Why Momentum Really Works
Posted by Armando Brito Mendes | Filed under Data Science, infogramas \ dashboards, materiais ensino
Uma excelente explicação de como funciona o momentum em redes neuronais
Here’s a popular story about momentum [1, 2, 3]: gradient descent is a man walking down a hill. He follows the steepest path downwards; his progress is slow, but steady. Momentum is a heavy ball rolling down the same hill. The added inertia acts both as a smoother and an accelerator, dampening oscillations and causing us to barrel through narrow valleys, small humps and local minima.
This standard story isn’t wrong, but it fails to explain many important behaviors of momentum. In fact, momentum can be understood far more precisely if we study it on the right model.
One nice model is the convex quadratic. This model is rich enough to reproduce momentum’s local dynamics in real problems, and yet simple enough to be understood in closed form. This balance gives us powerful traction for understanding this algorithm.

How concrete, asphalt and urban heat islands add to the misery of heat waves
PUBLISHED JULY 31, 2023 15:40 AZOST
It only takes just a fraction of a second to suffer a pretty serious burn. Asphalt and concrete in direct sunlight can often reach surface temperatures as high as 82 Celsius (180 Fahrenheit) on the hottest days, said Dr. Kevin Foster, who directs the Arizona Burn Center in Phoenix.
Forecasters predict another heat wave in Phoenix this week after the U.S. National Weather Service declared the city had sweltered under high temperatures above 43°C (115°F) for 30 consecutive days in July. Across Europe, high temperature records have tumbled this summer and major heat waves in much of the world are expected to persist through August.

zenodo – open science
Posted by Armando Brito Mendes | Filed under data sets
Um excelente site com montes de dados de todos os tipos
Passionate about Open Science!
Built and developed by researchers, to ensure that everyone can join in Open Science.
The OpenAIRE project, in the vanguard of the open access and open data movements in Europe was commissioned by the EC to support their nascent Open Data policy by providing a catch-all repository for EC funded research. CERN, an OpenAIRE partner and pioneer in open source, open access and open data, provided this capability and Zenodo was launched in May 2013.
In support of its research programme CERN has developed tools for Big Data management and extended Digital Library capabilities for Open Data. Through Zenodo these Big Science tools could be effectively shared with the long-tail of research.
Open Science knows no borders!
The need for a catch-all is not restricted to one funder, or one nation, so the concept caught on, and Zenodo rapidly started welcoming research from all over the world, and from every discipline.
The digital revolution has necessitated a retooling of the scholarly processes to handle data and software, but this is proceeding at varying speeds across different communities, disciplines, and nations. To ensure no one is left behind through lack of access to the necessary tools and resources, Zenodo makes the sharing, curation and publication of data and software a reality for all researchers.
Geographic misconceptions about the location of continents

Uma estória sobre a geografia com boas animações
Misconceptions often seem to have a life of their own.
If learned early on, a foundationally incorrect view of the world can perpetuate, as students naturally build knowledge in light of a past, incorrect, understanding. Something as basic as our assumptions about the relative locations of Earth’s continents is an interesting, and actually sort of fun, example of how we can get things wrong right off the bat. Ultimately, everything is learned, but some curious geographic errors tend to persist more than others.
So what are some tantalizing locational mistakes that seemingly come pre-installed in American students’ minds that geography teachers wrestle to overcome?
So glad you asked! Here is a cherry-picked handful of examples that we’ll dive into…
- The northiness of Africa
- The northiness of Europe
- The eastiness of South America

After spiraling to new heights during the pandemic, the housing market is finally starting to cool. Data on how fast homes have sold over the past decade shows how the market took off in the summer of 2020 and began to wind back down this spring.
