阿里巴巴 AI 「看圖回答」 測驗擊敗微軟、臉書、特斯拉,準確率還首次超越人類!

2021-08-25
看圖回答問題是人類生活及溝通的基本條件,但是對 AI 來說卻是一項高難度任務。
阿里巴巴達摩學院打造出來的 AI 語言模型 AliceMind,幾天前首度打破圖像問答(VQA)世界紀錄,答題準確率甚至超越人類基準,並且擊敗同樣有參加挑戰的微軟、FB 隊伍,象徵達摩學院的人工智慧技術邁出關鍵一步。
VQA 挑戰是什麼?
圖像問答(Visual Question Answering)挑戰的緣起,是因為國際電腦視覺與技術辨識大會 (Conference on Computer Vision and Pattern Recognition,CVPR)希望鼓勵企業攻克 AI 多模態機器學習(MultiModal Machine Learning)的難題,因此從 2015 年開辦 VQA 挑戰賽,吸引來自世界各地的網路企業、科研單位參賽。
今年的 VQA 挑戰賽和往年一樣,題庫包含了超過 25 萬張真實照片,總共有 110 萬道題目。這些題目會考驗 AI 是否能辨別圖像,比如說在一張人群的照片中算出有幾個兒童、或是在圖片中辨認出書桌上的車鑰匙,進而推測房間主人是有車的。
VQA 技術已經被廣泛導入阿里巴巴平台,像是它的 AI 客服機器人「小蜜」(Alime)就已經被淘寶、天貓商家等電商平台採用。消費者輸入問題後,AI 客服會根據商品資訊和顧客問題給出答案。
另一方面,VQA 技術不僅能運用在電商,還可用於醫學圖像辨識,以及電動車的智慧駕駛分析。
阿里巴巴的 AI 模型為何成績能夠超越人類?
這幾年人工智慧(AI)逐漸滲透到各行業,也推動更多科技革命,AI 技術逐漸成為企業數位轉型、對抗疫情,並讓經濟重返正軌的重要力量。
由阿里巴巴達摩學院打造的 AI 深度語言模型系統 AliceMind 在這次的 VQA 測驗中,答題準確率拿到 81.26%,首次超越了人類答題的準確率 80.83% ,更讓馬雲投資的達摩學院在 AI 發展上取得重大進展。
AliceMind 採用了多種專有技術,包括多樣化的視覺表示(diverse visual representations)、「多模態」預訓練語言模型(multimodal pretrained language models)、「跨模態」語義融合和對齊技術( adaptive cross-modal semantic fusion and alignment technology)。這些技術不僅可以讓阿里巴巴的 AI 理解問題並分析圖像,還可以讓 AI 用近似人類的語感回答問題。
阿里巴巴達摩院自然語言處理(NLP)負責人 Si Luo 表示:「這代表我們在『機器學習』領域又取得了一個重要里程碑,AliceMind 在視覺與文本的『多模態』理解及推理上,測試分數媲美人類認知水準,彰顯了我們研發 AI 的努力成效。」
打造出這款 AI 模型的達摩學院是什麼來歷?
2017 年,馬雲認為阿里巴巴應該要把眼光放遠,致力解決未來世界經濟、社會等問題,在此願景下成立了研究單位「達摩學院」( DAMO Academy),號稱要在 3 年投入超過 1000 億人民幣,將重點放在基礎科學和顛覆式技術創新研究上。
Si Luo 表示,人工智慧分為運算智慧、感知智慧、認知智慧及創造智慧 4 個層次。這次 AliceMind 參與的 VQA 測試內容屬於認知智慧部份。
負責人也補充說,這不代表有一天我們會被機器人取代,反而這些智慧機器可以用來輔助我們的日常工作和生活,因此人們可以很專注在他們擅長的創作上。

This week I learned to speak Punjabi then spoke it in Indian restaurants and bazaars – people were totally shocked! India is actually one of the world’s most linguistically diverse countries – in addition to Hindi and English, hundreds of other languages are spoken, including, in a small corner of northern India, the Punjabi language. The Punjabi people live spread across both India and Pakistan and have a rich and beautiful culture with incredible food, music, and religion. And here in New York City if you head to Punjab Avenue in Queens you’ll find a small but thriving community of Punjabis, particularly Punjabi Sikhs but also Hindus, Muslims, and Christians as well. So this week I brushed up on my Punjabi and headed out there to chat with the locals, who are wonderfully encouraging when it comes to learning their language. What an experience speaking Punjabi as a foreigner!

Language community, it's time we get back to the heart of what it means to be a polyglot and not hold back on sharing more linguistically diverse content. How can we foster a more supportive, accessible and diverse community? ?
There are so many "Polyglot speaks X language" videos but not many that actually share the process and progress behind it. Why are we worried that uploading a video in another language will not get as many views as in English? Isn't language diversity worth more than views? ? ... and yes, that's exactly why this entire video is in Afrikaans! ??
It's not easy and there are so many factors to take into consideration - I feel the struggles too! What are your thoughts? ? (Press CC for English subs)

Cathy Vatterott(2018)Rethinking Homework: Best Practices That Support Diverse Needs (English Edition)2nd Edition こちら、バターロットさんの本には、序文にいきなり Since the first edition of this book was published in 2009, much has changed, but the controversy surrounding homework has not abated. Research has still been unable to show proof of homework's benefit. と書いてあるのが面白いです。この本は宿題に関する様々な研究を紹介する決定版的な本ですが、初版からほぼ10年経過し、宿題に関しては様々な研究が出たものの、宿題のメリットはまだ見つかっていない。ということが前提で考察されています。
