1. Hot Topics in Machine Learning for
Research and Thesis

2.  Machine Learning and its subsequent fields have
undergone tremendous growth in the past few
years. It has a number of potential applications
and is being used in different fields. A lot of
research work is going on in this field. There has
been a lot of buzz around this field in the recent
times. It is the major application of Artificial
Intelligence. Algorithms are a major component of
Machine Learning. One should have a complete
understanding of these algorithms before doing
research on different topics in Machine Learning.
There are various hot research topics in
machine learning for M.Tech thesis and Ph.D.
research.

3. List of hot topics in Machine Learning
 Deep Learning
 Human-computer interaction
 Genetic Algorithm
 Image Annotation
 Reinforcement Learning
 Natural Language Processing
 Supervised Learning
 Unsupervised Learning
 Support Vector Machines(SVMs)
 Sentiment Analysis

4. Deep Learning
 Deep Learning is a sub-field of Machine Learning
or we can say it is an advanced version of
Machine Learning. Deep Learning can also be
referred to as deep structure learning or
hierarchical learning.
 It is one of the hot topics in machine learning for
master’s thesis and research. The concept of
deep learning is being used by big companies like
Google, Amazon to increase their productivity and
sale rate

6. Human-computer Interaction
 Human-computer interaction or HCI is the study
of human and computer activities and how they
interact with each other. It is a very good field for
research in machine learning. There are different
ways in which humans interact with computers
and HCI deals with the study of this interaction.
To facilitate this interaction, an interface is
required between humans and computers.
 A graphical user interface is one such example of
the interface used by desktop applications and
internet browsers. Similarly, voice user
interfaces(VUI) are used for speech recognition.

8. Genetic Algorithm
 The concept of Genetic Algorithm is based on the
principle of Genetics and Natural Selection and is
a search-based optimization technique used to
find optimal solutions to complex problems. It is
another good topic in machine learning for thesis
and research. It is the most efficient tool to solve
difficult problems referred to as NP-Hard
problems.

10. Image Annotation
 Image Annotation is a process in which a caption
or keyword is assigned to a digital image
automatically. It finds its application in image
retrieval systems to locate images from the
database. Machine Learning methods and
algorithms are applied to Automatic Image
Annotation. Clustering and classification are the
most commonly used methods in the process of
image annotation.

11. Reinforcement Learning
 Reinforcement Learning is a type of machine
learning algorithm in which an agent learns how
to behave in an environment by interacting with
that environment. A lot of research has been done
in this area of machine learning in the recent
times. It mostly finds its application in gaming and
robotics. The approach of this algorithm is
different from other machine learning algorithms
which are supervised learning and unsupervised
learning.

12. Natural Language Processing
 Natural Language Processing or NLP is a branch
of Artificial Intelligence using which computers are
made to understand, manipulate, and interpret
human language. It aims to fill the space between
human communication and computer
understanding. It is another good topic in
machine learning for thesis and research. It uses
the concept of machine learning and deep
learning for complete interaction between
humans and computers.

13. Supervised Learning
 It is a type of machine learning algorithm in which
both input and output data is provided and the
output data is mapped to the input through a
mapping function. In other words, supervised
learning is a type of machine learning algorithm
that uses training datasets for making decisions.
There are two types of algorithms in supervised
learning which are:
1. Classification
2. Regression

14. Unsupervised Learning
 Unsupervised Learning is a type of machine
learning algorithm to find hidden patterns and
underlying data structures. The inferences are
drawn by this algorithm from the datasets
containing the input data. Cluster Analysis is the
most commonly used method in unsupervised
learning. General clustering algorithms in
unsupervised learning are:
 Hierarchical Clustering
 k-Means Clustering
 Self-organizing maps
 Hidden Markov Models
 Gaussian mixture models

15. Support Vector Machines(SVMs)
 Support Vector Machines or SVMs are one of the
most important machine learning algorithms. The
purpose of this algorithm is to analyze the data
used for classification and regression analysis. As
compared to other algorithms, the concepts of
SVM are relatively simple. Using kernel trick,
SVMs can perform non-linear classification. In
this algorithm, each data item is plotted as a point
in n-dimensional space where n is the number of
features. After that, classification is performed on
data items. A hyperplane will be found that will
divide the datasets into two different classes.

16. Sentiment Analysis
 Sentiment Analysis is also known as opinion
mining and is a process to determine whether the
attitude of an individual towards a product or topic
is positive, negative 0r neutral expressed in the
form of text. It is another good research topic in
machine learning for thesis and research. It
uses the concept of natural language processing,
machine learning, computational linguistics, and
bioinformatics to extract essential information. It is
mainly used in case of social media
monitoring. Sentiment Analysis is crucial such
that it helps to find what a customer thinks of a
particular brand.

17. These are the hot topics in Machine Learning for thesis
and research although there are various other topics
also. Machine Learning is one of the trending fields for
the thesis in computer science.
