this is wild — kNN using a gzip-based distance metric outperforms BERT and other neural methods for OOD sentence classification
intuition: 2 texts similar if cat-ing one to the other barely increases gzip size
no training, no tuning, no params — this is the entire algorithm:
![for (x1, _) in test_set: Cx1 = len(gzip.compress(x1.encode())) distance_from_x1 = [] for (x2, _) in training_set: Cx2 = len(gzip.compress(x2. encode()) x1x2 = " ".join([x1, x2]) Cx1x2 = len(gzip.compress(x1x2. encode()) ncd = (Cx1x2 - min(Cx1,Cx2)) / max(Cx1, Cx2) distance_from_x1.append(ncd) sorted_idx = np.argsort(np.array(distance_from_x1)) top_k_class = training_set[sorted_idx[:k], 1] predict_class = max(set(top_k_class), key=top_k_class.count)](https://pbs.twimg.com/media/F05HxqsWwAAHRCI.jpg?name=orig)
ALT for (x1, _) in test_set: Cx1 = len(gzip.compress(x1.encode())) distance_from_x1 = [] for (x2, _) in training_set: Cx2 = len(gzip.compress(x2. encode()) x1x2 = " ".join([x1, x2]) Cx1x2 = len(gzip.compress(x1x2. encode()) ncd = (Cx1x2 - min(Cx1,Cx2)) / max(Cx1, Cx2) distance_from_x1.append(ncd) sorted_idx = np.argsort(np.array(distance_from_x1)) top_k_class = training_set[sorted_idx[:k], 1] predict_class = max(set(top_k_class), key=top_k_class.count)
this paper's nuts. for sentence classification on out-of-domain datasets, all neural (Transformer or not) approaches lose to good old kNN on representations generated by.... gzip aclanthology.org/2023.findin…

Here are the extraordinary 1st results from #MTGI1's Lightning Imager!⚡️
We can now for the first time detect lightning over Europe & Africa👏
Watch here: youtu.be/wjNq-xMWE28
Please note: These animations were created from raw preliminary data and are not for operational use.

The 1-minute Infrared images with an overlay of #GLM Flash Extent Density showed abundant lightning activity associated with this Mesoscale Convective System: cimss.ssec.wisc.edu/satellit… #IAwx #MOwx #ILwx

Reminder: If you've used MetPy, we'd love for you to take our 2023 User Survey, which closes at the end of the week. This should only take 5-10 minutes and is really important for guiding our work and reporting to our NSF sponsor. forms.gle/s312GsEjGFR2p1os6

Are you ready to be thunderstruck?
We will soon reveal the first results from #MTGI1’s Lightning Imager! ⚡️
This is the FIRST EVER 🛰️ instrument designed to detect lightning over Europe & Africa!
Save the date and join @eumetsat, @esa & @LDO_Space next week to find out more 👇

As we always do at the start of #LightningSafety Awareness Week, let’s start with a spelling lesson to remind you what we’re talking about this week. It’s #lightning. #LSAW23

Supercell + high speed camera = awesomeness at 100,000fps! Here’s a CG with multiple return strokes. #okwx #lightning

Hey! We have a session! Sarah Bang, @WxSarahS , and I are convening a session @theAGU annual meeting on Advancements in Lightning Meteorology, the session info can be found here:
agu.confex.com/agu/fm23/prel…
It's a co-organized session with ASE and Atmospheric Sciences.

One reason to have multiple lightning datasets when working decision support for #LightningSafety. This lightning flash is real but mislocated. Radar, satellite, GLM, and LMA all do not support lightning is this area of #tnwx near Lawrenceburg

Good day at Texas Tech for a good presentation on lightning research among other things. Thank you Dr Kelcy Brunner.

My first upward lightning strike captured. Single 25sec exposure. This was taken around 11pm West of Slaton, looking West to the South of Lubbock, Texas @NWSLubbock #TXwx

Happy to announce that I'll be continuing studies in atmospheric electricity (TRACER and Phased-Array Imaging Radars!) at @Atmo_TTU as an RA under @deeplycloudy!
Excited for the future, gig'em and guns up!
