In this article, we provide a general overview of how our teams leverage forecasting to build better products and maintain the health of the Uber marketplace.
This is an amazing behind-the-scenes look at how Uber does forecasting. Includes detailed thoughts on model selection, training approach, uncertainty estimation, and more. Must-read.
Data science code doesn’t always produce the same results when you run it multiple times, which can make debugging a nightmare. This article goes into the three areas that cause reproducibility problems in code—non-deterministic code, changes in data, and changes in environment—and gives practical tips for improving reproducibility.
I love this post. Such an important topic, and I’ve never actually seen a good post that covers it before.
In this post, we’ll start with the intuition behind LSTM ’s and GRU’s. Then I’ll explain the internal mechanisms that allow LSTM’s and GRU’s to perform so well. If you want to understand what’s happening under the hood for these two networks, then this post is for you.
There’s a ton of effort put into the illustrations in this post and it adds a lot. New to GRUs? Gated Recurrent Unit networks are an innovation on top of RNNs.
tl;dr: We observed that Dynamic Programming is the common base of both database query optimization and reinforcement learning. Based on this, we designed a deep reinforcement learning algorithm for database query optimization we call DQ. We show that DQ is highly effective and more generally adaptable than any of the prior approaches in the database literature.
Database research meets AI. Academic; points towards the future .
Have you ever found yourself answering the question “But why is Redshift (or Snowflake or Bigquery, etc) faster than Postgres?” I answer this question a lot—multiple times a week. This is the single best answer to that question I’ve ever seen, and it goes deep into topics like column pruning and compression. Dense; very worthwhile.
…the right to an explanation as defined in GDPR may be harder than expected to implement. This does not invalidate the basic premise that individuals have a right to know what is being done with their data, but – particularly with novel machine learning techniques – it means that we need to look beyond simple calls for transparency.
Since GDPR has fully gone into effect, conversation about what exactly the implications are for data processors and controllers have been ongoing. One of them is over the “right to an explanation”. There is debate as to whether GDPR provides such a right at all. The main article (linked in the headline) discusses the difficulties in providing such a right in the context of modern ML.
This is not a settled topic, and probably doesn’t impact you today. But it’s an important topic to follow and the the authors at Open Rights Group are the most authoritative voices I’ve seen on it.
