I have taken courses in mathematical statistics, high-dimensional statistics, machine learning, deep learning, and several optimization courses. Additionally, I am registered for an econometrics course next semester😱. So, like currently, it’s a stage where I have laid a strong theoretical foundation and possess a mastery of Python and R in data analysis, but my hands-on experience in tackling real-world problems is almost non-existent. After all, the datasets we used in class assignments are primarily toy examples that are cleaned, checked, and designed for specific tasks....

I’ve been a little bit overwhelmed today. So, here’s a music recommendation. SANCAN: Sonatine for Flute and Piano: I. Moderato [composer]: Pierre Sancan [artist]: Emmanuel Pahud, Eric Le Sage. [album]: Paris Jan. 20, 1998. Parlophone Records Limited. The opening 45 seconds of this piece are like a fog-draped dream. The piano strikes raindrops of notes on a misty, ethereal dreamscape, like cobblestoned street under the soft glow of a solitary streetlamp....

There’s a carnival of groceries at the heart of the town, lively, a bit chaotic, and full of fruit stands. Each one offers a variety of fruits that seem similar but are unique in their quality and price. I was looking for a specific local banana🍌, known for being budget-friendly yet deliciously sweet when ripe. I wandered from stall to stall, asking for it, but had no luck. The vendors kept steering me towards a different type of banana, claiming it was better – but it just wasn’t what I wanted....

Cracking Down on Induced Positive Reviews - Dianping’s Firm Stance.

Reflecting on my use of the app, it’s clear that it has significantly improved the classical music listening experience, making it more professional, smooth, and enjoyable. huh? another music app?...

According to Better Heath Channel Mountain climbers are at risk of developing altitude sickness (also known as mountain sickness), which may be harmful or even fatal if its onset is ignored. It is caused by gaining altitude too rapidly, which doesn’t allow the body enough time to adjust to reduced oxygen and changes in air pressure, and causes hypobaric hypoxia (a lack of oxygen reaching the tissues of the body)....

In our digitally inter-connected era, platforms like Dianpin and Yelp have become integral to our decision-making process for choosing restaurants, hotels, and entertainment. These online rating platforms are revolutionizing the demand pattern hence revenue stream of service providers. Basically, ratings platforms are to provision information. Service providers, from local bistros to boutique hotels, register themselves on these platforms. Consumers then rate these services, often accompanied by comments and photos. These ratings are the lifeblood of these platforms, determining how businesses are ranked and recommended to new users searching for, say, “nearby hotpot restaurants....

Whenever one downloads a new app on an iPhone, a system notification pops up, inquiring if one wish to permit cross-application tracking. Apple has long championed this feature, underscoring their commitment to user privacy. Apple’s marketing not only highlights Apple’s dedication to privacy but also subtly positions their products as trustworthy guardians of personal data. However, I’ve also read about (although not taking their opinions seriously cause I had been a stan of Apple by then) some critics pointing to a nuanced concern....

A classic example when the model works fine but the real market gets fucked up with misaligned incentives.
