Reference Guide for Metric Learning

https://qaofficial.com/post/2019/04/18/73112-reference-guide-for-metric-learning.html 2019-04-18
Reference Guide for Metric Learning metric learning refers to Distance Metric Learning, abbreviated as DML, which is widely used in image retrieval and classification, face recognition, human activity recognition and pose estimation in computer vision, text analysis and some other fields such as music analysis, automated project debugging, microarray data analysis, etc. metric learning was proposed by Eric P. Xing, Andrew Y. Ng and others in NIPS 2003. This is not a new word.

https://qaofficial.com/post/2019/04/18/73054-summary-of-image-processing-using-cnn-in-tensor-flow.html 2019-04-18
I've read a lot of books and been in actual combat, but I always want to tell the CNN process in common language. Today I have the honor to share it with you. First of all, Convolutional Neural Network is a neural network with at least one layer. The function of this layer is to calculate the convolution of input F and configurable convolution stone G to generate output.The purpose of convolution is to apply convolution stone to all points of a tensor and generate a new filtered tensor by sliding convolution stone.

In recent years, Python has become more and more popular, because Python is simple and fast to learn, and it is the preferred language for many novice programmers to get started. Python is a scripting language. Python is also called glue language because it can glue together modules written in various other programming languages.Strong inclusiveness and extensive use have attracted more and more attention. Python is very popular academically.

1. It took me more than an hour to write the summary at the beginning of yesterday morning and ended at 11: 03. During the summary of the related usage of pandas, I learned the new method of building empty dataframe and then continuously appending it. 2. After the summary, we monitored the bad debts and the running status of the model. 3. After the summary in the morning, we

Datawhale Algorithm Practice Phase 2 Task 2-Model Evaluation

Task Description Record the scoring tables of 7 models (logistic regression, SVM, decision tree, random forest, GBDT, XGBoost and LightGBM) on accuracy, precision, recall and FIA Formula 1 World Championship-score, auc values, and draw Roc curves. 1. Code Optimization-Data Set Loading because train_test_split supports inputting data in Dataframes format.Therefore, it is suggested to amend the data reading code as follows: (relatively simple) data = pd.read_csv("data_all.csv") # trai

one-versus-rest and one-versus-one are different.SVM algorithm was originally designed for binary classification problems. When dealing with multi-class problems, it is necessary to construct suitable multi-class classifiers.At present, there are two main methods for constructing SVM multi-class classifiers: one is direct method, which directly modifies the objective function, combines the parameter solutions of multiple classification flour into an optimization problem, and realizes multi-class classification "at one time" by solving the optimization problem.

OnehotEncoder's Understanding in Practical Application

Monothermal coding is to change data into (1,0,0,...,0),(0,1,0,0,...,0), and the feature attribute has as many categories as it has dimensions.LabelEncoder is to change the data into continuous numerical variables, such as "American", "Japanese" and "Chinese" originally, and (0,1,2) is usually a combination of the two. LabelEncoder sorts the data and encodes them with serial numbers.Before using onehot, you must combine the training set test sets (for example, a new label

Region Split Policy

Region concept Region is the basic element of table acquisition and distribution, and consists of one Store for each column family.The object level diagram is as follows: Region size Region size is a thorny problem, which needs to consider the following factors. Region is the smallest unit of distributed storage and load balancing in HBase.Different Region are distributed on different regional servers, but they are not the smallest units of storage.
