YouTube is one of the most widely used and technically advanced commercial systems of recommendations. It provides an overview of the system and highlights the remarkable gains in efficiency made possible by deep learning. This research uses the traditional “two-stage” framework for separating and retrieving information. First, a profound model for generating candidates ought to be described, and then a model for ranking candidates ought to be outlined, and both of these should be done in that order. The order in which these two tasks ought to be completed is important. In addition, it offers instruction that can be put into practice as well as valuable insights that have been gleaned from the process of developing, iterating, and managing a large-scale recommendation system that has a significant impact on the experience of the user.

In computing science (CS) education, software programming and software engineering subjects are parts of core CS subjects where students learn various programming languages and software development life cycle (SDLC). With the aim of equipping students with the necessary project skills and experiences essential for workplaces, Institutes of Higher Learning (IHL) have increasingly adopted the educational practice of bringing real-world team-based projects in the curriculum. Such software projects commonly support the use of Agile process practices, which place more emphasis on communications and teamwork among students in a team, stakeholders and industry customers. This could be manageable for small scale projects where student teams are in their learning journey with active and continuous communications with customers, while developing the necessary cohesion within the team to facilitate incremental deliverables of their software products. However, teamwork remains a bottleneck that is difficult to be consistently realized among members in group projects. It is not easy to motivate and measure all team members working towards the common goals or complete project tasks on time. As such, this paper proposes the Weekly Team Assessment (WTA) framework to continuously encourage teamwork throughout the software project development duration. We also propose the settings of dedicated leadership and constructive feedback iteratively in the WTA framework. The proposed methods have been applied and evaluated through the experiments in two software engineering modules, Professional Software Development and Team Project, involving 50 sophomore CS students who are divided into control group and experimental group equally. Experiment results are analyzed and discussed in this paper. Positive outcomes are observed from the experiment where about 72% of participants appreciate the proposed methods in improving their teamwork in group projects. The degree of effectiveness of the prop

The rapid development of artificial intelligence (AI) demands the enhancement of domain-specific hardware specifically designed for AI applications. Although the depth of hardware acceleration methods has been dug deeply to tickle this problem, a comprehensive review is not enough to get a detailed knowledge of these cutting-edge techniques. This paper proposes the direction and challenges of different chip designs in the present. In general, the AI chip refers to a chip that has been specially designed for and used in the field of AI algorithms. The frameworks and characteristics of the hardware accelerators based on conventional von Neumann architecture are described as the basic methods. In addition, the amount of data has shown explosive growth, where the traditional computing architecture cannot support the massive transition requirement of the data between computing processor and memory. Inference efficiency becomes the major design consideration for modern machine learning accelerators. The throughput and energy consumption were mainly determined by the efficiency of performing multiply-and-accumulate (MAC) during inference, and new insight to address this problem was provided by a process-in-memory (PIM) method. Finally, inspired by the physiological principle, a pathway of brain-inspired computing becomes an energy-efficient approach to AI computing workloads. The development of various brain-inspired chips based on non-volatile memory is reviewed in this paper, focusing on computing density, energy efficiency, computing accuracy, on-chip learning capability, and co-design principles, from the device to the algorithm level.

In recent trends, data security is considered one of the most crucial portions of big data analysis. The applications of big data manage sensitive data including medical, business, and personal records. One of the largest software systems for distributing data to process and manage huge quantities is Hadoop. Threats could comprise the cloud system utilized to store the types of cloud data. However, the primary problem of the Hadoop application is unauthorized access and took a long time to compute the data. In this research, the Elliptic Curve-Diffie-Helman (ECDH) algorithm is implemented to increase the encryption process and reduce the computation amount. First, utilize the HDFS federation and high-availability techniques to distribute the NameNode service between the servers. Then, a Zookeeper distribute coordination mechanism is employed to coordinate each node to achieve secure storage. Next, the ECDH encrypts the consistent data to adopt a homomorphic encryption algorithm which encrypts the computed data. After the ECDH process, the Perfect Forward Secrecy (PFS) encryption mode is applied to speed up the encryption process. At last, the HDFS control module design incorporates the storage model and encryption method. From the result analysis, it clearly shows that the proposed ECDH algorithm with PFS achieves better encryption time, data upload rate, and running time when compared to existing Improved Aprior and Dual Thread-Elliptic Curve Cryptography (DH-ECC).

The identification of a mathematical dynamics model is a crucial step in the designing process of a controller. However, it is often very difficult to identify the system’s governing equations, especially in complex environments that combine physical laws of different disciplines. In this paper, we present a new approach that allows identifying an ordinary differential equation by means of a physics-informed machine learning algorithm. Our method introduces a special neural network that allows exploiting prior human knowledge to a certain degree and extends it autonomously, so that the resulting differential equations describe the system as accurately as possible. We validate the method on a Duffing oscillator with simulation data and, additionally, on a cascaded tank example with real-world data. Subsequently, we use the developed algorithm in a model-based reinforcement learning framework by alternately identifying and controlling a system to a target state. We test the performance by swinging-up an inverted pendulum on a cart.

The current electric power system practices hierarchical and zonal administration to facilitate more effective monitoring of grid safety and event management. With an escalating integration of new energy sources on the generation side, the intrinsically variable nature of these resources introduces substantial uncertainties into grid operations. Meanwhile, on the demand side, load profiles are diversifying further, significantly influenced by weather conditions, market price signals, or incentive schemes, thereby adding another layer of unpredictability. Against this context, this paper proposes an intra-day rolling optimal strategy considering whole dispatch process and multi-type adjustable measures. By synthesizing regulating resources from both the source and load sides, it undertakes a series of intra-day rolling optimization decisions across the entire dispatch workflow. This strategy aims to harmonize and optimize the allocation of various resources, thereby ensuring the secure and stable functioning of the electrical grid amidst the complexities introduced by the integration of intermittent renewables and the dynamics of diversified loads.

The paper describes the process of the information objects classification in e-learning systems using the mathematical background of fuzzy logic. This approach can be used to improve the process of searching and organizing information in e-learning systems. As the volume of educational materials grows, it becomes more and more difficult to find and structure information. Fuzzy logic helps to optimize the search, and the use of a neural network can correctly classify materials in e-learning systems, which increases the efficiency and accuracy of search queries.

State of the art test case generation tools vary in the way they exploit knowledge of the system under test. While experimental results demonstrate that such knowledge can improve the efficiency of the test case generation process, how to (automatically) retrieve and integrate such information in test generation is non-trivial. Especially, in the case of Cyber-Physical Systems (CPS), the problem is more challenging since CPS have not only software requirements but also physical functional requirements. In this work, we instrument a system's source code to extract run-time information related to the behavior of the system to determine the path taken through the source code itself. Given our focus on CPS, this information enables us to compute a metric representing the total coverage of the system behaviors for a series of inputs. We present the framework to instrument the code, and our method for using the instrumented code to calculate coverage-related robustness. We also demonstrate how to integrate this approach into a search to generate tests that can manage the trade-off between code coverage and identification of functionally unsafe behaviors (falsification). Our results show that our approach is more efficient than Uniform Random sampling in covering CPS operating modes (code). In addition, we show that our approach promotes better falsifications when violating inputs are present in a, possibly small, subset of the CPS states.
