Convolutional Neural Network(CNN)は、ディープニューラルネットワークを用いた画像分類器である.しかし,CNNは分類したクラスに対する判断根拠を提示することができないという欠点をもつ.この問題を解決するため,判断根拠となる画像の一部を提示する可視化手法が提案されている. 分類に対する判断根拠の可視化と同様に,学習過程の視覚化も重要だと考えている. CNNのクラス判別性能はパラメータの影響が大きい事が知られている.そのため,学習過程の視覚化が可能となる事によりパラメータ調整を効率的に行うことができる. そこで我々は学習過程を視覚化する方法を提案する.提案手法はCNNの学習過程におけるエポック毎に,任意のクラスの分類判断根拠画像を生成する.提案手法の有効性を検証するため,MNISTデータセットを用いた。その結果、提案手法が,従来手法では不可能であった任意のクラスに対する学習過程を視覚化できることを示した.

On August 8, 2016, the “Emperor's Statement Regarding His Majesty's Duty as the Symbol of the State”(henceforth, “The Statement”) was presented to the public. In 2017 the Japanese Diet enacted a special law (henceforth, “Special law”) that provided a legal exception to the Imperial Houshold Law, which allowed the abdication of the sitting Emperor at that time. At the end of April 2019, the now Emperor Emeritus abdicated the Chrysanthemum Throne, and on the next day, the current Emperor made His Majesty’s Accession. Just after “The Statement” was presented, a question was raised regarding whether such a Statement could be seen as giving rise to a conflict with the clause of the Constitution of Japan stating that “The Emperor…shall not have power related to government” (Art.4, Cl.1). During an interview by Asahi Shimbun I previously stated that “The Statement” needs not be deemed unconstitutional. I, however, suggested, that the reason why “The Statement” is not unconstitutional is, in fact, not so simple to answer and made clear that providing such reasoning would require a more precise, in-depth legal analysis. This article is the result of my theoretical research into the reason, why “The Statement” need not be deemed unconstitutional. It can not be denied that there was causal relationship between “The Statement” and the enactment of the special law regarding the Emperors abdication―causal in the sense, that if “The Statement” was not presented, the Special Law would not have been timely enacted to allow the Emperor Emeritus's abdication. On the other hand, recognition needs to be made that the contents of “The Statement”―itself, does not include any direct political appeal to the People. Instead, “The Statement” provided objective explanations regarding, among others, the following points: how His Majesty embraced the role as the “Symbol of the State” under the Constitution of Japan; and the anticipated future difficulties in fulfilling the Emperor's duties because of His Majesty’s advanced age. To this end, we can therefore say that―by presenting these explanations―the Emperor Emeritus actually fulfilled His Majesty’s responsibility as the “Symbol of the State”. Perhaps there may have been some levels of “guessing” by the People regarding the Emperor Emeritus's Inner Thoughts” and His Majesty's wishes to abdicate. But, especially in the case of Emperor Emeritus, what can not be said is that the abdication was realized via the Emperor's “authority” or the difference in the relative positioning of the Emperor to the People. And, on that note, we find that even the manner in which “The Statement” was presented did not create a conflict with the constitutional law.

本発表では、京都のスナックでの記録した会話の分析をもとに、ママと客との間に見られるやりとりを考察する。とくに怒りやそれに類似する感情や「叱りつける」という行為を扱う。スナックは、ママが主に男性客に飲食物を提供する場所である。こうした場所で客を叱りつけて、その面子をつぶすということは通常考えられない。あってもきわめて計算されている。そこにはまた性的関係を回避する「脱性化」の機能も認められる。

With which crime should be charged, for example, against the parents who have caused the death of their child through negligence? As a regulation related to this act, the following is considered. First, in Japanese criminal law, Article 218 (Abandonment by the Person Who Is Responsible for Protection) provides that "when a person who is responsible for protection of the immature..., fails to give necessary protection to such person, the person shall be punished..." Moreover, when the victim suffered death or injury, abandonment causing death or injury (Article 219) is charged against the person. On the other hand, Article 199 (Homicide) provides that "a person who kills another shall be punished...", and, according to a prevailing view, is applied murder by omission. In the above-mentioned case, there are the precedents judged either as homicide or as abandonment against the acts causing death by neglecting the victims. Then, what is the standard to classify these 2 crimes? This study is to provide perspective view to the standard through a consideration of the related precedents.

Focusing on two classes of as well as their teachers of three-year-old children as well as their teachers in a kindergarten, this research, which was held between April to October 2005, investigates how gender consciousness among children are related to their social relationships with teachers are peer groups. The research finds out that a majority of the children did not have any gender identity before entering the kindergarten, and there is no clear evidence to show that sex or date of birth are related to the time when children identity their gender. However, before entering the summer vacation at July, most of the children already have clear gender consciousness. The research then shows that children will recognize their gender identity earlier if they prefer playing within a group and communicating more with teachers. On the contrary, for those children who prefer to play alone or to keep a distance from teachers, they will identity their gender later. In addition, for those children who always stick to teacher but prefer to play alone, they still have earlier gender consciousness.

越後平野周辺の旧石器時代および縄文時代の遺跡について,沖積低地の様相を中心に,当時の地形や環境を考慮しながら,立地とその変遷を検討した.越後平野周辺の丘陵を含む全域的な分布と,さらに海岸部を対象にした分布をまとめることによって,遺跡立地と変遷の状況を具体的に明らかにした.その結果,沖積低地への進出の画期は縄文時代前期に求められ,縄文時代後・晩期には分布域が沖積地側に移行する傾向をとらえることができた.また,沖積低地において,縄文時代前期以前の古い遺跡が空白に近い分布を示すことについて,それらの遺跡が越後平野に厚く堆積する沖積層中に埋没している可能性を指摘した.

膠着言語である日本語は単語境界が自明でないため、さまざまなアプリケーションで文章を取り扱う際に、「単語」単位の操作が英語ほどには簡単でなかった。単語の選択・置換・検索といった基本的な操作を可能にし、また更に深い自然言語解析の第一歩とするために、われわれは極めてコンパクトな形態素解析コンポーネント、愛称"T-Hammer"を研究開発した。本稿では、共通コンポーネントとしての T-Hammerの概要、精度、および今後の課題について考察する。現在 T-HammerはWord 97, Encarta, Bookshelf, IISなどの製品に実装されている。

In the United States and Europe, percutaneous edge-to-edge repair of the mitral valve with the MitraClip device for patients with severe degenerative mitral regurgitation who are at prohibitive surgical risk has been well-established. Recent randomized controlled trials have also demonstrated significant clinical benefits with the use of the device in selected patients with functional mitral regurgitation. Thus far, >80,000 patients in more than 50 countries have undergone the MitraClip procedure. Despite the exponential growth worldwide, the rate of MitraClip adoption in Asia has been more gradual. In addition, very few publications describe the use of MitraClip in Asian populations. This review aims to describe the Asian experience with the MitraClip device and the challenges faced.
