学习 优化 数值特性 Learn to Optimize 机器学习
2023/5/12
数学优化是一个基础领域，研究如何在给定的一组约束条件下找到函数的最小值。面对着非凸、组合、高纬度、数值问题等挑战下，在过去的 80 年中运筹专家、经济学家、控制论专家和数学家通过对数学和数值特性的研究，发现了一系列有效的方法。然而，一种被称为Learn to Optimize新范式可以利用机器学习来加速发现新的优化方法。本报告将介绍两个新工作。一个是关于图神经网络用于线性规划和混合整数规划求解的理...

Researchers learn how the cancer-causing stomach bacterium Helicobacter maintains its shape（图）
Researchers cancer-causing stomach bacterium Helicobacter
2020/2/20
NSF-funded scientists reporting in the journal eLife have revealed that they are closer to understanding a risk factor for stomach cancer: how the bacterium Helicobacter pylori...
NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its res...
Batlab studies echolocation to learn how animals "see" with sound（图）
Batlab echolocation animals see sound
2017/11/23
Neuroscientist Cindy Moss is investigating how animals use sensory information to guide their behavior. Her team at Johns Hopkins University's "Batlab" is currently focused on bat echolocation -- high...
NSF/NASA/NCAR press conference:What will scientists learn from the August 21 total solar eclipse?
NSF NASA NCAR press conference scientists learn the August 21 total solar eclipse
2017/7/24
The total solar eclipse next month is the first to cross the U.S. from coast to coast in nearly a century, giving scientists a unique opportunity to observe the sun's corona with an array of technolog...
What we can learn about global flu evolution from individual infections
we can learn global flu evolution individual infections
2017/7/24
A new study has found that flu evolution within some individuals can hint at the virus’s eventual evolutionary course worldwide.Samples taken more than 10 years ago from people with unusually long flu...
Seventh-graders learn astrophysics through mixed-reality computer simulation
Seventh-graders astrophysics mixed-reality computer simulation
2016/4/13
Had the “learn’d astronomer’s” charts and theorems inspired the 19th-century writer Walt Whitman as much as strolling under the nighttime sky, Whitman might have become an astrophysicist instead of a ...
This note focuses on the ground motion recorded during the recent moderate earthquakes that occurred in the central part of northern Italy (Panel 1), a region that is characterized by low seismicity. ...
Which graphical models are difficult to learn?
Ising model binary markov random field markov random
2015/8/21
We consider the problem of learning the structure of Ising models (pairwise binary Markov random fields) from i.i.d. samples. While several methods have been proposed to accomplish this task, their re...
High ability learning and brain processes : how neuroscience can help us understand how gifted and talented students learn and the implications for teaching
brain processes neuroscience
2015/6/1
Gifted and talented learners understand, think and know in ways that differ qualitatively from how regular learners perform these activities. Recent research that has examined the neuropsychological p...
Using Dark Matter Haloes to Learn about Cosmic Acceleration: A New Proposal for a Universal Mass Function
Dark Matter Haloes Cosmic Acceleration
2011/1/11
Structure formation provides a strong test of any cosmic acceleration model because a successful dark energy model must not inhibit {\black or overpredict} the development of observed large-scale stru...
GOME-2 observations of oxygenated VOCs: what can we learn from the ratio glyoxal to formaldehyde on a global scale?
GOME-2 oxygenated VOCs the ratio glyoxal a global scale
2010/11/3
Collocated data sets of glyoxal (CHO.CHO) and formaldehyde (HCHO) were retrieved for the first time from measurements of the Global Ozone Monitoring Experiment-2 (GOME-2) during the first two years of...
Astrophysical Jets : what can we learn from Solar Ejections?
Sun coronal mass ejections Galaxies jets Magnetic reconnection
2010/11/11
Ejections from the Sun can be observed with a higher resolution than in any other astrophysical object: can we build up on solar results and apply them to astrophysical objects? Aim of this work is to...
Estuarine oxygen dynamics: What can we learn about hypoxia from long-time records in the Delaware Estuary?
Estuarine oxygen dynamics Delaware Estuary
2014/4/16
Hypoxia and anoxia occurred in the upper Delaware Estuary throughout much of the 20th century and
diminished over the past several decades. I reviewed 30 yr of data from my laboratory’s research effo...
