一些重要的算法 - 0 views

  • 下面是一些比较重要的算法,原文罗列了32个,但我觉得有很多是数论里的,和计算机的不相干,所以没有选取。下面的这些,有的我们经常在用,有的基本不用。有的很常见,有的很偏。不过了解一下也是好事。也欢迎你留下你觉得有意义的算法。(注:本篇文章并非翻译,其中的算法描述大部份摘自Wikipedia,因为维基百科描述的很专业了)
  • A*搜寻算法俗称A星算法。这是一种在图形平面上,有多个节点的路径,求出最低通过成本的算法。常用于游戏中的NPC的移动计算,或线上游戏的BOT的移动计算上。该算法像Dijkstra算法一样,可以找到一条最短路径;也像BFS一样,进行启发式的搜索。 Beam Search束搜索(beam search)方法是解决优化问题的一种启发式方法,它是在分枝定界方法基础上发展起来的,它使用启发式方法估计k个最好的路径,仅从这k个路径出发向下搜索,即每一层只有满意的结点会被保留,其它的结点则被永久抛弃,从而比分枝定界法能大大节省运行时间。束搜索于20 世纪70年代中期首先被应用于人工智能领域,1976 年Lowerre在其称为HARPY的语音识别系统中第一次使用了束搜索方法,他的目标是并行地搜索几个潜在的最优决策路径以减少回溯,并快速地获得一个解。 二分取中查找算法一种在有序数组中查找某一特定元素的搜索算法。搜素过程从数组的中间元素开始,如果中间元素正好是要查找的元素,则搜素过程结束;如果某一特定元素大于或者小于中间元素,则在数组大于或小于中间元素的那一半中查找,而且跟开始一样从中间元素开始比较。这种搜索算法每一次比较都使搜索范围缩小一半。 Branch and bound分支定界(branch and bound)算法是一种在问题的解空间树上搜索问题的解的方法。但与回溯算法不同,分支定界算法采用广度优先或最小耗费优先的方法搜索解空间树,并且,在分支定界算法中,每一个活结点只有一次机会成为扩展结点。 数据压缩数据压缩是通过减少计算机中所存储数据或者通信传播中数据的冗余度,达到增大数据密度,最终使数据的存储空间减少的技术。数据压缩在文件存储和分布式系统领域有着十分广泛的应用。数据压缩也代表着尺寸媒介容量的增大和网络带宽的扩展。 Diffie–Hellman密钥协商Diffie–Hellman key exchange,简称“D–H”,是一种安全协议。它可以让双方在完全没有对方任何预先信息的条件下通过不安全信道建立起一个密钥。这个密钥可以在后续的通讯中作为对称密钥来加密通讯内容。 Dijkstra’s 算法迪科斯彻算法(Dijkstra)是由荷兰计算机科学家艾兹格·迪科斯彻(Edsger Wybe Dijkstra)发明的。算法解决的是有向图中单个源点到其他顶点的最短路径问题。举例来说,如果图中的顶点表示城市,而边上的权重表示著城市间开车行经的距离,迪科斯彻算法可以用来找到两个城市之间的最短路径。 动态规划动态规划是一种在数学和计算机科学中使用的,用于求解包含重叠子问题的最优化问题的方法。其基本思想是,将原问题分解为相似的子问题,在求解的过程中通过子问题的解求出原问题的解。动态规划的思想是多种算法的基础,被广泛应用于计算机科学和工程领域。比较著名的应用实例有:求解最短路径问题,背包问题,项目管理,网络流优化等。这里也有一篇文章说得比较详细。 欧几里得算法在数学中,辗转相除法,又称欧几里得算法,是求最大公约数的算法。辗转相除法首次出现于欧几里得的《几何原本》(第VII卷,命题i和ii)中,而在中国则可以追溯至东汉出现的《九章算术》。 最大期望(EM)算法在统计计算中,最大期望(EM)算法是在概率(probabilistic)模型中寻找参数最大似然估计的算法,其中概率模型依赖于无法观测的隐藏变量(Latent Variable)。最大期望经常用在机器学习和计算机视觉的数据聚类(Data Clustering)领域。最大期望算法经过两个步骤交替进行计算,第一步是计算期望(E),利用对隐藏变量的现有估计值,计算其最大似然估计值;第二步是最大化(M),最大化在 E 步上求得的最大似然值来计算参数的值。M 步上找到的参数估计值被用于下一个 E 步计算中,这个过程不断交替进行。
  • 快速傅里叶变换(FFT)快速傅里叶变换(Fast Fourier Transform,FFT),是离散傅里叶变换的快速算法,也可用于计算离散傅里叶变换的逆变换。快速傅里叶变换有广泛的应用,如数字信号处理、计算大整数乘法、求解偏微分方程等等。本条目只描述各种快速算法,对于离散傅里叶变换的性质和应用,请参见离散傅里叶变换。 哈希函数HashFunction是一种从任何一种数据中创建小的数字“指纹”的方法。该函数将数据打乱混合,重新创建一个叫做散列值的指纹。散列值通常用来代表一个短的随机字母和数字组成的字符串。好的散列函数在输入域中很少出现散列冲突。在散列表和数据处理中,不抑制冲突来区别数据,会使得数据库记录更难找到。 堆排序Heapsort是指利用堆积树(堆)这种数据结构所设计的一种排序算法。堆积树是一个近似完全二叉树的结构,并同时满足堆积属性:即子结点的键值或索引总是小于(或者大于)它的父结点。 归并排序Merge sort是建立在归并操作上的一种有效的排序算法。该算法是采用分治法(Divide and Conquer)的一个非常典型的应用。 RANSAC 算法RANSAC 是”RANdom SAmpleConsensus”的缩写。该算法是用于从一组观测数据中估计数学模型参数的迭代方法,由Fischler and Bolles在1981提出,它是一种非确定性算法,因为它只能以一定的概率得到合理的结果,随着迭代次数的增加,这种概率是增加的。该算法的基本假设是观测数据集中存在”inliers”(那些对模型参数估计起到支持作用的点)和”outliers”(不符合模型的点),并且这组观测数据受到噪声影响。RANSAC 假设给定一组”inliers”数据就能够得到最优的符合这组点的模型。 RSA加密演算法这是一个公钥加密算法,也是世界上第一个适合用来做签名的算法。今天的RSA已经专利失效,其被广泛地用于电子商务加密,大家都相信,只要密钥足够长,这个算法就会是安全的 并查集Union-find并查集是一种树型的数据结构,用于处理一些不相交集合(Disjoint Sets)的合并及查询问题。常常在使用中以森林来表示。 Viterbi algorithm寻找最可能的隐藏状态序列(Finding most probable sequence of hidden states)   附录 关于这个世界上的算法,你可以看看Wikipedia的这个网页:http://en.wikipedia.org/wiki/List_of_algorithms 关于排序算法,你可以看看本站的这几篇文章《一个显示排序过程的Python脚本》、《一个排序算法比较的网站》

