How To Get Fast Retrieval Of Data

A crucial task in many recommender problems like computational advertising, content optimization, and others is to retrieve a small set of items by scoring a large item inventory through some elaborate statistical/machine-learned model. This is challenging since the retrieval has to be fast (few milliseconds) to load the page quickly. Fast retrieval is well studied in the information retrieval (IR) literature, especially in the context of document retrieval for queries. When queries and documents have sparse representation and relevance is measured through cosine similarity (or some variant thereof), one could build highly efficient retrieval algorithms that scale gracefully to increasing item inventory. The key components exploited by such algorithms is sparse query-document representation and the special form of the relevance function. Many machine-learned models used in modern recommender problems do not satisfy these properties and since brute force evaluation is not an option with large item inventory, heuristics that filter out some items are often employed to reduce model computations at runtime.

There are a two-stage approach where the first stage retrieves top-K items using our approximate procedures and the second stage selects the desired top-k using brute force model evaluation on the K retrieved items. The main idea of our approach is to reduce the first stage to a standard IR problem, where each item is represented by a sparse feature vector (a.k.a. the vector-space representation) and the query-item relevance score is given by vector dot product. The sparse item representation is learn to closely approximate the original machine-learned score by using retrospective data. Such a reduction allows leveraging extensive work in IR that resulted in highly efficient retrieval systems. Our approach is model-agnostic, relying only on data generated from the machine-learned model. We obtain significant improvements in the computational cost vs. accuracy tradeoff compared to several baselines in our empirical evaluation on both synthetic models and on a (CTR) model used in online advertising.

Fast Retrieval of View Data Using the ViewNavigator Cache - V8.52
Beginning with the R8.52 release of Notes/Domino there is a clear performance winner in the race to enumerate data from a View using the Backend View related classes. Significant performance work has been done on the ViewNavigator class to allow it perform well enough to serve as the underpinnings for XPage screen display. You can gain the benefits of these enhancements for your application whether it is written in Java, LotusScript, or JavaScript.

The Backend ViewNavigator cache reduces the number of server transactions and associated network overhead when navigating and reading Column Values information from the Documents and Entries in a View. Performance gains are most profound when accessing a View residing on a server from a client, however retrieval from local Views will also be greatly improved.

Internet addiction on society

           The study explored the immediate impact of internet exposure on the mood and psychological states of internet addicts and low internet-users. Participants were given a battery of psychological tests to explore levels of internet addiction, mood, anxiety, depression, schizotypy, and autism traits. They were then given exposure to the internet for 15 min, and re-tested for mood and current anxiety. Internet addiction was associated with long-standing depression, impulsive non-conformity, and autism traits. High internet-users also showed a pronounced decrease in mood following internet use compared to the low internet-users. The immediate negative impact of exposure to the internet on the mood of internet addicts may contribute to increased usage by those individuals attempting to reduce their low mood by re-engaging rapidly in internet use.

        Over the past decade, since the term became widely debated in the medical literature, ‘internet addiction’ has become regarded as a novel psychopathology that may well impact on a large number of individuals. The focus of internet use in ‘internet addicts’ is varied, but using the internet for gambling and pornography are common amongst such individuals. The negative impact of excessive internet use can be seen across a wide range of aspects of the persons’ life.There has been a big percentage of people spending their time on the internet rather than spending time with their family, or friends. Internet use has been categorized as an actual disorder, and has been termed 'Internet Addiction' because of its similarity to addictions like smoking, drinking, and watching too much TV. 

Keep it under control

      Limit your time online: Chrome users can install plug-ins like StayFocusd while Firefox users can opt for LeechBlock. Decide on a certain amount of time, or certain time period which you want to stay off the sites you can’t seem to get enough of. When you fire up your browser, and see the block, it will serve as a good reminder that there are better ways you could be spending your spare time.

      If you have other gadgets that get you online – such as a phone or a tablet, simply switch off your push notifications, and even switch off your Internet connection. Kill the data connection on your phone. Turn off your router, and go do something else. Mac and Windows users can use an app like Freedom to switch off your Internet connection for up to 8 hours at a time. If you need the Internet for work, at least switch off notifications that tend to distract you.

Evolution is an intangible asset that supports constant improvement

Of course this imperative theory applies to the World Wide Web too. Creating a fully functional and an effective website is an essential combination of skill, technology and lastly, accessibility. We have been riding high on the first two parameters for about a decade now, but a website still seems incompetent when it lags behind in terms of accessibility. A website is said to be accessible when it serves its need to all users, irrespective of their conditions, limitations or available technology. Underestimating the concept of accessibility not only leads to loss of visitors but demeans your business goal too. We present this compilation to my readers to make them understand the long lost importance of accessibility and ways to achieve it.

There are chances that a very notable percentage of your target customers lag behind in terms of technology and physical ability, which is why your website may not be able to serve them in a better way compared to the normal ones. Targeting these underprivileged categories can offer a boost to website traffic and profit too.   

Website is a universal phenomenon with a primary aim to disseminate information to the masses irrespective of any geographical boundary. In short, a website is universal in nature, which is why it has to be accessible to a varied kind of audiences. 

Cross Browser Compatibility: Cross browser compatibility, it means the website has to look the same in all the prevalent web browsers. By prevalent browsers I mean names like Internet Explorer, Google Chrome, Mozilla Firefox, Opera and many more.

Some good tools for good web designing for Cross Browser Compatibility:

Firebug: A brilliant tool that effectively analyzes specific issues with CSS styles and HTML Entities. Plus, Firebug is an essential Firefox add-on, which again benefits a lot to the designers and developers while working on cross browser compatibility. Similarly, we have Firebug Lite that is implemented to bring-in Firebug visual interface and debugging functions to web browsers. This tool is deployed as a client side JavaScript code and is very easy to include in the WebPages.  

CSS3Pie: The tool allows you to include drop shadows and rounded corners along with the CSS, which will enable the website to work well with all major browsers. This essential tool frees you from the burden of moving across multiple div’s, images and gradients.  

IE Tester: As we mentioned earlier, Internet Explorer is one of the most used browsers that we have today, which makes this tool even more important. What makes dealing with IE tricky is that only a single version is installed on any Windows PC at a time. Developers used to deal with this issue by setting multiple virtual PCs; however, with the help of IE Tester you test the website on a single browser. Using a single browser, a developer will be able to use different tabs from each version.
