java機器學習庫

⑴ 有大佬嗎，機器學習，可以用java嗎，好多都是

您好，可以的，您想說好多都是用的python是嗎？這個計算機語言是隨著AI火起來的，有著簡潔優美，可以起到很好的粘合作用，所以也被稱為膠水語言。不過目前在企業級開發中java還是最為廣泛運用的，python還是不太適合。而且，都是作為人工智慧底層編程，python適合，java就不適合嗎？肯定不是，用java也是可以的。

⑷ Java下有什麼機器學習的工具包嗎

java更有用，編程語言是技能

機器學習是賭博。現在是統計學習，顯然和人的學習方式不一樣。

過兩年搞不下去又得換其他花樣了。

人工智慧一直都是方向的賭博，沒人知道啥是正確方向

⑸ 相比java而言，python的優勢在哪

Python語言和C、Java都不太一樣，它更像是一個粘合劑，如果大家想單純作為開發語言，還是差點意思的，但它有強大的社區支撐，涉及領域多，語言易懂，比如在運維學習中，它可以寫很多腳本，它比shell更強大。

一、Python可用於Web開發

Django和Flask這樣基於Python的Web框架，在Web開發中變得非常流行，這些Web框架用Python創建伺服器端後端代碼，這些代碼在伺服器上而不是在用戶設備以及瀏覽器上前端代碼運行。

為什麼需要web框架呢?因為web框架讓構建通用後端邏輯變得更簡單了，這包括把不同的URL映射到Python代碼塊、處理數據塊和生成用戶在瀏覽器中看到的HTMl文件。

二、Python可用於機器學習

有一些流行的Python機器學習庫和框架，其中最流行的兩個時scikit-learn和TensorFlow，前者附帶了一些更流行的內置機器學習演算法，後者更像是個低級庫，允許構建自定義機器學習演算法。

剛開始一個機器學習項目，建議先用scikit-learn，如果開始遇到效率問題，建議用TensorFlow。

三、Python可進行數據分析可視化

數據可視化庫之一是Matplotlib，容易上手，其他一些庫入seaborn是以matplotlib為基礎的，學習matplotlib可以入門學習其他庫。

學習了數據分析和可視化基礎知識後，在coursear和khanacadem上學習統計的基礎知識也是很有幫助的。

四、Python可以編寫腳本

什麼是腳本編寫?通常是指編寫小程序以讓簡單任務自動化，寫了個簡單的程序，簡單的腳本來自動完成該任務。

Python適合這種類型的任務主要是因為它有相對簡單的語法並且容易編寫。

⑹ 如何開始使用 Java 機器學習

說到如何開始使用 Java 機器學習這個問題，相信對於從事Java開發的人來說是非常重要的，也是這段時間幾乎每個人都在談論人工智慧和機器學習，這已經不再是一個保留給科學家和研究者的秘密，而是幾乎實現於每一項新興技術中。
人類的人工智慧人工智慧在一段時間以來是一個廣泛並且炫酷的領域，但總是感覺有點難以觸及，是特意為科學家所做。如果你想創造一個人工智慧系統，你必須實現你自己的核心演算法，並且訓練它們能識別模式，理解圖像並且處理自然語言。

那麼，如何使用 Java 機器學習，提升應用的機器學習能力呢?
讓機器運轉為了更簡單的闡述，以下幾個項目可以幫助你：
1.Deeplearning4J (DL4J) –開源，分布式，JVM的商業深度學習lib庫
2. BID Data Project –能夠運行快速、大規模的機器學習和數據挖掘的模式集合
3. Neuroph –面向對象的神經網路
DL4J – 深度學習
DL4J是一個能幫助你配置多層神經網路的工具。它為JVM提供了深度學習且伴隨快速原型設計和大規模定製，同時注重比配置更多的約定。DL4J 是由Java語言編寫的，可以兼容任何JVM語言。
BID Data Project (大數據項目)
大數據項目是由那些需要處理大量數據並且對性能敏感的人創建的。 UC Berkeley項目是由許多硬體、軟體和設計模式集合而成，能在上使用快速、大規模的數據挖掘。
Neuroph
neuroph是用來開發常用的神經網路構架的輕量級java框架。該框架提供了一個java庫以及一個GUI工具(稱為easyNeurons)，你可以用它來在java項目中創建和訓練自己的神經網路。
總結：每隔幾年就會有些關於人工智慧的新聲音。這一次，它伴隨著機器學習，數據挖掘，神經網路等等的強化來了，我們都很支持。這些類庫開源的事實意味著這些信息和能力正待價而沽，而你所有所做的是思考擁有這個能力可以做成什麼。

⑺ java中有沒有類似python中sklearn這樣好用的機器學習庫

你好，github上面有JPMML-SkLearn

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