An IoT-driven machine learning system for real-time smart crop recommendation and optimization in precision agriculture Nitish Rupesh Sawant, Anuj Kumar, Sangeeta Pant, Ketan Kotecha Discover Artificial Intelligence, 2026 Agriculture is essential to global food security and sustainable development. The use of machine learning (ML) and Internet of Things (IoT) has the potential to enhance crop production and improve resource management through enhanced precision agriculture. This article describes a smart crop recommender system developed to support both ML-based decision making and real-time environmental sensing. At the core of the system is a capacitive soil moisture sensor and a temperature-humidity sensor interfaced using an Arduino Nano. Using a nRF24L01 transceiver employing the 2.4 GHz Enhanced Shock Burst (ESB) protocol, the sensor information can be wirelessly transmitted. Data collected from the sensors are sent to an ESP32 module that posts the information to the Blynk web application through Wi-Fi, allowing real-time remote access. As the data source for the crop recommender model, the Blynk application provides the data needed to perform data analysis on the various ML algorithms (Random Forest, Bagging, Decision Tree, Gradient Boosting, and Enhanced Gaussian Naive Bayes [EGNB]) to determine the most suitable type of crop based on the current soil and environmental conditions. Based on the analysis, the EGNB model showed superiority with an accuracy of 99.55% with respect to precision, recall, and F1-score. This system provides an economically viable and expandable approach to smart agricultural practices, which integrates cutting-edge machine-learning modelling with digital tools for obtaining data in real-time (IoT). These capabilities allow users to receive and utilize actionable, data-driven guidance in real time when making decisions about crop production.
Hesitant bi-fuzzy multi-attribute information fusion with expert reliability Shshank Chaube, Anuj Kumar, Manoj Kumar Singh, Chandan Singh Ujarari, Sawan Kumar Rawat Scientific Reports, 2025 Selecting alternatives wisely is essential in any multi-attribute decision-making (MADM) process, and it requires the participation of multiple experts. Initial decision data and the contributing experts' reliability affect the preciseness of the decision outcomes. However, no expert possesses exhaustive knowledge, and their estimations may exhibit varying preferences. Many times, experts hesitate to give contradictory/ conflicting information. Hence, the information gathered from them includes the hesitancy of the expert and conflict. To account for expert influence while preserving the integrity of the original data during aggregation, this paper proposes a hesitant bi-fuzzy information fusion (HBFIF) method that integrates expert reliability (ER) into the decision-making framework in the conflicting framework. Initially, the impression of expert reliability in the decision-making process is examined, and a reliability metric is constructed based on the degree of similarity among expert opinions. The power average (PA) operator is then used with expert reliability to aggregate expert preferences while preserving as much of the original data as feasible. Subsequently, inspired by the TOPSIS method, the hesitant bi-fuzzy information fusion approach is developed to maintain experts' original opinions and risk preferences depending on their assessed reliability. Finally, the proposed HBFIF method is applied to the multi-attribute decision-making framework in selecting an efficient hydrogen storage method in automobiles to confirm its effectiveness and applicability, underscoring its practical relevance and implementation.
Repairing the inconsistent pairwise comparison matrix using a cosine distance and grey wolf optimiser-based framework in multi-criteria decision-making Shalu Kaushik, Sangeeta Pant, Lokesh Kumar Joshi, Anuj Kumar, Ketan Kotecha, Ambarish Kulkarni Scientific Reports, 2025 Verifying the consistency of the Pairwise Comparison Matrix (PCM) is essential in the Multi-Criteria Decision-Making (MCDM) process, as decision-makers cannot use an inconsistent PCM as a credible reference. To optimize a PCM that is inconsistent, the primary requirement is to minimize the difference between the original and substitute matrices while improving the Consistency Ratio (CR) of the original Matrix. In this article, we employ a novel framework that uses a novel distance formula focused on the Cosine Distance metric to address inconsistencies in the PCM. Additionally, we utilize a swarm intelligence-based Grey Wolf Optimizer (GWO) to address further and repair these inconsistencies in the PCM. GWO leverages the exploration and exploitation strategies of grey wolves to identify the best-optimized value that satisfies the CR threshold while aligning closely with the decision-makers' (DM) original judgments. Additionally, we have introduced the maximum correction range ε. This ε is very helpful in achieving consistency based on the preference level of the DM, to what extent the DM wants to change the correction range. The experimental results indicate that we achieve better outcomes for the special case matrix with a CR of 0.546487; we obtain the resultant Matrix with a CR of 0.073397 with a minimal correction range of E = 3 in the 94th iteration. Experimental results also demonstrate that the suggested novel framework successfully generates a consistent matrix with minimal deviation from the original Matrix and outperforms previously used algorithms, such as ANT-based Analytic Hierarchy Process (ANTAHP) and Particle Swarm Optimization (PSO).
