AI-assisted data classification and classification
Introduction
In the era of information explosion, data has become one of the most valuable assets of an enterprise. However, if a large amount of data cannot be effectively classified and classified, it will become disordered and chaotic, data security cannot be effectively guaranteed, and its true data value cannot be exerted. Therefore, data classification and grading have become crucial for both data security and data value. This article will discuss the importance of data classification and classification, and introduce how to use machine learning to achieve intelligent classification and classification of data.
1. The importance of data classification and grading
Data classification and grading is the process of classifying and sorting data according to certain rules and standards. It can help enterprises better manage data and improve data confidentiality, availability, integrity and accessibility, thereby better supporting business decision-making and development. The following is the importance of data classification and grading: 1. Confidentiality: By classifying and grading data, data can be encrypted and permissions controlled according to different levels of sensitivity to ensure data security. 2. Availability: Through data classification and grading, we can better understand the importance and urgency of data, thereby rationally allocating resources and formulating backup strategies to ensure timely availability of data. 3. Integrity: Through data classification and grading, data can be effectively verified and verified to ensure the integrity of the data
Improve data utilization: By classifying and grading data, we can more accurately understand the nature and characteristics of the data, thereby making better use of data for analysis and mining, and improving the value and utilization of data.
Reduce data management costs: When the amount of data is large and disordered, the cost of data management and maintenance is often high. By classifying and grading data, data can be managed in an orderly manner, reducing unnecessary duplication of work and reducing data management costs.
Strengthen data security protection: Data classification and grading can provide different levels of targeted protection based on the sensitivity of the data to avoid unauthorized access. Access or disclosure by authorized personnel.
Data sharing and cooperation: On the basis of classification and grading, formulate corresponding authority management mechanisms. According to different categories and levels Authorize data to meet sharing and cooperation, and strengthen information communication.
Support business decisions: Data is an important basis for supporting business decisions. By classifying and grading data, the meaning and relevance of the data can be better understood, providing more reliable support and reference for business decisions.

Improve developer productivity, efficiency, and accuracy by incorporating retrieval-enhanced generation and semantic memory into AI coding assistants. Translated from EnhancingAICodingAssistantswithContextUsingRAGandSEM-RAG, author JanakiramMSV. While basic AI programming assistants are naturally helpful, they often fail to provide the most relevant and correct code suggestions because they rely on a general understanding of the software language and the most common patterns of writing software. The code generated by these coding assistants is suitable for solving the problems they are responsible for solving, but often does not conform to the coding standards, conventions and styles of the individual teams. This often results in suggestions that need to be modified or refined in order for the code to be accepted into the application

These questions It requires thinking outside the box. Large Language Models (LLMs) are increasingly important in the fields of data science, generative artificial intelligence (GenAI), and artificial intelligence. These complex algorithms enhance human skills and drive efficiency and innovation in many industries, becoming the key for companies to remain competitive. LLM has a wide range of applications. It can be used in fields such as natural language processing, text generation, speech recognition and recommendation systems. By learning from large amounts of data, LLM is able to generate text

Large Language Models (LLMs) are trained on huge text databases, where they acquire large amounts of real-world knowledge. This knowledge is embedded into their parameters and can then be used when needed. The knowledge of these models is "reified" at the end of training. At the end of pre-training, the model actually stops learning. Align or fine-tune the model to learn how to leverage this knowledge and respond more naturally to user questions. But sometimes model knowledge is not enough, and although the model can access external content through RAG, it is considered beneficial to adapt the model to new domains through fine-tuning. This fine-tuning is performed using input from human annotators or other LLM creations, where the model encounters additional real-world knowledge and integrates it

Editor |ScienceAI Question Answering (QA) data set plays a vital role in promoting natural language processing (NLP) research. High-quality QA data sets can not only be used to fine-tune models, but also effectively evaluate the capabilities of large language models (LLM), especially the ability to understand and reason about scientific knowledge. Although there are currently many scientific QA data sets covering medicine, chemistry, biology and other fields, these data sets still have some shortcomings. First, the data form is relatively simple, most of which are multiple-choice questions. They are easy to evaluate, but limit the model's answer selection range and cannot fully test the model's ability to answer scientific questions. In contrast, open-ended Q&A

Machine learning is an important branch of artificial intelligence that gives computers the ability to learn from data and improve their capabilities without being explicitly programmed. Machine learning has a wide range of applications in various fields, from image recognition and natural language processing to recommendation systems and fraud detection, and it is changing the way we live. There are many different methods and theories in the field of machine learning, among which the five most influential methods are called the "Five Schools of Machine Learning". The five major schools are the symbolic school, the connectionist school, the evolutionary school, the Bayesian school and the analogy school. 1. Symbolism, also known as symbolism, emphasizes the use of symbols for logical reasoning and expression of knowledge. This school of thought believes that learning is a process of reverse deduction, through existing

Editor | KX In the field of drug research and development, accurately and effectively predicting the binding affinity of proteins and ligands is crucial for drug screening and optimization. However, current studies do not take into account the important role of molecular surface information in protein-ligand interactions. Based on this, researchers from Xiamen University proposed a novel multi-modal feature extraction (MFE) framework, which for the first time combines information on protein surface, 3D structure and sequence, and uses a cross-attention mechanism to compare different modalities. feature alignment. Experimental results demonstrate that this method achieves state-of-the-art performance in predicting protein-ligand binding affinities. Furthermore, ablation studies demonstrate the effectiveness and necessity of protein surface information and multimodal feature alignment within this framework. Related research begins with "S
