IndoML Symposium aims to bring together students and young researchers to interact with leading researchers across the globe with the theme of “AI for Data and Data for AI”, focussing on how new AI problems are inspired by novel datasets, and how AI techniques help collect new datasets that can impact our understanding of the world around us.

They have an excellent list of eminent expert speakers who exemplify different aspects of the IndoML 2021 theme. The full list of speakers and the schedule can be found here: 

The event will be held virtually, and registration is free but mandatory. Registration for the IndoML Symposium is open through December 15th, 2021.

We now have mention (type @username) option in comments for both questions as well as blogs. This is restricted to only those whom you favorite – that is, if I favorite users A, B and C only those 3 can mention me in comments. So, if you are running a class and wants only your students to mention you, just add them into your favorite users lists – star button on the user profile.

Official mlcommons inference results for Round 1.1 was released on September 22. The official results are in the form of spreadsheets. So this task is to generate the best summary report for mlcommons results. 

Just some background

Mlcommons inference submission is like the Olympics for AI hardware/software vendors where by they demonstrate their performance in a peer reviewed manner. 

Submission Divisions

  • Closed (More restrictions and guidelines to be followed and provides an opportunity for hardware comparisons)
  • Open (More relaxed and aimed at showcasing specific hardware/software optimizations)
  • Both the above are possible with and without power measurement

Submission Categories

  • Datacenter (Offline (throughput) and server (load handling when input arrives in a Poisson distribution fashion) scenarios compulsory for closed division)
  • Edge (Offline and Singlestream (average latency for a single query) compulsory for closed division)

For this task we will focus ONLY on Closed division.

  • Metric to be considered: “Samples/s” (Singlestream Latency need not be considered)


  1. ResNet
  2. SSD-small (Edge only)
  3. SSD-Large
  4. 3D-UNet
  5. RNN-T
  6. BERT-99
  7. BERT-99.9 (Datacenter only)
  8. DLRM-99 (Datacenter only)
  9. DLRM-99.9 (Datacenter only)

So, 6 benchmarks in total for edge and 8 benchmarks in total for datacenter.

So, we’ll have the following comparisons (44 in total) for Samples/s

  1. Datacenter Offline with Power * 8
  2. Datacenter Server with Power * 8
  3. Edge Offline with Power * 6
  4. Datacenter Offline without Power * 8
  5. Datacenter Server without Power * 8
  6. Edge Offline without Power * 6

More Info:

Additional Metrics to be Considered

  1. Performance per Watt (only under Closed-Power and so 22 comparisons in total)
  2. Server/Offline Ratio (8 with power and 8 without power)

Hence in total we’ll have 44 + 22 + 16 = 82 comparisons for Version 1.1

Historical Best

For this we need to consider results of all the 4 rounds which have happened so far (0.5, 0.7, 1.0 and 1.1) and consider the data together. Some scenario might have changed across the rounds – Server scenario not in v0.5 for example) and can be ignored. So, this will also produce 82 comparisons as like for Version 1.1. Thus in total we’ll have 164 comparisons. 

Some constraints for the comparisons

  • For a given Accelerator, we consider only the best score (whichever row gives the maximum metric value which can change as per the “metric” used for comparison) and ignore all other results using the same accelerator
  • For each comparison graph, we need to compare the (up to) top 10 values (top 10 accelerators) with the X-axis showing just the accelerator name (like NVIDIA A100-PCIE-40GB) but also linking to the submission ID like “1.1-006” (can be in an additional table) so that other submission details can be looked at  

Presentation of Results 

  1. The results must be presented ordered by benchmark and then by category then by “with/without” power. For example, for Reset we will do as follows:
    1. Offline Samples/s for Datacenter w Power
    2. Performance per Watt for Datacenter Offline
    3. Server Samples/s for Datacenter w Power
    4. Performance per Watt for Datacenter Server
    5. Server/Offline for Datacenter w Power
    6. Offline Samples/s for Datacenter without Power
    7. Server Samples/s for Datacenter without Power
    8. Server/Offline for Datacenter without Power
    9. Offline Samples/s for Edge w Power
    10. Performance per Watt for Edge Offline
    11. Offline Samples/s for Edge without Power
  2. The results can be presented either in HTML form or PDF
  3. Scripts to produce the results –  please make them available in Github and email your results including the Github link with README to reproduce the results, to “[email protected] dot com” 


  1. Presentation of results will have high consideration for contest evaluation
  2. Automation is the key – if you try to do this task manually you are more likely to fail
  3. Unfortunately there’ll be only one winner but this task will make you learn a lot. And the winner will get Rs. 15000 cash prize from GATE Overflow. If equally good submissions are made prize money will be shared.
  4. Any clarification regarding the contest – please comment under this blog
  5. Deadline for submission: 9:00 pm IST, October 3

Mlcommons v1.1 Submission Results can be viewed at the following links (use the dropdown for Other rounds)

We are happy to announce that GO Classes (formed by GATE Overflow senior members Sachin Mittal and Deepak Poonia), in collaboration with GATE Overflow, is launching GATE 2022 Complete Course. Yes, no more complaints that there is “no personal” attention in GATE Overflow for GATE aspirants. 

Course Details:

  • Live Lectures: All the classes will be live interactive classes, where you can learn, interact with faculty, ask your doubts live. 

  • Commencement of classes: Classes will start from 26th July 2021. Classes Schedule will be shared in advance.

  • Recordings of lectures: ALL the live lectures will be recorded as well and can be watched anytime after the live class. 

  • Course Duration: From 26th July to 15th December. 

First Subject that will be taught is Discrete Mathematics. It will start on 26th July 2021. 

Discrete Mathematics and C-Language subject classes are FREE for all. 

Course Features:

  • Interactive Classes: All the classes will be live interactive classes.

  • Live Doubt Discussion: After every class, we will have live interactive doubt discussion.

  • Homeworks: For EVERY lecture, on the same day, Homework will be provided. This homework will contain several questions, covering all the topics/concepts of the respective lecture. Solutions to the homework will be provided the next day.

  • Weekly Quizzes: Every Week, on the Off day, we will have a Quiz for the ongoing subject. It will help you evaluate your preparation and learning.

  • We will make following Standard Books Easy. Our lecture notes, homeworks, practice sets etc will be based on standard books and resources. Everything will be taught from basics, with many examples to understand the concept clearly.

Instead of preparing themselves for M.Tech courses at IITs some of those who got good rank in GATE have been seen promoting their stuffs and even sharing referrals to coaching institutes. For any serious candidate preparing for GATE all information should be available in the GO blogs given below and many aspirants have even shared their full preparation experiences. Still many will be looking for “spoon feeding” and if you want to help them you can do at your own place – not here. By sharing your notes if you believe you are helping aspirants – 99% you are not.

You can now add subject filtering in Pragy’s App to view your marks excluding any set of subjects and also see the set and normalized ranks with the selected filter. This way you can identify the subjects where you performed the best and not so the best. Try it now…

Suggestions welcome...
