How will Cybernetics And Artificial Intelligence build our future?

Reading Time: 4 minutes

We live in a world where what was considered science fiction mere decades ago has become a reality. Global, wireless internet coverage, 3D printed technologies, the Internet of Things powered by AI-based assistants, and, of course, cyborgs, are all part of the reality we live in.

Cyborgs? Yes, those are real. Look at Dr Kevin Warwick. The man can operate lights, switches, and even computers with the power of his mind thanks to a handy chip implant. Neil Harbisson has overcome achromatopsia thanks to an implant that allows the artist to process colours in real-time on a level unachievable by anyone else on the planet. 

If you were to do some research, you’d find out that these pioneers are merely the tip of a cybernetically enhanced iceberg bringing up the real question: if we’ve already come so far, what awaits us in the future?

Cybernetics

Some of the most prominent projects diving into the exploration of cybernetics feel like they were taken from a cyberpunk novel. And yet they are real. More on the matter, they mark what is potentially the future of humankind as a species. 

Full-spectrum vision. Typically, humans believe that the way we “see” the world is the only possible way. Cybernetics engineers would beg to disagree. A simple injection of nanoantenna has proven to give lab mice the superpower of night vision. The experiment taking place in the University of Massachusetts has only recently moved towards practical studies of the effects the antenna have on rodents, but it has already proven itself to be among the first stepping stones towards cybernetically enhanced eyesight. Additional breakthroughs in the field have shown promising results in turning eyes into video cameras, or even development of artificial retinas capable of returning sight to the blind. 

Artificial brain cells. Modern advancements in the niche of cybernetics have already grown neurons – the basic components of a human brain – in laboratory conditions. These cells, artificially raised on an array of electrodes are proving themselves as a superior replacement to the hardware and software controllers we have today. 

More on the matter, scientists are already using brain-computer interfaces in medicine. Most are designed for therapeutic purposes such as the Deep Brain Stimulation designed to aid patients with Parkinson’s disease.

We will be able to use said technology to create connections that operate via the remaining neural signals allowing amputee patients to feel and move their limbs with the power of their mind. In some cases, as it was with Nigel Ackland, some might even go as far as to use the word enhancement when talking about top tier prosthetics.

Enhanced mobility. Stronger, faster, more durable – those are the goals of military-grade exoskeletons for soldiers that are already branching out into the medical niche and serve as prosthetics for amputee victims.  The combination of hardware and AI-based software eliminate the boundaries of human capabilities while minoring the vitals of the wearer in real-time. 

Technopsychics. The University of Minnesota is working on a computer to brain interface capable of remotely piloting drones. The machines can detect the electrical signals transmitted by the brain to control functioning machines in real-time. If you can navigate a quadcopter through an obstacle course using only the power of your mind today, imagine what we’ll be piloting remotely tomorrow. 

Nanorobots. Self-repair, growth, and immunity to diseases will soon be true thanks to a simple infusion of nanobots into your bloodstream. Modern researches explore the idea of developing your blood cell’s little helpers that can be controlled in the cloud from your smartphone!

Artificial Intelligence

As you may have deduced from the examples above, the advancements in the cybernetics niche are directly related to the progress we make with Artificial Intelligence or Machine Learning technologies. 

We need the software capable of driving the hardware to its limits if we are to dive deeper into cyborg technology. Artificial Intelligence is supposed to become the bridge between the man and the machine according to prominent research such as Shimon Whiteson and Yaky Matsuka. These scientists are exploring new ways AI can help amputee patients to operate their robotic prosthetics. 

Furthermore, AI is expected to take control of machines doing sensitive work in hazardous areas. According to BBC, we already have smart bots capable of defusing bombs and mines yet they still require a human controlling them. In the future, these drones (and many more, responsible for such challenging tasks as toxic waste disposal, deep-sea exploration, and volcanic activity studies, etc.) will be powered purely by algorithms. 

Lastly, machines are expected to analyze and understand colossal volumes of data. According to Stuart Russell, The combination of AI-powered algorithms and free access to Big Data can identify new, unexpected patterns we’ll be able to use to mathematically predict future events or solve global challenges like climate change. 

What a time to be alive!

2. What is the use of Statistics in Data Science?

Ans. Statistics provides tools and methods to identify patterns and structures in data to provide a deeper insight into it. Serves a great role in data acquisition, exploration, analysis, and validation. It plays a really powerful role in Data Science.

