什么是量化交易?

　　量化交易就是以數(shù)學(xué)公式和統(tǒng)計(jì)數(shù)據(jù)等為基礎(chǔ)來建立數(shù)學(xué)模型，通過數(shù)學(xué)模型來進(jìn)行交易。Quantitative trading relies on highly developed computer and internet technologies

　　人工智能（Artificial Intelligence，簡稱AI）是指計(jì)算機(jī)系統(tǒng)在完成類似人類智力所需的任務(wù)時(shí)所表現(xiàn)出來的能力。It is a complex technology that continuously adjusts and improves its own algorithm by inputting a large amount of data into the algorithm for learning,thereby continuously optimizing its performance.
