Support vector machines (SVMs) are a supervised machine learning algorithm used for classification and regression analysis. SVMs find the optimal boundary, known as a hyperplane, that separates classes of data. This hyperplane maximizes the margin between the two classes. Extensions to the basic SVM model include soft margin classification to allow some misclassified points, methods for multi-class classification like one-vs-one and one-vs-all, and the use of kernel functions to handle non-linear decision boundaries. Real-world applications of SVMs include face detection, text categorization, image classification, and bioinformatics.
A Support Vector Machine (SVM) is a discriminative classifier formally defined by a separating hyperplane. In other words, given labeled training data (supervised learning), the algorithm outputs an optimal hyperplane which categorizes new examples. In two dimentional space this hyperplane is a line dividing a plane in two parts where in each class lay in either side.
In machine learning, support vector machines (SVMs, also support vector networks[1]) are supervised learning models with associated learning algorithms that analyze data and recognize patterns, used for classification and regression analysis. The basic SVM takes a set of input data and predicts, for each given input, which of two possible classes forms the output, making it a non-probabilistic binary linear classifier.

ensemble methods use multiple learning algorithms to obtain better predictive performance than could be obtained from any of the constituent learning algorithms alone.
An ensemble is itself a supervised learning algorithm, because it can be trained and then used to make predictions. The trained ensemble, therefore, represents a single hypothesis. This hypothesis, however, is not necessarily contained within the hypothesis space of the models from which it is built.
In this presentation, we approach a two-class classification problem. We try to find a plane that separates the class in the feature space, also called a hyperplane. If we can't find a hyperplane, then we can be creative in two ways: 1) We soften what we mean by separate, and 2) We enrich and enlarge the featured space so that separation is possible.

Support vector machines are widely used binary classifiers known for its ability to handle high dimensional data that classifies data by separating classes with a hyper-plane that maximizes the margin between them. The data points that are closest to hyper-plane are known as support vectors. Thus the selected decision boundary will be the one that minimizes the generalization error (by maximizing the margin between classes).
In machine learning, support-vector machines (SVMs, also support-vector networks) are supervised learning models with associated learning algorithms that analyze data for classification and regression analysis
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

1. SUPPORT VECTOR MACHINE
1. INTRODUCTION
2. LINEARLY SEPERABLE CASE
3. EXTENSION TO THE SVM MODEL
4. APPLICATION OF SVM IN REAL WORLD
2. SUPPORT VECTOR MACHINE
• It is a supervised machine learning algorithm
that helps in both classification and regression
problem statements.It finds an optimal boundary
known as hyperplane between different classes.
• It is a vector-space-based machine-learning
method where the goal is to find a decision
boundary between two classes that is maximally
far from any point in the training data (possibly
discounting some points as outliers or noise).
3. LINEARLY SEPARABLE CASE
• If the training data is linearly separable, we can
select two parallel hyperplanes that separate
the two classes of data, so that the distance
between them is as large as possible.
• The region bounded by these two hyperplanes
is called the "margin", and the maximum-
margin hyperplane is the hyperplane that lies
halfway between them.
4.
5. • With a normalized or standardized dataset, these
hyperplanes can be described by the equations:-
Case 1:- w ^T x -b=1 (anything on or above this
boundary is of one class, with label 1)
And
Case 2:- w^T x -b=-1 (anything on or below this
boundary is of the other class, with label −1).
• The distance between these two hyperplanes
is 2|w|,so to maximize the distance between
the planes we want to minimize|w|.
6. • The distance is computed using the distance from a
point to a plane equation. We also have to prevent
data points from falling into the margin, we add the
following constraint: for each i either
w^Tx_i-b>= 1}, if y_i =1,
or
w^Tx_i-b<=-1}, if y_i=-1.
• These constraints state that each data point must lie
on the correct side of the margin. This can be
rewritten as:-
Y_i(w^Tx_i-b)>=1, for all 1<=i<=n.
7. • We can put this together to get the optimization
problem:
"Minimize |w| subject to y_i (w ^Tx _i-b) >=1 for
i=1,……..,n.”
• The w and b that solve this problem determine
our classifier,x→sgn (w ^Tx -b) where sgn(.) is
the sign function.
• An important consequence of this geometric
description is that the max-margin hyperplane is
completely determined by those ͢ x_i that lie
nearest to it. These x _i are called support
vectors.

