Once GATE Overflow Telegram group was taken down because some user shared a copyrighted Aptitude book (of course it was a planned move by someone to take down all other groups in GATE domain). Now, we are sharing the Aptitude PDF compiled mainly from previous year CAT and NIELIT questions. Not yet there but soon we’ll make it GATE CSE PDF standard.

Machine Learning benchmarking is considered a difficult task mainly because there are a lot of flexible components unlike typical CPU benchmarking. By using MLCommons CK our aim is to make this difficult task as easy as possible. Over the previous rounds of MLPerf submissions more than 50% of the submissions are powered by CK and we are trying to make even more submissions during the next round (around January 2023). If you are confused what this is all about just try the below commands and if you are curious to know more then join our Telegram group.

Those interested in modular ML benchmarking can also join our WG for weekly conf-calls.

PS: Only commonsense and a system with 100 GB or more disk space is the requirement. The benchmarks should run on almost any laptop or desktop and even a Raspberry Pi. They are tested on Linux and MacOS.

python3 -m pip install cmind
cm pull repo [email protected]
cm run script --tags=app,mlperf,_resnet50,_onnxruntime  --env.OUTPUT_DIR=$HOME/final_results \
--env.CM_LOADGEN_MODE=performance --env.CM_LOADGEN_SCENARIO=Offline \
--add_deps.loadgen.version=r2.1 --add_deps_recursive.inference-src.tags=_octoml

For printing GO books for GATE CSE we have done a lot of Tikz images and they all add a layer of beauty to the GO books. To enable all CS students to draw nice Tikz diagrams for CS relevant matters we are sharing Tikz codes for all major images in this Github project. This is an initial draft and more images will be added soon.

If $user_A$ commented on a specific Answer/Question, then $user_A$ will notified via Email/Notification icon of all subsequent comments. It will be useful in most of the times but sometimes you may not willing to join in unnecessary discussions. Sadly, you can’t avoid that, On other hand $user_A$ can’t join in a discussion until $user_A$ commented on specific Answer/Question. These two features are implemented now in GO site in the form of Follow/Unfollow on every answer/question.


Thanks to @Arjun Sir
