2. What is Machine Learning?
Machine learning is an application of artificial intelligence (AI) that
provides systems the ability to automatically learn and improve from
experience without being explicitly programmed. Machine learning
focuses on the development of computer programs that can
access data and use it learn for themselves.
The process of learning begins with observations or data, such as
examples, direct experience, or instruction, in order to look for
patterns in data and make better decisions in the future based on the
examples that we provide. The primary aim is to allow the
computers learn automatically without human intervention or
assistance and adjust actions accordingly.
Arthur Samuel in 1959:
“[Machine Learning is the] field of study that gives computers the
ability to learn without being explicitly programmed.”
And more recently, in 1997, Tom Mitchel :
“A computer program is said to learn from experience E with
respect to some task T and some performance measure P, if its
performance on T, as measured by P, improves with experience
E.” -- Tom Mitchell, Carnegie Mellon University :
Machine learning enables analysis of massive quantities of data. While
it generally delivers faster, more accurate results in order to identify
profitable opportunities or dangerous risks, it may also require
additional time and resources to train it properly. Combining machine

3. learning with AI and cognitive technologies can make it even more
effective in processing large volumes of information.
 Algorithm by learning Style:
There are different ways an algorithm can model a problem based on
its interaction with the experience or environment or whatever we
count to call the input data.
Three different styles in machine learning algorithm:
1.Semi-Supervised Learning
 Input data is a mixture of labeled and unlabelled examples.
 There is a desired prediction problem but the model must
learn the structures to organize the data as well as make
predictions.
 Example problems are classification and regression.
 Example algorithms are extensions to other flexible
methods that make assumptions about how to model the
unlabeled data.
2. Supervised Learning
 Input data is called training data and has a known label or
result such as spam/not-spam or a stock price at a time.
 A model is prepared through a training process in which it
is required to make predictions and is corrected when those
predictions are wrong. The training process continues until the
model achieves a desired level of accuracy on the training data.

4.  Example problems are classification and regression.
3.Unsupervised Learning
 Input data is not labeled and does not have a known result.
 A model is prepared by deducing structures present in the
input data. This may be to extract general rules. It may be
through a mathematical process to systematically reduce
redundancy, or it may be to organize data by similarity.
 Example problems are clustering, dimensionality reduction
and association rule learning.
 Example algorithms include: the Apriori algorithm and k-
Means.
 How will machine learning work with humans for
optimal marketing?
Machine learning will offer key insights into optimization, helping brands
understand what people want to read.
Humans will be in charge of creating high-quality content that speaks to
the needs of the customers, as detailed by the machine learning.
Machine learning will analyze customer behavior on websites to better
understand how people progress through the buyer’s journey.
Machine learning will take the content created by people and develop a
more personalized experience.

5. Machine learning will be an important part of marketing in the future, as
it will help brands better understand customer behavior and what people
want to see online. Humans will always be in charge of the creative
process, but this type of learning will make it easier to create a superior
user experience.
Learning system model:
Machine learning refers to a system capable of acquiring and
integrating the knowledge automatically. The capability of the systems
to learn from experience, training, analytical observation, and other
means, results in a system that can continuously self-improve and
thereby exhibit efficiency and effectiveness.
A machine learning system usually starts with some knowledge and a
corresponding knowledge organization so that it can interpret, analyze,
and test the knowledge acquired.
The figure shown besides
is a typical learning
system model.
It consists of the
following components.
1. Learning element
2. Knowledge base
3. Performance element
4. Feedback element
5. Standard system.

6. Learning System Model
The figure shown above is a typical learning system model. It consists of the
following components.
1. Learning element
2. Knowledge base
3. Performance element
4. Feedback element
5. Standard system.
1. Learning element
It receives and processes the input obtained from a person ( i.e. a teacher),
from reference material like magazines, journals, etc, or from the environment
at large.
2. Knowledge base
This is somewhat similar to the database. Initially it may contain some basic
knowledge. Thereafter it receives more knowledge which may be new and so be
added as it is or it may replace the existing knowledge.

7. 3. Performance element
It uses the updated knowledge base to perform some tasks or solves some
problems and produces the corresponding output.
4. Feedback element
It is receiving the two inputs, one from learning element and one from standard
(or idealized) system. This is to identify the differences between the two inputs.
The feedback is used to determine what should be done in order to produce the
correct output.
5. Standard system
It is a trained person or a computer program that is able to produce the
correct output. In order to check whether the machine learning system has
learned well, the same input is given to the standard system. The outputs of
standard system and that of performance element are given as inputs to the
feedback element for the comparison. Standard system is also called idealized
system. The sequence of operations described above may be repeated until
the system gets the desired perfection.
There are several factors affecting the performance are:
• Types of training provided
• The form and extent of any initial background knowledge
• The type of feedback provided
• The learning algorithms used.
Training is the process of making the system able to learn. It may consist of
randomly selected examples that include a variety of facts and details including

