TL;DR: Making reward local prevents interference, but it also breaks deep credit assignment: reward can’t reach early layers before eligibility traces evaporate.

TL;DR: Part 2 gave the owl a plasticity governor: when timing is noisy, stop learning.

TL;DR: Part 2 gave the owl a confidence governor: when timing is noisy, stop learning.

TL;DR: Noisy timing makes STDP thrash.

Extending it to a Time Coded Ripple Carry Adder Let’s stretch this into a time coded ripple carry adder.

The amber liquid swirls in the glass.

In the last post on neural logic gates, I treated a spike like a yes or no question.

As you may have read, I’ve been thinking about some crazy ideas related to neurons lately.

iuSTDP is designed to handle order uncertainty.

When you’re thinking about how to build a world brain, you end up with a huge bag of shifting unsolved problems.

The amber liquid swirls in the glass, rye catches the light like neurons firing.

There’s an announement for a new stream processing system tonight.

Introduction Although Terraform seems to be the current front-runner in the infrastructure-as-code department, I've recently run across Pulumi as an excellent alternative.

Here’s a picture that summarizes what I’ve been obsessing over for the past 7 months: As you can see, I’ve learned to take pictures with better lighting (and lost a bit of weight). [10:05] Nice Work!!!

Introduction Apache Kafka is a distributed and decentralized publish and describe system.

I've recently done some work on a very rough prototype of a Mesos scheduler for Samza.

This is a repost of an article I wrote for LinkedIn's engineering blog.

Note: You may want to read the the Paxos paper, the Raft paper, the Chubby paper, the Spanner paper, and the F1 SQL layer paper before trying to read this -- it won't make sense unless you're familiar with the concept of multiple consistency domains.

A side project I’ve been working on for some time now is a decentralized-distributed file copy tool in the spirit of the typical cp command you can find on just about any unix style system out there.

I haven’t been able to find much information on how space filling curves, like Hilbert curves, are used in network interconnection topology in supercomputers.
