Recognizing text extracted from multiple domains is complex and challenging because complexities vary from one domain to another. Most existing methods focus either on natural scene text or specific text type but not text of multiple domains, namely, scene, underwater, and drone texts. In addition, the state-of-the-art models ignore the vital cues that exist in multiple instances of the text. This paper presents a new method called the Student-Teacher-Assistant (STA) network, which involves dual CLIP models to exploit cues in multiple text instances. The model that uses ResNet50 in its image encoder is called helper CLIP, while the model that uses ViT in its image encoder is called primary CLIP. The proposed work processes both models simultaneously to extract visual and textual features through image and text encoders. Our work uses cosine similarity for the randomly chosen input image to detect instances similar to the input image. The input and similar instances are supplied to primary and helper CLIPs for visual and textual feature extraction. The outputs of dual CLIPs are fused in a different way through the alignment step for recognizing text accurately, irrespective of domains. To demonstrate the proposed model’s significance, experiments are conducted on a set of standard natural scene text datasets (regular and irregular), underwater images, and drone images. The results on three different domains show that the proposed model outperforms the state-of-the-art recognition models. The datasets and code for public use in training and testing shall be made available on GitHub. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Early diagnosis of retinal diseases is crucial for preventing blindness. However, due to background variations and degradation in the images, retinal vessel segmentation has become challenging. As a result, accurate segmentation of the retinal vessels is essential for enhancing diagnosis to identify the disease. To achieve this, inspired by the special ability of the attention mechanism, which detects vital regions, and UNet, which segments the vital region, we propose a combination of a new attention mechanism and modified UNet for segmenting vessels in retina images. In the proposed segmentation model, the convolutional blocks have been modified to capture multiscale spatial information by varying the convolution dilation rates. Similarly, the Trainable tanh activation (T-Tanh) is adapted in a new way to identify changes in the flow of the feature gradients to differentiate between the retinal vessel pixels and the background. Furthermore, to make the segmentation robust, the Gated Edge Attention (GEA) network is proposed. The effectiveness of the segmentation is demonstrated by testing on two benchmark datasets, namely, STARE and CHASE. The results show that the performance of the proposed method is superior to the state-of-the-art methods. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

In this work, we present a model for document-grounded response generation in dialog that is decomposed into two components according to Bayes' theorem. One component is a traditional ungrounded response generation model and the other component models the reconstruction of the grounding document based on the dialog context and generated response. We propose different approximate decoding schemes and evaluate our approach on multiple open-domain and task-oriented document-grounded dialog datasets. Our experiments show that the model is more factual in terms of automatic factuality metrics than the baseline model. Furthermore, we outline how introducing scaling factors between the components allows for controlling the tradeoff between factuality and fluency in the model output. Finally, we compare our approach to a recently proposed method to control factuality in grounded dialog, CTRL (Rashkin et al., 2021), and show that both approaches can be combined to achieve additional improvements. © 2022 Association for Computational Linguistics.

Accurate identification and segmentation of cancer cell nuclei from histopathological images is of vital importance in efficient cancer diagnosis and treatment. Problems in manual segmentation raised the need for automated lymphocyte detection as manual techniques are time-consuming, error-prone, and are more subjected to pathologists conflict. Much work have been done previously in automated detection of lymphocyte. In this study, we propose a unique architecture called CB-UNet for nuclei segmentation in cancer histopathology images. Our approach, CB-UNet utilizes the concept of “channel boosting,” employing multiple encoders to enhance the input channels and generate diverse and informative feature maps. By merging these feature maps and passing them through a decoder layer, we generate high-resolution segmentation masks. We evaluated our model's performance using evaluation metrics such as Intersection over Union (IOU) and Dice coefficient on the Lysto dataset and the MonuSeg dataset. These metrics demonstrate the superiority of our proposed architecture, CB-UNet, over existing methods. The results highlight the enhanced precision and effectiveness of nuclei segmentation for cancer diagnosis and treatment. This study signifies an advancement in nuclei segmentation techniques, with the potential to improve the overall treatment of cancer patients.

Cross-domain image style transfer task is an attractive topic for several applications, such as image-to-image style transfer, text-to-image style transfer, artistic image generation, etc. In cross-domain image style transfer tasks (e.g., image-to-image style transfer, artistic image-to-image style transfer, text-to-image style transfer, etc.), training becomes cumbersome due to differences in data distribution across domains and complex model architectures. Unlike existing domain adaptation and domain-independent methods that focus on robust and sufficient feature extraction, this work focuses on disentangling the latent space through latent optimization. For this purpose here we propose a new idea of styled image generation from the latent space of StyleGAN which works well for image-to-image and text-to-image style transfer. We critically analyzed the low-dimensional latent structure and its effect on cross-domain image style transfer tasks and finally proposed a method along with a latent optimizing procedure to overcome the problem of style transfer. The experimental results on different standard datasets show that the proposed model is robust, effective, and generic compared to the state-of-the-art models. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Processing non-stationary data streams has gained a significant research interest in the recent years. Most of the current state-of-the-art approaches in the literature exhibit hybrid solutions based on an ensemble learning paradigm, extending its parallel architecture with a drift detector. Such integrated mechanism of concept drift detection often relies on the metadescription of incoming data. The article presents a proposition of a novel hybrid classifier – the Metafeature Concept Selector. The method employs the analysis of statistical metafeatures calculated on subsequent data batches to identify the currently processed concept. The work is concluded with an extensive experimental analysis of synthetic data streams with recurrent concepts, various dimensionality and various concept change frequencies, showing that the proposed approach brings improvement when integrated with state-of-the-art base incremental learners.