 

3. What is the importance of Data Cleansing?

Ans. As the name suggests, data cleansing is a process of removing or updating the information that is incorrect, incomplete, duplicated, irrelevant, or formatted improperly. It is very important to improve the quality of data and hence the accuracy and productivity of the processes and organization as a whole.

 

4. What is a Linear Regression?

The linear regression equation is a one-degree equation of the form Y = mX + C and is used when the response variable is continuous in nature for example height, weight, and the number of hours. It can be a simple linear regression if it involves continuous dependent variable with one independent variable and a multiple linear regression if it has multiple independent variables. 

 

5. What is logistic regression?

Ans. When it comes to logistic regression, the outcome, also called the dependent variable has a limited number of possible values and is categorical in nature. For example, yes/no or true/false etc. The equation for this method is of the form Y = eX + e – X

 

6. Explain Normal Distribution

Ans. Normal Distribution is also called the Gaussian Distribution. It has the following characteristics:

a. The mean, median, and mode of the distribution coincide

b. The distribution has a bell-shaped curve

c. The total area under the curve is 1

d. Exactly half of the values are to the right of the centre, and the other half to the left of the centre

 

7. Mention some drawbacks of the linear model

Ans. Here a few drawbacks of the linear model:

a. The assumption regarding the linearity of the errors

b. It is not usable for binary outcomes or count outcome

c. It can’t solve certain overfitting problems

 

8. Which one would you choose for text analysis, R or Python?

Ans. Python would be a better choice for text analysis as it has the Pandas library to facilitate easy to use data structures and high-performance data analysis tools. However, depending on the complexity of data one could use either which suits best.

 

9. What steps do you follow while making a decision tree?

Ans. The steps involved in making a decision tree are:

a. Pick up the complete data set as input

b. Identify a split that would maximize the separation of the classes

c. Apply this split to input data

d. Re-apply steps ‘a’ and ‘b’ to the data that has been divided 

e. Stop when a stopping criterion is met

f. Clean up the tree by pruning

10. What is Cross-Validation? 

Ans. It is a model validation technique to asses how the outcomes of a statistical analysis will infer to an independent data set. It is majorly used where prediction is the goal and one needs to estimate the performance accuracy of a predictive model in practice.

The goal here is to define a data-set for testing a model in its training phase and limit overfitting and underfitting issues. The validation and the training set is to be drawn from the same distribution yo avoid making things worse.

 

11. Mention the types of biases that occur during sampling?

Ans. The three types of biases that occur during sampling are:

a. Self-Selection Bias

b. Under coverage bias

c. Survivorship Bias

 

12. Explain the Law of Large Numbers

Ans. The ‘Law of Large Numbers’ states that if an experiment is repeated independently a large number of times, the average of the individual results is close to the expected value. It also states that the sample variance and standard deviation also converge towards the expected value.

 

13. What is the importance of A/B testing

Ans. The goal of A/B testing is to pick the best variant among two hypotheses, the use cases of this kind of testing could be a web page or application responsiveness, landing page redesign, banner testing, marketing campaign performance etc. 

The first step is to confirm a conversion goal, and then statistical analysis is used to understand which alternative performs better for the given conversion goal.

 

14. What are over-fitting and under-fitting?

Ans. In the case of over-fitting, a statistical model fails to depict the underlying relationship and describes the random error and or noise instead. It occurs when the model is extremely complex with too many parameters as compared to the number of observations. An overfit model will have poor predictive performance because it overreacts to minor fluctuations in the training data.

In the case of underfitting, the machine learning algorithm or the statistical model fails to capture the underlying trend in the data. It occurs when trying to fit a linear model to non-linear data. It also has poor predictive performance.

 

15. Explain Eigenvectors and Eigenvalues

Ans. Eigenvectors depict the direction in which a linear transformation moves and acts by compressing, flipping, or stretching. They are used to understand linear transformations and are generally calculated for a correlation or covariance matrix. 

The eigenvalue is the strength of the transformation in the direction of the eigenvector.

What are the career prospects for a DevOps Engineer?

Reading Time: 4 minutes

The DevOps domain is getting attention for its role in building better communication, collaboration, and agility between software development and operations teams. The role of a DevOps engineer is hard to understand because it is the product of a dynamic workforce which has not yet stopped evolving.

DevOps is a software development strategy that bridges the gap between developers and their IT counterparts. It is a practice that aims to merge software development, quality assurance, and deployment and integration operations into a consolidated and continuous set of processes.

