After starting chess, my rating immediately settled in the 800s. This is considered low novice territory; 2889 is the highest all-time rating, held by Magnus Carlsen. I wasn’t getting better regardless of the time spent.
So, you’re a PM and there’s been a lot of talk about how AI is revolutionizing the industry, how your company is data-driven, or how your product has a deep analytics focus. But what exactly does that mean? Without understanding how data-powered applications work, your PRD’s will be long on buzzwords and short on substance. We can talk ourselves in circles about the value of analytics, but without understanding how to productize machine learning, we’ll never actually ship.
This article will walk you through the five steps of building and deploying machine learning models, using time-series anomaly detection to demonstrate a real-world example. …
Designing cities for the future of mobility
The adoption of cars during the 20th Century dramatically improved standard of living while driving massive social changes and more subtle requirements in urban planning. Over time city planners developed precise zoning requirements from the Institute of Transportation Engineers’ (ITE) Parking Generation Manual, which have been shown to be arbitrary and not data-driven. Even in low-income housing projects where many residents don’t own cars, zoning codes require vast lots to house these non-existing vehicles. These regulations were well-intentioned but often resulted in bizarre outcomes.
Form follows parking: parking regulations enforce an arbitrary abundance of spots. Many downtowns devote 50 to 60% of their real estate to vehicles: with typically 30% of the surface for roads and 20% for off-street parking. …
Policies that reduce further emissions and remediate land provide cost-effective, long-term solutions.
Ever since spending my summers living in the countryside of 峭崎鎮 (a village in the Jiangsu province) teaching English, I’ve been extremely interested in rural pollution in China. I’ve written for many years on the issue and wanted to use principles from system dynamics to model the spread of pollution in order to simulate the impact of various pollution tax policies on the land.
Through tax benefits and lax environmental standards, local governments incentivize the building of factories to grow their economy. The resulting factory pollution contaminates land via wastewater. Polluted land becomes infertile and uninhabitable, killing residents and the local farming industry. As current research suggests that more than 70% of China’s soil could have problems, China nears the “red line” of 120 million arable hectares needed to sustain the population. Therefore, rural pollution poses a threat to the long-term viability of the country. …
