Deep Latent Representation Learning for Pan-Cancer Classification with Explainable Boosting from High-Dimensional Gene Expression Data Diptadip Maiti, Madhuchhanda Basak Esic 2026 Proceedings 6th International Conference on Emerging Systems and Intelligent Computing, 2026 High-dimensional gene expression data pose substantial challenges for predictive modeling due to noise, redundancy, and the curse of dimensionality. This work introduces a hybrid machine learning framework that integrates a Variational Autoencoder (VAE) for nonlinear dimensionality reduction with an Explainable Boosting Machine (EBM) for transparent multiclass cancer classification. The VAE compresses over 20,000 transcriptomic features into a 64-dimensional latent space while preserving biologically meaningful structure, yielding improved separability across tumor types. These latent representations are then classified using an EBM, enabling inherently interpretable predictions supported by global feature importance and SHAPbased local explanations. Experiments on the TCGA Pan-Cancer dataset demonstrate the effectiveness of the proposed pipeline, achieving 0.98 accuracy, 0.99 macro-precision, 0.97 macro-recall, and 0.98 macro-F1, with per-class F1-scores ranging from 0.95 to 1.00. The results highlight that the VAE-EBM framework provides both high predictive performance and clinical interpretability, offering a promising direction for precision oncology.
Impact of Bio-inspired Optimization Techniques on EEG Signal Classification for Psychiatric Disorder Diagnosis Madhuchhanda Basak, Diptadip Maiti International Conference on Computing Intelligence and Application Ciacon 2025, 2025 This study investigates the classification of psychiatric disorders using electroencephalogram (EEG) data, with a focus on enhancing feature selection and classification accuracy through advanced optimization techniques. The methodology comprises several stages: EEG signal acquisition, preprocessing, feature extraction, and clinical-based class labelling. Given the inherent challenges of high-dimensional data and class imbalance in EEG datasets, five bio-inspired optimization algorithms are employed to optimize feature selection: Artificial Bee Colony (ABC), Particle Swarm Optimization (PSO), Monarch Butterfly Optimization (MBO), Harris Hawks Optimization (HHO), and Glowworm Swarm Optimization (GSO). These algorithms aim to identify the most relevant features while minimizing computational overhead. An Artificial Neural Network (ANN) classifier is trained on the optimized feature sets to predict psychiatric disorders. A comparative analysis of the optimization methods reveals that HHO offers the fastest execution time, MBO excels in selecting a diverse set of features, and ABC provides a strong balance between efficiency and classification accuracy. The findings underscore the significance of selecting suitable optimization strategies tailored to computational resources and data characteristics to improve EEG-based psychiatric disorder classification.
Patch-wise Deep Learning with Attention and Hybrid Supervision for Fundus-Based Glaucoma Screening Diptadip Maiti, Madhuchhanda Basak Proceedings of the International Conference on Research in Computational Intelligence and Communication Networks Icrcicn, 2025 Glaucoma is a significant cause of permanent blindness. Accurate detection of fundus imagery is crucial for timely action. We present a unique patch-driven deep learning model that includes EfficientNet-B0 backbones, an attentionbased ensemble mechanism, and hybrid loss functions. The model processes eight image patches in parallel and leverages intermodel consistency via KL divergence, label smoothing, and cosine similarity to improve robustness. We detail the methodology, mathematical formulations, and implementation, and validate the model on the ACRIMA dataset, achieving significant improvements over baseline methods.
NeuroExplain: An Explainable Deep Learning Framework for Multiclass Emotion Recognition from Gameplay EEG Diptadip Maiti, Madhuchhanda Basak, Sudipta Hazra 2025 5th International Conference on Emerging Research in Electronics Computer Science and Technology Icerect 2025, 2025 This paper presents a novel framework for emotion detection from electroencephalogram (EEG) signals, integrating both deep learning and traditional machine learning approaches to enhance classification accuracy and model interpretability. The proposed pipeline includes preprocessing, feature extraction, class balancing using SMOTE, and the evaluation of multiple classifiers, including XGBoost, Random Forest, Support Vector Machine (SVM), and a deep Artificial Neural Network (ANN). Among these, XGBoost achieved the highest accuracy of 94.98%, followed by Random Forest (93.49%) and ANN (93.00%). The performance of these models was evaluated using metrics such as accuracy, F1-score, and confusion matrix. Additionally, the interpretability of the top-performing models was further enhanced using explainable AI techniques, such as SHAP and Integrated Gradients (IG), which provided valuable insights into the key EEG features contributing to emotion classification. The results demonstrate the effectiveness of ensemble-based methods and deep learning for EEG-based emotion detection, while highlighting the importance of model transparency in real-world applications. The framework holds significant potential for improving emotion detection systems and offers avenues for future research, including the exploration of advanced feature extraction methods, real-time classification, and further optimization of explainability techniques.
Region based Image Contrast Enhancement Depending on Local Dominant Colour Component Debashis Das, Diptadip Maiti Proceedings 2024 8th International Conference on Imaging Signal Processing and Communications Icispc 2024, 2024 In this paper, we propose an image contrast enhancement mechanism by analysing the dominant colour component of every contributory pixel. The contrast enhancement is performed on the regions having similar dominating colour components by employing local histogram equalization. The process ensures the increment of the colour purity by preserving the level of brightness which is a major drawback of histogram equalization-based methods. The proposed method provides satisfactory results without any learning mechanism applied in the system which reduces the execution time of the process as well. The proposed algorithm is formulated, experimented and tested on a large set of standard colour images, in RGB format, collected from various databases. We compare the proposed method with both standalone and learning based image enhancement algorithms from the literature. The comparative analysis establishes the efficacy of the proposed method.
