The Gaussian Probability density function(pdf) is extensively used in pattern recognition because of its mathematical tractability as well as because of the central limit theorem. Thelatter states that the pdf of the sum of a number of statistically independent random variables tends to the Gaussian one as the number of summands tends to infinity. In practice, this is approximately true for a large enough number of summands. Often we refer to the Gaussian pdf as the normal pdf and we use the notation N(m,S). Gaussian Probability density function（PDF）は広くパターン認識に使われる。それは使い易いこともあるが、同時に中心極限定理（よく覚えてませんけど、特に分布を歪める要因がない場合各サンプルの平均値は標準分布に従ってバラけるとか、そんな感じだったかと）のせいだ。 中心極限定理は相互に依存しない（一つの値が確定することが他の値に影響を与えない）ランダム変数の総計のFDFを計算するとGaussianのそれに近づくと定義する。何故ならば、summmandsの数は、無限へと近づくからだ（無限でない場合も、ある一定以上の数のsummandsであれば、無限である場合と近似の結果が得られる）。 Gaussian PDF はnormal PDF と書かれることも多く、N(m,S). のサインが使われる。 統計は基本的なこと以外全部忘れてるんで、何言ってるか解りません。というかこのレベルのことやってるなら、自力で解読できないと後々大変ですよ。101の英語テキスト使って基本的なこと押さえとくことお勧めします。

和訳&解説お願いします。 Let X be the resulting matrix,having the feature vectors as columun. Compute the ML estimate of the mean value,m,and the covariance matrix, S, of N(m,S) and comment on the resulting estimates. It can be observed that the estimates that define the corresponding Gaussian pdf, although close to the true values of the parameters, cannot be trusted as good estimates. This is due to the fact that 50points are not enough to result in reliable estimates. Note that the returned values depend on the initalization of the random generator, so there is a slight deviation among experiments. 自分なりに単語の意味を調べて、ガウス分布に関する推定値を計算する際、おおよその値は求められるが信頼できる値ではない(50pointが信頼できる値として十分ではない)などが述べれらていることはわかったのですが、きれいな文章にできません。(特にNote tat 以降) もしよろしければどなたか和訳と訳す際のポイントを教えていただけませんか？

以下の英文の和訳をお願いします。 Nevertheless, one might speculate that deterministic way will play an increasingly important role, if only because they allow us to tap into our highly developed intuition as to the behavior of individual vortices. We do not have the same intuitive relationship to statistical theories, which in any event are plagued by the curse of the closure problem. ちなみに、 vortices：渦 closure problem：クロージャー問題 です。 英語苦手なので、よろしくお願いします。
