Welcome to Data Scientists's Private Community

Researchers followed the signal from the wastewater treatment plant through the sewage system, checking various manholes along the way. After sampling about 50 manholes, they pinpointed the source to a single building housing a company with about 30 employees. 

I did some more research and apparently for signal tracing and hypothesis testing a ton of data sampling techniques were utilized here. Especially, sub ground sampling techniques and kriging to interpolate the directions to investigate more samples. This is because genetic sequencing is a very costly process. This is how they were able to do only 50 samples between the wastewater plant and the building where Patient Zero was working.

[Interesting Read] Using Data Science to track a rare COVID-19 variant- Grapevine

Extremely interesting take on analyzing tock volatility through internet data. Here are some of my insights from this:

1. The approach is quite novel as it utilises custom metrics from social media and search trends as predictors in a GARCH model. It is a fairly unique way of determining the impact of public sentiment on financial markets.

2. It is quite relevant as the impact of COVID-19 pandemic on the stock market is clearly agreed upon, with severe correction in airline stocks.

3. The ideas are quantitatively rigorous since ARMA-GARCH is a known econometric model and furthermore Granger causality tests makes me more confident of these findings.

4. The flexibility of this model is also excellent as this approach allows for additional predictors and can easily be adapted for other industries or sectors. Hence, the potential for wide application is prominent.

Although I would've loved to see GARCH-MIDAS being used here, where mixed data sampling makes the model more robust. Here, MIDAS regression involves using different sampling frequencies in the independent and dependent variables.

The new variant (JN1) apparently was identified in 56k people in SGP in a week. That's huge for Singapore.

'Because of its transmissibility, JN.1 can become the dominating strain of circulating COVID virus unless proactive preventive measures are not followed which are - frequent hand sanitization, usage of Triply mask, and social distancing,' said Dr Tushar Tayal, lead consultant, internal medicine, at CK Birla Hospital in Gurugram.

Welcome to Product Managers's Private Community

Hey everyone, happy to answer any questions around Data Science/ML/AI and making a career within it

A brief about me, I work currently as a Sr. ML Engineer at an Indian unicorn startup 
I graduated 5+ years ago and have since worked as a Data Scientist / ML Engineer at an ecommerce company and social media company. My designations have changed based on the industry requirements and work too changed based on that.

Would love to take questions on what it means to be an ML Engineer, my early learnings from a career in data science, and thoughts on AI.

Look forward to all questions :)

Whenever I read foreign media outlets, India is the new Asian Tiger that will outpace most emerging economies in growth. But Indian media and Indian people act like India is the worst place to be.

The dichotomy is extremely confusing. Why is it that foreign media coverage on our economy is more favourable than our own hopes and aspirations from this country?

PS: I am really big on Indian Exceptionalism, the belief that India's economic development and trajectory are unique or exceptional compared to other nations, driven by our large and diverse population, thriving middle class, our entrepreneurial spirit, and the emphasis on technology and innovation.

Why do Indians hate India?

Am i wrong if i check with Support or Customer success team if there are any defects due to which i see a decline in user activity in my SAAS tool since last 3 months.

I was asked this question in an interview that what would be your first step if you need to figure out why there is a decline in user activity since last 3 months.

Question

Software Engineer

I decided to look into some old projects of mine and came up with some interpolation techniques I was exploring for a geo-spatial experiment I was doing early on in my career.

So, essentially I was exploring how do I map out the AQI data collected from various points in Delhi. I wanted to interpolate data between the collected locations. So, I used an approach which used Kriging and allowed me to calculate points in between.

X and Y axis are geo-loc coordinates scaled down by MinMaxScaling.
Z axis(height) is the value collected at that point scaled for plotting.

As you can see, the blue points are the data we collected and green points were the interpolated points.

When we compared this to Weather.com data, we realized that we were within 2-3% of the measured values, which was actually insane.

The inspiration was that, I was scrolling Grapevine and saw someone use Quantum Computers to implement some algorithm. Kinda inspired me to share this hahaha.

I also developed Covid Tracker, a web app based on Covid-19 API to give real-time information on Covid-19 cases across the world 190
countries, India, and across each state of India(states+UT), a dashboard of cases(Confirmed and recovered), deaths, and active cases.

Welcome to Personal Finance's Private Community

I’ll go first, getting that old PSP, the one which had WiFi in built. Or maybe PlayStation 2 which was like 5k-6k back then.

Now, I could get a PS5 or buy games to play on my PC, but the feeling is lost. Just like my childhood.

I guess I lived a part of my childhood today. Went on a walk and had a Cornetto IceCream, which back then I didn’t have the money for and had to buy an Orange/Cola IceCream. Then, I walked around my society.

Saw a few kids playing football and instantly teleported back to when I was a kid.

Now that child is gone and the dream has too. 
But still, it feels good remembering that 5 year old me would be proud of adult me, and that’s what truly matters. 🥰
