@ShamikaRavi Do we adjust to account for inflation, i have often seen the numbers are often absolute and doesnot takes into consideration the accumulated inflation over the year, even in USD.

Happens!, but key is always to be skeptical of good results.

[Lucas Beyer (bl16) @giffmana]

So during phd a good fraction of my lab was working on semantic segmentation, which is a classic computer vision task where you assign a class to every single pixel.

The input is an image like the top one below, and the output is an 8-channel image of the same size, with each pixel a softmax vector of size 8 (number of classes in this example dataset). This is typically visualized as an image with one color per class, like the bottom image below.

Now, one day, one of my co-phd-students doing his first project in our lab got super excited! His model managed to score more than 95% accuracy! CVPR, we are coming! He started writing an email to the professor full of excitement.

Another more experienced and generally pessimistic co-phd-student was skeptical. This was too good. He requested to take a look. He looked at everything carefully, and found the bug: the code was loading the ground-truth image (the bottom image in the pic below) as input to the model! Just a couple letters wrong in the filename... Both for training as well as for testing!

The modern LLM version of this (true) story is pretty much what happened here for SWE-bench. The git history was not pruned, so the model simply looked at future commits which contain the solution. This is not the first team this happens to, btw.

The lesson here is to always be very skeptical of results that are just a tad too unexpectedly good.

Sir, @narendramodi and @jpnaddaoffice @fssai @mohfw, it's a national shame that FSSAI has consented to the request by JNTL(the Indian subsidiary of Kenvue which is a spin off of Johnson and Johnson) for a stay order to dispose of it's stock of high sugar ORSL!
Sir, not only now, in future also, except WHO recommended formula ORS, no sachet or tetrapack should be allowed in the pharmacies(including online), hospitals, and schools, as far as rehydrating medicines are concerned. ORS should never be allowed to be used on the labels except for WHO Recommended Formula ORS even if these liquids are being sold in the supermarkets and quick commerce platforms only! Trusting that you will ensure the October 15th order is implemented with urgency!

@RailwaySeva @SWRRLY Any update on Train number 07307, seems like no one has an update on the train at VSG.

Mother took this video while flying out of Delhi today.

A reminder of what shrouds us.

And what lies just above it.

@fooobar @pradeepaj Got the licence ,the address changed and the vehicle class was added later on at two different RTOs in Banglore. Process is pretty smooth
