Now, are you trying to understand some of the skills necessary to get a Machine Learning job? A great candidate should have a deep understanding of a broad set of algorithms and applied math, problem solving and analytical skills, probability and statistics and programming languages.

Here is a list of key skill sets in detail:

  1. Programming Languages like Python/C++/R/Java: If you want a job in Machine Learning, you will probably have to learn all these languages at some point. C++ can help in speeding code up. R works great in statistics and plots, and Hadoop is Java-based, so you probably need to implement mappers and reducers in Java.
  2. Probability and Statistics: Theories help in learning about algorithms. Great samples are Naive Bayes, Gaussian Mixture Models, and Hidden Markov Models. You need to have a firm understanding of Probability and Stats to understand these models. Use statistics as a model evaluation metric: confusion matrices, receiver-operator curves, p-values, etc.
  3. Data Modeling & Evaluation: A key part of this estimation process is continually evaluating how good a given model is. Depending on the task at hand, you will need to choose an appropriate accuracy/error measure (e.g. log-loss for classification, sum-of-squared-errors for regression, etc.) and an evaluation strategy (training-testing split, sequential vs. randomized cross-validation, etc.)
  4. Machine Learning Algorithms: Having a firm understanding of algorithm theory and knowing how the algorithm works, you can also discriminate models such as SVMs. You will need to understand subjects such as gradient decent, convex optimization, quadratic programming, partial differential equations and alike.
  5. Distributed Computing: Most of the time, machine learning jobs entail working with large data sets these days. You cannot process this data using single machine, you need to distribute it across an entire cluster. Projects such as Apache Hadoop and cloud services like Amazon’s EC2 makes it easier and cost-effective.
  6. Advanced Signal Processing techniques: Feature extraction is one of the most important parts of machine-learning. Different types of problems need various solutions, you may be able to utilize really cool advance signal processing algorithms such as: wavelets, shearlets, curvelets, contourlets, bandlets.
  7. Other skills:
    1. Update yourself: You must stay up to date with any up and coming changes. It also means being aware of the news regarding the development to the tools (changelog, conferences, etc.), theory and algorithms (research papers, blogs, conference videos, etc.).
    2. Read a lot: Read papers like Google Map-Reduce, Google File System, Google Big Table, The Unreasonable Effectiveness of Data.

The next question you would have is, “What can I do to develop these skills?” Unless you already have a strong quantitative background, the road to becoming a Machine Learning Specialist will be a bit challenging – but not impossible.
However, if it’s something you’re sincerely interested in, and have a passion for Machine Learning and lifelong learning, don’t let your background discourage you from pursuing Machine Learning as a career.

Infographic – Should You Fear 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. The goal of machine learning is to get computers to learn in a similar manner to humans.

Machine learning is a type of artificial intelligence that helps computers learn without having to be programmed by a person. These computers are programmed in a way that focuses on data that they receive on a regular basis. This data can then help the machine “learn” what preferences are and adjust itself accordingly.

Nowadays, the development in Artificial Intelligence (AI) have brought us to the stage where organizations are using a various algorithms, analysis, and experience to learn and program themselves without human intervention.

This type of procedure will create changes too many industries. The use of machine learning has grown exponentially in the past few years, and you may not realize how widely it is used.

Following stats are just tip of the iceberg:

  • 85% of customer interactions will be managed without humans by 2020.
  • 38% of jobs could be replaced by AI/machine learning by the 2030s.
  • 20% of top executives rely on machine learning to run their businesses.

What You Would Need To Become a Machine Learning Engineer?

Have you ever wondered why your Facebook feed contains several sponsored advertisements for digital cameras the day after you do a Google search for good digital cameras? Or have you seen supercomputers like Watson max all questions on a show and go on to beat established quiz enthusiasts hands down? All of it is machine learning in action for you, where those computers or software systems have been fed large amounts of data and also given algorithms that help them think like a human brain would, to make educated decisions. Artificial intelligence and machine learning have captured the imagination of scientists, corporates, users and even job seekers all over the world. As a job seeker, though, you should be clear about the skills you will need before you jump on to the bandwagon.

Fundamental Requirements

Many job seekers have a wrong notion that picking up a few programming languages is the first step to a machine learning career. But the skillsets required going some way further back. Since machine learning will involve a non-human entity making correct predictions and inferences, therefore the focus is on cold, hard logic and mathematical principles. You need to have a strong grounding in probability (Markov and Bayes should be names familiar to you!) and also statistics. You need to have the knack for looking at a big pile of data (probably unstructured), and be able to identify gaps in it, and also spot trends and patterns.

Programming Requirements (Skills)

This is the core of the skillsets you would require and would be likely to require you to have a formal certification too. You need to be able to use your programming skills and your knowledge of data structures and computer architecture to create dynamic algorithms. You should be adept at parallel programming, and the basics of stacks and b-trees should come easily to you. A good machine learning engineer needs to be proficient in application programming interfaces (APIs), and also have the ability to use machine learning libraries created by other developers.

Programming Requirements (Languages)

As we know it today, machine learning is technically bound to any one particular programming language, so you do have a choice there. But let us examine the three most popular programming languages that machine learning engineers commonly use. First up is Python whose multiple libraries like NumPy and SciPy (and also specific machine learning libraries like Theano or TensorFlow) make it one of the most popular programming languages for machine learning. Then there is another language called R, which lends itself very well to machine learning. This programming language is a favourite of data scientists and statistical programmers and has been happily adopted by several machine learning engineers. And finally, we have the old warhorse C++, which is not as advanced as Python or R, but because it is good for networking protocols and infrastructure interfacing, it is still used for machine learning programming.

