How Machine Learning Affects Everyday Life?

Many people are familiar with machine learning from shopping on the internet and being served ads related to their purchase. This happens because recommendation engines use machine learning to personalize online ad delivery in almost real time. Beyond personalized marketing, other common machine learning use cases include fraud detection, spam filtering, network security threat detection, predictive maintenance and building news feeds.

Now lets brief about Machine Learning

Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.

The process of learning begins with observations or data, such as examples, direct experience, or instruction, in order to look for patterns in data and make better decisions in the future based on the examples that we provide. The primary aim is to allow the computers learn automatically without human intervention or assistance and adjust actions accordingly.

And, the good news is, Latest technology is advancing consistently and revolutionizing every facet of our routines. Humans had their first brush-up with Machine Learning when voice-controlled personal assistants — Amazon’s Echo and Alexa — were launched. These devices are a new normal with the trend of smart homes picking up. Driverless cars, which were a quintessential sci-fi fantasy, aren’t something of the far-off future now. These new-age vehicles, aimed at cutting down human labor, are tested across the world for their utility benefits.

Let’s dive in how Machine Learning is revolutionizing our lives.

1. Health

Machine Learning can empower surgical robots to help doctors in medical procedures while ensuring minimal invasion and high precision. This achievement can improve the success rates of surgical procedures and accelerate turnaround time with cost benefits. In the context of healthcare, ML can be a critical enabler to efficient diagnosis, research, and treatment, thereby underlining the holistic transformation of the sector.

From administration, record-keeping to fully fledged diagnosis and treatments, ML has the capability to analyze the crisis at hand and compare it with numerous other scenarios for the right treatment and procedure. This comparison saves time and paves a strategic path for the decisive medical approach.

2. Transportation

Today’s transportation industry is highly influenced by Machine Learning. The technology has been instrumental in eradicating the threat posed by reckless driving through the deployment of sensory management and automation. This has intelligized vehicles to understand the surrounding parameters and take precautionary action whenever required to ensure passenger safety.

China is testing driverless buses for its city while Google and Rolls Royce have collaborated to design and launch the world’s first self-driving ship by 2020. The ship will be leveraging Google’s Cloud Machine Learning Engine to understand the sea and objects surrounding it. This will enable the remote controlling of the vessel and end up reducing the resources involved in the transportation.

Beyond vehicles, Machine Learning can soon by deployed for traffic management and preventing traffic congestions on roads. China and Singapore, at the moment, are leading the innovation and creating algorithms that can help drivers choose routes cleared off traffic.

3. BFSI — Banking and Financial Service Industry

Several banks and financial institutions are using ML-based complex algorithms to analyze and predict loan risks and assess the quality of the application. Therefore, reinforcing them to take informed decisions. It’s also helping in the detection of frauds and scams via analytics.

The otherwise traditional industry is favoring Machine Learning to mitigate its transformational bottlenecks and create better user engagement for the stakeholders, including the customers. Voice Recognition, Chatbots, and Predictive Analysis are helping bridge the gap between financial establishments and potential customers. Today, customers can contact a business anytime around the day and rest assured of instant, real-time replies from Chatbots. This saves time as well as improves the customer experience for the organizations.

4. Education

It’s true that teachers cannot be replaced by bots, but they sure can be assisted by the diversity. Machine Learning can provide to their methods of teaching and education on a whole. ML capabilities are being used to assess the child’s academic understanding, analyze the way he/she perceives knowledge, and create a customized academic plan that can help focus on the wholesome attribute of that specific student.

The algorithms analyze test results and create a unique grading system that can free up the teachers’ time and help refine the education modules for children. Not to mention, ML can be extremely helpful for students with disabilities and learning gaps.

ML, in addition to teaching, is simplifying administrative duties. It helps educational institutions create an organized means of administering students and staff via its automated responses, customized software and more. It’s all about breaking down the processes and making organizing an institution less of a burden.

5. Law

Lawyers remain busy. So, automating their day-to-day activities can free them from the redundant tasks and help them focus on creating liable solutions to the cases at hand.

Machine Learning brings forth this automation and adds a new twist to the otherwise conventional industry. It augments documents and their processing. It also analyzes them for proofs and research, which can help the lawyers extract the relevant information without having to expend time in pouring over books and legal documents. They can also help systemize the operational tasks, such as staying abreast with the hearings and keeping note of the impending dates.

ML can strategize how lawyers review their cases and hopefully, can speed up the cases that otherwise take months and years to resolve.

