slide 1: Introduction to Machine Learning
What is Machine Learning
Machine Learning is field of artificial intelligence AI where the systems will be given
the ability to learn things automatically and make decisions with very less human
intervention.
Python Java and R are most popular skills when it comes to machine learning and
data science jobs.
slide 2: Advantages:
The operating speed of Machine learning algorithms is very fast.
Machine learning consumes and produces real-time data at incredible speeds.
For instance in case of grocery and department stores machine learning
customizes new offers very fast which means what it shows now would be
different after 1 hr.
Some advertising platforms like Google and Facebook are using machine
learning technology to grasp users’ internet behavior and tailor ads according to
the their search history.
Machine learning efficiently uses the resources that include some resources
which lead to automation of tasks.
Challenges
We cannot say that machine learning algorithms always work in every single
case.
Major challenge of machine learning is Acquisition. Since a large amount of data
is required to get the precise solution and input data is different for different
methods caution to be taken while giving data as input before processing. It
would lead to failure otherwise.
Natural Language processing is another major hurdle here. Although research is
under process it has to reach far more beyond.
McAfee said that the actual problem comes when machine learning commits errors. It
would be very difficult to diagnose and correct the error since it has to go through many
complexities.
slide 3: Applications
These are the industries where machine learning is making a revolution:
Education – This is going to bring a revolution in the education industry and the
methods of teaching. Machine Learning makes it possible to observe every student and
tailor the teaching methods according to the individual. Devices like Smart Whiteboards
have already made their way into this field.
Transportation – Self Driving Cars is the word that comes to our mind when we think of
AI in transportation. Ride-sharing giant Uber has already rolled out self-driving cars but
with some defects which usually happens and is putting a great deal of effort in
improvising it. Machine Learning/AI is going to affect many transport companies in the
near future.
Health Care – Machine Learning can be used in the diagnosis and treatment of illness.
Although robot surgeons operated remotely by human surgeons are introduced some
time back it still needs to go much further. Introduction of robot surgeons can minimize
the work and with the big data being given to the robots it would be easy to perform
some operation based on the similar incidents that occurred past.
Business and Marketing – Many Social media sites and e-commerce giants like
Facebook Amazon etc. have already been using AI algorithms to detect consumer
behavior and match content with their interest and needs. Most of us are familiar with
Google’s AI which is using Machine Learning to constantly improve search results.
The Chatbot is another example which is reducing human work. It sends automated
messages. Most of the service based companies are now taking to chatbots reducing
the number of human labors.
Financial Services – Clinc’s Finie app will provide you all the financial advice and
answers in the banking industry. This app is regarded as one of the most advanced
intelligent assistant technologies in the banking industry. If we talk about AI in financial
services then we must know about clinc which has been contributing a lot to the
financial industry.
slide 4: Feedzai is another platform which helps in fraud detection. Oh This is incredible.
It watches millions of unusual transactional behavior and spending patterns.
Many complex algorithms are being used in the banking industry that acts as
financial advisories taking many factors into consideration thus replacing the physical
advisories.
I’ve mentioned only few applications. Apart from the above there is a lot to come around in the
near future.
There is no need to open our jaw even if we say Machine Learning can change our lifestyle in
the near future.
Few Facts about machine learning
Do you know
20 percent of the C-Suite across 10 countries and 14 different industries
is using machine learning
Investment in AI by different countries is disproportionate U.S is the major
investor as of now.
Google’s Deep Learning can benefit health and save billions.
Chatbots will power 85 percent of customer service by 2020
€150 billion saved on healthcare by 2025
Amazon has reduced ‘click to ship’ time down to 15 minutes from around
75-90 minutes.
Internet-based Entertainment Company Netflix is investing heavily to
keep users engaged.
Above all Machine learning still requires humans.

10 Steps that leads to success in Machine Learning
1. The very first step is to understand what Machine Learning actually is.
2. The more data an algorithm has the more accurate it becomes. So collect more
data and avoid sampling if possible.
3. Selecting the best method from machine learning for a given problem will
determine our success in most cases.
4. Improper data collection will decrease the chance of building good generalizable
machine learning models.
5. Choosing method and the parameters related to it also plays a vital role.
6. Selecting the appropriate objective function for optimization also plays a key step
in the success.
slide 6: 7. Understand the generalization how good a model performs on unseen data
error before deployment.
8. Should constantly measure the effectiveness of the implementation and should
note the changes that affect the system in a good or bad way.
9. Should know how to handle semi-structured and unstructured data such as text
images etc.
10.Don’t just depend on one tool but try different and use few tools.