DevOps is a natural extension for Agile and other continuous delivery approaches. With DevOps, organizations can release tiny features quickly and incorporate the feedback they receive from stakeholders rapidly.

It’s good to note that DevOps is not merely a set of actions, but more a philosophy that facilitates cross-functional team communication.

What is DevOps Engineer?

DevOps engineers work with the software developers and IT professionals to track code releases. They are the people who wear multiple hats – software development, deployment, network operations, and system admins. Teamwork stands at the core of a DevOps practice and the overall success of a process depends on the same.

As such, DevOps engineers are expected to have a thorough understanding of various concepts such as version control, serverless computing, integration, testing, and deployment. 

The role of a DevOps engineer is formed out of the need of businesses to get hold of their cloud infrastructure in a hybrid environment. Organizations who work with DevOps spend relatively less time on managing configurations, deploying applications, and making tweaks and updates.

The Skills Needed for a Successful DevOps Engineering Career

According to Puppet, the most critical skills for a DevOps engineer are:

– Coding and scripting

Therefore, a DevOps engineer must be aware of the various development tools which are used by software developers to write new code or enhance the existing code.

A DevOps engineer needs to collaborate with the team to handle challenges that spring up in the coding or scripting part including libraries and SDKs. A DevOps engineer handles code that needs to fit across multi-tenant environments, including the cloud.

Here are the roles and responsibilities of a DevOps engineer, in a nutshell:

– Apply cloud computing skills to deploy upgrades and bug fixes across AWS, Azure, or GCP.

– Design, develop, and implement software integrations on the basis of user feedback and reviews.

– Troubleshoot and resolve production issues and coordinate with the development team to simplify and streamline code deployment.

– Implement automation frameworks and tools – CI/CD pipelines.

– Manage the IT infrastructure, which comprises of the network, software, hardware, storage, virtual and remote assets, and control over data cloud storage.

– Continuously monitor software environments for any loopholes.

– Analyze code continuously and communicate detailed feedback to software development teams to ensure improvement in software and timely completion of projects.

– Collaborate with team members to improve engineering tools, systems, procedures, and security arrangements.

– Optimize and enhance the business’ computing architecture.

– Conduct system checks for security, availability, and performance.

– Develop and maintain troubleshooting documentation to keep up with past and future fixes.

 

Apart from these explicit set of actions, DevOps engineers are also expected to follow the essential DevOps principles:

– Culture inherent in the need for communication, collaboration, and technical processes and tools.

– Automation of processes

– Measurement of the Key Performance Indicators

– Sharing feedback, knowledge, and best practices.

How Much Does a DevOps Engineer Earn?

A career transition can be a daunting experience for many. But given the right direction, learning, and support, it is more like a cakewalk. That’s why here at Great Learning, we strive to provide the right learning, practical exposure, and complete career support. 

What has your professional journey been like?

I completed my graduation in Electronics and Communications Engineering from Amrita College, Bangalore. Then I moved to the USA to pursue my Masters in Electrical Engineering from the University of Missouri, Kansas-City in the year 2014. I got placed in Reliable Software Resources as a QA Tester and worked until May 2017. I will be joining Mercedes Benz very soon as a Data Analyst.

How did you develop an interest in Data Science? Why did you choose GL to pursue it?

Previously, I was working as a manual tester for a Consulting firm. The job profile involved manual testing for a project of Banking. The role was very limited and monotonous, so I decided not to go deeper into testing. I left my job and moved back to India. As I was from a non-programming background, I was very sceptical to get into coding and related fields. I was looking into various technologies and was suggested by a friend to consider Data Science as an option. I attended many seminars and workshops on Data Science organized by various companies. I developed an interest in this field and was looking for a classroom course. On the recommendation of the same friend, I joined Great learning to pursue PGP-DSE.

Coming from a non-programming background, was it difficult for you to understand the subjects?

Not at all. As most of the students in the batch were from the non-IT background, the course is designed keeping them in mind. The faculties ensured that the basics were covered. I understood that the course is based on Logics, so I slowly developed pace and contrary to my presumptions, I didn’t find it difficult. The faculty put in a lot of time and attention towards us and even repeated the sessions whenever required.

How was your experience of the academic and career support given by GL?

The team was always available, especially Akhila as she helped us thoroughly in preparing for the interviews and gave regular suggestions and feedback for us to improve at the same. Whenever we had any issues, Akhila and the team resolved them at priority.

