How Google Autocomplete works in Search

The Workings behind Google Auto complete

We all know what autocomplete is and how it works (basically) but what we don’t really know is how much time it saves for us. A post by Google shows that Google autocomplete saves around 25% of our typing time or in other words around 200 YEARS of typing time per day, Yes you read right 200 YEARS per DAY! On the other hand google autocomplete is especially useful for mobile devices as you don’t have to take too long on typing on a smaller screen. Though, most of us have become master typists at this point.

Google Autocomplete is a feature that you will find anywhere, that is wherever there is a Google search bar like obviously Google Home, Google app present in Android and iOS, Quick search box in Android and Omnibox address bar within Chrome. Type and there you have the predictions appear.

Google uses the term predictions in Google Autocomplete:

In a Google article recently posted, Google has specifically used the word predictions to describe Google autocomplete rather than suggestions and for good reason too. Google autocomplete tries to predict what you want to search for, rather than showing you what different things you can search for.
Determining of Predictions on Google Autocomplete:

Google looks at real searches done by other users, trending information and your location and passed searches to create predictions in Google’s Autocomplete. It fills in predictions according to words already typed and eliminates search predictions that do not match words as and when more info is typed by us.

Predictions against Google Autocomplete rules:

When it comes to giving predictions, Google does not want to shock users in getting out- of- context and insensitive searches so they have put up a set of rules to govern the same within Google autocomplete.

Some of the predictions that are against the rules are hateful comments against groups or individuals on the basis of race, religion etc., predictions that are violent and dangerous and harmful predictions.
Google also removes predictions from Google autocomplete that are based on valid legal requests, those that are related to spam and those that relate to piracy.

 

Control mechanisms in place in Google Autocomplete:


Google does its best when it comes to controlling inappropriate predictions but with sifting through billions of searches per day sometimes inappropriate predictions on Google autocomplete slip through the cracks and that is why sometimes we see things that at times can be shocking.

Google has also started a feedback tool since last year that has been useful to them in removing unwanted predictions from Google autocomplete. They also plan on increasing the criteria for determining what is considered hateful in removing unwanted suggestions from Google autocomplete.

Reporting of Unwanted predictions:


Individuals too now can report anything that appears inappropriate on Google autocomplete. For those using a desktop there is “report inappropriate predictions” link that appears on the bottom of a search box and for those on Android, users can long press on the prediction to report it.

An Augmented Reality Microscope for Cancer Detection

An Augmented Reality Microscope will help in detecting cancer cells in upcoming days

With each passing day virtual reality, augmented reality and machine learning are opening new pathways in varied medical disciplines. It has been found that the application of the machine learning in varied medical departments specifically the radiology, ophthalmology, dermatology and pathology can help in deriving accurate and precise reports of the patients on global scale which can in turn boost the overall health sector on global level.



Google research team has come with an innovative and promising Augmented Reality Microscope, which has started showing remarkable results in detecting the breast cancer symptoms with highest rate of accuracy found only in very few trained pathologists.

This augmented reality microscope can perform a wide range of task like offering visual feedback, in form of the heat maps, contours, arrows, animation as well as some texts. As it is being powered by the machine learning it has got the ability to perform some problem solving as well as like going through smart object detection, classification as well as the quantification.

Google researchers have developed the augmented reality microscope based on the modern computation models along with the deep learning models using TensorFlow. The use of the machine learning algorithm helps in getting the output right on the screen in real time.

Detecting breast cancer based using new algorithms

Google researchers has trained this augmented reality microscope to run two very different cancer detection algorithms in order to detect cancer with highest rate of accuracy.One algorithm allows the augmented reality microscope to detect the breast cancer metastases present in the lymph node while the other algorithm trains it to detect the prostate cancer present in the prostatectomy specimens.

