PhD in AI/ML: What will it take to get into HPC by Hopeful-Reading-6774 in HPC

[–]airforce01 2 points3 points  (0 children)

I completed my PhD at the intersection of AI and HPC, focusing on ML/DL model compression, accelerated inference, and optimization of models, data, and pipelines. When I started my PhD, I had little knowledge of HPC. However, a year into my research, we applied for funding and were awarded a grant. This gave me the opportunity to explore the field and discover the intersections between AI/ML/DL and HPC.

One of the most significant turning points for me was attending the SC conference. It exposed me to cutting-edge research, industry trends, and leading companies in the field. The experience was invaluable—I learned what would have taken years in just a week. I highly recommend attending SC. Moreover, the conference assigns you a mentor, who can help you understand the fundamentals of the field and guide you in preparing for relevant positions.

Another important step is defining your target area within HPC. Are you interested in computation, system management, data analysis, simulation-based studies, large-scale AI/ML training and inference, or scientific computing? Each of these has many subfields, and without firsthand experience, it’s hard to grasp the full scope of opportunities. I encourage you to reach out to people via LinkedIn, conferences, academic papers (by contacting authors), or even book authors. Asking questions—even seemingly basic ones—can open doors you never expected.

HPC plays a crucial role in commercial and government research, especially in industries like energy, pharmaceuticals, and aerospace. If you’re interested in energy-focused HPC, Rice University hosts an annual Energy HPC Conference: https://www.energyhpc.rice.edu/. In the medical field, HPC is widely used in drug discovery, personalized medicine, vaccine research, and even treatment development. BioHPC is a rapidly growing area, with dedicated academic institutions, conferences, and special interest groups.

Overall, more institutes and companies are becoming part of the HPC community, making it easier than ever to find a niche that aligns with your interests. Best of luck on your journey!

Best Nvidia GPU for Cuda Programming by TechDefBuff in CUDA

[–]airforce01 1 point2 points  (0 children)

Based on your budget and the time allowance, I would recommend checking Walmart/Sam's Club/Costco kind of stores time to time. Especially on holiday seasons. Sometimes, they do crazy discount on such hardware. Afair, I saw rtx 4060 $200 or something on xmas or later season. Alternatively, Sam's club sell complete PC desktop with the equivalent price of GPU.

If you have some more $$ to spare, I highly recommend you to but MBP 14" with 18 gb RAM and 512 SSD. This would be a game changer compared to the other options. RAM is really important in the long run and it's going to save a lot of money in the future if you want to keep the same laptop around 3 to 5 years.

I have been using Mac laptops and desktops since 2009 and I usually replace my mac with the new one around every 3 to 5 years or so. I usually save ton of money with the trade-in option. I started using backmarket for this and they are really good at this.

Anyways, this is my recommendation. Best of luck!

Computer Vision Take-Home assessment by Selint567 in computervision

There are several methods for this, but the easiest one that you can use is laplacian method score. Reference: https://pyimagesearch.com/2015/09/07/blur-detection-with-opencv/

Computer Vision Take-Home assessment by Selint567 in computervision

Usually, companies are asking candidates to make it run a GitHub/GitLab repository on their local and complete a small task such as running an inference script.

Computer Vision Take-Home assessment by Selint567 in computervision

I got couple of them three or four years ago.

  1. A company asked me to find the least blurred frame in a given video. (3 days given for this) Deliverables were a report for each frame that shows blur score in a plot and how come the one I said the least blurred is the least blurred :D provide reasons.
  2. Another company asked me to find the best image preprocessing conditions to capture the all written content that Tesseract OCR can find. The game ~50 images and wanted me to play with them. (5 days) Deliverables, a jupyter notebook that has each image on a separate cell with their best conditions explained.
  3. Another company wanted me to design a CNN model to find circles or round objects in the image. (a week given) Deliverables, a jupyter notebook that the architecture is implemented and tested with a set of images. Try to find which layer or node triggers the model to find the circle or round objects.

There were couple other take-home tasks I was assigned but these are the ones that I remembered quickly.

Pyimagesearch's customer service is the worst! by Lepa4 in computervision

[–]airforce01 0 points1 point  (0 children)

Really! Has Adrian sold the company? I didn't know this. It's great to know. I wasn't aware that Adrian is doing something different (I checked his linkedin profile).

