Applications of Machine Learning
If you have connection with technical world then you have must heard about Machine Learning. It is one of the modern technologies. Machine Learning is the future of our tech industry. Nowadays, every company depends upon this Machine Learning. So, it is also a great opportunity for ML developers. In this article we are going to discuss about different applications of Machine Learning in details.
Detection of spam emails
You have surely used emails. It is one of the important communication systems. Mainly official information is shared through email. But it is often seen that many ad agencies collects your mail from different sources and they send their advertisements to you via mail. But it is amazing that in Gmail we find only important mails in our inbox. You can see other folders there. Spam folder is the place where this type of unwanted mails goes. It happens because of Machine Learning. Gmail uses some Machine Learning techniques like multi-layer perceptron, decision tree and other things to detect spam mails. There are some criteria for detection like body, subject, rules etc.
Virtual assistant
Everyone is carrying smart phones in present days. Sometimes we use Google assistant to do something by our phone. Like Google assistant there are many virtual assistant like in laptops you can find Cortona, in apple sets you can find Siri. These assistants help us a lot by doing our job only using our voice command. We use these assistants to call someone, to check something, to find routes, even for typing messages. This all things can be done by virtual assistants. Virtual assistants also use Machine Learning technologies. They recognise our voice and then send it to cloud services and act accordingly.
Recommendation of products
When we go to Amazon or Flipkart for shopping, we find products similar to our previous purchases. Sometimes, we get shocked when we find some videos on Youtube related to the topics which we recently searched on Google. It is not any magic. It is the recommendation system. We can define a recommendation system as a system which can predict users' choices based on their previous activities. Recommendation system is part and parcel of Machine Learning. It helps companies to provide their best services to their customer. In some cases, recommendation system is simple but in some cases it may be complex.
Recognition of Images
It is one of the most used applications. In some apps, face recognition is used. Even in our phones there are systems to lock and unlock our phone by face recognition. You have surely noticed that when you upload one photo on Facebook with your friends who also use Facebook then it automatically suggests you to tag all of them. This thing happens because Facebook does face recognition in your image and detect the users in that image. There are also many other examples of face recognition. Face recognition is also used in security systems.
Self driving cars
It is one of the most exciting applications of Machine Learning. You must have heard about Tesla cars. This company is producing self driving cars. Just imagine that you are in car but you are not driving it though it is moving safely. Machine Learning is the key technology to do this impossible work executed. Tesla uses unsupervised Machine Learning technology to detect the people and the road. But we have to recognize that it is not hundred percent safe. In some cases, it happened that these self driving cars face accidents. Surely it is exciting but it needs more research to make it full proof.
Translation of languages
In these days of globalisation, it is important for us to interact with persons from different states and different countries. But the main barrier is the language. It is true that in modern society or in official work we can do this by using English language. But suppose you are going to talk with a common man who does not know a single bit of English then it is obvious that the communication will not happen. Machine Learning solves this problem also. The technology called machine translation helps people a lot in communication with persons from different languages. For this reason now we can understand every language of world by using our smart gadgets.
Fraud detection by Machine Learning
We use online payment more than cash payment but it also increases the probability of fraud. Nowadays, it often happens that we get to hear about frauds surrounding us. Many times we get fraud call or messages. They ask for OTP (one time password). If anyone gives it then he is going to lose all his money within some seconds. Frauds not only happen with common man but government offices also face frauds. Machine Learning can help us a lot in this thing. By using some algorithms, we can detect the fraud cases. Just think about a common man who have 50 lakhs in his account and he usually withdraw maximum 1 lakh. When the withdrawal amount increases to 1 lakh, the ML algorithm should alert the bank and the customer also. Many of us get this type of alert when unusual withdrawal happens in our account. Machine Learning helps a lot to prevent this type of fraud things.
Dynamic pricing
When we book cabs by some app, it happens to all of us that the prices varies from day to day and time to time. Even think that you and your friend booking car for same route but you are 10 minutes late for booking. Now, you are seeing that your friend is getting benefit for 50 Rs. This thing happens with all of us. When we book a flight ticket one month before travelling it costs less. But suppose you have to go urgently and you are booking just day before travelling then you will face much more cost than previous one. All these things happen due to dynamic pricing. Machine Learning plays a vital role here. When you book a car on app Machine Learning algorithm of this app detects how the route is busy and then it decides the costs. In a same manner for booking in plane tickets or train tickets you face extra charges. The algorithms check the route, passenger details, time left for travel then decide the fare for travelling. In this way Machine Learning helps the companies to fix the actual fare for passengers.
Medical treatments
Machine Learning is expanding its field everywhere. Medical world also uses Machine Learning technologies. Just think about some robotics operations. They are done by Machine Learning. When a drug is invented it is not possible to apply the drug for every human. But we do research on some people and use this small data for analysing the drug. This research is also done by using Machine Learning algorithms. It may happen that the doctor is not able to diagnose your disease by your symptoms. But it is obvious that using Machine Learning this problem can be solved.
Videos Surveillance
When Covid 19 hit the whole world with its severe effects we all were doing work from home. This thing has taught us to use online. Now we are comfortable with online systems. But think about examination process. It is difficult to conduct online exams because student may cheat when they are giving exams from their home. So to manage this problem one solution came forward and that is video surveillance. In this method we can see students’ activities while they are giving exams. But it is ok when there are 10 to 100 students. Just imagine about one university which has over fifty thousands of students. It is not possible for them to check the video by person. Here, we need Machine Learning. It is first set some example videos and then the Machine Learning model checks the videos randomly and if there is any issue then it informs the host of the examination. This method is used by many College and universities during pandemic. Even nowadays this method is used in various purposes.
Speech recognition
You may have searched something on Google or on YouTube by telling in your own voice. Machine Learning works in this case also. In speech recognition system our voice is converted into words or text. Then the text is searched in Google or YouTube as it happens. Personal virtual assistants also use this thing.
Traffic prediction
We all use Google map to find our routes to a destination. You have surely noticed that this app says us about the time to reach or the traffic in that road. This thing also happens due to Machine Learning.
