摘要: 今天在學校又雙提到了 Deep Reinforcement Learning That Matters 這篇打響 DRL(Deep Reinforcement Learning, 深度強化學習)勸退第一槍的文章後,回來以後久違刷了一下推特,看到了這篇爆文 Deep Reinforcement Learning Doesn't Work Yet,或可直譯爲深度強化學習還玩不轉或意譯爲深度強化學習不能即插即玩。

Big data has both high volume and high velocity – one way this manifests is as silos of in-situ data representing departments in banks that are very difficult to move and integrate to obtain a single coherent customer view. Further, the ability to perform data analytics – dynamically and in near real-time – of rapidly changing customer and market data is increasingly critical for competitiveness. By considering the distributed nature of financial data storage and the velocity of financial markets, the objective of this RP is to develop distributed and real-time machine learning methods to identify decentralised and dynamic models for financial analysis, prediction, and risk management.

This project will develop (i) methods to identify cross-effects between different data resources, regions, sectors, and markets, (ii) distributed versions of methods to identify decentralised models that include individual local model components learned from local resources and cross-impact model components learned from data resources in other regions/sectors/markets, and (iii) real-time learning methods to update decentralised models and address financial market velocity.

Based on the distributed and cloud computing infrastructure, this approach should address the weakness of existing data-centralised and off-line machine learning methods, which fail to consider the cost of data transportation, storage, and fast timevarying characteristics of financial markets. The originality of this approach is its dynamic integration, by distributed and real-time mining, to maximise the effectiveness and efficiency of big data analysis.

摘要: 通過深度學習技術,物聯網(IoT)設備能夠得以解析非結構化的多媒體數據,智能地響應用戶和環境事件,但是卻伴隨著苛刻的性能和功耗要求。本文作者探討了兩種方式以便將深度學習和低功耗的物聯網設備成功整合。

摘要: Despite big data currently ranking among top business intelligence and data analytics trends, businesses continue to suffer from a lack of data-savvy talent. Research from BARC shows half of respondents reporting a lack of analytical or technical know-how for big data analytics. This is good news for tech beginners, however, whose knowledge and skills are being welcomed by companies who want to reap the benefits of big data.

摘要: 筆記本電腦、智能手機、傳感器,都為物聯網帶來了大量數據。這是獲得競爭優勢(或者保持競爭力)的重大機遇,前提是企業足夠靈活,可以管理好數據並把數據變​​成有用的商業智能。 人腦能高效地處理視覺圖像。在這個過程中,大腦使用了潛意識,讓決策者可以通過迅速掃描圖像來處理信息。可視化圖表利用了大腦的圖像識別能力,出色的可視化模型將成為處理龐大數據集的更好選擇,也是2018年重要的大數據趨勢之一。

摘要:儘管很多NoSQL 數據庫近幾年大放異彩,但是像MySQL 這樣的關係型數據庫依然是互聯網的主流數據庫之一,每個學Python 的都有必要學好一門數據庫,不管你是做數據分析,還是網絡爬蟲,Web 開發、亦或是機器學習,你都離不開要和數據庫打交道,而MySQL 又是最流行的一種數據庫,這篇文章介紹Python 操作MySQL 的幾種方式,你可以在實際開發過程中根據實際情況合理選擇。

 

摘要: 近日,有越來越多的學者正在探討機器學習(和深度學習)的侷限性,並試圖爲人工智能的未來探路,紐約大學教授 Gary Marcus 就對深度學習展開了系統性的批判。此前,圖靈獎獲得者,UCLA 教授 Judea Pearl 題爲《Theoretical Impediments to Machine Learning with Seven Sparks from the Causal Revolution》的論文中,作者就已探討了當前機器學習存在的理論侷限性,並給出了面向解決這些問題,來自因果推理的七個啓發。Pearl 教授在 NIPS 2017 系列活動中對本文進行了討論,隨後,他也對一些人們關心的問題進行了解答。