Apart from these technical skills which you need, two more skills are also necessary – the ability to look at a system holistically (including sales, inventory, billing etc.), and the ability to remember that your output would have machines as the audience, not humans! So are you up for it?

Let us understand this with the help of an example, assume that you are working for a retail store. And let us say the company wants to design a reward system, through which coupons are issued based on facts like, purchase history, with the intent that the issued coupons will actually be used. Now traditional data analysis approach would be to study the historical data, and figure out trends, and subsequently propose a strategy. But in the Machine Learning approach an engineer would need to create an automated coupon generation system, however, you will only be successful, if you understand the peripheral functions of the environment like the inventory, Catalogue, Pricing, Purchase Orders, Invoice Generation, CRM Software etc.,

So the skill requirement is not only restricted to the application of machine learning algorithms and the understanding of what to apply when, it is also equally important to understand the Interconnected Relationships of these Functions so that you can then successfully create a software which integrates interface, for an effective output.

Now for the real deal, the actual technical skills you need to kick-start your career as a machine learning engineer. You need to have a good and detailed understanding of the ML Algorithms, Mathematics, Skills in Problem Solving and Analytical thinking, and above all an innate sense of Curiosity. In addition to this, the below mentioned Skill….

Programming Languages like C++ can help in speeding code up, R, Python & Java works wonders for statistics.

Theories like Naïve Bayes, Hidden Markov Model, would require you to have a good understanding of Probability and Statistics so that you can comprehend these models.

A firm understanding of Applied Math and Algorithm theory, along with the knowledge of how the algorithms works, will help you discriminate models.

You will also need to skill yourself on Distributed Computing, as a machine learning role would require you to work on large datasets, which cannot be processed using a single machine, but you will be required to distribute it across an entire cluster

Data Modelling and Evaluation, Data Modelling is the process of estimating the underlying structure of any given dataset, with the intent of finding a pattern that is useful or picks up predictions of previously unseen trends. This process will be futile if the appropriate evaluation is not done to access the effectiveness of the model. So that you can choose an appropriate error measure, and apply an evaluation strategy, it is important that you understand these measures, even while applying standard algorithms.

Software Engineering and System Design, are considered as the typical output of any ML engineer’s deliverables. It is that small component that becomes a part of the larger ecosystem. Like said earlier you need to make the puzzle, keeping in mind the various components, ensure they work with the help of proper communication of the system with the interface, and finally carefully design the system such, that any bottlenecks are avoided and the algorithms successfully scale along with the volume of data.

It is hence without a doubt that the demand for machine Learning Engineers will rise exponentially, as the challenges of the world are complex and only complex systems will be able to solve them. Machine Learning Engineers are building these complex systems, therefore you become the future!

Everything You Need To Know About Machine Learning and Deep Learning

Artificial Intelligence (AI), Machine learning (ML) and Deep Learning (DL), can be imagined as the three bears from Goldilocks staying together in a house, where each member has a specific use but yet conceptually they are interconnected. Artificial Intelligence is the big umbrella under which resides the Machine Learning concepts, and Deep Learning can be referred to as a sub-set of Machine Learning. So while Deep Learning and subsequently Machine learning comprises of Artificial Intelligence, the other way around is not necessarily true.

The field of data science is buzzing with these terminologies, and in all the noise it is very easily misinterpreted, and often Machine Learning and Deep Learning are used interchangeably for one another. One thing is certain that Deep Learning is a technique for implementing Machine Learning.

Let us understand this by breaking down the puzzle….

Artificial Intelligence orchestrates the capacity of a machine to comprehend complex human tasks like, decision making, understanding spoken language, detecting fraud, in short, it enables a machine to imitate intelligent human behaviour.

Machine Learning is surely a part of AI, where it enables a computer to act in a specific way without the need for explicit programming. This is imperative as the volume of data is ever increasing and to keep up, the machine should have the capability of implementing effective algorithms which can effectively and efficiently make predictions by recognising patterns. To perform the same, data scientists have a number of existing ML methods or Algorithms which can be easily applied to any data problem, at the same time it can be applied to a number of real-life use cases, for example, recommendation engines, or applying Natural Language Processing (NLP) in chat logs.

Deep Learning is a subset of ML and when data scientist refers to the term deep learning they most often mean Deep Artificial Neural Networks or alternatively Deep Reinforcement Learning.

Deep Artificial Neural Networks are essentially a set of Algorithms which are popular in recent times, for setting new records in accuracy while dealing with complex problems like, Image Recognition, Sound Recognition, Recommendations Systems, etc…, To add on, one can easily define DL in a similar manner to ML, so it can be safely said that DL also enables a computer to act in a specific manner without the need of explicit programming, with the addition that DL ensures it produces results with higher accuracy.

DL is often more complex as compared to ML, the prerequisites to DL would be a high-performance computer and huge volumes of Labelled data to give reliable results.

ML can be used with a small volume data set and has a shorter training time, while DL will be effective with large volume data set and often requires a longer training time. In ML you can use your own features, so for example, if you need a computer to be trained on recognising an image of a cat, you will first need to key in all the relevant features of a cat into it. In DL you will need to feed the computer with large volumes of data with cat images, and the system will choose the features on itself which characterises a cat. Hence the training time is longer, while the chances of accurate information are higher due to the complexity of reaching the conclusion, in some cases, it is more accurate than humans.

Driverless Cars, Movie Recommendations and preventive health care are all possibilities enabled by Deep Learning. DL in the future could be responsible for machine assistance in possibly all aspects of life. Deep Learning has the promise of taking the application of AI from fantasy to reality.
