artificial intelligence for people in a
hurry
the easiest way to think about
artificial intelligence is in the
context of a human
after all humans are the most
intelligent creatures we know of
ai is a broad branch of computer science
the goal of ai is to create systems that
can function intelligently and
independently
humans can speak and listen to
communicate through language
this is the field of speech recognition
much of speech recognition is
statistically based
hence it's called statistical learning
humans can write and read text in a
language
this is a field of nlp
or natural language processing
humans can see with their eyes and
process what they see
this is a field of computer vision
computer vision falls under the symbolic
way for computers to process information
recently there's been another way which
i'll come to later
humans recognize the scene around them
through their eyes which create images
of that world
this field of image processing which
even though is not directly related to
ai
is required for computer vision
humans can understand their environment
and move around fluidly
this is a field of robotics
humans have the ability to see patterns
such as grouping of like objects
this is the field of pattern recognition
machines are even better at pattern
recognition because they can use more
data and dimensions of data
this is the field of machine learning
now let's talk about the human brain
the human brain is a network of neurons
and we use these to learn things
if we can replicate the structure and
the function of the human brain
we might be able to get cognitive
capabilities in machines
this is a field of neural networks
if these networks are more complex and
deeper
and we use those to learn complex things
that is the field of deep learning
there are different types of deep
learning in machines which are
essentially different techniques to
replicate what the human brain does
if we get the network to scan images
from left to right top to bottom it's a
convolution neural network
a cnn is used to recognize objects in a
scene
this is how computer vision fits in
and object recognition is accomplished
through ai
humans can remember the past
like what you had for dinner last night
well at least most of you
we can get a neural network to remember
a limited past
this is a recurrent neural network
as you see there are two ways ai works
one is symbolic based and another is
data based
for the database side called machine
learning we need to feed the machine
lots of data before it can learn
for example if you had lots of data for
sales versus advertising spend
you can plot that data to see some kind
of a pattern
if the machine can learn this pattern
then it can make predictions based on
what it has learned
while one or two or even three
dimensions is easy for
humans to understand and learn
machines can learn in many more
dimensions like even hundreds or
thousands
that's why machines can look at lots of
high dimensional data and determine
patterns
once it learns these patterns it can
make predictions that humans can't even
come close to
we can use all these machine learning
techniques to do one of two things
classification or prediction
as an example when you use some
information about customers to assign
new customers to a group like young
adults
then you are classifying that customer
if you use data to predict if they're
likely to defect to a competitor
then you're making a prediction
there's another way to think about
learning algorithms used for ai
if you train an algorithm with data
that also contains the answer
then it's called supervised learning
for example when you train a machine to
recognize your friends by name
you'll need to identify them for the
computer
if you train an algorithm with data
where you want the machine to figure out
the patterns
then it's unsupervised learning
for example you might want to feed the
data about celestial objects in the
universe and expect the machine to come
up with patterns
in that data by itself
if you give any algorithm a goal and
expect the machine through trial and
error to achieve that goal
then it's called reinforcement learning
a robot's attempt to climb over the wall
until it succeeds is an example of that
so there you go
