Do you still search data sets on Baidu? Remember that this place has all kinds of data! In the context of increasingly pressing demand for fast access to accurate data, traditional search engines and social media platforms are often unsatisfactory due to the endless emergence of advertisements and routines. In order to solve the problem of data shortage and digital talent matching in the industry, the "cover" platform came into being. The platform gathers a large amount of data accumulated by various industries, and actively builds a bridge between digital needs and solution providers. By submitting data and providing bonus incentives, the platform encourages technicians to provide innovative solutions. In addition, the platform not only provides data resources, but also includes source code and complete project support, providing all-round support for data analysis and project development. It is suitable for professionals who are interested in data analysis, technology solution development and digital transformation. 00:36 17 thousand Overview of the overall framework of neural networks This lesson focuses on building a neural network algorithm from scratch and taking handwritten font recognition as an example for practice. The process involves input feature processing, hidden layer mapping, weight parameter matrix construction and initialization, and introduces the basic concepts of forward propagation and backward propagation. As a key step in neural network training, back-propagation is difficult and is the core of weight parameter update. Through explanation and code practice, the course gradually demonstrates how to solve multi classification problems, and provides guidance on mathematical formulas and calculation processes. The content is suitable for programmers and learners who want to deeply understand and practice in the field of neural networks. 07:30 15 thousand When running open source projects and tools, remember to look at this module first! Faced with a large number of open source projects, how to quickly evaluate the feasibility and stability of a project is a problem faced by many developers. The video introduces how to use the module named S5 to view community feedback and problem reports of open source projects, so as to help developers avoid spending a lot of time and energy on projects that are difficult to run or have defects. As a project evaluation tool, S5 module can provide the first impression of project availability in a short time, thus providing real-time basis for developers to decide whether to continue to invest resources. This process reduces the confusion and time waste caused by environment configuration, allowing developers to focus on projects with good community support and stability. 00:28 10 thousand Daily patrol inspection method of Oracle database Oracle database managers need to master the importance of daily patrol inspection and its operation process. This includes ensuring the normal operation and backup of the database, checking performance indicators and failure logs (such as ORA errors), verifying the effectiveness of indexes, monitoring the use of tablespace and operating system space, and conducting database recovery tests. These operations can be realized through patrol scripts. Also, pay attention to database performance monitoring combined with system logs. This paper demonstrates the process of using ADDM script for performance analysis, and emphasizes the necessity of handling the tasks assigned by leaders. The content is suitable for database administrators, operation and maintenance engineers, Oracle database experts, database performance tuning personnel, and IT technical support personnel. 10:00 123 thousand SQL Server 2005 Installation The video tutorial guides the audience to complete the installation process of COC2005. The installation media starts automatically, accepts the license conditions, and installs prerequisite components such as downa remark2.0 and sql native plan. Emphasize the importance of system configuration inspection, including software and hardware requirements. Describes the installation wizard operation, including registration information input, component selection, such as database service and medical service, and especially points out the IS dependency of the reporting service. Guide users to install multiple database instances through instance management, and provide account permission configuration and service startup scheme. Finally, it explains the authentication settings, including Windows authentication and mixed mode, and emphasizes the importance of setting collations. The content is suitable for database administrators, server operation and maintenance personnel, IT students, system architects, and software developers. 06:20 45 thousand Why is Python widely used in AI because of its poor performance Although Python has a lower performance than C++, it dominates the AI field because of its effectiveness and scalability as an adhesive. Python is closely integrated with C++or graphics card in terms of data interaction, which the AI industry relies heavily on. More importantly, scientists originally chose Python to replace Fortran, thus forming a strong scientific computing ecosystem. Python's mathematical libraries, such as NumPy, are widely used in scientific computing, boosting its continuation in the AI field. In fact, in the real case of a financial AI company, Python is used for rapid prototyping, and the production environment is turned to C++with better performance. At the same time, the feature of Python global lock is not a problem at the experimental stage, but the formal link needs to use C++and other languages to improve performance. 01:49 38 thousand [Workplace Secrets] How to spend the probation period safely? Come and get the "security strategy" for the trial period! The key to safely passing the probation period in the workplace is to clarify personal orientation and proactive work attitude. A successful case describes how a student with good eloquence was dismissed due to over packaging himself, resulting in mismatched positions, while a failure case describes how he was dismissed for many times due to lack of active communication and team cooperation, even though he has strong technical ability. From these cases, it can be seen that for newcomers, they should not only truly demonstrate their technical level, but also actively integrate into the team and maintain good communication with colleagues around them. In addition, timely reporting of work progress to the superior and taking the initiative to seek help when encountering problems are also important factors to ensure the smooth passing of the probation period. Adapting to the workplace requires not only solid technical skills, but also good working attitude and communication and collaboration ability. 18:38 18 thousand How does driverless driving appear? The video mainly focuses on the depth estimation technology, and discusses the technical application and importance of judging the distance of objects through the video analysis of the vehicle camera. The key of depth estimation is to recognize the distance information of each pixel in the image, generate a structure similar to the heat map, and distinguish the color depth to show the object distance. This technology is very important in scenes such as assisted driving and 3D reconstruction, and shows the use of monocular cameras in conjunction with neural network models as a cost-effective alternative to depth estimation. This content has practical guiding significance for the application scenarios that pursue technology and cost balance and for researchers or developers interested in depth perception algorithms. 07:55 16 thousand
