Connections between Neural Networks and Pure Mathematics

Nowadays, artificial intelligence is present in almost every part of our lives. Smartphones, social media feeds, recommendation engines, online ad networks, and navigation tools are examples of AI-based applications that affect us on a daily basis.

Deep learning has been systematically improving the state of the art in areas such as speech recognition, autonomous driving, machine translation,…

Neural Quantum States



Picture by By Tatiana Shepeleva/shutterstock.com

One of the most challenging problems in modern theoretical physics is the so-called many-body problem. Typical many-body systems are composed of a large number of strongly interacting particles. Few such systems are amenable to exact…

Data Science insights after a rookie year in the industry

Countless hours of online courses haven’t prepared me for challenges in my first full-time position as a data scientist. Yes, I learned Python well enough to land the job, but the reality of developing a data science project went beyond my anticipations. Now it’s time for me to pinpoint several misconceptions and matters that are not voiced enough.

Do not take data for granted…

Traveling to Other Planets with Google Maps

Interesting application leveraging very big data, as you can zoom in to check out pretty detailed landscape on a few nearby planets and satellites. It would be even better if it allowed you to simulate space travel. At a speed 32 million times faster than the speed of light, it would take you 4 seconds to reach the closest star (Alpha Centauri): that's how fast you need to travel to see the stars really moving in the sky. By contrast, space travel at just the speed of light would make stars…

Setting the Cutoff Criterion for Probabilistic Models

For decision making, human perception tends to arrange probabilities into above 50% and below - which is plausible. For most probabilistic models in contrast, this is not the case at all. Frequently, resulting probabilities are neither normal distributed between zero and one with a mean of 0.5 nor correct in terms of absolute values. This is not seldom an issue accompanied with the existence of a minority class - in the underlying dataset.

For example, if the result of a…

Data Science Job Titles to Look Out for in 2020

Data scientists are disappearing. No, not in the physical sense (no rapture here), but in the job market. The term “data science” has been a catch-all term for years, but as companies better learn what goes into hiring data science teams, the generic “data science” job titles might go the way of the dodo.

Not that we’re sad about it. Confusing job postings and a misunderstanding of the fundamentals of working in data science has led to disillusionment on both sides.…

Naive Bayes Classifier using Kernel Density Estimation (with example)

Bayesian inference is the re-allocation of credibilities over possibilities [Krutschke 2015]. This means that a bayesian statistician has an “a priori” opinion regarding the probabilities of an event:

p(d)   (1)

By observing new data x, the statistician will adjust his opinions to get the "a posteriori" probabilities.

p(d|x)   (2)

The conditional probability of an event d given x is the share of  the joint…

A beginner’s guide to BigQuery Sandbox and exploring public datasets.

As you might realize by now, writing SQL queries is one of the essential skills any inspiring data analyst needs to master. After all, larger datasets are typically stored in relational databases and Structured Query Language is the language that helps us communicate with such databases. Sure, NoSQL is gaining…

Schmarzo’s Favorite 10 Infographic Blogs for 2019

2019 was a year full of outstanding customer engagements and provocative teaching experiences across numerous universities.  My eyes were opened to many new opportunities to integrate economics, design thinking, big data and data science (AI / ML / DL) to further my case for a Nobel Prize in Economics (which I’d prefer not to be awarded posthumously).  That includes helping organizations:

  • Monetize a digital asset (data) that never wears out, never…

Web UI Development: Why Vue.js is the Idea Choice

As anyone involved in the developing world would tell you, the app’s UI is one of its most critical elements, if not the most important. After all, the design is one of the first things that any user sees and if that isn’t appealing, easy, and convenient, there should be no wonder about the app’s inability to garner better customers. Thankfully, most folks seem to understand this now and yet find themselves struggling with a critical question in their pursuit of good design: Which framework…

AI Ethics Challenge: Understanding Passive versus Proactive Ethics

Several of my friends have challenged me to get involved in the AI ethics discussion. I certainly do not have any special ethics training. But then again, maybe I do. I’ve been going to church most Sundays (and not just on Christmas Eve) since I was a kid and have been taught a multitude of “ethics” lessons from the Bible. So, respectively, let me take my best shot at sharing my thoughts about the critical importance of the AI Ethics topic.

What is AI…

Can Reinforcement Learning Break Through in 2020

Summary:  Reinforcement Learning (RL) is going to be critical to achieving our AI/ML technology goals but it has several barriers to overcome.  While reliability and a reduction in training data may be achievable within a year, the nature of RL as a ‘black box’ solution will bring scrutiny for its lack of transparency.

It's time for Time-series Databases

The history of Database management systems could be interpreted as a Darwinian evolution process.

The dominance of relational databases gives way to the data warehouses one, which better adapt to the earliest business intelligence requirements; then, alongside the rise of the most popular big data platforms such as Hadoop or spark, comes the era of the NoSQL…
