【每天读一点英文:生而为赢Born to Win英文经典短文】gnuhpc注释版: Companionship of Books(节选)

书籍不仅是知识的宝库,更是人们的精神伴侣。无论是在逆境中寻求慰藉还是在成长道路上寻找指引,好书总是以最耐心、最友善的方式陪伴着我们。它们跨越时间和空间,将作者的思想与读者的灵魂紧密相连。

A man may usually be known by the books he reads as well as by the company he keeps; for there is a companionship of books as well as of men; and one should always live in the best company, whether it be of books or of men.

 

A good book may be among the best of friends. It is the same today that it always was, and it will never change. It is the most patient and cheerful of companions. It does not turn its back upon us in times of adversity( [ad·ver·si·ty || əd'vɜːsətɪ]n.  逆境; 窘境; 厄运; 灾祸; 不幸) or distress[dis·tress || dɪ'stres]n.  悲痛; 不幸; 穷困). It always receives us with the same kindness; amusing and instructing us in youth, and comforting and consoling(安慰, 慰问, 抚慰) us in age.

 

Men often discover their affinity to each other by the mutual love they have for a book just as two persons sometimes discover a friend by the admiration which both entertain for a third. There is an old proverb, ‘Love me, love my dog.” But there is more wisdom in this:” Love me, love my book.” The book is a truer and higher bond of union. Men can think, feel, and sympathize with each other through their favorite author. They live in him together, and he in them.

 

A good book is often the best urn( [ɜrn /ɜːn]n.  瓮, 骨灰瓮, 缸) of a life enshrining( [en·shrine || ɪn'ʃraɪn]

v.  入庙祀奉; 铭记) the best that life could think out; for the world of a man’s life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which, remembered and cherished, become our constant companions and comforters.

 

Books possess an essence([es·sence || 'esns]n.  基本, 原素, 本质) of immortality. They are by far the most lasting products of human effort. Temples and statues decay, but books survive. Time is of no account with great thoughts, which are as fresh today as when they first passed through their author’s minds, ages ago. What was then said and thought still speaks to us as vividly as ever from the printed page. The only effect of time have been to sift out (淘汰)the bad products; for nothing in literature can long survive e but what is really good.

 

Books introduce us into the best society; they bring us into the presence of the greatest minds that have ever lived. We hear what they said and did; we see the as if they were really alive; we sympathize with them, enjoy with them, grieve with them; their experience becomes ours, and we feel as if we were in a measure actors with them in the scenes which they describe.

 

The great and good do not die, even in this world. Embalmed(使不被遗忘) in books, their spirits walk abroad(广泛传播). The book is a living voice. It is an intellect to which on still listens.

根据原作 https://pan.quark.cn/s/459657bcfd45 的源码改编 Classic-ML-Methods-Algo 引言 建立这个项目,是为了梳理和总结传统机器学习(Machine Learning)方法(methods)或者算法(algo),和各位同仁相互学习交流. 现在的深度学习本质上来自于传统的神经网络模型,很大程度上是传统机器学习的延续,同时也在不少时候需要结合传统方法来实现. 任何机器学习方法基本的流程结构都是通用的;使用的评价方法也基本通用;使用的一些数学知识也是通用的. 本文在梳理传统机器学习方法算法的同时也会顺便补充这些流程,数学上的知识以供参考. 机器学习 机器学习是人工智能(Artificial Intelligence)的一个分支,也是实现人工智能最重要的手段.区别于传统的基于规则(rule-based)的算法,机器学习可以从数据中获取知识,从而实现规定的任务[Ian Goodfellow and Yoshua Bengio and Aaron Courville的Deep Learning].这些知识可以分为四种: 总结(summarization) 预测(prediction) 估计(estimation) 假想验证(hypothesis testing) 机器学习主要关心的是预测[Varian在Big Data : New Tricks for Econometrics],预测的可以是连续性的输出变量,分类,聚类或者物品之间的有趣关联. 机器学习分类 根据数据配置(setting,是否有标签,可以是连续的也可以是离散的)和任务目标,我们可以将机器学习方法分为四种: 无监督(unsupervised) 训练数据没有给定...
