A significant defect in our society is the social divide between people with disabilities and those without. Communication is one of the most significant characteristics of humans, who are thought of as social animals. One of the biggest challenges for those with hearing and vocal impairments is communication. For someone who has hearing and voice impairments, this incapacity to communicate causes regular issues and interferes with their everyday tasks. We have suggested a way to get beyond this communication obstacle in our research work. Everyone can use this solution with ease, and with a few tweaks, it can be made to function on the majority of systems having camera modules. Our method employs an integrated camera module to record hand movements in real time, based on landmarks or hand key points. Proposed LSTM based model have been evaluated in real time environment and a significant result have been reported as mentioned in the result section.

The rise in mobile internet usage especially using cellular networks demands efficient performance for web traffic, primarily made up of short TCP flows. For TCP, Cubic is the most widely deployed congestion control algorithm. mmWave and THz offer very high bandwidth and low latency, enabling faster speeds and reduced delay for companies deploying innovative applications, positioning them as the future of wireless technology. As such, we are compelled to thoroughly evaluate the performance of Cubic in various mmWave specific NLoS/LoS scenarios. In the process, we find Cubic really struggling when it comes to static NLoS scenarios and long connections particularly because Cubic keeps on attempting recovery from slow-start but fails due to the NLoS condition. This is where TCP Cubiwood comes to the rescue with an improvement of 189%in a simulated static NLoS scenario with results comparable to Cubic in wired conditions as well, thus becoming a suitable contender for replacing the historical algorithm. Delayed Congestion Response (DCR) tries to make TCP more robust towards channel errors in wireless networks so we also propose an additional flavor of Cubiwood, called Cubiwood-DCR which increases performance slightly in both wired and wireless high frequency scenarios. We extensively evaluate Cubiwood against Cubic, both with and without DCR enabled and make our code available for reproducibility and further research in the same direction. Moreover, the simplicity of this method makes our proposal a much more attractive solution. We believe the proposed solution is easy to implement, can replace Cubic and has the potential to improve performance in THz communication as well which is one of the competing spectrum bands for 6G networks.

In the realm of NLP, sentiment analysis is an indicator for identifying emotions in human language. Compared to the English language, research on low-resource languages like Bengali has not reached its full potential yet. This study evaluates the performance of CountVectorizer and Tf-Idf vectorizers to analyze sentiment in Bengali text accurately. Here we have applied SVM, MNB, RF and Xgb to the self-generated Bengali text dataset to evaluate the effectiveness of these feature extraction techniques. These techniques transform Bengali text into numerical representations for precise sentiment classification, addressing challenges like morphological complexity and syntactic nuances, highlighting the need for accurate representation of the text's sentimental features. Before applying machine learning algorithms, the dataset is preprocessed by utilizing several text preprocessing techniques to enhance its performance. We have obtained the highest accuracy of 91.15% with the MNB using the CountVectorizer strategy, outperforming the Tf-Idf slightly, which reached the accuracy of 91.00% is obtained with the MNB. The overall accuracy with CountVectorizer is 85.38%-91.15% and with Tf-Idf is 85.34% -91.00%. It is also observed that CountVectorizer has performed better than Tf-Idf comparatively. Eventually, the findings highlight the strengths and limitations of each technique, which are imperative for future research and study in NLP for Bengali. This work advances Bengali sentiment analysis and improves sentiment analysis's accuracy by determining the most effective feature extraction method.

Automatic colorization of grayscale images defies simple evaluation by quantitative metrics because there can be multiple equally good but different “truths,” making consistent evaluation challenging. To address this problem, we propose an evaluation model for image colorization that utilizes prompt learning, with novel components Color-Query Cross Attention Block and addition of Positive and Negative input images, based on the prior knowledge CLIP possesses. This complements conventional metrics by evaluating naturalness of the colorization based on the scene content.

Recognizing and preserving traditional art and craft is essential to save cultural heritage and gain global acceptance. To promote our culture and tradition worldwide, this research uses deep learning methods to classify traditional art and craft products from Bengal. We scraped 1,872 photos from online and divided into nine categories to create the dataset. Our methodology includes 80:20 train-test, data labelling, and image augmentation. Apart from that we trained InceptionResNetV2, Xception and VGG16. The Inception-ResNetV2 outperformed all other models with an accuracy of 95.73%. Model performance was measureable via metrics like confusion matrices, classification report and train & validation accuracy loss curve. The results demonstrate the impressive adaptive capabilities of transfer learning models spotting the items of traditional art and craft using InceptionResNetV2.

In the digital era where Industrie 4.0 has emerged, most of the application are either web based or mobile based and also, people are becoming very specific in selecting their products and amenities over internet. This preference in choices of users makes it difficult for the service provider to understand which product or service they should provide to the user so that the user can select appropriately and that too in less time. This has led to the use of recommendation system for these purposes. Also, the recommendation system helps manufacturers to understand that which product has higher consumption and which product has lower consumption. This paper tries its best to first explain the foundation concept of recommendation system and its forms. Also, the paper tries its best to deep dive into all the relevant research that has been carried out to understand the merits as well as limitation of if recommendation system. This work deals with various machine learning algorithms such as Neural Collaborative Filtering (NCF), Embedding Layers, Deep Neural Networks (DNN), Matrix Factorization, Hybrid Model: Collaborative Filtering (SVD), Content-Based Filtering. The paper also highlights the vital applications of recommendation system that are useful in real life.
