    Through this research, we are showcasing the application of computational approaches to the discoveries in the life sciences spectrum. Our current research not only focused on mobile genetic elements but also developed the computational methods that enabled these findings. We combined the biology sciences and computer science in our research, which is essentially multidisciplinary. To that end, this research intricately probed the role and implications of mobile genetic elements, emphasizing transposable elements. These dynamic components wielded substantial influence over genomic architecture\u27s structure, function, and evolutionary adaptations. An integral component of our study is the innovative computational tool, Target/IGE Retriever (TIGER), employed to detect and map these mobile genetic elements. Given the pronounced impact of these elements on gene regulation and their involvement in various genetic diseases, their precise detection and mapping within a genome were crucial for understanding intricate genetic dynamics and disease etiology. Addressing computational challenges, the study introduces three new algorithms to enhance TIGER\u27s performance, tested using E. coli genomes. This testing aimed to determine the impact of database size reduction on result accuracy and performance. Findings indicate that while prophage yields are less affected by database size, non-phage islands show sensitivity, suggesting performance improvements with smaller databases. Furthermore, the research conducts a comparative analysis of TIGER and BLAST outputs, focusing on validating transposons identified in E. coli genomes. This involves cross-referencing with established databases and employing statistical methods for match categorization, enhancing the authenticity of transposon location identification.. Within the purview of this rigorous analytical process, particular attention is accorded to evaluating sequence alignment results and the quality of BLAST hits, focusing specifically on identifying direct repeats within insertion sequences. The study underscores TIGER\u27s efficacy in transposon discovery and yields critical insights into its performance relative to BLAST. This research illuminates potential avenues for enhancing computational tools in bioinformatics, all within the larger framework of contributing significantly to genomics and bioinformatics research\u27s ongoing advancements. Our work deepens our understanding of the role and influence of mobile genetic elements on genomic architecture.

    Body language (BL) refers to the non-verbal communication expressed through physical movements, gestures, facial expressions, and postures. It is a form of communication that conveys information, emotions, attitudes, and intentions without the use of spoken or written words. It plays a crucial role in interpersonal interactions and can complement or even override verbal communication. Deep multi-modal learning techniques have shown promise in understanding and analyzing these diverse aspects of BL. The survey emphasizes their applications to BL generation and recognition. Several common BLs are considered i.e., Sign Language (SL), Cued Speech (CS), Co-speech (CoS), and Talking Head (TH), and we have conducted an analysis and established the connections among these four BL for the first time. Their generation and recognition often involve multi-modal approaches. Benchmark datasets for BL research are well collected and organized, along with the evaluation of SOTA methods on these datasets. The survey highlights challenges such as limited labeled data, multi-modal learning, and the need for domain adaptation to generalize models to unseen speakers or languages. Future research directions are presented, including exploring self-supervised learning techniques, integrating contextual information from other modalities, and exploiting large-scale pre-trained multi-modal models. In summary, this survey paper provides a comprehensive understanding of deep multi-modal learning for various BL generations and recognitions for the first time. By analyzing advancements, challenges, and future directions, it serves as a valuable resource for researchers and practitioners in advancing this field. n addition, we maintain a continuously updated paper list for deep multi-modal learning for BL recognition and generation: https://github.com/wentaoL86/awesome-body-language

    Multiple sequence alignment (MSA) is an alignment of three or more sequences. Studies show that MSA exhibits a challenge, that is, how to find the MSA that maximises the Quality (Q) score and Total Column (TC) score. This problem is an NP-complete problem. Hence, numerous researchers have devoted their efforts to tackle the MSA problem, yet, there is still a shortcoming in the accuracy

    Create and Find Flatness: Building Flat Training Spaces in Advance for Continual Learning

    Full text link
    Catastrophic forgetting remains a critical challenge in the field of continual learning, where neural networks struggle to retain prior knowledge while assimilating new information. Most existing studies emphasize mitigating this issue only when encountering new tasks, overlooking the significance of the pre-task phase. Therefore, we shift the attention to the current task learning stage, presenting a novel framework, C&F (Create and Find Flatness), which builds a flat training space for each task in advance. Specifically, during the learning of the current task, our framework adaptively creates a flat region around the minimum in the loss landscape. Subsequently, it finds the parameters' importance to the current task based on their flatness degrees. When adapting the model to a new task, constraints are applied according to the flatness and a flat space is simultaneously prepared for the impending task. We theoretically demonstrate the consistency between the created and found flatness. In this manner, our framework not only accommodates ample parameter space for learning new tasks but also preserves the preceding knowledge of earlier tasks. Experimental results exhibit C&F's state-of-the-art performance as a standalone continual learning approach and its efficacy as a framework incorporating other methods.