Why the Future of Home Page Design is "Funnel Marketing" - 0 views

  • I want to ask you a question that is the driving point to this entire article: As a consumer, when you land on the home page of a website, what do you want to achieve? In other words, what’s your immediate goal? Really, think about this question for a second before continuing. What is it that makes a great home page vs. one that frustrates you and leaves you wanting? Although many answers could be given to this question, I submit we all share one central desire: To find what we’re looking for IMMEDIATELY…without having to think too hard to get it. It used to be, and still is for many companies, that a website’s home page was loaded with text—stuffed with every keyword possible and enough messaging to practically write a book. In fact, as I’ve worked with dozens of clients over this past year with their web marketing strategies, one of the most common problems is cluttered and confusing home page design. But in 2012 and beyond, the principle of “Less is More” has never been stronger when it comes to effective web design and lead generation as “funnel marketing” (as I like to call it) appears to be the choice for many of the industry’s leading conversion authorities. Let’s look at a few examples of companies doing it right:
  • Copyblogger: With 4 distinct funnels, Copyblogger is the ultimate example of simplicity combined with efficacy. Always known for their incredible focus on design and conversions, Copyblogger’s most recent home page design manages to perfectly allow the viewer to quickly and easily choose a funnel based on their needs. Although not shown in this image, the rest of their home page continues this theme with a strong newsletter opt-in and then their latest blog article.
  • Convince and Convert: With 3 prevalent funnels showing, viewers can easily land on Jay Baer's site and find what they're looking for, or simply opt-in to his newsletter as well. I’m a huge fan of what Jay Baer recently did with his website’s homepage, as it in many ways is the ultimate “How to” example of setting up a site built to convert traffic into leads but also allow viewers to quickly find what they’re looking for. Because Jay’s two main business are speaking and consulting, they show prevalently at the top but there is also a strong call-to-action with his newsletter opt-in box at the bottom right.

