AI – Basics
Father of Artificial Intelligence is John McCarthy.
The science and engineering of making intelligent
machines, especially intelligent computer programs.
Artificial Intelligence is a way of making a
computer, a computer-controlled robot, or a software
think intelligently, in the similar manner the intelligent
humans think.
AI is accomplished by studying how human brain
thinks and how humans learn, decide, and work while
trying to solve a problem, and then using the outcomes
of this study as a basis of developing intelligent
software and systems.

multiplication.
The library’s name is actually short for "Numeric
Python" or "Numerical Python".
NumPy is memory efficiency, meaning it can handle
the vast amount of data more accessible than any other
library.

analysis
Accessible to everbody, and reusable in various
contexts
Built on Numpy, SciPy, and matplotlib
Open source, commercially usable - BSD license

Tensorflow
Developed by Google
Open Source
The Advantages of TensorFlow are - It has excellent
community support, It is designed to use various backend
software (GPUs, ASIC), etc. and also highly parallel, It has a
unique approach that allows monitoring the training progress
of our models and tracking several metrics, & Its performance
is high and matching the best in the industry.
There are 4 main tensor type you can create in TensorFlow -
tf.Variable, tf.constant, tf.placeholder, & tf.SparseTensor.

AI - Types
Symbolic Based  Computer Vision, Image
Processing, Camera, Video, Image, Robotics.
Machine Learning  Based on data. Feed machine
with lot of data, so it can learn and perform. (Ex – Lot
of data of Sales versus Advertising spent, then ML can
learn and draw pattern in more than 100 and 1000
dimensions)
ML  Classification & Prediction (Shop Ex –
classifying customers as per data (old / new, age) and
assign toys, and predict their next interest of purchase)

Machine Learning
Machine learning  field of computer science, an
application of artificial intelligence, which provides
computer systems the ability to learn with data and
improve from experience without being explicitly
programmed.
The main focus of machine learning is to allow the
computers learn automatically without human
intervention.
Observations of data  The data can be some
examples, instruction or some direct experiences too.
Then on the basis of this input, machine makes better
decision by looking for some patterns in data.

Data Input types
Excel Data  Numbers and Strings
Images or Videos
Audio Signals

Types of Machine Learning Algorithms
Supervised machine learning algorithms
Unsupervised machine learning algorithms
Reinforcement machine learning algorithms
AI is a combination of complex algorithms
from the various mathematical domains such as
Algebra, Calculus, and Probability and
Statistics.

Supervised machine learning algorithms
This is the most commonly used machine learning
algorithm.
It is called supervised because the process of
algorithm learning from the training dataset can be
thought of as a teacher supervising the learning
process. In this kind of ML algorithm, the possible
outcomes are already known and training data is also
labeled with correct answers.

Mainly supervised leaning problems can be divided
into the following two kinds of problems −
Classification − A problem is called classification
problem when we have the categorized output such as
“black”, “teaching”, “non-teaching”, etc. (Ex: Classify
all types of flowers, Classify Dolphin or Seahorse)
Regression − A problem is called regression problem
when we have the real value output such as “distance”,
“kilogram”, etc.

Supervised - Regression
Regression is one of the most important statistical and
machine learning tools.
It may be defined as the parametric technique that allows us
to make decisions based upon data or in other words allows us
to make predictions based upon data by learning the
relationship between input and output variables. Here, the
output variables dependent on the input variables, are
continuous-valued real numbers.
In regression, the relationship between input and output
variables matters and it helps us in understanding how the
value of the output variable changes with the change of input
variable. Regression is frequently used for prediction of prices,
economics, variations, and so on.

Gaussian naive bayes
Support Vector Machines (SVM)
Logistic Regression
Random Forest Classifier
K-Nearest Neighbors (KNN) Classifier

Unsupervised machine learning algorithms
algorithms do not have any supervisor to provide
any sort of guidance. That is why unsupervised
machine learning algorithms are closely aligned with
what some call true artificial intelligence.
Suppose we have input variable x, then there will be
no corresponding output variables as there is in
supervised learning algorithms.
In simple words, we can say that in unsupervised
learning there will be no correct answer and no teacher
for the guidance. Algorithms help to discover
interesting patterns in data.

Unsupervised learning problems can be divided into the
following two kinds of problem −
Clustering − In clustering problems, we need to discover the
inherent groupings in the data. The main goal of clustering is
to group the data on the basis of similarity and dissimilarity.
For example, grouping customers by their purchasing
behavior.
Association − A problem is called association problem
because such kinds of problem require discovering the rules
that describe large portions of our data. For example, finding
the customers who buy both x and y.

K-means clustering algorithm
Mean Shift clustering Algorithm

Reinforcement machine learning algorithms
These kinds of machine learning algorithms are used
very less.
These algorithms train the systems to make specific
decisions. Basically, the machine is exposed to an
environment where it trains itself continually using the
trial and error method. These algorithms learn from
past experience and try to capture the best possible
knowledge to make accurate decisions.
Markov Decision Process is an example of
reinforcement machine learning algorithms.

Dataset Analysis
Dataset  Columns are called as  Features, Dimensions,
Attributes, Variables, Parameters etc.
Balanced or Imbalanced Data.
Output  Class or Label
Parameters 
Check value counts of required parameters (Ex output)
Fill empty cells with Average value of that parameters.
Remove empty Cells.
Remove imbalanced data
Delete unwanted columns

Preprocessing the Data
ML require formatted data to start the training
process. We must prepare or format data in a certain
way so that it can be supplied as an input to ML
algorithms.
In our daily life, we deal with lots of data but this
data is in raw form. To provide the data as the input of
machine learning algorithms, we need to convert it
into a meaningful data.
In other simple words, we can say that before
providing the data to the machine learning algorithms
we need to preprocess the data.

Preprocessing Steps
Importing the useful packages  import numpy, sklearn,
matplotlib etc.
Example Dataset  online, library or download in excel csv
format.
Binarization  all the values above 0.5(threshold value)
would be converted to 1 and all the values below 0.5 would be
converted to 0.
Mean Removal
Scaling
Normalization
Labeling the data
Train data & Test data

Input Image
 When a computer sees an image, it will see an array of pixel
values.
 Let's say we have a color image in JPG form and its size is
480 x 480. The representative array will be 480 x 480 x 3
array of numbers (The 3 refers to RGB values).
 Each of these numbers is given a value from 0 to 255 which
describes the pixel intensity at that point.

Color – Pixel Intensity
Shape
Texture
