A Bite of Computational Art

Convolutional and Neural Art

This blog post depicts my personal experience in playing with the computational art, or to be more precise, algorithms that populate pictures with elements of aesthetics. It really is great fun ...

The Monty Hall Problem: A Bayesian Approach

How I Attacked a Probabilistic Puzzle

1. How I Came Across Monty Hall It is actually pretty straightforward: a similar problem showed up in Problem Set 1 of the course Introduction to Data Mining. It all came as follows: There are...

Pretend to Be 「Aussie」 - Part Four

张老师的土澳游记

上接 Part Three 仍然多图 5.1 悉尼城市掠影 搭乘最早的一程航班，就飞向了澳大利亚之行的最后一站——悉尼。 对悉尼的第一印象就是那被大洋分成两侧的城市。从空中俯瞰悉市，确实比墨村和黄金村多了许多灵性。远处蛋壳状的悉尼歌剧院与横跨大洋两侧的海港大桥相得益彰，弧形的邦迪海滩虽然远逊色于黄金村绵长的海岸线，但点点白帆装饰的 Circular Quay 确实要迷人不少。 ...

Pretend to Be 「Aussie」 - Part Three

张老师的土澳游记

上接 Part Two 多图杀猫 4.1 Start as a Helper Gold Coast 的机场相较于 Melbourne 差别还是很大的，大概也就是一个小小的候机室，再加上一个小型的跑道。 初见 Cathy 和 Rob 才发现，他们都是很善良的人， Rob 虽然留着大胡子，但是对我们都很友善。在回程的途中，我们还接上了另一个 helper，来自中国的 Sun。 Su...

Pretend to Be 「Aussie」 - Part Two

张老师的土澳游记

上接 Part One 多图预警 3.1 初到墨村的歪果仁 忘掉飞机上吃的毫无规律的食品和身边一个比我还有精力，一心水《神医喜来乐》的老先生，独自一个人的旅行，就这么突然开始了。落了地才知道，并不是所有人的英语都跟空乘人员一样那么好听，努力去分辨他们说的每一个词实在是一件很难的事。 墨村的夏天很奇怪，冷的时候居然能到13~16度，只有在太阳下直射才会感到墨村夏天太阳公公的威力—...

Pretend to Be 「Aussie」 - Part One

张老师的土澳游记

在澳大利亚撒野的那段时光已经过去很久了，似乎已经久到大概忘记了自己为什么这么想去这么一片神秘的土地。大概想起来，或许是因为「张老板」跟我说起过她的那段在土澳做 Helper 的奇特的经历，有趣的故事，还有善良的房东；又或者是因为柳青捷足先登，自己多少有点不甘；抑或者是渴望一段所谓的 volunteer overseas 的经历吧。所以整理整理签证申请材料，打点打点行装，就踏上了一个人去...

Excuse Me, Is Anyone Here?

"Hello World, Hello Blog"

“Yep, the blog is on.” Hello 折腾了老半天， 我的博客还是开通了。 博客这个东西兴起的时候貌似我还是个小学生，据说那个时候新浪微博吵得火热。这几年来，社交媒体变迁太迅速，大家老早就放弃博客这种东西，转向新兴的微博和微信了。或者是因为现代人时间都比较零碎吧，大家再也没那么多闲心写长文章，也没闲功夫看长文章了，因此微博微信这样的快餐式阅读消费就愈发受到人...