As it is able to take snaps in higher magnification of 4-40x, it allows the physician or researchers to have a look at the growing tumour regions with the green contour right on their screen. Furthermore these detailed imaging of the cells also allows the doctors or pathologist to carefully study the area under the influence of tumours cells without any issues.

Future application of the augmented reality microscope

Google is hopeful that augmented reality microscope will find its due place in the global health sector market along with making a huge impact in the same. It will be a great asset for the developing countries where it becomes extremely difficulty to detect the common infectious disease like tuberculosis and malaria in the early stages.

Apart from being robust in nature it is also quite light weight which will help it in finding it easily adoptable in wide varieties of industries globally apart from the pathology.

Secondly augmented reality microscope will also be finding a huge success in the digital industry here it can be used to create digital workflow prints which aren’t’ possible to be done by the modern scanners.

Healthcare will certainly be the prime focus of the Google in establishing, introducing and marketing the augmented reality microscope in the upcoming days but tech giant is also looking forward to bring this revolutionary device to the life research and material science disciples as well.

This Fire Detecting Wallpaper Can Turn an Entire Room into an Alarm

Fire Detecting Wallpaper

Fire Detecting Wallpaper: The wallpaper of the future!

Have you ever heard of wallpaper that can not only detect fire in the area that it is in but also helps in preventing its spread? Well neither have I until now that is. Researchers have come up with wallpaper that can detect fire and which is also fire resistant. Made of a material that is found in bone teeth and hormones, yes you read right, this fire detecting wallpaper, may actually stop the spread of flames and also alert you to the fact that your house is on fire.

Those colorful, beautiful wallpaper that you find in stores today are actually highly flammable made of such materials such as plant cellulose fibers and synthetic polymers, these wallpapers will help a fire spread in the nick of time making recovery of anything near impossible. Researchers of the fire detecting wallpaper have swapped out those flammable materials for something strange yet environmentally friendly.


The strange material in fire detecting wallpaper:

Fire detecting wallpaper is made of a material commonly found in bone teeth and hormone, (God knows where they got the idea from), this material known as hydroxyapatite is fashioned into long and by that I mean really long nanowires to give it high flexibility.

This hydroxyapatite material, that is used to make the fire detecting wallpaper, actually helps the wallpaper in preventing the spread of flames.

Making the fire detecting wallpaper “smart”:

Researchers didn’t just make the fire detecting wallpaper preventive of fire, they also wanted to make it “smart”. To do this they added sensors to the fire detecting wallpaper made from drops of graphene oxide in an inky mixture.

This graphene oxide acts in two ways, at room temp, it acts as an insulator, that is it blocks the flow of electricity while under high temperature say when there is a fire, it makes the fire detecting wallpaper conductive and this completes a circuit that sound an alarm.

Researchers also boast that this alarm on the fire detecting wallpaper can last for a prolonged period of more than five minutes.

So to fit it all in one nice package, the fire detecting wallpaper is not only non-flammable but also high in temperature resistance and has an automatic fire alarm.

The wallpaper that you find in today’s stores are highly flammable and won’t do nothing when it comes to a fire in the house while the fire detecting wallpaper has a high flexibility, it can also be processed into various shapes, made in different colors and made with a commercial printer.

But all this won’t come cheap, the fire detecting wallpaper, because of their materials come at a very steep price tag. They may be environmentally friendly but not really pocket friendly, making you think that you’d rather take your chances when and if there is a fire with normal wallpaper.

The next thing on the agenda, therefore, for scientists is that they now are looking for more cost effective ways of making fire detecting wallpaper, that will be easy on a person’s wallet.

Huge Google Sheets Update Introduces Macros

Google Sheets Update

Google Updates Google Sheets by Bringing in Macros to the Sheet

As with all Google products, at some point or the other, they all undergo some updates, it’s no different for Google sheets too. One of the major updates to Google sheets will be the addition of macros, which many are relieved to see on the Google platform. Who’s to say this won’t bring Microsoft excel users to Google sheets. Adding macros to Google sheets will give those hard core users of spreadsheets a much needed break as they won’t have to do the same thing over and over again.

