We can’t deny the fact
that our personal and professional life relies on the internet! Today we are
all dependent upon the technology. Almost a decade ago, we used to rely on all
manual ways to fulfill our objectives and never imagined that in this era, we
even think of machine learning applications.


We never thought that
before commencing from a place to reach the desired destination, we could check
the exact status of traffic on that route. Or for that matter, ten years ago it
was tough to believe that we can order food with just a few clicks! In fact,
did you ever thought about saying ‘Ok
Google
or Hey Siri’ and in
return, somebody will speak to you and do as you want them to do!


So, if we take a sneak
peek into this, it is actually the science that has made this technology so
strong. If we dig deeper, it is the outcome of the Artificial Intelligence and
Machine Learning Application that we are using today in disguise. When I say
disguise, it means today most of us are in contact with these real-time machine
learning business applications. But if somebody asks ‘What is Machine Learning’; it will be tough to answer. So
in this article, we will cover some illustrious real-time applications of
machine learning.


Here is the list of 13 Best Machine Learning
Applications:


Machine Learning helps to improve business decisions, boost productivity, detect disease, forecast the weather, and much more. Basically, a machine learns automatically from the inputs. Some of the best machine learning examples are mentioned below:


1). Traffic Alerts


How
does Google Maps know that you are on the fastest route despite the traffic is
high?


So,
it is a combination of multiple factors like how many people are currently
using the services of Google Maps, historic data of that route, and some
real-time techniques. While you use Google maps, you are allowing the app to
use data like:



  • Your location
  • Your average traveling speed
  • Answers to the questions like ‘does the route
    still have traffic’?
  • Day, time, and any specific occasion


All
such data is captured and stored by the application. By using this data, AI
& machine learning algorithms make the right conclusions and give you the
exact information.

The updated feature of Google Maps also helps us to know how far is the upcoming bus from a specific stop and even make predictions on the bus delays. Further, the machines are so intelligent that they can even tell you how crowded the bus or train is so that you can make a call to board the bus!


2). Image Recognition


For
humans, it is very easy to recognize any image. For example, imagine a car in
your mind, I am sure you can recall the image of a car, its brand, and in fact
the color. But, for a computer, the images are just some array of numerical
values and that is why it uses image processing algorithms to look for patterns
in digital images (videos, graphics, or still images). Using algorithms,
computers work on pattern recognition and machine learning algorithms can
recognize any form of visuals.


So how does machine learning go about facial
recognition?





Can
you unlock a phone simply by looking at it? If yes, you are using machine
learning. The high-end camera of your phone recognizes 80 nodal points on a
human face and machine learning technologies to measure the variable of a
person’s face and unlock the phone. 


Phone
unlocking is now among common machine learning applications. Now we from Gen Z
generation, are in a world where we use face recognition to make quick bank
payments. Other image recognition uses are:



  • Drones
  • Manufacturing
  • Self-driving cars
  • Military surveillance
  • Forest Activities


3). Video Surveillance


This
is one of the most advanced applications of machine learning and AI. Videos
give a better opportunity to fetch valuable information from automated
surveillance devices compared to any other source. This is only possible
because machines keep a better outlook for the objects compared to human minds.



Video surveillance


Video surveillance is used for different
purposes like:



  • Copper theft prevention
  • Abnormal event detection
  • Facility protections
  • Operation monitoring
  • Parking lots
  • Traffic monitoring
  • Shopping patterns


Surveillance footages are the best machine learning datasets because of their accuracy but these footages are hard to obtain. Thus, training the object detector comes into existence so that these objects can easily recognize the targets from normal images.


4). Sentiment Analysis


Sentiment
analysis is a top-notch machine learning application that refers to sentiment
classification, opinion mining, and analyzing emotions. Using this model,
machines groom themselves to analyze sentiments based on the words. They can
identify if the words are said in a positive, negative, or neutral notion.
Also, they can define the magnitude of these words.