9. EXTENSION TO THE SVM MODEL
SOFT MARGIN CLASSIFICATION
MULTICLASS SUPPORT VECTOR MACHINE
NONLINEAR SUPPORT VECTOR MACHINE
10. SOFT MARGIN CLASSIFICATION
An additional set of coefficients are
introduced that give the margin wiggle room
in each dimension. These coefficients are
called slack variables.
This increases the complexity of the model as
there are more parameters for the model to fit
to the data to provide this complexity.
A tuning parameter is introduced called simply
C that defines the magnitude of the wiggle
allowed across all dimensions.
11. Real data is messy and connot be separated
perfectly with a hyperplane.
The constrains of maximizing the margin of the
line that separates the classes must be relaxed.
This is called as the soft margin classifier.
This change allows some points in the training
data to violate the separating line.
The C parameters defines the amount of violation
of the margin allowed. A C=0 is no violation and
we are back to the inflexible Maximal-Margin
Classifier .
The larger the value of C the more violations of
the hyperplane are permitted.
12. During the learning of the hyperplane from data,
all training instances that lie within the distance
of the margin will affect the placement of the
hyperplane and are referred to as support
vectors.
C affects the number of instances that are
allowed to fall within the margin. C influences
the number of support vectors used by the
model.
• The smaller the value of C, the more sensitive the algorithm
is to the training data (higher variance and lower bias).
• The larger the value of C, the less sensitive the algorithm is
to the training data (lower variance and higher bias
13. MULTICLASS SUPPORT VECTOR
MACHINE
• SVM doesn’t support multiclass classification
natively. It supports binary classification and
separating data points into two classes.
• For multiclass classification, the same
principle is utilized after breaking down the
multi classification problem into multiple
binary classification problems.
14. • The popular methods which are used to
perform multi-classification on the problem
statements using SVM are as follows:
• One vs One (OVO) approach
• One vs All (OVA) approach
• Directed Acyclic Graph (DAG) approach
15. One vs One (OVO)
• This technique breaks down our multiclass
classification problem into subproblems which are
binary classification problems. So, after this strategy,
we get binary classifiers per each pair of classes. For
final prediction for any input use the concept
of majority voting along with the distance from the
margin as its confidence criterion.
• The major problem with this approach is that we
have to train too many SVMs.
• In the One-to-One approach, we try to find the
hyperplane that separates between every two
classes, neglecting the points of the third class
16. • For example, here Red-Blue line tries to
maximize the separation only between blue
and red points while It has nothing to do with
the green points.
17. One vs All (OVA)
• In this technique to predict the output for new
input, just predict with each of the build SVMs
and then find which one puts the prediction the
farthest into the positive region (behaves as a
confidence criterion for a particular SVM).
• In the One vs All approach, we try to find a
hyperplane to separate the classes. This means
the separation takes all points into account and
then divides them into two groups in which there
is a group for the one class points and the other
group for all other points.
18. • For example, here the Greenline tries to
maximize the gap between green points and
all other points at once.
19. • A single SVM does binary classification and
can differentiate between two classes. So
according to the two above approaches, to
classify the data points from L classes data set.
• In the One vs All approach, the classifier can
use L SVMs.
• In the One vs One approach, the classifier can
use L(L-1)/2 SVMs.
20. Directed Acyclic Graph (DAG)
• This approach is more hierarchical in nature
and it tries to addresses the problems of the
One vs One and One vs All approach.
• This is a graphical approach in which we
group the classes based on some logical
grouping.
21. NONLINEAR SUPPORT VECTOR
MACHINE
• When we cannot separate data with a straight
line we use Non – Linear SVM.
• for which, we have Kernel functions. They
transform non-linear spaces into linear spaces.
• It transforms data into another dimension so that
the data can be classified.
• It transforms two variables x and y into three
variables along with z. Therefore, the data have
plotted from 2-D space to 3-D space. So we can
easily classify the data by drawing the best
hyperplane between them.
22.
23. KERNELS FUNCTIONS
• It is a Mathematical functions for transforming
data.
• It uses some linear algebra.
Example:
K(x, y) = <f(x), f(y)>
• Different SVM algorithms use different types
of kernel functions.
24. • Various kernels available are:-
1. Linear kernel
2. Non linear kernel
3. Radial basis function (RBF)
4. Sigmoid
5. Polynomial
6. Exponential
25. APPLICATION OF SVM IN REAL WORLD
Some common applications of SVM are-
• Face detection
• Text and hypertext categorization
• Classification of images
• Bioinformatics
• Protein fold and remote homology detection
• Handwriting recognition
• Generalized predictive control(GPC)
