Gradient Descent

Gradient descent is by far the most popular optimization strategy, used in machine learning and deep learning at the moment. It is used while training your model, can be combined with every algorithm and is easy to understand and implement. Therefore, everyone who works with Machine Learning should understand it’s concept. After reading this posts you will understand how Gradient Descent works, what types of it are used today and what are their advantages and tradeoffs.

From 0 to $100K+ data science job in 6 months

I have loved being a data scientist. The job is challenging. The job market is great. I can't imagine any other job that would provide more career fulfilment for me now. This is my ideal career. Across the way, I see people that I care about trying to break into this field. Wondering what to study, what skills they need, feeling clueless about how to get that first real data science job in this market. This article is for them.

Data Science Compensation Survey

A report analysis that caught my eye was a comparison of Data Scientist salaries on the intersection of experience and education, with experience levels of 1-3 years, 4-8 years, and 9+ years, and educational attainment of Masters vs PhD. Not surprisingly, there’s an over 25% difference in median salary by category of advancing experience, along with a consistent differential between Masters and PhD of roughly 10%. Makes sense to me: obviously, experience is critical and PhD’s may well bring more of the Science/Research Methodology component of DS to the table from the get-go than do most Masters-trained practitioners.

Deploying new technologies will create the need for new talent. So, if you think tech, think talent too!

Behind every technological innovation that hits the market, there is a team of highly skilled professionals working jointly to make the innovation a success. And it is obvious that when technologies come in, employees are expected to update their knowledge and skills to be able to leverage the technology. From bridging the talent gap to incubating the right culture to modifying the infrastructure, every small thing should be taken into account when companies plan to harness the power of any new technology.

How To Stay Relevant in the Age of A.I.

Knowledge isn’t power. Almost everything we know is either currently on the internet, or will be soon. If we reach a stage when every person and machine has access to the same information, what will set you apart from the pack? Your power is through connection. One way you’ll stand out is by cultivating an ability to communicate knowledge in a more compelling way than other people or machines can do it. We yearn for human connection, yet few people develop their skills in this area.

What is computer vision?

Computer vision is the field of computer science that focuses on replicating parts of the complexity of the human vision system and enabling computers to identify and process objects in images and videos in the same way that humans do. Until recently, computer vision only worked in limited capacity. Thanks to advances in artificial intelligence and innovations in deep learning and neural networks, the field has been able to take great leaps in recent years and has been able to surpass humans in some tasks related to detecting and labeling objects.

Supercomputing, The heart of Deep Learning and Artificial Intelligence

How supercomputing could contribute to improving Machine Learning methods?The tasks of training Deep Learning networks requires a large amount of computation and, often, they also need the same type of matrix operations as the numerical calculation intensive applications, which makes them similar to traditional supercomputing applications. Deep Learning applications work very well in computer systems that use accelerators such as GPU or field-programmable gate arrays (FPGA), which have been used in the Supercomputing field for more than a decade within the walls of the supercomputing research centers.

Why your Tech interview process may be flawed

Sometimes an interview goes wrong, and it’s not always the fault of the candidate. This person may be considered the creative/visual type, with strong expertise in building solid UI elements that can be used in web applications, but then gets asked in the interview how to solve a complex algorithm around binary trees or big O on a whiteboard. But most of the time a job doesn’t require such complexity on a daily basis. In all seriousness, having a poor interviewing process reflects very badly on the company.

Factoring data protection into a digital transformation strategy

Digital transformation and data protection; to some that may feel like a contradiction in terms, but in fact, the two can be interdependent.  With digital transformation, there is a temptation. It’s the allure of just focusing on the deluge of information available and the potential for business advancement, if only one can successfully aggregate, interrogate and monetise it. Digital transformation and data protection, on the other hand, seem to be at odds. After-all, the principles of adding more control to data usage can feel like roadblocks on the path to becoming data driven.

Do you need a graduate degree for data science?

Do you need a graduate degree for data science? Maybe so. Maybe not. In a rapidly developing field like data science, convention can often lag considerably behind what’s optimal. As a society, our perception of the value of graduate education is one of the aspects of conventional wisdom that’s most badly in need of catching up to reality. None of this means that formal education, or even graduate degrees aren’t worth obtaining, of course. But no one should take the need for a Master’s or a PhD for granted: you might want to rethink your strategy.

These are 5 Kinds of problems where Deep Learning is applicable, namely Generative Computational Modeling, Complex Predictive Systems, Adaptive Imitation Generative Design Exploration, and Decision Support Systems. These five areas are all advanced new capabilities that could not have happened without the arrival of Deep Learning. It would be unrealistic for a company to specialize in all five areas. Any company focusing on a DL product must specialize in any one of these five areas. Furthermore, each of these five areas supports different verticals.

Comparing Different Classification Machine Learning Models for an imbalanced dataset

A data set is called imbalanced if it contains many more samples from one class than from the rest of the classes. Data sets are unbalanced when at least one class is represented by only a small number of training examples (called the minority class) while other classes make up the majority. There are many reasons why a dataset might be imbalanced: the category one is targeting might be very rare in the population, or the data might simply be difficult to collect.

Applications of Reinforcement Learning in Real World

While Convolution Neural Network (CNN) and Recurrent Neural Network (RNN) are becoming more important for businesses due to their applications in Computer Vision (CV) and Natural Language Processing (NLP), Reinforcement Learning (RL) as a framework for computational neuroscience to model decision making process seems to be undervalued. Besides, there seems to be very little resources detailing how RL is applied in different industries. Despite the criticisms about RL’s weaknesses, RL should never be neglected in the space of corporate research given its huge potentials in assisting decision making.
