Once More Around the Park: A Baseball Reader

為了解決Observe的問題，作者Angell, Roger 這樣論述：

The most celebrated baseball writer of our time has selected his favorite pieces from the last forty years to create Once More Around the Park, a definitive volume of his most memorable work. Mr. Angell includes writing never previously collected as well as selections from The Summer Game, Five S

easons, Late Innings, and Season Ticket. He brings back the extraordinary games, innings and performances that he has witnessed and written about so astutely and gracefully--＂The Interior Stadium,＂ on the complex attractions of baseball; ＂In the Country,＂ on a friendship that began with a fan letter

and took him far from the big stadiums and big money; ＂The Arm Talks,＂ on contemporary pitching strategy and the arrival of the split-finger delivery; and many others. Mr. Angell’s conversations with past and present players and managers, scouts and coaches, rookies and Hall of Famers enhance his o

wn expertise and critical appreciation, which define him as the game’s most useful and ardent fan. ＂Angell resembles a pitcher with pinpoint control. As a chronicler of the game, he’s in a class with Ring Lardner and Red Smith.＂--Newsweek. ＂Angell’s perceptions are fresh, vivid, and uncannily accura

te.... Only a fan who cares this much could observe so carefully and write so eloquently.＂--San Francisco Chronicle. ＂A triumph of art and grace.＂--Chicago Tribune Book World. In the course of a well-lived century, he established himself as. . .baseball’s finest, fondest chronicler. --The New Yorker

What puts Once More Around the Park on the big-league shelf is, above all, language and, after that, respect for the individuality and awe for the professionalism of its characters. Mr. Angell makes baseball sound like an art form; he demonstrates that writing about it is an art form, too.＂ --New Y

移動平均線搭配馬丁停損利策略之績效研究

為了解決Observe的問題，作者嚴楦鈞 這樣論述：

智能自動交易系統，透過自定義的交易策略代替投資者在市場進行交易，在整個交易操作期間投資者無須介入交易，排除投資者情緒影響的交易操作，更能嚴守交易紀律，驗證單純以技術分析取得的績效成果。本研究針對使用技術指標-移動平均線為進場訊號，配合止盈與止損輔助做為出場方針，將其績效做為基本對照組，再與添加馬丁格爾做為進場資金的策略進行對比績效之差異。經研究結果發現添加馬丁格爾策略做為進場資金的投入後，有利提升獲利之穩定性，並降低面臨的虧損風險。

Corporate Governance in Latin America: A Comparative Analysis

為了解決Observe的問題，作者 這樣論述：

Grounded in institutional theories, this volume offers a framework for understanding the evolution of corporate governance in the six leading Latin American countries, namely Argentina, Brazil, Chile, Colombia, Mexico, and Peru.Applying inductive qualitative methods, it postulates the notion of g

overning as a dynamic, emergent and contextual process and traces its evolution and adaption to the different configurations of institutional logics in each country and the region as a whole over several decades.Adopting corporate governance scandals as the lens through which to observe institutiona

l change in each country, this book reveals the sources of societal transformations, identifying key lessons as well as meaningful setbacks along the way.This edited collection helps appreciate the role and interactions of corporate elites, stakeholders and watchdogs, including the visible hands of

government and multinational corporations, presenting comparisons across the countries, the region and the broader evolution of governing practices around the globe.The result is a book combining scholarly rigor and practical relevance, looking to serve as an emerging markets benchmark guide for pra

ctitioners, researchers and thinktanks alike.

貝氏最佳化的小樣本採集函數學習

為了解決Observe的問題，作者謝秉瑾 這樣論述：

貝氏最佳化 (Bayesian optimization, BO) 通常依賴於手工製作的採集函數 (acqui- sition function, AF) 來決定採集樣本點順序。然而已經廣泛觀察到，在不同類型的黑 盒函數 (black-box function) 下，在後悔 (regret) 方面表現最好的採集函數可能會有很 大差異。 設計一種能夠在各種黑盒函數中獲得最佳性能的採集函數仍然是一個挑戰。 本文目標在通過強化學習與少樣本學習來製作採集函數(few-shot acquisition function, FSAF)來應對這一挑戰。 具體來說，我們首先將採集函數的概念與 Q 函數 (Q

-function) 聯繫起來，並將深度 Q 網路 (DQN) 視為採集函數。 雖然將 DQN 和現有的小樣本 學習方法相結合是一個自然的想法，但我們發現這種直接組合由於嚴重的過度擬合(overfitting) 而表現不佳，這在 BO 中尤其重要，因為我們需要一個通用的採樣策略。 為了解決這個問題，我們提出了一個 DQN 的貝氏變體，它具有以下三個特徵: (i) 它 基於 Kullback-Leibler 正則化 (Kullback-Leibler regularization) 框架學習 Q 網絡的分佈(distribution) 作為採集函數這本質上提供了 BO 採樣所需的不確定性並減輕了

過度擬 合。 (ii) 對於貝氏 DQN 的先驗 (prior)，我們使用由現有被廣泛使用的採集函數誘導 學習的演示策略 (demonstration policy)，以獲得更好的訓練穩定性。 (iii) 在元 (meta) 級別，我們利用貝氏模型不可知元學習 (Bayesian model-agnostic meta-learning) 的元 損失 (meta loss) 作為 FSAF 的損失函數 (loss function)。 此外，通過適當設計 Q 網 路，FSAF 是通用的，因為它與輸入域的維度 (input dimension) 和基數 (cardinality) 無 關。通過廣

泛的實驗，我們驗證 FSAF 在各種合成和現實世界的測試函數上實現了與 最先進的基準相當或更好的表現。
