Should we regard #AI as a single system, or as one part of a larger economy of people and models? Michael I. Jordan, a UC Berkeley professor, argues for the second. Billions of people supply the data and billions use the systems, so he would design AI the way economists design markets. He […]

Today I ran the same EZ 4mi as yesterday: same Elliott Bay route, same lunchtime start, solo, capped by HR 135bpm. Wednesday, 57°F and overcast: pace 9'00"/mi, HR avg/max 131/145, EF 1.36 m/beat, decoupling 2.5%, splits 9:11→8:46. Thursday, 59°F in the fog […] [Original post on sigmoid.social]

Thick fog drifting between downtown Seattle towers, seen from a high office window late Thursday morning, with a long straight road running away below and rooftop fans in the foreground.

The sun as a pale white disc behind fog, in a smooth blue-grey sky, just after the run.

Two runs side by side, both out and back on the Elliott Bay Trail in Seattle. Left, Wednesday Oct 7 at 11:42, overcast: route map with an HR-colored track above an HR and pace chart, HR average 131, max 145 at the very end. Right, Thursday Oct 8 at 11:45, in fog: the same route, starting a little further south, above its HR and pace chart, HR average 131, max 146 at the very end.

Per-mile tables and pace bar charts for the two runs on one pace scale, each chart labeled with the run's HR avg/max, 131/145 on Wednesday and 131/146 on Thursday. Wednesday: 9:11, 9:06, 8:58, 8:46 at HR 126, 130, 133, 135. Thursday: 9:09, 8:55, 8:48, 8:31 at HR 125, 131, 133, 135. Both speed up every mile, and Thursday runs each mile faster at the same heart rate.

I had a chance to tease out the effect of running and talking in the past two days. I ran EZ 4mi each day in this taper week, both capped by HR 135bpm. Tuesday talking with a friend: pace 9'03"/mi, HR avg/max 136/143, EF 1.30 m/beat, decoupling 2.8%, a […] [Original post on sigmoid.social]

For runners out there going to #Snohomish River Run #marathon next Sunday, here are annotated maps I built: the north leg out to the high point at mile 5.1 and back through town, then the flat river leg out to the turnaround at 18.3 and home. All 12 aid […] [Original post on sigmoid.social]
