Whilst most Kagglers are engaged in XGBoosting and ROC AUCing on toy competitions with fake (aka synthetic) data and fake metrics a nugget of gold by Donghun Lee has gone unnoticed by Kagglers. #conformalprediction

Say u r trading a volatile stock. You notice (1) flurry of small buy limit orders at $50, followed by cancels (2) persistent 10K share offer at $50.10 keeps refreshing (3) sporadic market sells hitting bids at $49.95 Hypothesize & extract information in this scenario?

Something has broken tonight in the bond market. We are seeing a disorderly liquidation. If I had to GUESS, the basis trade is in full unwind. Since Friday's close to now ... the 30-year yield is up 56 bps, in three trading days. The last time this yield rose this much in 3

o4-mini-high is the first AI to pass my personal secret benchmark for hallucinations and complex reasoning, so I guess now I can tell you all what that benchmark is. It's simple: I post a complex midgame chessboard and 'mate in one'. The chessboard does not have a mate in one.

Everyone is a “quant” now! Well, tradecraft remains the soul of systems engineering. LLMs are powerful aids, but they’ll never replace the hard-won mastery of detail—minutiae forged through time, grit, and rigor. Use tools, but trust the craft that only comes with time.

If you are really curious about RL and tearing your hair out on (oh, so many things!) and still care about the rubber meeting the road, I HIGHLY recommend you follow Joseph Suarez (e/🐡) and sign onto the discord channel.

(Training Data > Degrees of Freedom) + Low Training Error = Low Test Error (Guaranteed). Most people neglect this and plod on.
