DEEP LEARNING SERIES- PART 6
The previous article was about the procedure to develop a deep learning network and introduction to CNN. This article concentrates on the process of convolution which is the process of taking in two images and doing a transformation to produce an output image. This process is common in mathematics and signals analysis also. The CNN’s are mainly used to work with images.
In the CNN partial connection is observed. Hence all the neurons are not connected to those in the next layer. So the number of parameters reduces leading to lesser computations.

Sample connection is seen in CNN.
Convolution in mathematics refers to the process of combining two different functions. With respect to CNN, convolution occurs between the image and the filter or kernel. Convolution itself is one of the processes done on the image.
Here also the operation is mathematical. It is a kind of operation on two vectors. The input image gets converted into a vector based on colour and dimension. The kernel or filter is a predefined vector with fixed values to perform various functions onto the image.
Process of convolution
The kernel or filter is chosen in order of 1*1, 3*3, 5*5, 7*7, and so on. The given filter vector slides over the image and performs dot product over the image vector and produces an output vector with the result of each 3*3 dot product over the 7*7 vector.
A 3*3 kernel slides over the 7*7 input vector to produce a 5*5 output image vector. The reason for the reduction in the dimension is that the kernel has to do dot product operation on the input vector-only with the same dimension. I.e. the kernel slides for every three rows in the seven rows. The kernel must perfectly fit into the input vector. All the cells in the kernel must superimpose onto the vector. No cells must be left open. There are only 5 ways to keep a 3-row filter in a 7-row vector.

This pictorial representation can help to understand even better. These colors might seem confusing, but follow these steps to analyze them.
- View at the first row.
- Analyse and number the different colours used in that row
- Each colour represents a 3*3 kernel.
- In the first row the different colours are red, orange, light green, dark green and blue.
- They count up to five.
- Hence there are five ways to keep a 3 row filter over a 7 row vector.
- Repeat this analysis for all rows
- 35 different colours will be used. The math is that in each row there will be 5 combinations. For 7 rows there will be 35 combinations.
- The colour does not go beyond the 7 rows signifying that kernel cannot go beyond the dimension of input vector.
These are the 35 different ways to keep a 3*3 filter over a 7*7 image vector. From this diagram, we can analyse each row has five different colours. All the nine cells in the kernel must fit inside the vector. This is the reason for the reduction in the dimension of output vector.

Procedure to implement convolution
- Take the input image with given dimensions.
- Flatten it into 1-D vector. This is the input vector whose values represent the colour of a pixel in the image.
- Decide the dimension, quantity and values for filter. The value in a filter is based on the function needed like blurring, fadening, sharpening etc. the quantity and dimension is determined by the user.
- Take the filter and keep it over the input vector from the first cell. Assume a 3*3 filter kept over a 7*7 vector.
- Perform the following computations on them.
5a. take the values in the first cell of the filter and the vector.
5b. multiply them.
5c. take the values in the second cell of the filter and the vector.
5d. multiply them.
5e. repeat the procedure till the last cell.
5f. take the sum for all the nine values.
- Place this value in the output vector.
- Using the formula mentioned later, find the dimensions of the output vector.

DEEP LEARNING SERIES- PART 5
The previous article was on algorithm and hyper-parameter tuning. This article is about the general steps for building a deep learning model and also the steps to improve its accuracy along with the second type of network known as CNN.
General procedure to build an AI machine
- Obtain the data in the form of excel sheets, csv (comma separated variables) or image datasets.
- Perform some pre-processing onto the data like normalisation, binarisation etc. (apply principles of statistics)
- Split the given data into training data and testing data. Give more preference to training data since more training can give better accuracy. Standard train test split ratio is 75:25.
- Define the class for the model. Class includes the initialisation, network architecture, regularisation, activation functions, loss function, learning algorithm and prediction.
- Plot the loss function and interpret the results.
- Compute the accuracy for both training and testing data and check onto the steps to improve it.
Steps to improve the accuracy
- Increase the training and testing data. More data can increase the accuracy since the machine learns better.
- Reduce the learning rate. High learning rate often affects the loss plot and accuracy.
- Increase the number of iterations (epochs). Training for more epochs can increase the accuracy
- Hyper parameter tuning. One of the efficient methods to improve the accuracy.
- Pre-processing of data. It becomes hard for the machine to work on data with different ranges. Hence it is recommended to standardise the data within a range of 0 to 1 for easy working.
These are some of the processes used to construct a network. Only basics have been provided on the concepts and it is recommended to learn more about these concepts.
Implementation of FFN in detecting OSTEOARTHRITIS (OA)
Advancements in the detection of OA have occurred through AI. Technology has developed where machines are created to detect OA using the X-ray images from the patient. Since the input given is in the form of images, optimum performance can be obtained using CNN’s. Since the output is binary, the task is binary classification. A combination of CNN and FFN is used. CNN handles feature extraction i.e. converting the image into a form that is accepted by the FFN without changing the values. FFN is used to classify the image into two classes.
CNN-convolutional neural network
The convolutional neural network mainly works on image data. It is used for feature extraction from the image. This is a partially connected neural network. Image can be interpreted by us but not by machines. Hence they interpret images as a vector whose values represent the color intensity of the image. Every color can be expressed as a vector of 3-D known as RGB- Red Green Blue. The size of the vector is equal to the dimensions of the image.

