Building Up Stable Data Science Teams

Most of the big organizations are struggling with AI transformation. Data science projects are either taking too long to complete or would never get into production. 

Among various reasons, the most common is the lack of a stable data science team. Due to high demand, the turnover rate is very high in data science, unfortunately. Data science managers or leaders typically go around this problem by focusing on the following:

  • acquire best data science talent
  • retain…

Neuromancer Blues: Threading vs Multiprocessing

Neuromancer Blues" is a series of posts where I would like the reader to find guidance about overall data science topics such as data wrangling, database connectivity, applied mathematics and programming tips to boost code efficiency, readability and speed. My examples and coding snippets will be as short and sweet as possible in order to convey the key idea instead of providing a lengthy code with poor readability that damages the purpose of the…

Randomised algorithms

Randomised algorithms are built on statistical features played by random numbers.

Quicksort is a good example to illustrate this algorithm. For instance, in a class of taller students would naturally go at the back and…

Don't Buy Data – Invest In It

There are some expressions about data that are getting a bit tired: Data is the new oil; In God We Trust (all others must bring data); Buy data, sell high...

Okay, you caught me, I kind of made that last one up. But, the point stands: the narrative around data tells us we all understand that it has tremendous value.

The 4 Ms of Data

Data teams are tasked with gathering information from within their company and from any number of external sources, tying it all…

Up-skilling in the Lock-down

Friday the 13th of March: day one of the Dutch corona lock-down. I was almost out the door to deliver day 4 of a data science product owner training at the University of Amsterdam, but somehow hadn’t connected the dots that the university closings announced the previous evening meant my training was also cancelled. By force of habit,…

COVID-19 Lesson: Digital Transformation Is an Essential Service

The COVID-19 crisis has hammered home the importance for organizations to become more digital.  And I suspect that most organizations are thinking that just means being able to support remote customer engagements and business operations.  But that’s not nearly sufficient.  Organizations that are thriving during COVID-19 are those that have gone beyond just “digitalizing” their engagements and operations, but are actively leveraging granular customer,…

Accelerating aggregate MD5 hashing up to 800% with AVX512

By Frank Wessels



Introduction

While MD5 hashing is no longer a good choice when considering a hash function, it is still being used in a great variety of applications. As such any performance improvements that can be made to the MD5 hashing speed are worth considering.

Due to recent improvements in SIMD processing (AVX2 and especially AVX512) we are providing a Go …

Difference between Binomial, Poisson and Hypergeometric Distribution in One Picture

There are a few key differences between the Binomial, Poisson and Hypergeometric Distributions. These distributions are used in data science anywhere there are dichotomous variables (like yes/no, pass/fail). This one picture sums up the major differences.…

Which Face is Real? Applying StyleGAN to Create Fake People

A Generative model aims to learn and understand a dataset’s true distribution and create new data from it using unsupervised learning. These models (such as StyleGAN) have had mixed success as it is quite difficult to understand the complexities of certain probability distributions. 

In order to sidestep these roadblocks, The Adversarial Nets Framework was created whereby the generative model is pitted against an adversary: a discriminative model that…
