「SVM (Support Vector Machine, 支援向量機)、Deep Learning 及 Neural Networks 模型的 input-output 都是向量 (vector);但實際上 input-output 型式會比 vector 更複雜;可能是sequence,list,tree,或是 bounding box…。Structured learning 是要找到一個 function,使其 input 及 output 分別都是 object。」

RL — Imitation Learning

「One of the biggest challenges is collecting expert demonstrations. Unless it has a huge business potential, the attached cost can be prohibitive. But technically, there is another major issue. We can never duplicate things exactly. Error accumulates fast in a trajectory and put us into situations that we never deal with before.」

「最大的挑戰之一是收集專家演示。除非它具有巨大的商業潛力,否則附加成本可能會令人望而卻步。但從技術上講,還有另一個主要問題。我們永遠無法完全複製事物。錯誤在一個軌跡中快速累積,並將我們置於以前從未處理過的情況中。」

A brief overview of Imitation Learning

模仿學習的簡要概述

2021/08/18

「The simplest form of imitation learning is behaviour cloning (BC), which focuses on learning the expert’s policy using supervised learning. An important example of behaviour cloning is ALVINN, a vehicle equipped with sensors, which learned to map the sensor inputs into steering angles and drive autonomously. This project was carried out in 1989 by Dean Pomerleau, and it was also the first application of imitation learning in general.」

「模仿學習的最簡單形式是行為克隆(BC),它側重於使用監督學習來學習專家的策略。行為克隆的一個重要例子是 ALVINN,一種配備傳感器的車輛,它學會了將傳感器輸入映射到轉向角並自動駕駛。該項目由 Dean Pomerleau 於 1989 年開展,也是模仿學習的第一個應用。」

「The way behavioural cloning works is quite simple. Given the expert’s demonstrations, we divide these into state-action pairs, we treat these pairs as i.i.d. examples and finally, we apply supervised learning. The loss function can depend on the application. 」

「行為克隆的工作方式非常簡單。鑑於專家的演示,我們將它們分成狀態-動作對,我們將這些對視為 iid 示例,最後,我們應用監督學習。損失函數可以取決於應用程序。」

模仿學習(Imitation Learning)介紹

2021/08/17

「在傳統的強化學習任務中,通常通過計算累積獎賞來學習最優策略(policy),然而在多步決策(sequential decision)中,學習器不能頻繁地得到獎勵,且這種基於累積獎賞及學習方式存在非常巨大的搜索空間。而模仿學習(Imitation Learning)已經能夠很好地解決多步決策問題,在機器人、 NLP 等領域也有很多的應用。」

「模仿學習是指從示教者提供的範例中學習,一般提供人類專家的決策數據,之後就可以把狀態作為特徵(feature),動作作為標記(label)進行分類(對於離散動作)或回歸(對於連續動作)的學習從而得到最優策略模型。模型的訓練目標是使模型生成的狀態-動作軌跡分佈和輸入的軌跡分佈相匹配。類似自動編碼器(Autoencoder)與 GANs。」
