模型微调(Fine-tuning)是什么,一文看懂

What is Fine-tuning, in one article?

Model fine-tuning (Fine-tuning) is a specific implementation of transfer learning in machine learning. The core process is based on pre-trained models, which utilize large-scale datasets to learn generic patterns and develop extensive feature extraction capabilities. The fine-tuning phase then introduces task-specific datasets to ...

朴素贝叶斯(Naive Bayes)是什么,一文看懂

What is Naive Bayes in one article?

The Naive Bayes algorithm is a supervised learning algorithm based on Bayes' theorem. Naive Bayes is based on Bayes' theorem. The "naive" part is the assumption that the features are conditionally independent of each other. Simplifying the assumptions greatly reduces the computational complexity and makes the algorithm efficient in practical applications.

提示工程在大语言模型中应用的必要性

The Need for Cue Engineering in Large Language Modeling

The following focuses on the basic idea of hint engineering and how it can improve the performance of the Large Language Model (LLM)... Interfaces for LLM: One of the key reasons why large language models are so hot is that their text-to-text interfaces enable a minimalist operational experience. In the past, using deep learning to solve any...

交叉验证(Cross-Validation)是什么,一文看懂

Cross-Validation (Cross-Validation) is what, an article to see and understand

Cross-Validation is a core method for assessing the generalization ability of a model in machine learning.The basic idea is to split the original data into a training set and a test set, and to obtain more reliable performance estimates by rotating the use of different data subsets for training and validation. This approach simulates ...

正则化(Regularization)是什么,一文看懂

Regularization (Regularization) is what, an article to see and understand

Regularization is a core technique in machine learning and statistics to prevent model overfitting. Regularization controls the degree of fitting by adding a penalty term to the objective function that is related to the complexity of the model. Common forms include L1 and L2 regularization: the L1 produces sparse solutions and applies...

前馈神经网络(Feedforward Neural Network)是什么,一文看懂

What is Feedforward Neural Network (FNN) in one article?

Feedforward Neural Network (FNN) is the basic and widely used artificial neural network model. The core feature is that the connections in the network do not form any loops or feedback paths, and the information flows strictly unidirectionally from the input layer to the output layer, after a...

决策树(Decision Tree)是什么,一文看懂

Decision Tree (Decision Tree) is what, an article to see and understand

Decision Tree (DT) is a tree-shaped predictive model that simulates the human decision-making process, classifying or predicting data through a series of rules. Each internal node represents a feature test, branches correspond to test results, and leaf nodes store the final decision. This algorithm uses a divide-and-conquer strategy...

Grid Search (Grid Search) what is it, an article to see and understand

Grid Search is an automated method for systematically finding optimal hyperparameter combinations in machine learning. This method exhausts all possible parameter combinations by predefining a range of candidate values for each hyperparameter, training the model one by one and evaluating the performance, and ultimately selecting the best-performing hyper...

K均值聚类(K-Means Clustering)是什么,一文看懂

What is K-Means Clustering (K-Means Clustering), in one article

K-Means Clustering (K-Means Clustering) is a classical unsupervised machine learning algorithm. It is mainly used to divide a dataset into K disjoint clusters. The goal of the algorithm is to assign n data points to the K clusters so that each data point belongs to the cluster corresponding to its nearest cluster center.