8. irrelevant data. The learning techniques can be characterized as a search
through a space of possible hypotheses or solutions. Background knowledge
can be used to make learning more efficient by reducing the search space. The
feedback may be a simple yes or no type of evaluation or it may contain useful
information describing why a particular action was good or bad. If the feedback
is always reliable and carries useful information, the learning process will be
faster and the resultant knowledge will be correct.
The success of machine learning system also depends on the algorithms. These
algorithms control the search to find and build the knowledge structures. The
algorithms should extract useful information from training examples. There are
several machine learning techniques available. I have explored some of the
important techniques.
A.I vs. Machine Learning vs. Deep Learning
AI and machine learning are often used interchangeably, especially in the realm
of big data. But these aren’t the same thing, and it is important to understand
how these can be applied differently.
Artificial intelligence is a broader concept than machine learning, which
addresses the use of computers to mimic the cognitive functions of humans.
When machines carry out tasks based on algorithms in an “intelligent”
manner, that is AI. Machine learning is a subset of AI and focuses on the ability
of machines to receive a set of data and learn for themselves, changing
algorithms as they learn more about the information they are processing.

9. Training computers to think like humans is achieved partly through the use of
neural networks. Neural networks are a series of algorithms modeled after the
human brain. Just as the brain can recognize patterns and help us categorize
and classify information, neural networks do the same for computers. The
brain is constantly trying to make sense of the information it is processing, and
to do this, it labels and assigns items to categories. When we encounter
something new, we try to compare it to a known item to help us understand and
make sense of it. Neural networks do the same for computers.
Benefits of neural networks:
• Extract meaning from complicated data
• Detect trends and identify patterns too complex for humans to notice
• Learn by example
• Speed advantages
Deep learning goes yet another level deeper and can be considered a subset of
machine learning. The concept of deep learning is sometimes just referred to
as "deep neural networks," referring to the many layers involved. A neural

10. network may only have a single layer of data, while a deep neural network has
two or more. The layers can be seen as a nested hierarchy of related concepts
or decision trees. The answer to one question leads to a set of deeper related
questions.
Deep learning networks need to see large quantities of items in order to be
trained. Instead of being programmed with the edges that define items, the
systems learn from exposure to millions of data points. An early example of
this is the Google Brain learning to recognize cats after being shown over ten
million images. Deep learning networks do not need to be programmed with
criteria that define items; they are able to identify edges through being
exposed to large amounts of data.
What is the Jupyter Notebook?
 The Jupyter Notebook is an interactive computing environment that
enables users to author notebook documents that include: - Live code -
Interactive widgets - Plots - Narrative text - Equations - Images - Video

11.  These documents provide a complete and self-contained record of a
computation that can be converted to various formats and shared with
others using email, Dropbox, version control systems (like git/GitHub)
or nbviewer.jupyter.org.
Components
The Jupyter Notebook combines three components:
 The notebook web application: An interactive web application for
writing and running code interactively and authoring notebook
documents.
 Kernels: Separate processes started by the notebook web application
that runs users’ code in a given language and returns output back to the
notebook web application. The kernel also handles things like
computations for interactive widgets, tab completion and introspection.
 Notebook documents: Self-contained documents that contain a
representation of all content visible in the notebook web application,
including inputs and outputs of the computations, narrative text,
equations, images, and rich media representations of objects. Each
notebook document has its own kernel.
Notebook web application
The notebook web application enables users to:
 Edit code in the browser, with automatic syntax highlighting,
indentation, and tab completion/introspection.
 Run code from the browser, with the results of computations attached
to the code which generated them.

12.  See the results of computations with rich media representations, such
as HTML, LaTeX, PNG, SVG, PDF, etc.
 Create and use interactive JavaScript widgets, which bind interactive
user interface controls and visualizations to reactive kernel side
computations.
Author narrative text using the Markdown markup language.
+++++++++ STARTUPS TRANSFORMING HEALTHCARE AI+++++++++
Important points are +++++ Taking care of human health is a quite
intricate job that requires broad and multiple aspects of the
healthcare industry to work together.
Healthcare industry is already overburdened with the exploding
population and lack of trained doctors. The ratio of doctor to patients
in India is 1:1700 which is far higher than the recommended ratio of 1 in
every 1000 patients by WHO.
The spontaneous increase in the count of efficient healthcare
providers is not possible. But the access to intelligent and smart
technologies can enhance the productivity and precision of existing

13. ones in serving more patients in a specific time, with the ease to
improve healthcare outcomes and in lowering the healthcare expense.
Artificial Intelligence (AI) has the ability to throttle the pace of
advancements in almost all industrial segments.
According to John McCarthy, the father of Artificial Intelligence;
“Artificial Intelligence is the science and engineering of making
intelligent machines, especially intelligent computer programs.”
AI helps humans to amalgamate human intelligence with computer
technology to enhance the potential of the healthcare industry to serve
better.
Know about some healthcare start-ups in India who are adopting AI to
accelerate the healthcare industry in a more efficient and cost-
effective way.