Linux Careers

Linux Careers – The Future


Linux careers offers plenty of possibilities. At the time of this article, a simple search of ‘Linux’ on yields nearly 72,000 jobs with 52,000 of them being recently posted. Clearly, Linux is a space where a good, solid long term career is possible. But there are some things you should know before you decide to make the leap.

Recently I had the opportunity to sit down with two long time Linux system administrators. These pros have been in the trenches for many years and shared their expertise with me. I then took their thoughts and added it to my list of “career truths” that I was already aware of and decided to share the details here.

Who should consider Linux IT as a career?

So if you’re thinking Linux IT is a good match for you, consider the following:

  1. Do you enjoy learning new things? Linux IT is constantly evolving filled with wonderful discoveries and new technologies. But this isn’t a career path where you only learn about one thing and that’s it. The learning never ends.
  2. Are you well suited to troubleshooting? This is a key asset that I think escapes many newcomers entering any IT field. Not everything works like it should and despite your best efforts, you may be spending a significant amount of time troubleshooting why a server is crashing or one of your scripts isn’t running as it should.
  3. Can you do your job effectively even when stressed? This is one thing I’d love to see more Human Resource Managers (HR) ask new recruits. While there are exceptions, many areas of Linux IT is high stress. If your job involves critical data availability and/or working with stubborn end users who refuse to recognize best practices, you’re going to be stressed at times. You may need to be the type of person who can keep it together and persevere through some high stress situations.

If you can answer yes to all of the above and also have an aptitude for technology, then Linux IT may be a career path worth pursuing.

Preparing for your first Linux IT job

When you’re fresh out of College, the first temptation is to immediately start racking up various Linux and networking certifications. On the surface, this is fine. However you must pursue honing your Linux skills first.

This means learning basic Linux commands and functions to the point where you can utilize tools like sed, grep, cron, and awk. Master these, perhaps even learn a bit of shell scripting while you’re at it.

Being able to automate basic administrator tasks is actually very important and will demonstrate you’re the right person for a potential job. During your introduction to these tools, bundle this with a “Linux server” that you’re managing. I would start with this set of Linux tutorials.

Some newbies looking to pursue this career path may be tempted to immediately jump into advanced networking, visualization and container management. I advice each of those individuals to start with the links above first, master them and then move onto more advanced Linux tools and technologies.

Once you have a solid handle on your skills, I recommend making a name for yourself before seeking out your first Linux IT job. There are three common approaches to this.

  1. Volunteer for a local non-profit. Whether this is something as remedial as teaching people how to use computers at first, it may soon turn into your managing their data stores and other server needs. Many of these opportunities evolve into the volunteer handling a variety of duties. Linux IT is no different.
  2. Apply for an IT help desk position. Sometimes this means working for a local ISP or perhaps a web hosting company. Even if neither of these seem to compliment your Linux career goals on the surface, it shows future employers that you’re able to handle difficult challenges when needed. Plus, it’s not uncommon for people to be recruited for better paying Linux IT jobs from these entry level positions. I’ve personally seen it happen many times. As long as your skills are up to par, you’re in a far better position when an IT position in the same company opens up than the new kid fresh out of school is.
  3. Network at industry events. I’ve had younger people tell me this approach to job hunting is dated and my reply is that the hiring managers at these events would disagree. Hone your skills, make up business cards listing your skills and contact information. Then begin introducing yourself to any booth or person at Linux industry events who you happen upon. I had a ten plus year consulting job that I got taking this approach. It works.

Building your Linux career: IT job interviews

Depending on the Linux IT job type you’re seeking, odds are you’re going to be interviewed by both HR managers and IT division managers. The former is more easily fooled by an exaggerated resume than the latter.

Choosing your first Linux IT job

It’s at this point you have to decide what next steps will make the most sense for you. As a general rule, this usually is broken up into the following segments.

Location of the job. Is there a commute? Since it’s highly unlikely anyone is going to hire a junior admin to work remotely, figuring out whether to commute or relocating is the best option.

Career path direction. Is the company you’re interested in working for going to make continued learning available to you? Do they pay for certs, conferences, and training? Not all of them do and if one of them does, this needs to be something to consider as it’s a tangible asset that will advance your career. As a junior administrator, I’d go so far as to suggest that a company that pays a smaller salary but pays for continued education is the better choice when starting out.

Company culture. When you’re given a tour of the place, do you get the sense that everyone is reasonably content with being there? As cliché as this must sound, I can’t impress upon your enough how important this is. As a junior administrator, you’re going to be seeking out help and mentorship from some of these individuals. If they hate being there, odds are so will you.