With
the help of the process called Natural Language Processing (NLP), data-miners
automatically extract and conclude the opinion by analyzing both types of
machine learning algorithms – supervised and unsupervised data. Companies that
are dealing with customers use this model to improve customer experience based
on the feedback.


In
the below example Machine Learning model interprets the clients’ tweets and
bifurcates it into positive and negative notions. This gives the brand a quick
view of what their clients are saying about them and accordingly they can make
efforts to resolve any negative feedback.

Another
machine learning example is – Music applications. Apps like Ganna.com, Jiosaavn
also suggest music based on user sentiments by analyzing the history of songs
played, favorite playlists, and even time of listings music.


Benefits of Adopting Sentiment Analysis



  • Effective brand and social media monitoring
  • Enhanced customer support
  • Competitive analysis
  • Better tracking of employee feedbacks and UGC (user-generated content like reviews)






5). Product Recommendation


While
shopping on eCommerce brands like Amazon and Flipkart, you get to see
recommended items or options like ‘users
who bought this product also bought’; ‘users also buy this along with this
product’!


All
these are the outcomes of advanced machine learning training wherein the system
learns individual patterns of users and suggests new or additional products to
buy.



product suggestions


Not only on ecommerce apps, but even you will also get to see similar product suggestions on Google, YouTube, and freemium apps. Yes, this is a real-world application of machine learning.


6). Online support using Chatbots


When
you use any application say some banking app, you see an option called ‘chat with us’. So these are chatbots
running on the concepts of machine learning. These bots can recognize the type
of questions, and accordingly, give quick answers to resolve the query by
extracting the right parameters.


To
give precise solutions, these bots also use a technique called decision trees
in machine learning. Depending upon the business models, the types of questions
and answers change. Thus, decision trees help the machine to learn quickly and
satisfy the clients.

7). Google Translate


Traveling
to a new place is always thrilling but the only enigma is to understand the
common language of that place. To solve this dilemma, Google has launched an
app that can help in easy translation of any language.



Google Translate


Google uses ‘Google Neural Machine Translation’ that has the ability to absorb thousands of languages, words, and dictionaries and transmute any sentence in the desired language.


8). Online Video Streaming Applications


Online
video apps like Netflix and Amazon Prime are the pioneers of video streaming.
Now almost every TV channel is also having its online video content streaming
application that attracts viewers based on their personalized interests.

technique called machine learning. The apps capture the data of user’s
activities and accordingly gush video suggestions.


What kind of data these apps monitor?



  • Day and time of watching content
  • Type of content you prefer to watch
  • Pause, Rewind or Fast Forward activities
  • Browsing pattern
  • Trailers you watch before actually watching
    the movie/show


Based on these trends, machine learning frameworks & applications, businesses are able to engage their audience by providing quality streaming experience.


9). Virtual Professional Assistants


Machine
learning-based VPA is among the most popular examples of machine learning
applications. With a surge in smart devices usage, machines are becoming
smarter in adopting human behaviors.


Have
you asked Google Assistant to wake you up at 6 AM? Or have you commanded Siri
to navigate you to your favorite restaurant?

10). Machine Learning Usage in Social Media



Social Media


When
you are about to tag someone on Facebook, before even mentioning the name of
the person in the image, Facebook gives you a suggestion and 99.99% it gives
the right name. How does Facebook know the name of the person you are about to
tag in the image?


Yes,
you are correct, it is possible and the credit goes to machine learning. This
is just a small part of big data machine learning. AI and machine learning give
the exact insights based on the data collected. By implementing machine
learning, marketers get insights on:



  • How to boost the open rate of email marketing?
  • Which campaigns have done really well and why
    they could do so?
  • How do clients feel when they purchase any
    product?
  • What kind of content users prefer to
    read/watch depending upon their age, gender, and location?
  • Which is the best time to schedule a campaign
    or a post?


 Such crucial information helps businesses to multiply their sales volumes through social media.
