China:
- We use ConvNets to diagnose COVID19.
- We build a hospital in 10 days.

USA:
- Our hiring freeze left 700 positions at CDC unfilled.
- Our COVID19 test doesn't work.
- We stop our experts from talking to the press.
- The whole pandemic thing is a hoax anyway.

Brain function relies on circuits of spiking neurons with synapses playing the key role of merging transmission with memory storage and processing. Electronics has made important advances to emulate neurons and synapses and brain-computer interfacing concepts that interlink brain and brain-inspired devices are beginning to materialise. We report on memristive links between brain and silicon spiking neurons that emulate transmission and plasticity properties of real synapses. A memristor paired with a metal-thin film titanium oxide microelectrode connects a silicon neuron to a neuron of the rat hippocampus. Memristive plasticity accounts for modulation of connection strength, while transmission is mediated by weighted stimuli through the thin film oxide leading to responses that resemble excitatory postsynaptic potentials. The reverse brain-to-silicon link is established through a microelectrode-memristor pair. On these bases, we demonstrate a three-neuron brain-silicon network where memristive synapses undergo long-term potentiation or depression driven by neuronal firing rates.

Quick tutorial on how to test the online artificial intelligence based coronavirus2019 CT scan detection tool (released Feb 26, 2020):

1. Hit English to provide translation of website:

https://121.40.75.149/znyx-ncov/index#/app/online_try

2. Download ct scan images from covid19 research papers, like this one (take note whether the downloaded image represents covid19 positive cases, as labeled on website):

https://images.rsna.org/index.html

3. Crop the image in paint, i.e. remove the black sides to the left and right of the image, leaving only picture of lungs in center. (Maybe I'll write up a simple Ui to do this cropping automatically)

4. Load ct scan images in website. (Up to 9 images)

5. Wait a few seconds (On 50mpbs internet connection, may be more waiting time on slower connections)

Results: Look for red boxes in resulting image on right hand side.

6. Optionally, you can also load the same ct images in another ai based pneumonia detection tool I prepared (Feb 9, 2020): https://github.com/JordanMicahBennett/SMART-CT-SCAN_BASED-COVID19_VIRUS_DETECTOR

It is advised that governments subsidize Ct scan price if possible, and advise scan personnel in contact with potential covid19 patients, be properly protected. Notably, China has performed thousands of scans. The control of this virus could reasonably save economy far more than cost of ct scan subsidy in the long run (i.e. help prevent mass shutdown of businesses/schools etc).

Postdoc position in ML/stats at the University of Chicago

Applications are invited for a postdoctoral researcher working under the supervision of Prof. Bryon Aragam in statistics, machine learning, and/or optimization within the Econometrics and Statistics group at the Booth School of Business of the University of Chicago. Potential candidates should have a background in statistics and machine learning, for example nonconvex optimization, nonparametric statistics, and/or learning theory. Applications of interest include causal inference, representation learning, personalization, and graphical models, but may also depend on the candidate’s individual research interests. There will be an emphasis on theoretical/mathematical problems as well as computational/applied work, with a particular focus on problems at the intersection.

The Econometrics and Statistics group at the University of Chicago is diverse and rapidly growing, with 12 full-time faculty working in diverse areas such as statistical machine learning, causal inference, Bayesian statistics, financial econometrics, and forecasting.

Qualifications
The candidate should have a recent Ph.D. degree (or all-but-dissertation) in statistics, computer science, mathematics, or a related area, and should be proficient in programming in Python or R. We welcome applications from candidates with diverse and/or nontraditional backgrounds.

To Apply
Interested candidates should email [email protected] to indicate their interest in this position.

Required Documents
1) Resume/CV
2) Cover letter, including brief description of research interests
3) Graduate transcripts
4) At least one academic reference