Can you do the job asked of you?  Remember what I said about being honest about your skills? Once hired, you’re expected to accomplish tasks that match the skills you’ve claimed to possess. Honing your skills and being in a workplace that encourages continued learning is going to present you with a very attractive Linux IT career.

Ever-evolving Linux IT

Remember what I said about your career evolving over time? That you may start out doing one thing only to shift gears and go another way? This is true when you’re starting out as a junior administrator. You may start off simply managing data stores only to move into DevOps one day. You may even feel like the skills you learn today won’t apply to your career later on if you decide to get into something a bit different.

Don’t worry, your skills are legacy assets that will only serve you as you progress through the IT ranks. By building up your basic Linux skills first, starting off in the trenches at a low level IT job, you’re learning secondary skills that will transform you into a more effective Linux IT employee.

Facebook, Google, Amazon, NASA, Tesla, even Microsoft. Linux is the operating system acting as the backbone for the world’s most powerful and innovative companies. Looking for a future proof technical skill? It’s hard to go wrong with Linux.

Enroll with us for Linux courses to gain the foundational Linux skills you need to pursue more advanced education and certification. Choose between two options, depending on your experience level. Unsure about which course is right for you? Its time you stopped and trained with us…

Artificial Intelligence – The new future…

Artificial Intelligence

One of the “most sought after” domain these days is Artificial Intelligence (AI). Artificial Intelligence (AI) capabilities for e-commerce and other Platforms today are able to leverage available information regarding similarities and dissimilarities between customers, along with the Phone. The ability to utilize the vast datasets regarding customer behavior and usage patterns acquired by e-commerce platforms, artificial intelligence – with its self-learning algorithms and intelligence, creates personalized shopping experiences for online buyers.

Here’s a snapshot of how Artificial Intelligence (AI) is slowly changing the world of business and shopping for good:

The Chatbots Revolution for both, machines and smart devices

AI is rapidly reducing manual effort in communication for the e-commerce platforms via natural language processing (NLP) and machine learning capabilities, AI’s chatbots are able to automate conversation with the buyers.

This can carry out the daily transactional conversation, which otherwise required human support staff. Furthermore, the chatbot-led conversations transpire with zero scope for human error. Chat assistants are further being used for CRM, personalizing buyer experience by addressing their queries.

This is the reason why e-commerce sites are today able to drive conversations with their users via AI. The Industry Gurus believe that e-commerce players to go big on the entire chatbots revolution. Gartner predicted that chatbots are going to replace 85 per cent of customer interactions by 2020.

Virtual Buying Assistants:

These days AI-powered virtual assistants, e-commerce sites are able to provide their shoppers with a personal fashion assistant. The technology assists shoppers through personalized recommendations, on the basis of their preferences and past usage patterns. For example, sending notifications or prompts when prices drop; the virtual assistants will let the shoppers know the instant there is a price change, this will help them to increase the footfalls on the site, leading to more successful conversions.

Analyzing Data:

Monotonous or Traditional merchandising systems no longer possess the required wherewithal to analyze large volumes of data, or read and predict consumer trends. This is where AI comes in, helping consumers with what to buy, based on their behavior patterns and preferences. The same also provides e-commerce sites with actionable insights to make their platform best suited for their buyers, and come up with the most relevant offers, campaigns, strategic messaging etc.

Making conversations and Improving Order Fulfillment:

Because of  the sheer number of mushrooming e-commerce platforms, consumers today are bombarded with a volley of messages. It not a surprise anymore, when most of the times important communication from e-commerce sites is missed by the customers.

To tackle these challenges, Companies using Artificial Intelligence exploit, Predictive Intelligence and Contextual Messaging functionalities to determine the right time to target a customer. This ensures higher conversation rates, whilst also improving brand’s engagement with its customers.

Furthermore, the noteworthy aspect of the technology is that the practice can be used to target each and every customer individually. Companies can now re-engage with every customer via strategic messaging, most opportune time, and a communication channel of their preference which makes it convenient for them.

AI potential has been utilized by e-commerce companies across the globe to minimize shopping cart abandonment, automate processes and optimize the conversion rate. E-commerce sites are increasingly adopting AI to provide a much more personal, intuitive and simplified experience to their patrons.

The future belongs to industry-level collaborations between AI and e-commerce giants, with the sole intention of putting forth the best platform for the customers.

What is Hadoop?


What is Hadoop?

It is a word which is used very often nowadays in the IT as well as some other industry sectors. It is often used in connection with Big Data. But very few know how it is related to Big Data.

