Minimax Estimation of Distances on a Surface and Minimax Manifold Learning in the Isometric-to-Convex Setting

arXiv.org Machine Learning

The estimation of shortest paths and intrinsic distances on surfaces is a fundamental problem in computational geometry with wide-ranging applications. In motion planning, shortest paths represent resource-efficient sequences of actions to be undertaken by the agent in some given configuration space [57, 56]. In addition to the clear applications to robot locomotion and manipulation, this framework has bore fruit in the field of biology wherein proteins and folding networks are of great interest [2, 76]. In cluster analysis, geodesic distances have found use as a similarity metric to create partitions that respect the underlying geometry [51, 65, 58]. In manifold learning, the Isometric Feature Mapping (Isomap) algorithm crucially depends on the approximation of geodesic distances on the underlying surface [75], and so does another important algorithm, Maximum Variance Unfolding (MVU) [79] although in disguise [64, 12]. This is closely related to the estimation of distances for the purpose of embedding a (weighted) graph (aka multidimensional scaling with missing distances), with one of the first methods suggested for that purpose being that of using the graph distances [55, 71, 70, 62].


Energy-Based Models for Continual Learning

arXiv.org Machine Learning

We motivate Energy-Based Models (EBMs) as a promising model class for continual learning problems. Instead of tackling continual learning via the use of external memory, growing models, or regularization, EBMs have a natural way to support a dynamically-growing number of tasks or classes that causes less interference with previously learned information. We find that EBMs outperform the baseline methods by a large margin on several continual learning benchmarks. We also show that EBMs are adaptable to a more general continual learning setting where the data distribution changes without the notion of explicitly delineated tasks. These observations point towards EBMs as a class of models naturally inclined towards the continual learning regime.


AI and Jobs

#artificialintelligence

As artificial intelligence (AI) takes hold, the organizations that gain a competitive edge will be those that become more human. As artificial intelligence (AI) takes hold, the organizations that gain a competitive edge will be those that become more human. In a future teeming with robots and artificial intelligence, humans seem to be on the verge of being crowded out. But in reality, the opposite is true. To be successful, organizations need to become more human than ever.


Artificial Intelligence Course

#artificialintelligence

The short answer to What is Artificial Intelligence is that it depends on who you ask. A layman with a fleeting understanding of technology would link it to robots. They'd say Artificial Intelligence is a terminator like-figure that can act and think on its own. An AI researcher would say that it's a set of algorithms that can produce results without having to be explicitly instructed to do so. And they would all be right. AI courses at Great Learning provide you with an overview of the current implementation scenario in various industries. With an in-depth introduction to artificial intelligence, you can easily master the basics for a better future in the course.


3 Questions: Christine Walley on the evolving perception of robots in the US

#artificialintelligence

Christine J. Walley, professor of anthropology at MIT and member of the MIT Task Force on the Work of the Future, explores how robots have often been a symbol for anxiety about artificial intelligence and automation. Walley provides a unique perspective in the recent research brief "Robots as Symbols and Anxiety Over Work Loss." She highlights the historical context of technology and job displacement and illustrates examples of how other countries approach policies regarding robots, skills, and learning. Here, Walley provides an overview of the brief. Q: How are robots seen as a symbol when we think about the changing nature of work in the United States?


Key skills to Transition into Artificial Intelligence in 2020

#artificialintelligence

Artificial Intelligence and Machine Learning are the two trending technologies managing the current market place. These two can change how organizations work and people interact with one another to perform complex tasks. However, the issues that AI solves are difficult and to work in the AI industry you will require a solid and focused set of skills. Before we go to realize the precise skills needed to progress into AI. Let's see how businesses are receiving this innovation to perform the different assignments in a better and simple way. Let's have a look at the Adoption of this technology in the industries Things considered, as the tide of AI and ML keeps on creating.

An analysis of models on facial emotion detection

#artificialintelligence

Facial emotion detection is a common issue focused on in the field of cognitive science. An attempt to understand what exactly we as humans see in each other that gives us insight into other emotions is a challenge we can approach from an artificial intelligence side. While I don't have enough experience in psychology or even artificial intelligence to determine these factors, we can always start off by building a model to determine at least the start of this question. Fer2013 is a dataset with pictures of individuals labeled with the emotions of anger, happiness, surprise, disgust, and sadness. When testing humans on the dataset to correctly identify the facial expression of a set of pictures within the set, the accuracy is 65%.
