Themes and Conferences per Pacoid, Episode 6
In Paco Nathan's latest column, he explores the role of curiosity in data science work as well as
Rev 2, an upcoming summit for data science leaders. This episode unpacks curiosity as a core attribute of effective data science, looks at how that informs process for data science (in contrast to Agile, etc.), and digs into details about where science meets rhetoric in data science. Overall, these topics are among the themes you can expect at the next
Rev!

Pricing algorithms can learn to collude with each other to raise prices
Pricing algorithms have become ubiquitous in online retail as automated systems have grown increasingly affordable and easy to implement. But while companies like airlines and hotels have long used machines to set their prices, pricing systems have evolved. They have moved from rule-based programs to reinforcement-learning ones, where the logic of deciding a product’s price is no longer within a human’s control...

Cyclical Stochastic Gradient MCMC for Bayesian Deep Learning
The posteriors over neural network weights are high dimensional and multimodal. Each mode typically characterizes a meaningfully different representation of the data. We develop Cyclical Stochastic Gradient MCMC (SG-MCMC) to automatically explore such distributions. In particular, we propose a cyclical stepsize schedule, where larger steps discover new modes, and smaller steps characterize each mode. We prove that our proposed learning rate schedule provides faster convergence to samples from a stationary distribution than SG-MCMC with standard decaying schedules...

What Trump's Executive Order on AI is missing
President Trump signed an executive order on February 11 meant to shore up our competitive position in the international race for AI supremacy, but it is short on concrete steps. As the CEO of an artificial intelligence research institute, I am calling on him to include a special visa program for AI students and experts to help us win this race for the sake of both economic vitality and national security...
