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

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…

Mike Romeri, A2Go CEO

April 21, 2020

As commerce slowly opens up in our world over the next few months, competition for customers will accelerate like never before. It remains to be seen how big the pent-up demand will be for dining out, consuming goods and services, and travel, for starters.

Digital Transformations in the Post-Covid World

The term "digital transformation" has been around now for a couple of years. Like so many such terms, it was something of a neologism, a phrase much like Big Data or, for that matter, Data Scientist, that started out more as market-speak than anything else, but that, for one reason or another, started accreting a second…

The Art of Thinking Like a Data Scientist: The Movie

The Covid19 pandemic has given me a chance to catch up on some reading. One of the books I recently finished reading is called “Building a Story Brand” by Donald Miller. It’s a short and very effective read (which all books should be). The premise of the book is that all sales and marketing messages should be structured like a movie, and successful movies have a standard approach for telling an engaging story (see Figure 1).…