Big data is the voluminous heterogeneous data in terabytes and Hadoop is a framework (not a single technology or a product) to process efficiently Big Data. Hadoop is a part of an Ecosystem to handle big data which comprises of various other supporting technologies and products.

Hadoop is an Apache open source framework written in java which has the potential to manage thousands of terabytes of data. It has quickly developed as basis for big data processing tasks like statistical analytics, business planning and processing huge volumes of data from sensors including IoT sensors. Hadoop is designed to scale up from single server to thousands of machines, each offering local computation and storage.

Hadoop Architecture



The main four modules of Hadoop Framework

  • Hadoop Distributed File System (HDFS) – A distributed file system which is capable of storing data across thousands of servers and provides access to application data.
  • Hadoop Yet Another Resource Negotiator (YARN) – A framework for resource management and schedule jobs across the clusters holding data.
  • Hadoop Map Reduce- It is a parallel processing system which is YARN based and maps the data and reduces to a result.
  • Hadoop Common- They are the Java libraries and utilities supporting other modules.

The other softwares which are part of the Hadoop Ecosystem

  • Apache Flume– It is meant for Data Movement. It streams logs into Hadoop. It is a reliable & distributed service to efficiently collect, aggregate and move large amounts of streaming data into HDFS
  • Apache Hive-It is a Data Warehouse Infrastructure on top of Hadoop for providing summaries, query and analysis. It allows SQL programmer to SQL type of statements in HQL
  • Apache Pig-It is a high level platform for creating program on Hadoop to analyze large data sets.
  • Apache Hbase– It is an open source, non-relational, column oriented database management system which runs on top of HDFS. It is written in Java and modeled after Google’s Big Table.
  • Apache Spark-It is a powerful open source which uses its standalone cluster mode and can run not only on Hadoop Yarn but also on Apache Mesos and Cloud.
  • Apache Zookeeper, Apache Oozie, Apache Sqoop, Cloudera Impala and few others.

Advantages of Hadoop

  • It is scalable
  • Cost-effective
  • Flexible
  • Fast
  • Hadoop framework allows the user to quickly write and test distributed systems and utilizes the underlying parallelism of the CPU cores.
  • Hadoop does not rely on hardware to provide fault-tolerance and high availability (FTHA), rather Hadoop library itself has been designed to detect and handle failures at the application layer.



Understanding Business Intelligence

Business Intelligence is the broad set of tools, applications and techniques that provide organizations the visibility into complete business operations. It gathers data from internal as well as external sources, performs the analysis by running queries and then present the reports, spread sheets, visualisations, dashboards for the for the decision makers as well as functional people.

The main purpose of the business intelligence is to provide support for the Data-Driven Business Decision Making. It is also referred to as Decision Support Systems (DSS). It includes technologies and applications like Data Warehouses, Executing Information Systems and Online Analytical Processing (OLAP).

Bringing together all the data from the heterogeneous sources and integrating and creating a Data Warehouse it is called Data-warehousing. It is the core of an organization’s business intelligence system and is facilitated by the ETL tools.

The functions of data Warehousing tools and utilities are

  • Data Extraction
  • Data Cleaning
  • Data Transformation
  • Data Refreshing

Data visualization is presenting or reporting the information in a visually appealing method which helps understand the necessary details from the data in a better, faster and absorbing way. It involves selecting the most relevant and most appropriate infographics/chart/graph/reporting style for the management and executive dashboards keeping in mind the nature of the data, report to be made and the audience. More the dashboards are appealing and communicative, better the information sharing.

Business Intelligence is an approach which is similar to a rear-view. It answers the questions like

  • What Happened?
  • When did it happen?
  • Who made it happen?
  • How and When did it happen?

Based on these questions, the organisation work to derive answers and further do the analytical study part.

Benefits of Business Intelligence:

  • Management Processes are enhanced.
  • Business operations processes are also enhanced.
  • Planning, controlling, measuring and/or applying changes that results in increased revenues and reduced costs.
  • Intelligent prediction of future.
  • It empowers the organization with
    • Quick and efficient process requests
    • Quick response to any change in organization
    • Efficient Information sharing
    • Improvise reporting system
    • Delivery of relevant information to both local and remote personnel

Data Warehousing and BI is one of the very important modules in the entire course of Data Science. There is lot of demand for the people in this field as the amount of data has been increased hugely. More and more Big Data technologies are being adopted by the various companies and hence knowledge of BI tools and concept of data warehousing are imperative to work with Big Data.

Bicard offers in-depth Data warehousing and BI course for the experienced professionals as well as fresh graduates. It is Also an integral part of 6 months PG Diploma programme in Big Data Analytics & Machine Learning.
