java机器学习库

⑴ 有大佬吗，机器学习，可以用java吗，好多都是

您好，可以的，您想说好多都是用的python是吗？这个计算机语言是随着AI火起来的，有着简洁优美，可以起到很好的粘合作用，所以也被称为胶水语言。不过目前在企业级开发中java还是最为广泛运用的，python还是不太适合。而且，都是作为人工智能底层编程，python适合，java就不适合吗？肯定不是，用java也是可以的。

⑷ Java下有什么机器学习的工具包吗

java更有用，编程语言是技能

机器学习是赌博。现在是统计学习，显然和人的学习方式不一样。

过两年搞不下去又得换其他花样了。

人工智能一直都是方向的赌博，没人知道啥是正确方向

⑸ 相比java而言，python的优势在哪

Python语言和C、Java都不太一样，它更像是一个粘合剂，如果大家想单纯作为开发语言，还是差点意思的，但它有强大的社区支撑，涉及领域多，语言易懂，比如在运维学习中，它可以写很多脚本，它比shell更强大。

一、Python可用于Web开发

Django和Flask这样基于Python的Web框架，在Web开发中变得非常流行，这些Web框架用Python创建服务器端后端代码，这些代码在服务器上而不是在用户设备以及浏览器上前端代码运行。

为什么需要web框架呢?因为web框架让构建通用后端逻辑变得更简单了，这包括把不同的URL映射到Python代码块、处理数据块和生成用户在浏览器中看到的HTMl文件。

二、Python可用于机器学习

有一些流行的Python机器学习库和框架，其中最流行的两个时scikit-learn和TensorFlow，前者附带了一些更流行的内置机器学习算法，后者更像是个低级库，允许构建自定义机器学习算法。

刚开始一个机器学习项目，建议先用scikit-learn，如果开始遇到效率问题，建议用TensorFlow。

三、Python可进行数据分析可视化

数据可视化库之一是Matplotlib，容易上手，其他一些库入seaborn是以matplotlib为基础的，学习matplotlib可以入门学习其他库。

学习了数据分析和可视化基础知识后，在coursear和khanacadem上学习统计的基础知识也是很有帮助的。

四、Python可以编写脚本

什么是脚本编写?通常是指编写小程序以让简单任务自动化，写了个简单的程序，简单的脚本来自动完成该任务。

Python适合这种类型的任务主要是因为它有相对简单的语法并且容易编写。

⑹ 如何开始使用 Java 机器学习

说到如何开始使用 Java 机器学习这个问题，相信对于从事Java开发的人来说是非常重要的，也是这段时间几乎每个人都在谈论人工智能和机器学习，这已经不再是一个保留给科学家和研究者的秘密，而是几乎实现于每一项新兴技术中。
人类的人工智能人工智能在一段时间以来是一个广泛并且炫酷的领域，但总是感觉有点难以触及，是特意为科学家所做。如果你想创造一个人工智能系统，你必须实现你自己的核心算法，并且训练它们能识别模式，理解图像并且处理自然语言。

那么，如何使用 Java 机器学习，提升应用的机器学习能力呢?
让机器运转为了更简单的阐述，以下几个项目可以帮助你：
1.Deeplearning4J (DL4J) –开源，分布式，JVM的商业深度学习lib库
2. BID Data Project –能够运行快速、大规模的机器学习和数据挖掘的模式集合
3. Neuroph –面向对象的神经网络
DL4J – 深度学习
DL4J是一个能帮助你配置多层神经网络的工具。它为JVM提供了深度学习且伴随快速原型设计和大规模定制，同时注重比配置更多的约定。DL4J 是由Java语言编写的，可以兼容任何JVM语言。
BID Data Project (大数据项目)
大数据项目是由那些需要处理大量数据并且对性能敏感的人创建的。 UC Berkeley项目是由许多硬件、软件和设计模式集合而成，能在上使用快速、大规模的数据挖掘。
Neuroph
neuroph是用来开发常用的神经网络构架的轻量级java框架。该框架提供了一个java库以及一个GUI工具(称为easyNeurons)，你可以用它来在java项目中创建和训练自己的神经网络。
总结：每隔几年就会有些关于人工智能的新声音。这一次，它伴随着机器学习，数据挖掘，神经网络等等的强化来了，我们都很支持。这些类库开源的事实意味着这些信息和能力正待价而沽，而你所有所做的是思考拥有这个能力可以做成什么。

⑺ java中有没有类似python中sklearn这样好用的机器学习库

你好，github上面有JPMML-SkLearn

Java library and command-line application for converting Scikit-Learn pipelines to PMML.
