias and explainability: while we seem to be living in the future with the creation of machine learning and deep learning models, we are still living in the Dark Ages with respect to the curation and labeling of our training data: the vast majority of labeling is still done by hand.
