Synthetic data generation has emerged as a crucial topic for financial institutions, driven by multiple factors, such as privacy protection and data augmentation. Many algorithms have been proposed for synthetic data generation but reaching the consensus on which method we should use for the specific data sets and use cases remains challenging. Moreover, the majority of existing approaches are "unsupervised" in the sense that they do not take into account the downstream task. To address these issues, this work presents a novel synthetic data generation framework. the framework integrates a supervised component tailored to the specific downstream task and employs a meta-learning approach to learn the optimal mixture distribution of existing synthetic distributions.

For machine learning tasks, the explosive growth of data makes feature selection be an essential preprocessing step, as it improves generalization capability, reduces run-time and model's complexity. Traditional feature selection methods select the informative subset to facilitate the classification accuracy. However, in real applications, the cost of collecting the features shall be taken into account. this paper proposes a new costsensitive feature selection method based on an adaptive optimization framework. Unlike most of the existing methods simply adding or deleting features one by one, the proposed method uses an adaptive swarm intelligence algorithm to search the optimal subset. this algorithm achieves a more reasonable balance between the exploration and exploitation utilizing a cosine congestion factor, and is employed in cost-sensitive feature selection problem. Both of test cost and misclassification cost are considered, then a new and more reasonable comprehensive evaluation criteria is proposed. Experimental results on benchmark datasets demonstrate the effectiveness of the proposed methods.

In an era where information technology is increasingly prevalent, music score recognition, as a vital branch of intelligent audio processing, has garnered significant attention. It not only enhances the listening experience for users but also holds substantial importance in realms such as music copyright protection, automatic scoring, and intelligent editing. the advent of deep learning technologies in computing resembles a revolution, transforming traditional audio analysis methods and rendering the processing of complex audio data more efficient and precise. By leveraging advanced deep learning models like Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), and Deep Belief Networks (DBN), researchers can extract valuable insights from vast troves of musical data, gradually uncovering the underlying patterns hidden within notes and melodies. Particularly when confronted with an array of diverse forms and styles in musical compositions, deep learning techniques significantly enhance the accuracy and speed of score recognition, revealing extraordinary potential in applications such as automatic tagging, recommendation systems, and real-time audio processing.

Withthe rapid development of Internet technologies, the Internet of things (IoT) has become a crucial bridge connecting the physical and digital worlds. As a significant branch of IoT applications, smart homes focus on automating and intelligently controlling the home environment through the interconnection and data exchange of smart devices. However, as the complexity of smart home systems increases, ensuring their efficient operation and meeting users' personalized needs has become a focal point of research. Digital twin technology, as an innovative solution, involves creating virtual replicas of physical entities to simulate, analyze, and optimize systems without disrupting their operations. this paper proposes a smart home control system design based on digital twins, aiming to achieve precise monitoring and intelligent control of the smart home environment through a highly integrated system architecture and modular design. this system not only improves energy efficiency but also autonomously learns from user behavior and preferences, thus offering more personalized services.