This type of input is fed into the CNN. There are several processing done to the image before classifying it. The combination of CNN and FNN serves a purpose for image classification.
Problems are seen in using FFN for image
- We have seen earlier that the gradients are chain rule of gradient at different layers. For image data, large number of layers in order of thousands may require. It can result in millions of parameters. It is very tedious to find the gradient for the millions of these parameters.
- Using FFN for image data can often overfit the data. This may be due to the large layers and large number of parameters.
The CNN can overcome the problems seen in FFN.

History & Law

“History and law are two sides of a polished mirror”. As we read it, that is there any relation of history with the law, then suddenly it strikes our mind that these two are different subjects because in India students mostly take topics in relation with the subjects they are studying. But when we think beyond, the subject we get to know that history and law are interrelated. Laws are influenced by events in history. The events which have happened before and what their outcomes were and what things can be changed for the better. In taking all these points in mind, laws are made. We take a lesson from our history to make laws.
History is also related to law. As we read the incidents in our history, they are somehow related to the laws which existed at those times. The British laws which are still followed now from our history are Indian penal code,1860; the transfer of property act, 1882; the foreigner’s act, 1946; Income tax act, 1961; Indian evidence act,1872; Indian police act,1861; etc.
The goods and the bads all somehow share a relationship with the laws and rules. The movements which changed the life of many countries also took place because of the heinous laws in countries like the French revolution, the American civil war, the National movements in India, and many more. All are related to laws that became unbearable torture on the victims. One can study the connection between law and history in comparative law. Comparison of laws of different time scales can be done. Law is a process that makes the public civilized, abides by norms that are set by society from time to time. Hence, the law is continuity in search of humanity and civility.
Now the question that arises is: “Which part of history is relevant in today’s time“? According to my, contemporary history is most important in the present time. Contemporary history includes the span of historical events starting from 1945. These events are most relevant to the present time scenario. Many historians describe the early modern period as the time frame between 1500 and 1800. This period mainly follows the late middle-age period. Further, it is marked by the initial European colonies, the beginning of recognizable nation-states as well as the rise of strong centralized government.
Contemporary history helps in strengthening the cultural identity of a nation. This is because when we learn about the cultural heritage of our race or religion, we engulf ourselves in an abundance of information, which often depicts the decisions our ancestors made or the traditions that have been carried down the generations. These define who we are and why we exist in our society.
History well told is beautiful. Many of the historians who most appeal to the general reading public, know the importance of dramatic and skillful writing as well as of accuracy. History is very important because it helps us to understand the present. If we will listen to what history has to say, we can come to a sound understanding of the past that will tell us much about the problems we now face. If we refuse to listen to history, we will find ourselves fabricating a past that reinforces our understanding of current problems.
To conclude, George Mosse once said, “What man is, the only history tells.” History is interlinked with law. With truly reading, one can have a holistic view of the idea of the concept. In my view, contemporary history is more relevant in today’s time. The study of it is still relevant albeit the uncertainty of today’s world. As the saying goes, “With age comes wisdom“, is a true reminder of the experience one gains with the passage of times (which is history).

