Machine learning Algorithm

1. Introducing   Recommendation engine

Everyday we form opinions about things we like, don’t like and even don’t care about. For example, when you watch a television show, you either notice it because it’s a funny show, or because it is boring or maybe don’t notice it at all. It happens without we noticing and with food, movies, songs, hairstyles, ski resorts and so on.
Our tastes vary, but we generally follow patterns. People tend to like things that are similar to other things they like. Because I love the Matrix film, you can guess I would like to watch Minority Report, which is mostly the same genre, action and sci-fi. Likewise, people also tend to like things that similar people like. Just consider a design student that entered the design school, when he sees just every other design student using a Macintosh computer, he isn’t surprised, since he was already a lifetime Mac user. Recommendation is all about predicting these likes and dislikes, and using them to discover new and desirable things you didn’t already know about.

1.1 What is recommendation ?

In this tutorial, we will explore some of the ways people make recommendations and discover new things – and of course learn how those systems work in software with Crab. There are several strategies for creating recommendations: One could look to what people with similar tastes seem to like. Another approach would figure out what items are like the ones we already like. Those strategies describe the two most well-known categories of recommender techniques: user-based anditem-based recommenders and they are included in a major category called Collaborative Filtering. Before exploring them, let’s explain the differences between this type of filtering and the Content-Based Filtering, another popular large recommendation category.

1.2. Collaborative Filtering and Content-Based Filtering

The scenarios above presented are examples of Collaborative Filtering, which produces recommendations based on the knowledge of users’ relationships to items. In this category there is no requirement for knowledge of the properties or attributes of the items themselves. This recommender framework does not care whether the items are books, movies, flowers, or even people, since nothing about their attributes enters into any of the input.
Approaches focusing on the attributes of items are usually referred to as content-based filtering recommendation techniques. For instance, consider a book recommender system, which recommends you Programming the Collective Intelligence because you love Artificial Intelligence books (you already read several books about A.I. and the system knows your historical records). It is clear that the recommendation is based on an attribute of the books: the main category. This is something more like content-based recommendation.

Why php6 is more effective than all version of php..?

There are few reasons frds..


This equates to PHP having to store both Unicode and non-Unicode variants of class,
method and function names in the symbol tables.
In short - it uses up more resources.

2. Register Golbal to go

This means that php6 will finally break all PHP3 era scripts (or any script using reg globals)
with no recourse at all but to re-code it.

3. Safe mode to go

    php6 is most useful to use in safemode working than others. and found  E_CORE_ERROR.and make
    php  secure.

4.Fast CGI always on.
   The FastCGI code will be cleaned up and always enabled for the CGI SAPI,
    it will not be able to be disabled.

5.Register long array to go

Now the HTTP__VARS  not globals.  Well if you're not already using $_GET, $_POST, etc -
start doing so now, because the option to enable long arrays is going
(and will throw an E_CORE_ERROR).

6. Extension Movements
   The XMLReader and XMLWriter extensions will move into the core distribution and
will be on by default.

7.PHP Engine Additional.

  It can add some additional funactionality in php6.

Creating an iPhone Application its  very easy just follow steps.

Step One - Create a New iPhone Project

Step Two - Create a View for the Application 

Step Three - Adding Elements to the View


  Step Four - Implementing the View in Your Application.

And the code is ....

#import <UIKit/UIKit.h> @class HelloWorldViewController; @interface HelloWorldAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; HelloWorldViewController *hwvc; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) HelloWorldViewController *hwvc;   The final output looks like ..

iPhone 5 to Have 4-inch Screen, Report Claims

Well, it looks like Apple isn't going to go smaller without going a little bigger, too. We just heard that Apple's working on a smaller iPhone (an iPhone "nano," if you will), and now new reports suggest Apple's working on an iPhone with a larger display.

Reports by Taiwanese trade paper DigiTimes claim that Apple is expanding the regular iPhone's screen to 4 inches. According to DigiTimes, Apple is planning a 4-inch screen for its iPhone 5 in order to "compete with the Google Android platform in the 4- to 7-inch smartphone market."

This is noteworthy, of course, because it's been suggested that Apple's rumored mini-iPhone is Apple's answer to Google's mobile OS. So which is it? Does Apple need a smaller phone or a larger phone to compete with Android? Maybe both and maybe a third option to boot.

DigiTimes cites unnamed "component suppliers," who have "noted that the production lines for Apple's next generation iPhone have begun testing, and Apple is interesting [sic] in expanding the screen size to 4-inches to support the tablet PC market as the vendor only has a 9.7-inch iPad in the market."

Sure, that makes sense...although, last I checked, Apple basically owned the tablet PC market (although the iPad recently dropped to a meager 75 percent of the market share).

I, for one, would love a 4-inch iPhone screen (I often pull out my Droid X to read Websites...both for the screen size, and the network--sorry AT&T), but these are just rumors. In case you're wondering, the iPhone 4 has a 3.5-inch screen.

Speaking of rumors, a Taiwanese blog,, says there are three iPhone 5 prototypes currently being tested--one with a sliding cover, one with a sliding keyboard, and one that looks a lot like the iPhone 4.