  • River Pools and Spas Going from left to right, the 4 funnels take the prospect further and further down the buying funnel of a fiberglass swimming pool. Over the years, I’ve experimented again and again and again with my swimming pool company’s homepage, but as far as increased lead conversions go, my current design has proven very effective. In fact, if you look at the four main funnels, going from left to right, you can see each addresses a “stage” in which a consumer may currently find him or herself in the buying process. For example, if you’re just getting started with researching pools, you’re going to visit “Inground Pool 101.” If you’re starting to get more serious with your research but you’re still not ready to meet with someone, you’ll likely download an eBook or order our DVD. And finally, when you’ve researched enough of our products and you feel you’re ready to take things to the next level, you’ll call us for a quote. As you truly understand your buying personas as an organization, the process of knowing what funnels to offer web viewers will get easier and easier.
  • HubSpot With 3 main funnels and a touch of social proof, HubSpot shows why their database grows by the hundreds every day. Similar to Copyblogger, HubSpot demonstrates the “less is more” technique clearly on their homepage with 3 main call-to-action funnels– (A free eBook, a free webinar, or a free trial)– all of which are set up to get prospects into a buying funnel and commence one of HubSpot’s now practically famous lead-nurturing campaigns.
  • SEOmoz 4 funnels and a little social proof help SEOmoz lead their visitors perfectly down whichever funnel they choose. It’s no surprise the leading search engine optimization site on the web is also one of the leading lead-optimization sites as well. Similar in scope to the HubSpot design, SEOmoz quickly gives viewers the ability to start a free trial of their impressive software as well as learn the 3 main components of what makes the software so effective with the bottom call-to-action funnels.
  • KISS We’ve all heard the model of KISS, or Keep It Simple Stupid, but never has the phrase been more prevalent when it comes to effective home page design to generate leads, traffic, and sales. In essence, if you’re looking to enhance your company’s homepage to make things easier to navigate and also increase leads, here are some tips for review: Don’t go nuts on the amount of text. People don’t want to invest in heavy reading until they dig further into your website. Make your services pop, preferably with visible images, buttons, and calls-to-action. A little social proof is a good thing. An opt-in box where the prospect can easily subscribe to further articles/information (see Jay Baer or Copyblogger) from your company should be prominent. Your Turn: A couple of quick questions folks. Have you noticed this trend of more simple home pages combined with less text and more prevalent marketing funnels? Also, how would you describe your company’s current home page design and where do you feel it’s falling short? What have you done that has proven effective? Jump in folks, I’d love to hear your thoughts.

如何降低landing page的跳出率 - 1 views

  • 现在这个经济不景气的时候,49%的跳出率和50%的跳出率,最后的结果会相差很大:   1.一个页面要有大字标题,这个标题和在外面的宣传广告上的一致或者相近; 2.页面上要有明显引导到下一页或者希望访者操作的按钮或者链接;页面上可以增加一些如Learn More, Help Me Choose, Compare, Next Step等明显的链接,引导用户在这个页面上进行下一步的操作; 3.页面上的文字要用第二人称,告诉别人“您”能获得什么,“您”能怎么怎么,切忌说“我们”能提供什么,“我们”能怎么怎么; 4.页面上的一个产品或服务的时候,要说明这个产品或服务能解决什么问题,而不要一味的宣传这个产品或者服务有什么什么优点好处; 5.页面上不要堆砌很多内容,越简单越集中越好,一般建议是这个页面上不要加导航栏,或者链接到其他功能的链接按钮等 6.页面上的内容要和宣传的主要目的一致,Keep your body copy on point as a logical progression from your headline and offer. 7.在页面上要确保主要内容在最显眼位置并且容易被用户眼睛“扫射”到; 9.确保页面上的第一个段落简短,最好控制在两行之内;(切记这里是两行,而不是两句) 10.确保所有需要的内容在第一屏;特别是是一些引导的按钮和链接;   最后一点是一个页面策划好之后按照用户的思维测试下,可以问自己这么几个问题:  我是怎么到达这个页面的?(这个页面的宣传口号要和这个页面一致,不能“骗”用户进来)  我来这个页面做什么?(页面的目的) 我能在这个页面做什么?(一些引导按钮链接要显眼)

Weblinks: Example | High Scalability - 0 views

  • An Unorthodox Approach to Database Design : The Coming of the Shard Tue, 07/31/2007 - 18:13 — Todd Hoff Once upon a time we scaled databases by buying ever bigger, faster, and more expensive machines. While this arrangement is great for big iron profit margins, it doesn't work so well for the bank accounts of our heroic system builders who need to scale well past what they can afford to spend on giant database servers. In a extraordinary two article series, Dathan Pattishall, explains his motivation for a revolutionary new database architecture--sharding--that he began thinking about even before he worked at Friendster, and fully implemented at Flickr. Flickr now handles more than 1 billion transactions per day, responding in less then a few seconds and can scale linearly at a low cost. What is sharding and how has it come to be the answer

  • eBay Architecture Tue, 07/10/2007 - 15:40 — Todd Hoff Who hasn't wondered how eBay does their business? As one of the largest most loaded websites in the world, it can't be easy. And the subtitle of the presentation hints at how creating such a monster system requires true engineering: Striking a balance between site stability, feature velocity, performance, and cost. You may not be able to emulate how eBay scales their system, but the issues and possible solutions are worth learning