Being a part of every other major suite out there, macros was sorely missing out in Google sheets. This addition to Google’s sheets will be a big thumbs up in their favor. With this Google sheets update, users will be able to finally record macros. Doing the same thing over and over again is boring and not to mention time consuming and with the advent of computers we thought we could put all that in the past but for a long time not having Macros in Google sheets seemed that we were still in that past.

Adding Macros to Google sheets: 


Adding Macros to Google sheets may be the most useful update to Google Sheets in a long long time. Now you will be able to see a new “record Macros” feature present in the tool bar that does exactly what you hope it would do- to stop you from having to repeat instructions again and again.

All you have to do is start your recording, go through your steps and when it is all done sit back and relax and by that I mean start the whole process again by simply running macros again.

The future is here with Google sheets at last. Now you needn’t spend more time on formatting and reformatting the same spreadsheet again and again or until you pull out all the hair on your head.

Going further, Google sheets even converts your macros into Apps script code, so if you are so inclined to make any changes you can always edit that app script.

Adding other features to Google Sheets:


Macros is not the only new feature to be added on to Google sheets. You can now also add page breaks to demarcate the pages you want to print, customize page sizes, the option to convert a cell into a check box list, there are also new options for row and column grouping and you can now even group data according to time frame like by week, month or year.

Google is even adding artificial intelligence to Google sheets. Google has even added intelligent pivot tables in their Google sheets which will help in analyzing and helping the user in getting more insights into their data irrespective of their skills in data analytics.

With “Explore” found in Google sheets, you will now be able to decipher the data on spreadsheets more easily than ever before. This feature uses machine intelligence to do that.

Direct High-Speed Charging of Electric Cars by Solar Panels

Direct Charging of Electric Cars

Charging Electric cars via a solar panel

Electric cars are now the “in thing”. With this fad on the up and up, many are now looking for ways to charge the car in ways that can be energy efficient. The whole point of these electric cars is that they should not take up much fuel and can be charged from renewable sources of energy that does not require the burning of fossil fuels, which would otherwise be the same thing as filling up the car with all fuel. Therefore researchers have now discovered a novel way to charge these electric cars using solar energy.

Researchers are now considering charging electric cars using solar panels. By using this method of charging the cars, people will not only save the environment from the burning of fossil fuels but will also be using a renewable source of energy, this is besides getting tax concessions.

Charging electric cars using solar panels and their problems: 


Present practice in using a solar panel means that charge from the solar panel has to be converted from direct current to alternating current to charge an electric car. This normally would require a 50Hz AC network, to convert the direct current into alternating current.

But this method is not really beneficial for anyone. In that it is not cost effective or efficient. This is because of two main reasons. To convert current to AC involves a lot of costs and needs many steps. Secondly, to convert from DC to AC requires two converters one for the solar panel and the other for the car, again leading to high costs and installments.

What’s the solution then? 


A better alternative as discovered by the researchers is to use a single converter that charges the car from the panels via a DC link which connects to the AC electricity grid.

Researchers then came up with a 10kW converter that has an internal DC link and three terminals that would allow the car to charge both from the solar panel and the electricity grid.

What’s so good about this method is that the integrated DC charger has a higher efficiency and is three times smaller than the current practice.

Another advantage of using this method is that not only will you be able to charge your car, you will now also be able to charge your entire house using this new method. You could also return the electricity back to the grid that is not before first converting it into AC.

The Future of Charging Electric cars: 


This system can be expanded to connect several chargers to solar panels thus expanding its use to business parks and residential areas. The company Power Research Electronics has gone a step further and made this theoretical system a reality by developing a number of high speed charging stations of this type.
In this way electric cars will not only consume less fuel, thereby burning less fossil fuel and in turn less damage to the atmosphere, but will also earn tax concessions by using a renewable source of energy.
