比較遺傳演算法與強化學習: 以代理人基彩券市場為例

李家瑋 Unknown Date (has links)
在代理人基計算建模(agent-based computational modeling)被拿來廣泛應用的同時,多數學者發現模擬的結果會高度取決於人工適應性個體的設計方式或者是個體的學習方法上,所以如何挑選合適的演算法就成為我們應用代理人基計算建模時首要面臨的課題。 本文挑選了兩個常出現於文獻當中但是卻甚少一起比較的演算法,分別是遺傳演算法(genetic algorithms)與強化學習(reinforcement learning)。我們透過將演算法與學習理論(learning theory)結合的方式,歸納出這兩個高使用頻率的演算法各自有其適合描述的個體行為以及議題,最後並套用到代理人基彩券市場當中,而模擬的結果也證實符合真實彩券市場上多數人學習特性(個人式學習)的強化學習比起遺傳演算法更能完整地捕捉彩券市場上的特性。

從傳統化工產業進入電子特用化學品的4C行銷競爭策略分析¬-以D公司為例 / Strategic Marketing Analysis for the Electronic Chemical Business-The Case of D company

王興嘉 Unknown Date (has links)
電子產業為台灣主流產業,相關化學品使用量很大,過去多仰賴國外進口,是台灣傳統化學化工產業可用以轉型並切入的利基點。但台灣電子產業製造廠對本土化學材料供應商卻信心不足,有時根本連上線測試的機會都沒有。D公司是作者曾經任職的電子化學材料公司,也是A光電公司(LCD面板製造商)與E化學公司合資的公司,A公司的策略考量為掌握面板的上游原物料,E公司之策略則為穩定下游產品出海口。A光電公司知道要做什麼樣的產品,E化學公司則在過去累積了許多特用化學品的專業知識,所以D公司事實上是所謂know-what and know-how的結合,是電子化學材料公司轉型成功的一個案例。 本研究為導入邱志聖(2014)的4C架構,並分析D公司如何以產業的後進者,卻能克服日本競爭者的先行者優勢,而成功的關鍵點,並以此作為後續其他進入此領域或相類似產業公司的參考。藉由D公司與此產業主要競爭對手日本化學材料公司的4C比較分析可以看出,外顯單位效益成本涵蓋範圍廣,大家各有勝負,很難點出問題的核心及思考解決的策略;又日本化學材料公司的道德危機成本低於D公司,很難立即改變;但D公司的資訊交易成本比日本競爭者低(因為客戶A公司是同集團公司)。這也許是一個很好的切入點,所以D材料公司的行銷策略方向與順序為先利用降低交易成本的方式(與客戶建立合資公司),進而提升技術與成本降低等外顯單位效益成本的競爭力,並藉著產品導入的機會與實績,逐漸提升與建立聲譽(降低道德危機成本),再利用時機點的掌握與對手的可能犯錯,有策略的解決及導入有高替換成本的產品,最後再以此更強化道德危機成本。 本研究案例可提供傳統化工公司轉型之行銷策略參考,亦可適用於其他行銷門檻較高的產業。 / The electronic industry is one of the major industries in Taiwan. The chemicals consumption in this industry are huge and most imported from abroad. This could be the right industry or relative new area that the traditional chemical company in Taiwan can transform to. “D” company is a joint venture of “A” optoelectronic company (LCD panel maker) and “E” chemical company. “A” company knows the electronic products and technology trend, while “E” chemical has experience and professional knowhow in specialty chemical domain. “D” company possesses the knowledge of “know-what” and “know-how”, and is a successful chemical company in electronic industry. This study introduced the “4C Framework of Strategic Marketing Analysis” (Chiou 2014) and analyzed the key points that how the “D” company can succeed as a latecomer in the electronic chemical industry. By means of 4C analysis, it is clear to identify that the C2 (cost of information search) in “D” company is much lower than competitors due to belonging to the same group with major customer. By this, “D” company has the platform and advantages to further reduce the cost of utilities, such as technology learning curve and cost structure. By successfully introducing the products to customer one by one and build-up the credibility and reputation step by step, this can reduce the cost of moral hazard. However, the cost of asset specific is difficult to overcome. Sometime it needs to wait for the opportunity and/or the mistakes made by the competitors. With the overcome of cost of asset specific can bring more credit and reputation to further reduce the cost of moral hazard. This case study can be applied as the reference of strategic marketing analysis for transformation of traditional chemical company to electronic chemical company. It is also suitable in the area with high marketing barrier.

血壓胺在記憶上所扮演的角色

陳美如, CHEN, MEI-RU Unknown Date (has links)
一、研究動機與目的 本研究的目的,在於探討血壓胺在記憶上是扮演抑制或促進的角色,由於腦中的血壓 胺有百分之八十以上含量分佈在背縫核(B 7)和腹縫核(B 8),而投射到前腦, 背縫核大部份投射到紋狀體,腹縫核大部份投射到海馬迴,兩者在功能上有很多不一 樣的地方。因此,本實驗目的,在於分別破壞紋狀體、海馬迴和前腦中血壓胺的含量 ,來探討血壓胺在記憶上所扮演的角色。 二、研究方法 (一)實驗動物 實驗動物為90隻雄性大白鼠。 (二)實驗程序 首先分成三個實驗進行,分別手術前腦、紋狀體、海馬迴三個區域。手術十天後,開 始進行實驗,分別給予電擊訓練後,馬上注射藥物至手術的區域,以破壞血壓胺的含 量,四十八小時後,測試大白鼠對於電擊的記憶,測試完畢之後,馬上將大白鼠犧牲 掉,分別取前腦、紋狀體、海馬迴、背縮核以及腹縫核的組織,以作組織化學分析。 (三)統計分析 (1)有關記憶的行為反應,以無母數統計方法進行分析。 (2)有關腦部血壓胺含量的分析,以單因子變異量的模式進行分析。 (四)預期實驗結果 (1)行為分析 破壞血壓胺組的大白鼠,其記憶行為反應較未破壞組的大白鼠差。 (2)組織化學分析 血壓胺的含量:背縫核較腹縫核多。未被破壞組較破壞組多。
