之前看了Mahout官方示例 20news 的调用实现；于是想根据示例的流程实现其他例子。网上看到了一个关于天气适不适合打羽毛球的例子。
训练数据：
Day Outlook Temperature Humidity Wind PlayTennis
D1 Sunny Hot High Weak No
D2 Sunny Hot High Strong No
D3 Overcast Hot High Weak Yes
D4 Rain Mild High Weak Yes
D5 Rain Cool Normal Weak Yes
D6 Rain Cool Normal Strong No
D7 Overcast Cool Normal Strong Yes
D8 Sunny Mild High Weak No
D9 Sunny Cool Normal Weak Yes
D10 Rain Mild Normal Weak Yes
D11 Sunny Mild Normal Strong Yes
D12 Overcast Mild High Strong Yes
D13 Overcast Hot Normal Weak Yes
D14 Rain Mild High Strong No
检测数据：
sunny，hot，high，weak
结果：
Yes=》 0.007039
No=》 0.027418
于是使用Java代码调用Mahout的工具类实现分类。
基本思想：
1. 构造分类数据。
2. 使用Mahout工具类进行训练，得到训练模型。
3。将要检测数据转换成vector数据。
4. 分类器对vector数据进行分类。
接下来贴下我的代码实现=》
1. 构造分类数据：
在hdfs主要创建一个文件夹路径 /zhoujainfeng/playtennis/input 并将分类文件夹 no 和 yes 的数据传到hdfs上面。
数据文件格式，如D1文件内容： Sunny Hot High Weak
2. 使用Mahout工具类进行训练，得到训练模型。
3。将要检测数据转换成vector数据。
4. 分类器对vector数据进行分类。
这三步，代码我就一次全贴出来；主要是两个类 PlayTennis1 和 BayesCheckData = =》

1. 请介绍一下WebGIS的概念和作用，以及在实际应用中的优势和挑战。
WebGIS是一种基于Web技术的地理信息系统，通过将地理数据和功能以可视化的方式呈现在Web浏览器中，实现地理空间数据的共享和分析。它可以用于地图浏览、空间查询、地理分析等多种应用场景。WebGIS的优势包括易于访问、跨平台、实时更新、可定制性强等，但也面临着数据安全性、性能优化、用户体验等挑战。
2. 请谈谈您在WebGIS开发方面的经验和技能。
我在WebGIS开发方面有丰富的经验和技能。我熟悉常用的WebGIS开发框架和工具，如ArcGIS API for JavaScript、Leaflet、OpenLayers等。我能够使用HTML、CSS和JavaScript等前端技术进行地图展示和交互设计，并能够使用后端技术如Python、Java等进行地理数据处理和分析。我还具备数据库管理和地理空间数据建模的能力，能够设计和优化WebGIS系统的架构。
3. 请描述一下您在以往项目中使用WebGIS解决的具体问题和取得的成果。
在以往的项目中，我使用WebGIS解决了许多具体问题并取得了显著的成果。例如，在一次城市规划项目中，我开发了一个基于WebGIS的交通流量分析系统，帮助规划师们评估不同交通方案的效果。另外，在一次环境监测项目中，我使用WebGIS技术实现了实时的空气质量监测和预警系统，提供了准确的空气质量数据和可视化的分析结果，帮助政府和公众做出相应的决策。
4. 请谈谈您对WebGIS未来发展的看法和期望。
我认为WebGIS在未来会继续发展壮大。随着云计算、大数据和人工智能等技术的不断进步，WebGIS将能够处理更大规模的地理数据、提供更丰富的地理分析功能，并与其他领域的技术进行深度融合。我期望未来的WebGIS能够更加智能化、个性化，为用户提供更好的地理信息服务，助力各行各业的决策和发展。
这块您需要了解下stm32等单片机的基本编程和简单的硬件设计，最好能够了解模电和数电相关的知识更好，还有能够会做操作系统，简单的有ucos，freeRTOS等等。最好能够使用PCB画图软件以及keil4等软件。希望对您能够有用。
