Repeating yesterday’s route aiming for making a PR on 10K, and this happened… 💩

(so my 10K PR remains to be 50:51)

1/ In this age of LLMs and generative AI, do we still need knowledge graphs (KGs) as a way to collect and organize domain and world knowledge, or should we just switch to language models and rely on their abilities to absorb knowledge from massive training datasets?

1/

When performing reasoning or generating code, do #LLMs really understand what they’re doing, or do they just memorize? Several new results seem to have painted a not-so-rosy picture.

The authors in [1] are interested in testing LLMs on “semantic” vs. “symbolic” reasoning: the former involves reasoning with language-like input, and the latter is reasoning with abstract symbols.

If a powerful #LLM is told that “Daphne Barrington is the director of A Journey Through Time”, it would surely be able to answer the question “Who is the director of A Journey Through Time?”, right? Well, according to a recent paper [1], not quite (screenshot).

Solving causal #reasoning tasks is a hallmark of intelligence. One recent study [1] categorizes these tasks into covariance-based and logic-based reasoning (screenshot) and examines how #GPT models perform on causal discovery, actual causality, and causal judgments.

This explains why sometimes someone favorited/reposted my post, when I clicked on their profiles, I didn’t get to see their posts. The end result is, I don’t feel informed enough to follow them, which I think discourages Mastodon users from expanding their circles.

My dear #running / #trailrunning friends: I need to ask for advise on picking #shoes for #marathon runs on paved roads and mildly unpaved trails (photo 1):

1. ASICS Trabuco Max 2 (photo 2): the middle in weight (~290g), not waterproof. Bouncy w/ rocker design.
2. Salomon Speedcross 5 (photo 3): the heaviest (~295g), waterproof(?). Big lugs.
3. Nike Pegasus Trail 4 GTX (photo 4): the lightest (~270g), waterproof. Smallest lugs.

Do you have experience w/ any of these? What would you pick?

ArXiv.org has been a wonderful place for researchers to submit findings and catch up with the latest, but does submitting papers there (“early ArXiving”) increase the odds for them to be accepted later in a peer-reviewed venue?

Upcoming #Seattle #HalfMarathon:

• Ascent: 984 feet (35.6% of the route uphill)
• Descent: 990 feet (43.2% of the route downhill)
• Flat: 21.2% of the route
• Steepest uphill: +25.6% (at 11.18-mile mark)
• Longest uphill: 1.01 miles (at 8.61-mile mark)

I ran some of this route before and it was pretty challenging to me…

1/ Alright -- here is my not-so-good, pretty-bad weekend's 16.3-mile report:

• On Saturday I finished my 35th 5K #Parkrun 25:20, almost 2 minutes slower than my PB (23:21) just a week ago! I even stopped to walk 3 times during the run, which never happened before!

• On Sunday I finished my 11th half #Marathon 2:10:58, almost 20 minutes slower than my fastest (1:51:48) just a month ago!

BenjaminHan, 8 months ago to LLMs

1/ How robust and reliable is the code generated by #LLMs, especially for real-world software development? A recent work [2] constructed a new benchmark based on [1] to evaluate if the generated code uses API correctly. Four popular #LLMs -- #GPT3.5, #GPT4, #Llama2, and #Vicuna -- are tested, and #GPT4 under zero-shot scored 62.09% misuse rate. Even with one-shot relevant examples the misuse rate of #GPT4 is 49.17%.

1/ This weekend's 16.3-mile report (total time/pace):

• 5K #Parkrun: 24:19/7'50", slower by 24 seconds than last.
• Half #Marathon: 1:54:50/8'46", faster by 5 minutes than last.

All-time-best are still:

• 5K: 23:51/7'41"
• Half Marathon: 1:51:48/8'32"

Done with today's #Seattle Half #Marathon! Woke up at 5am, left home at 6am, arrived at Seattle Center at 6:30am, started the run at 7:30am, and finished in 1:56:21 (pace 8'53")!

I was 936 of 3112 overall, and 42 of 189 in my age group!

Earned my #HalfMarathon PR today on the beautiful #SammamishRiverTrail (SRT): time 1:48:25 pace 8'16”/mile according to #Strava. My watch again generously claims time was 1:42:49. I picked Strava to be the record.

Temp feels like 50F, dew point 47F, cloudy w/ breeze 3.2mph SW. In other words, perfect weather to get PR!

Today I ran my 2nd #marathon practice run this month with my son riding his bike with me! Weather was cool with a bit of drizzle at the end, temperature was 55F (12.8C) w/ dew point at 53F.

Distance was 26.27 miles, moving time was 4:11:50, and pace was 9’35”/mile. This is 22+ minutes faster than a couple weeks ago!

9.37 miles easy run @ #SVT, also testing another pair of #shoes: ASICS Gel-Nimbus 25. Result is not good: the lateral side of my right foot hurts after the run (not during)! I blame it on the high stack of cushioning: my theory is my natural reflex to counterbalance the unevenness of the trail surface is interfered/distorted by the cushioning. Does that sound plausible?

Got my #15K PR in my dusk run in the park: time 1:17:51 pace 8’21”/mile! Getting ready for the early March #HotChocolateRun in #Seattle!

Although there’s still a lot of room for improvement, I’m proud that I can actually speed up my pace now into the run! And this was done after a heavy meeting day at work started at 8am!

Bonus: I got a heart award on this special day!

5th time is the charm: I finally cracked my 1st sub-4h #marathon today! Moving time was 3:50:33, pace 8’48”/mile. For each half I was actually faster than my best official #halfMarathon PR (1:55:16 < 1:56)!

Weather was typical #Seattle: nagging drizzle. Temperature feels like 40F (4.4C) w/ wind 7 mph (S). Thanks to my son on the bike (he came even when losing 1 hour sleep to #DST change), we performed no-stopping fueling twice, and I only brought two gel packs on me w/o phone.

My first #marathon #race, done! Official result was 3:51:39.8, pace 8'50"/mile. I was ranked overall 50/167, in males 40/102, or in my age group 5/9. This is slightly slower than my PR in practice (3:50:33, pace 8'48”).

But the official time didn't account for the three times I was lost (!) and had to either retract or asked people (I was not the only one). According to my watch I earned PR on marathon: 3:44:58, pace 8’35”, and #halfMarathon: 1:45:19, pace 8’02”. (1/2)

Perhaps a bunny helped me today 🐇? After last Sunday's #marathon race PR, on my 50th #Parkrun 5K today I made my third PR this year: time was 22:33, pace 7’16”! This is 34 seconds faster than my last PR!

This completes my 2nd goal in 2024: earn 3 PRs in Parkrun!

One of the stretch goals in 2024 is now accomplished! I got my latest PR in today's #Parkrun 5K: 21:38 at pace 6'57"/mile, thus reaching my goal of getting sub-7' pace!

Going in I was pessimistic because of the jet lag. Turns out running uphills with 1300ft elevation gains in #Sintra #Portugal paid off!

Next up: finish 5K in under 21 minutes!