With Career support, I got to interview with many companies like CTS, Mercedes, etc. Based on my experience, I realized that the curriculum is self-sufficient to crack any interview. The entire course is designed in a way to help us understand the concepts, crack interviews, and guide during the projects. 

What did you like the most in the program?

We were assigned mini projects on the completion of every topic. This gave a lot of hands-on experience of every topic in terms of understanding and its practical application. This hands-on experience on mini projects gave me a lot of confidence and helped me in exams as it gave a recap of all that we had learned in the course. After the completion of the course, during the capstone project, there were many remedial sessions to clear doubts. 

Share your experience of the interview with Mercedes.

The interview was organized by GL at Mercedes’s Bangalore office. The interview included a total of 3 rounds; 2-Technical and 1-HR. The first round included questions based on whatever I had mentioned in my resume and basic questions over Coding, ML, SQL, etc. 2nd round involved questions related to the Business aspect. The final round was an HR round, where they gave me a confirmation after the interview.

Any advice to aspirants who wish to take this course?

They should be confident in sharing what they know and admit to what they don’t know. Give your 100% to every interview thinking that this is the last opportunity as there is a huge competition in the market.

What has your professional background been?

I completed my Graduation in Electrical, Electronics & Communications Engineering in 2018 from Belagavi, Karnataka. I then took a course in Data Science at Great Learning, Bangalore and currently, I am working in Ugam Solutions as an Associate Analyst.

How did you develop an interest in Data Science?

I finished my graduation with 58% aggregate score. With this score, I was not eligible to attend interviews for any good role or company. I understood the need to upskill myself as my father suggested me to read about Data Science which has created a lot of buzz. After researching online, I developed an interest in it and got fascinated with what this field can do.

Why did you choose GL to pursue a course in Data Science Engineering?

After viewing the scope and growth opportunities, I immediately started to search for courses. But to choose the best out of them was a task in itself. All I wanted was to take a classroom program as for a fresher it was better compared to online training. I visited GL’s website for weeks and saw it was regularly updated with relevant data and testimonials. I checked the reviews on Google and LinkedIn as well. Finally, I looked at the faculty profiles on LinkedIn and saw their experience. I understood that GL is the best institute in India to study Data Science, so I took up the course here. 

What did you like the most in the program?

There were many things that I loved about the program.

  1. The Faculty: Since I looked at the LinkedIn profiles of almost all the teaching professionals, I got to know that they all were Industry experts and had a great experience in their respective fields. When I enrolled myself for the course, I was surprised to see how grounded and friendly they were. Also, they taught us everything from scratch. 
  2. Course-Curriculum: The course is well designed and well structured. The curriculum is exhaustive and gave me a good understanding of the domain. The course includes what is needed by the industry and everything is accommodated in the syllabus.
  3. Career Assistance: I got to sit on campus drive of 7 companies and got shortlisted in all of them. Apart from this, the CV reviews and Mock Interviews helped me develop confidence and crack interviews. Also, they organized Bootcamps for the students and helped us in all aspects. There were ample opportunities and it got us placed.

Overall it was a nice experience as I got good friends and faculty with whom I learned a lot and I am still in touch with them. I feel very grateful to GL, that helped me to kick start my career.

Being from a non-programming background, did you face any issues with the course or the transition?

Initially, it was very hard for me to adjust to the syllabus as I was not at all familiar with Coding or programming. The first week of the course started with Python, which was a new thing for me. Here, I would like to mention that the teaching faculty boosted my confidence by mentioning that “It is not rocket science and is easy to learn”. After the EDA session, I felt self-motivated and realised that irrespective of any branch, one can achieve success in their ventures. Slowly things started to fall in place. I was in regular sync with sessions, and the regular exams and quizzes kept us in constant touch of the topics. In the end, everything was good and great.

Share your experience of interviewing with Ugam?

I had 4 rounds of the interview; An SQL Test of 30 minutes duration, followed by a Case Study of 30 minutes duration again, a Technical round and finally an interview session with Vice President and HR. The technical round involved questions around my Project mentioned in the Resume and general technical questions to check my understanding of algorithms. With the VP, the interview was to check how my understanding can contribute to the Analytics team of Ugam and general questions from the HR. After the interview, I received a job confirmation from them. 

Any advice to our future aspirants of this course.

I would like to suggest to prepare well on Stats and SQL. The material is self-sufficient and includes in-depth content and curriculum. The placement assistance is superb and helps everyone in getting placed. So there is no need to panic for anything. Also, focus on your project as all my interview questions revolved around my Capstone Project.
