Python Is Gaining Popularity against SAS, R – Says Burtch Works

Python is on the rise – though R and SAS are languages of choice amongst the data scientists but R is soon ascending the steps of analytics ladder. Already a lot of practitioners and data scientists have armed themselves up with this incredible R Programming tool for future career aspirations. To add volume to the statement, we’ve a new survey from a high-end recruitment agency, Burtch Works – let’s see what their comprehensive report says about our preferred language.

The survey began with R, an open source tool and SAS, another commercial tool. Later in 2016, Burtch Works added another open source tool, Python.

This year, however we witnessed something that never happened before. There’s no clear winner, this time – Python stood at 33%, R at 33% and SAS at 34%. “This is the first year that we’ve seen SAS, R, and Python all at the same level of preference,” said Linda Burtch, a quantitative recruiting specialist and Managing Director at Burtch Works.

According to the results, R declined slightly as compared to last year figure, whereas SAS remained fairly flat. On a positive note, Python continued reflecting an increasing trend over the last two years, since its inclusion.

“The most noticeable trend from the 2018 data was Python’s ascension, and how Python’s growing popularity has been eroding support for R,” Burtch shared with InformationWeek. “Data scientists have typically strongly preferred Python, but predictive analytics professionals working primarily with structured data are shifting that way as well.”

But what makes Python so fetching? It is considered to be a very strong language for machine learning, perfect for data visualizations and other statistical applications, better than SAS and R. Budding professionals enjoy working with Python(48%) as compared to R(38%) and SAS(14%). Survey reveals that open source tools, such as R and Python are in-favor of professionals who are young and new in technology.

Going by the survey results, the use of R has fallen drastically from 50% in 2016 to below 40% this year. At the same time, the growth of python has been phenomenal – in 2016, it was standing at 20% and this year, it is hovering around 50%.

“Python gained support in almost every category we examined this year and has especially taken hold at the early career level, with professionals who have five or less years of work experience,” Burtch concluded to InformationWeek.

As parting thoughts, Python is considered to be a very versatile programming language. Its popularity soared in recent years – its usage and employability knows no bounds. For beginners and newcomers, it’s like a treasure trove waiting to be discovered. So, if you are one of them, it’s high time to consider a Machine Learning Using Python certification program – easy to learn and highly accessible, Python programming is ideal to get started. Most importantly, its simplified syntax with an undue focus on natural language is an added bonus.

The Math Behind Machine Learning: How it Works

$The Math Behind Machine Learning: How it Works$

It is evident that in the last few months, we have had several people showcase their enthusiasm about venturing into the world of data science using Machine Learning techniques. They are keen on probing the statistical regularities and building impeccable data-driven products. but we have made an observation that some may actually lack the necessary mathematical knowledge and intuition to get the framework for achieving results with data. And this is why we have decided to discuss this lacking through our blog.

In the recent times, there has been a noticeable upsurge in the availability of several easy-to-use machine and deep learning packages such as Weka, Tensorflow, scikit learn etc. But you must understand that machine learning as a field is one that has both statistical concepts, probabilistic concepts, computer science and algorithmic concepts to arise from learning intuitively from available data and also is about determining the patterns and hidden insights, which can be used to build intelligent applications. While still having the immense possibilities of Machine Learning and Deep Learning which is a thorough mathematical understanding of many of these techniques which is necessary for a good grasp of the internal workings of algorithms to achieve a good result.

Enrol in the most comprehensive machine learning course in India with us.

Why we must think about the math?

To explain why it is necessary to behind the scenes into the mathematical details of Machine Learning, we have put own a few important points:

To choose the right algorithm which will include giving considerations, to accuracy, to the right training time, complexity of model, number of parameters and the number of features.
To choose parameter settings and to validate the strategies
To indentify the under-fitting and over-fitting by understanding the bias-variance trade off.
For acquiring ample confidence about the interval and uncertainty

The level of math one will need:

The primary question when one tries to understand an interdisciplinary field such as Machine Learning, is the amount of math needed and the level of math needed to understand these techniques.

The answer to this question is not as simple as it may seem and is multidimensional which, depends upon the level and interest of the individual. Research conducted in these mathematical formulations and theoretical advancements for Machine Learning is an ongoing process and a few researchers are already working on few more advanced techniques. However, we will state the least amount of math that is a must have skill for being a successful Machine learning Engineer/ Scientist is the importance of each and every mathematical concept.

Linear algebra:

This is the math skill to have for the 21^st century. One must be well-versed with the topics of Principal Component Analysis (PCA), Singular Value Decomposition (SVD), Eigendecomposition of a matrix, LU Decomposition, QR Decomposition/Factorization, Symmetric Matrices, Orthogonalization & Orthonormalization, Matrix Operations, Projections, Eigenvalues & Eigenvectors, Vector Spaces as these norms are absolutely necessary for the understanding and the optimization methods for machine learning. The best thing about linear algebra is that there are a lot of online resources.

Probability theory and statistics:

Machine learning and statistics are not too different a field. And in reality some people have actually defined Machine Learning as “doing statistics on a Mac”. A few fundamentals that are a must have for machine learning are – Combinatorics, Probability Rules & Axioms, Bayes’ Theorem, Random Variables, Variance and Expectation, Conditional and Joint Distributions, Standard Distributions (Bernoulli, Binomial, Multinomial, Uniform and Gaussian), Moment Generating Functions, Maximum Likelihood Estimation (MLE), Prior and Posterior, Maximum a Posteriori Estimation (MAP) and Sampling Methods.

Multivariate calculus:

Differential and Integral Calculus, Partial Derivatives, Vector-Values Functions, Directional Gradient, Hessian, Jacobian, Laplacian and Lagragian Distribution are some of the necessary topics necessary for understanding ML.

Algorithms and Complex Optimizations:

In order to realize the computational efficiency and scalability of our Machine Learning Algorithm and for exploiting the sparsity in the dataset, this concept is necessary. One must have knowledge of data structures such as Binary Trees, Hashing, Heap, Stack etc, and Dynamic Programming, Randomized & Sublinear Algorithm, Graphs, Gradient/Stochastic Descents and Primal-Dual methods.

A few other mathematical skills that are often necessary for understanding ML are the following Real and Complex Analysis (Sets and Sequences, Topology, Metric Spaces, Single-Valued and Continuous Functions, Limits), Information Theory (Entropy, Information Gain), Function Spaces and Manifolds.
