Article Introduction：Nowadays, many cities in China have subways, BAT or trams, and even buses. When we need to check the bus and subway routes for travel, we need a tool to help everyone. Downloading an app just to check the subway is quite memory and capacity intensive, especially for a user whose iPhone only has 16GB. So today we will introduce to you a new subway travel guide applet. The "Check Subway" applet can query subway lines, entrances and exits, operating hours and surrounding information about food, drink and entertainment in major cities without using any data. The biggest highlight of the mini program is that it consumes very little traffic to check surrounding subway stations and make route plans for you, which is very convenient for travel. This article focuses on analyzing the main functions of this WeChat applet, as well as the corresponding data interface and the adopted applet.

Article Introduction：1. How to choose the appropriate computer power supply? The power supply calculator helps you do it with one click. When assembling a computer, choosing the appropriate power supply is a very important step. A power supply that is too low will cause the system to fail to start normally, while a power supply that is too high will cause a waste of resources. So, how can we accurately calculate the power supply required by the computer? Let's introduce the calculation method of power supply power in detail, as well as a practical computer power supply calculator. Importance of Computer Power Supply The power supply is the heart of the computer system, providing the required power for the entire system. A power supply that is too low may cause the system to fail to start normally, or even cause problems such as unexpected shutdown during use. If the power supply power is too high, it will cause a waste of resources, which will not only increase the electricity bill, but also reduce the energy consumption.

Article Introduction：In recent years, with the rapid development of technologies such as the Internet of Things and artificial intelligence, autonomous vehicles have gradually entered people's field of vision. Driverless cars not only bring convenience and comfort, but can also greatly reduce traffic accidents, improve air quality, and reduce fuel consumption. However, there are still many technical problems that need to be solved in the field of autonomous driving before full commercialization can be achieved. Among them, trusted computing technology is a crucial part of the autonomous driving field. Trusted computing technology refers to computing technology that can ensure the safety and reliability of computing processes and computing results. In the field of autonomous driving

Article Introduction：1. Generator 1. Generator is defined in Python. The mechanism of calculation while looping is called generator: generator 2. List of meanings of generator existence. All data is in memory. If there is a large amount of data, it will consume a lot of memory. . For example: only the first few elements need to be accessed, then all the subsequent space will be wasted. If the list elements are calculated according to a certain algorithm, subsequent elements can be continuously calculated during the loop, so that there is no need to create a complete list, thus Save a lot of space. 3. Method 1 of creating a generator (generator expression) The generator expression is very simple. Just change [] in a list comprehension to () to create a generator (generator): L=[x*x

Article Introduction：Training large language models (LLMs) is a computationally intensive task, even those with "only" 7 billion parameters. This level of training requires resources beyond the capabilities of most individual enthusiasts. To bridge this gap, parameter-efficient methods such as low-rank adaptation (LoRA) have emerged, allowing fine-tuning of a large number of models on consumer-grade GPUs. GaLore is an innovative approach that uses optimized parameter training to reduce VRAM requirements rather than simply reducing the number of parameters. This means that GaLore is a new model training strategy that allows the model to fully utilize all parameters for learning and save memory more efficiently than LoRA. GaLore maps these gradients into a low-dimensional space,

Article Introduction：It has to be said that scientists have been obsessed with giving AI math lessons recently. No, the Facebook team also joined in the fun and proposed a new model that can completely automate the demonstration of theorems and is significantly better than SOTA. You know, as mathematical theorems become more complex, it will only become more difficult to prove the theorems by human power alone. Therefore, using computers to demonstrate mathematical theorems has become a research focus. OpenAI has previously proposed a model GPT-f that specializes in this direction, which can demonstrate 56% of the problems in Metamath. The latest method proposed this time can increase this number to 82.6%. At the same time, researchers say that this method takes less time and can reduce computational consumption to one-tenth of the original time compared to GPT-f. Disaster

Article Introduction：Banking institutions often understand and track customers' transactions as they use their cards. For example, if someone goes on vacation in Sweden, he can pay by credit card instead of carrying cash. However, once someone else uses it, the bank that issued the credit card cannot decide to block the transaction. After all, there is no evidence in the card swiping records that someone else misappropriated the card. Banks’ machine learning algorithms make billions of these decisions every day. This is known as the "average classification problem" in computer science, and these models must decide whether a transaction matches a customer's normal purchasing behavior. For traditional machine learning algorithms, this problem is mainly solved by profiling the consumer's payment history and other interaction information with the bank, which is a computationally intensive and imperfect process. Quantum at the forefront of technology