Optimized deep learning for brain tumor detection: a hybrid approach with attention mechanisms and clinical explainability Aditya Jayesh Aiya, Nishant Wani, Mayur Ramani, Anuj Kumar, Sangeeta Pant, Ketan Kotecha, Ambarish Kulkarni, Abdullah Al-Danakh Scientific Reports, 2025 Brain tumor classification (BTC) from Magnetic Resonance Imaging (MRI) is a critical diagnosis task, which is highly important for treatment planning. In this study, we propose a hybrid deep learning (DL) model that integrates VGG16, an attention mechanism, and optimized hyperparameters to classify brain tumors into different categories as glioma, meningioma, pituitary tumor, and no tumor. The approach leverages state-of-the-art preprocessing techniques, transfer learning, and Gradient-weighted Class Activation Mapping (Grad-CAM) visualization on a dataset of 7023 MRI images to enhance both performance and interpretability. The proposed model achieves 99% test accuracy and impressive precision and recall figures and outperforms traditional approaches like Support Vector Machines (SVM) with Histogram of Oriented Gradients (HOG), Local Binary Pattern (LBP) and Principal Component Analysis (PCA) by a significant margin. Moreover, the model eliminates the need for manual labelling-a common challenge in this domain-by employing end-to-end learning, which allows the proposed model to derive meaningful features hence reducing human input. The integration of attention mechanisms further promote feature selection, in turn improving classification accuracy, while Grad-CAM visualizations show which regions of the image had the greatest impact on classification decisions, leading to increased transparency in clinical settings. Overall, the synergy of superior prediction, automatic feature extraction, and improved predictability confirms the model as an important application to neural networks approaches for brain tumor classification with valuable potential for enhancing medical imaging (MI) and clinical decision-making.
A Deep Reinforcement Learning Framework for Strategic Indian NIFTY 50 Index Trading Raj Gaurav Mishra, Dharmendra Sharma, Mahipal Gadhavi, Sangeeta Pant, Anuj Kumar AI Switzerland, 2025 This paper presents a comprehensive deep reinforcement learning (DRL) framework for developing strategic trading models tailored to the Indian NIFTY 50 index, leveraging the temporal and nonlinear nature of financial markets. Three advanced DRL architectures deep Q-network (DQN), double deep Q-network (DDQN), and dueling double deep Q-network (Dueling DDQN) were implemented and empirically evaluated. Using a decade-long dataset of 15-min interval OHLC data enriched with technical indicators such as the exponential moving average (EMA), pivot points, and multiple supertrend configurations, the models were trained using prioritized experience replay, epsilon-greedy exploration strategies, and softmax sampling mechanisms. A test set comprising one year of unseen data (May 2024–April 2025) was used to assess generalization performance across key financial metrics, including Sharpe ratio, profit factor, win rate, and trade frequency. Each architecture was analyzed in three progressively sophisticated variants incorporating enhancements in reward shaping, exploration–exploitation balancing, and penalty-based trade constraints. DDQN V3 achieved a Sharpe ratio of 0.7394, a 73.33% win rate, and a 16.58 profit factor across 15 trades, indicating strong volatility-adjusted suitability for real-world deployment. In contrast, the Dueling DDQN V3 achieved a high Sharpe ratio of 1.2278 and a 100% win rate but with only three trades, indicating an excessive conservatism. The DQN V1 model served as a strong baseline, outperforming passive strategies but exhibiting limitations due to Q-value overestimation. The novelty of this work lies in its systematic exploration of DRL variants integrated with enhanced exploration mechanisms and reward–penalty structures, rigorously applied to high-frequency trading on the NIFTY 50 index within an emerging market context. Our findings underscore the critical importance of architectural refinements, dynamic exploration strategies, and trade regularization in stabilizing learning and enhancing profitability in DRL-based intelligent trading systems.
COST AND RELIABILITY OPTIMIZATION OF A COMPLEX SYSTEM USING MULTI-OBJECTIVE GREY WOLF OPTIMIZATION TECHNIQUE Anuj Kumar, Negi, Ganga, Mangey Ram, Pant, Sangeeta, Dimri, Sushil Chandra Reliability Theory and Applications, 2025 Modern engineering systems increasingly focus on multi-objective optimization. Nature-inspired optimization techniques have shown superior efficiency and effectiveness compared to many traditional methods across various parameters. This work demonstrates the reliability and cost optimization of a complex bridge system using the Multi-Objective Grey Wolf Optimization algorithm (MOGWO). The bridge system in question is a seriesparallel system. A key performance highlight is the use of an archive for search agents to generate a Pareto optimal front (PoF) with a minimal number of iterations. Among the various solutions in the PoF, the solution set that best meets the multi-objective criteria is preferred. Additionally, statistical analyses are conducted to further validate the competitiveness of the results.
An Overview and Comparison of Axiomatization Structures Regarding Inconsistency Indices’ Properties in Pairwise Comparisons Methods: A Decade of Advancements Sangeeta Pant, Anuj Kumar, Jiří Mazurek International Journal of Mathematical Engineering and Management Sciences, 2025 Mathematical analysis of the analytic hierarchy process (AHP) led to the development of a mathematical function, usually called the inconsistency index, which has the center role in measuring the inconsistency of the judgements in AHP. Inconsistency index is a mathematical function which maps every pairwise comparison matrix (PCM) into a real number. An inconsistency index can be considered more trustworthy when it satisfies a set of suitable properties. Therefore, the research community has been trying to postulate a set of desirable rules (axioms, properties) for inconsistency indices. Subsequently, various axiomatic frameworks for these functions have been proposed independently. However, the existing literature remains fragmented and lacks a unifying framework. Therefore, the objective of this article is twofold. Over the past decade (2014-2024), significant progress has been made in the axiomatization of inconsistency indices' properties. In this article, we first provide a comprehensive review of these advancements. We then critically evaluate and compare the aforementioned axiomatic structures, discussing future research directions.