An unexamined life is not worth living
by Shashikant Nishant Sharma
(Photo: Motivation Mentalist)
Well said by
Socrates.
An
unexamined human life is deprived of the meaning and purpose of existence. The
ability to introspect removes the individualistic absurdity by invoking a
commitment to moral integrity and social solidarity.
Just like a seed
needs soil, sunlight and water for its germination, human life needs
introspection and examination for its growth. A greater understanding of the
experiences gained in the life at any particular time, enriches one’s
engagement with self and the universe.
Mahatma Gandhi’s
examination of self through his autobiography, “My experiments with
truth”, highlights the significance of reflection on life. Mahatma Gandhi
was not only able to map his weaknesses and vulnerabilities through the
examination, but was also able to question his prejudices and understand his
strength as a human being.
This very ability
to reflect on life adds more depth to the character of Arjun in Mahabharat than
most of the other characters. Instead of following the norms and fighting with
his clan, Arjun questions the meaninglessness of the war and the purpose of his
life.
The fast-changing
societies and consumerist culture in the contemporary world leave less time for
human beings to examine and think about the changes. Adaptation to changes have
become automatic and unquestionable.
The quotation has
strong relevance in the present times where human beings are burdened with the
histories of war, colonisation, nationalisation, erosion of morality in the
scientific and technological advancements and the sense of spiritual
uprootedness.
It is in these
times that one needs to dwell deeper into the conscience to find the purpose of
existence and engage in a more meaningful manner with the society.
THE FIGHT AGAINST CHILD TRAFFICKING
Child trafficking alludes to the abuse of girls and boys, essentially for labor work and sexual exploitation. Children account for 27% of all the illegal exploitation victims around the world, and two out of each three child victims are girls. Some of the time sold by a relative or an associate, in some cases baited by bogus guarantees of education and a “superior” life.

The reality is that they take advantage of children. They are held in slave-like conditions without sufficient food, haven or clothing, and are regularly seriously manhandled and cut off from all contact with their families. Every country on the planet is influenced by human trafficking, and subsequently, kids are compelled to exit school, hazard their lives and are denied of what each child deserves ,a better future.
We can stop this by supporting unprivileged children who are denied of legitimate education, health and shelter. It’s a child right to get legitimate education, heath and shelter fundamentally a superior living. We can do this by interfacing with NGOs which work in improvement of kids’ lives. We can donate cash, garments and different accomplices to them. Also strict action should be taken against those who are involved in this vicious crime. Children are future of a country if they are not safe then a country will never develop.

ATTITUDES AND JOB SATISFACTION
ATTITUDES AND JOB SATISFACTION
Attitudes are evaluative statements they may either be favorable or unfavorable. It is concerned with the objects, people or events. They reflect how we feel about something which finally leads to everything because that an Attitude. They are complex, to be more estimable it is considered to be as the fundamental properties or components.
The attitude towards the job is all what defines us. Typically, researchers assume that attitudes have three components: COGNITIVE, AFFECTIVE, BEHAVIORAL. Cognitive component is the opinion or belief with a particular segment of an attitude. Affective component is the motion or feeling segment of an attitude. Behavioral component is an intention to behave in a certain way forward or toward someone or something.
When it comes to Organizations, attitudes are important. When we think Job is important, we need to change our attitude, according to the sequence with the knowledge development. Performance can be enriched when one commits towards the job.
JOB SATISFACTION
We as human beings have thousand of attitudes, but Organizational behavior focuses on a very limited number of that form positive or negative evaluations that employees hold about their work environment. Much of the research has looked at three attitudes Job Satisfaction, Job involvement and Organizational commitment. Other important attitudes include perceived organizational support and employee engagement.
The job satisfaction is said to be a positive feeling about evaluating job characteristics while a person with the negative feeling shows less job satisfaction. Employees with high job involvement strategy, identify, with care about the kind of work they do, they enjoy themselves.
An employees’ asset is the true satisfaction as if it were separate from life satisfaction, but they may be more related to think. Life satisfaction decreases when people become unemployed, according to research in Germany, and not just because of the loss of income. Research in Europe says that job satisfaction is positively correlated with the life satisfaction, and your attitudes and experiences in life spill over into your job approaches and experiences.
HOW CAN I MAKE MY JOB BETTER?
- You can work on your attitude to either improve your experience or find a positive perspective.
- Write down everything you hate about your job, but wait for a few days off so that you can get a more objective view important.
- Be specific, Think about the environment, the people and the work separately, find something positive even if it’s just the coffee in the break room.
- Job satisfaction is generally more strongly related to how interesting you work is than it is to other factors.
- Read your lists aloud to a few trusted friends.
- Decide what to do, you will be getting a solution.
