Link prediction code example using Pytorch Geometric
PyTorch Geometric (PyG) is the main tool for building graph neural network models and experimenting with various graph convolutions. In this article we will introduce it through link prediction. Link prediction answers the question: Which two nodes should be linked to each other? We will prepare the data for modeling by performing a “transformation split”. […]

How to install biometric software in Linux system? A complete nanny guide
Linux biometric software installation guide There are usually multiple ways to install bioinformatics analysis software under Linux systems, including installation using package management tools (such as conda) and compilation and installation through source code. This note briefly shares the methods and techniques for installing bioinformatics analysis software under Linux. I hope it will be helpful […]
06｜Symmetric key: How to protect private data?
In the previous module, we learned about one-way hash functions. Starting today, we will open a new module, in which I will discuss with you the relevant knowledge of encryption technology. Do you feel that you still have more to learn from the previous module? Don’t worry, one-way hash functions will still appear in our […]
(Multimodal Medical) CephGPT-4: Interactive multimodal cephalometric and diagnostic system using visual large language model
Paper address Abstract In this paper, we propose a novel multimodal cephalometric analysis and diagnostic dialogue model. First, a multimodal orthodontic medical data set is constructed, including cephalometric images and doctor-patient dialogue data, and U-net is used to automatically analyze cephalometric signs and generate a diagnostic report. Then, the cephalometric data set and the generated […]

The Go standard library wants to add metrics. Do you support it?
Hello everyone, I am fried fish. In Go’s standard library, there is a magical standard library runtime/metrics. This standard library provides a series of predefined indicators related to Go itself. Friends who have not written a basic monitoring library or pay less attention may not be exposed to such indicators, or even know that these […]