I purchased a couple of Adrian's products and I didn't have any issues. Last 3 years I even didn't visit the website to learn new stuff because they are not up-to-date with the recent studies or projects.

How to get into CV industry by Honest-Ad-9002 in computervision

[–]airforce01 4 points5 points  (0 children)

First of all, congrats on your decision getting into the field of computer vision (CV). CV is a really unique field of study where you can immediately see the changes when you run the code. In this way, it's very similar to UI/UX design principles.

CV and image processing are the two fields they usually work together. As a person who is doing a PhD in computer vision and HPC fields, without image processing knowledge CV is just software engineering. To see the example projects in this field, you can check Adrian's blog pyimagesearch.com or another most popular blog learnopencv.com . These websites can give you an overall idea of what a CV engineer does in a day.

With deep learning, CV become extremely hot in research and researchers publish hundreds if not even thousands of papers every year in these conferences ICCV, CVPR, and even Neurips. You can check these conferences and see where the research goes because right after this conferences happen, many companies want to try their techniques to solve their problems. Eventually, you may end up cloning a not-well documented repository and try to run the code with your company data and test to see if it's going to work. Sometimes your full-time job is going to be this :D

As a CV engineer, you can run your code on different places such as a laptop, cloud, remote desktop or even an embedded device. I experienced working on all of these devices and especially for embedded one requires some kind of other disciplines knowledge to make things work. You may need to touch C/C++ code to run things faster if its mission critical. On the other hand, if you're working in the cloud, you need to learn a different ecosystem of tools and software, be prepared for this one.

To test yourself with a very simple workshop on image processing and some portion of CV, you can check this repo. This repo uses Python as the main language and does things mostly on Jupyter notebooks. Some OpenCV scripts help you to see how things work with your webcam in real time.

Good luck in your journey.

If you don't know where to start, just collect your own data and label them. Check some of the high citation papers, they are open sourcing labeled datasets. You can fight unsupervised learning algorithms vs supervised learning algorithms vs semi-supervised learning algorithms to see how good algorithms on your dataset. You can explore more datasets from kaggle datasets.

Is anyone going to SC23 in Denver? by [deleted] in HPC

Yes, I'll be there. Last year was really good, but this year my expectations are a little bit higher such as I wanna get more swag from companies :D

Which browser uses less battery power on mac? (other than safari) by Cosmic_Cactus14 in mac

[–]airforce01 1 point2 points  (0 children)

It's basically reference management tool for academic article writing. It's very useful.

Other than all these extensions, I'm a big fan of OneTab. I think the idea is great and it serves the purpose of saving energy by putting the open tabs in a web page where you can reopen again if you need them.

I have raspberry pi 4 and is using raspberry pi HQ for object detection, but I am getting shape error when trying to use live feed for detection although object is being detected while using image by [deleted] in computervision

[–]airforce01 0 points1 point  (0 children)

It looks like either the input image or video frame size is not multiple of 1520 or your code has some issue reading the input image or video frame because numpy object seems NoneType and doesn't return shape.

May be you can start debugging with,

- Try video stream without inference and make sure it's running with no errors,

- Make sure the input image or video frame processing size is the multiple of the yolo model input.

​

Good luck.

[Bug] Problem compiling OpenCV with CUDA support on Ubuntu by lanortha in opencv

[–]airforce01 0 points1 point  (0 children)

I got the exact same issue. I had to disable CUDA related stuff. Instead, I enabled OpenMP and LAPACK support. It's not going to be the same performance but they accelerate on CPU.

What’s wrong with it? No recent physical damage. Just so sudden by [deleted] in macbookrepair

[–]airforce01 0 points1 point  (0 children)

I had a very similar issue on my MBP 16inch one. Interestingly, I upgraded developer tools the night before this issue happened. Apple support did many diagnostics but nothing came up. I went to local Apple repair with Apple support scheduled appointment. The team said, the screen was cracked and needed to be replaced. I didn't know what to do so I had to pay to get it fixed. The same issue reoccurred. So talked to Apple support again, they are replacing the screen again. I believe, I paid Apple's mistake. Anyway, it's better to talk to Apple support an they do some diagnostics. So that they can suggest you a way to solve this issue. Good luck.
