[D] DeepMind’s breast cancer screening does cite the earlier NYU work with ‘small, enriched datasets with limited follow-up’ critique

[D] DeepMind's breast cancer screening does cite the earlier NYU work with 'small, enriched datasets with limited follow-up' critique

For those wanting to juxtapose the breast cancer screening work published by Deepmind with the earlier work published by the NYU team, the Deepmind paper does cite the NYU paper (twice) and here is the context in which the citations appear:

A few studies have characterized systems for breast cancer prediction with stand-alone performance that approaches that of human experts[29,30]. However, the existing work has several limitations. Most studies are based on small, enriched datasets with limited follow-up, and few have compared performance to readers in actual clinical practice—instead relying on laboratory-based simulations of the reading environment. So far there has been little evidence of the ability of AI systems to translate between different screening populations and settings without additional training data[31]. Critically, the pervasive use of follow-up intervals that are no longer than 12 months [29,30,32,33]

[30] Wu, N. et al. Deep neural networks improve radiologists’ performance in breast cancer screening. IEEE Trans. Med. Imaging https://doi.org/10.1109/TMI.2019.2945514 (2019).

Can someone with any sort of radiology background here comment on the ‘ follow-up intervals’ part?

Pro-tip: The nature paper is not exactly behind a paywall (unless you try and access it via their main portal) and one can access the pdf via this page:

[R] Acoustic, optical, and other types of waves are recurrent neural networks!

Paper: Open access in Science Advances

Code: Available on GitHub

Lately, there has been a lot of cross-pollination of ideas between different areas of physical and numerical science and the field of machine learning. This has lead to interesting demonstrations of optimizing physical models using machine learning frameworks, but also to the development of a number of exciting new machine learning models (e.g. neural ODEs, Hamiltonian neural networks, etc) that borrow concepts from physics.

My group has been particularly interested in the view point that physics itself can be used as a computational engine. In other words, we’re interested in physical systems that can serve as hardware accelerators or as specialized analog processors for fast and efficient machine learning computations.

In our paper that was recently published in Science Advances (open access) we have shown that the physics of waves map directly into the time dynamics of recurrent neural networks (RNNs). Using this connection, we demonstrated that an acoustic / optical system (through a numerical model developed in PyTorch) could be trained to accurately classify vowels from recordings of human speakers. Essentially, we launched the vowel waveforms into the physical model and allowed the optimizer to add and remove material at 1000’s of individual points within the domain, essentially acting as the weights of the model.

Because this machine learning model actually corresponds to a physical system, it means that we could take the trained material distribution and “print it” into a real physical device. The result would be something like an ASIC (application specific integrated circuit), but for a specific RNN computation. We’re really excited about these results because they point to being able to perform complex recurrent machine learning calculations completely passively, with no energy consumption, aside from the energy carried by the pulse itself.

New Online Course Gets IT Up to Speed on AI

Enterprise use of AI has grown 270 percent over the past four years, according to a 2019 survey of CIOs by Gartner.

To stay competitive in the face of this rapid adoption, organizations need to build data center infrastructure that is scalable and flexible enough to meet quickly evolving and expanding AI workloads.

IT plays a critical role in this. IT professionals across data center management, development operations (devops), security compliance and data governance need to be set up for success.

To help, the NVIDIA Deep Learning Institute has released an online, self-paced Introduction to AI in the Data Center course designed for IT professionals. (Enroll today — the course is free through Jan. 31 with code DLI_IT_BLOG_PROMO.)

The course explores AI concepts and terminology, NVIDIA’s AI software architecture and how to implement and scale AI workloads in the data center.

In this focused four-hour course, IT professionals will understand how AI is transforming industry and how to deploy GPU accelerated computing in the data center to facilitate this capability in their own organization. Plus, participants will earn a digital badge of completion to support their professional growth.

For enterprises considering how to get started with the right resources and training to support their needs, this course will get your IT teams started on the right foot. At a high level, the course covers:

  • GPU Computing in the Data Center
  • Introduction to Artificial Intelligence
  • Introduction to GPUs
  • GPU Software Ecosystem
  • Server-Level Considerations
  • Rack-Level Considerations
  • Data Center-Level Considerations

The Deep Learning Institute offers hands-on training in AI, accelerated computing and accelerated data science. Developers, data scientists, researchers, students, and now IT professionals can enroll in DLI courses to get the practical experience they need to learn how to deploy AI in their work. To date, the DLI has trained more than 200,000 people.

Enroll in the “Introduction to AI in the Data Center” course for free with code DLI_IT_BLOG_PROMO before Jan. 31.

[Discussion] Resources for data architecture design for enterprise to support data science/ML

[Discussion] Resources for data architecture design for enterprise to support data science/ML

Hello,

I am looking for resources (books, blogs, courses) to learn more about designing data architecture for enterprise that supports executing data science projects at scale. I realize the importance of having an architecture that supports rapid experimentation, data access/abstraction, security baked in, while also being scale-ready whenever projects are ready for production.

Are you aware of any such resources? Have you read a book/blog that helped you with these questions for the enterprise you support? Thanks for your help!

[P] Building a community on Artificial Intelligence for Life Sciences

It’s no secret that ML and AI can deliver a great value in Life Sciences.

I have spent past 10 years as a researcher in the field of Computational Biology working very close to wetlab.

Now, together with a lovely bunch of peops, I am building virtual community dedicated to AI in Life Sciences in the format of a not-for-profit organization. We now unite several people working in the field in the UK and Switzerland. The mission: share tech expertise, code, links and papers.

For the sake of experiment at the moment we are running fully from a telegram channel, come have a look at https://ails.institute and join us! All ideas are welcome!

[D] Please suggest me material fo maths

I want to deeply understand maths related to deep learning and machine learning. I am mentioning my background so someone can suggest me some materials for learning purpose.

Backgroud: Undergrad completed.I have completed deep learning specialization. I can calculate derivation of different things like sigmoid and thanks to deep learning specialization, i also know how actually neural network work. I have also implemented few research paper on my own and open sourced the code.

But, now i want to re-learn calculus, linear algebra and probabilities for better understanding of dl and ml methods. Why we choose sigmoid or tanh, how actually relu is implemented and how actually auto-grad works. things like that.

I searched for some book on calculus and linear algebra but recommendations are to off. Many people recommended Spivak and i started reading it. but starting chapter looks too much dull and only explains theoretically. I want materials where i can understand thing pratically. If possible, then with programming exercises.

please suggest for calculus, LA and Stats.
