BigData_DW_Real Comprehensive Guide to Big Data Processing Architectures
BigData_DW_Real Document Overview
The document BigData_DW_Real.docx provides an extensive guide on big data processing architectures, covering both offline and real-time processing architectures. Additionally, it details the requirements overview and architectural design of a big data warehouse project.
Big Data Processing Architectures
Big data processing architectures are primarily classified into two types:
Offline Processing Architecture
Utilized for data post-analysis and data mining applications.
Technologies: Hive, Map/Reduce, Spark SQL, etc.
Advantages: Capable of handling large volumes of data.
Disadvantages: Slower processing speed, less sensitive to real-time demands.
Real-Time Processing Architecture
Suited for real-time monitoring and interactive applications.
Technologies: Spark Streaming, Flink.
Advantages: High responsiveness for time-sensitive data.
Disadvantages: Faster processing but limited to simpler business logic.
Big Data Warehouse Project Requirements
The big data warehouse project encompasses six key requirements:
Daily Active Users: Analysis with hourly trends and daily comparisons.
Daily New Users: Analysis with hourly trends and daily comparisons.
Daily Transaction Volume: Analysis with hourly trends and daily comparisons.
Daily Order Count: Analysis with hourly trends and daily comparisons.
Shopping Coupon Risk Warning: Function for identifying potential risks.
Flexible User Purchase Analysis: Customizable analysis functionality.
Architectural Design for Big Data Warehouse Project
Main Project (gmall): Based on Spring Boot.
Dependencies: Incorporates Spark, Scala, Log4j, Slf4j, Fastjson, Httpclient.
Project Structure: Includes parent project, submodules, and dependencies.
Technology Versions:- Spark: 2.1.1- Scala: 2.11.8- Log4j: 1.2.17- Slf4j: 1.7.22- Fastjson: 1.2.47- Httpclient: 4.5.5- Httpmime: 4.3.6- Java: 1.8

Matlab中DW检验的代码实现-RetinaFace.pytorch快速的RetinaFace工具
在Matlab中实现了DW检验的代码,并将其移植到PyTorch中的RetinaFace模型中。该模型仅有1.7M大小,支持使用mobilenet0.25或resnet50作为骨干网,以获得不同的性能结果。我们还提供了Mxnet中的官方代码。此外,我们针对移动和边缘设备提供了面向python训练到C++推理的人脸检测器。在WiderFace数据集上的性能测试显示,当使用原始比例秤时,ResNet50达到了95.48%的精度。
