Factors to Consider When Building a Small Scale Robotics Lab

#artificialintelligence

A robotics lab is a hub of various technologies working together under the expertise of the human mind under a single roof. While anyone can make their own robotics lab, housing numerous robots in a room does not qualify as a robotics lab. In layman's terms to constitute an ideal robotics lab, one needs a perfect balance of hardware, software, design tools, and human resource. However, many people fail to understand this simple idea and, as a result, are often stressed when planning to build one. In short, the problem areas are lack of information resources and time to understand them.

Speeches of US politicians 'have the reading age of a 13-year-old'

Daily Mail - Science & tech

Congressional speeches made by US politicians have become simpler since the 1970s and only require the reading age of a 13-year-old to be followed, study found. Computer scientists from Kansas State University analysed two million congressional speeches from Republican and Democrat politicians made between 1873 and 2010. Text analysis algorithms were used to examine how congressional speeches changed in terms of complexity, emotion and divisiveness over 138 years. More recent speeches use a smaller vocabulary, simpler language and talk about'the other party' more than speeches made even a decade ago, the authors found. Researchers put the drop in the reading level down to the rise of broadcast media in congress that started in the mid-1970s - with politicians'playing to the camera'.


Distance learning: 4 smart tech solutions for keeping kids on track

PCWorld

Raise your hand if this sounds familiar: It's five minutes until your third-grader's distance learning class, but just as you're about to make sure she's dialed into her Zoom call, something comes up with your own work. Thirty minutes later, you finally head over to your daughter's room, only to find her sprawled on the floor watching her iPad. Meanwhile, her Chromebook--the one she uses for Zoom calls--is securely shut. Yes, she just missed another class, and you (bad parent!) let it happen. Keeping your kids on track while juggling your own obligations has to be one of the biggest challenges of distance learning, remote learning, virtual learning or whatever you want to call it.


Online Deep Learning (ODL) and Hedge Back-propagation

#artificialintelligence

As the main concept of deep neural networks is to train through back-propagation in a batch setting, the data is required to be available in an offline setting. As a consequence, the scheme is irrelevant for many practical situations, in which the data arrives in sequence and cannot be stored. ODL is very challenging as it cannot use back-propagation. Two years ago, Sahoo et al (2018) addressed the gap between online learning and deep learning, where they claimed that "without the power of depth, it would be difficult to learn complex patterns". They presented a novel framework for ODL (to be reviewed later).


IBM offers teachers and students new learning resources focused on AI - Good Tech IBM

#artificialintelligence

The United Nations today established International Youth Day over twenty years ago, recognizing that young people can be a positive force for our collective development when provided with the knowledge and opportunities they need to thrive. Today, there are 1.2 billion young people aged 15 to 24 years, accounting for 16 percent of the global population. And by 2030--the target date for the Sustainable Development Goals (SDGs) that make up the U.N. 2030 Agenda--the number of youth is projected to have grown by 7 percent, to nearly 1.3 billion. Findings from a new study by IBM and Morning Consult[1] reveal this demographic knows technology will alter their future. Young people recognize skills like AI and data science will change their careers, and yet they feel unprepared to work with them.


What to study: Artificial intelligence

#artificialintelligence

Artificial intelligence (AI) has been touted as a gamechanger in the future job market. In the UK alone, one in three jobs is likely to be automated or changed as a result of AI. This has created a great demand for data experts across every industry that employs the use of computer systems. According to LinkedIn's 2020 Emerging Jobs Report, the demand for AI experts has grown 74% annually over the past five years. It is now the number one emerging job.

A new role for circuit expansion for learning in neural networks

arXiv.org Machine Learning

Many sensory pathways in the brain rely on sparsely active populations of neurons downstream from the input stimuli. The biological reason for the occurrence of expanded structure in the brain is unclear, but may be because expansion can increase the expressive power of a neural network. In this work, we show that expanding a neural network can improve its generalization performance even in cases in which the expanded structure is pruned after the learning period. To study this setting we use a teacher-student framework where a perceptron teacher network generates labels which are corrupted with small amounts of noise. We then train a student network that is structurally matched to the teacher and can achieve optimal accuracy if given the teacher's synaptic weights. We find that sparse expansion of the input of a student perceptron network both increases its capacity and improves the generalization performance of the network when learning a noisy rule from a teacher perceptron when these expansions are pruned after learning. We find similar behavior when the expanded units are stochastic and uncorrelated with the input and analyze this network in the mean field limit. We show by solving the mean field equations that the generalization error of the stochastic expanded student network continues to drop as the size of the network increases. The improvement in generalization performance occurs despite the increased complexity of the student network relative to the teacher it is trying to learn. We show that this effect is closely related to the addition of slack variables in artificial neural networks and suggest possible implications for artificial and biological neural networks.


Robust Mean Estimation on Highly Incomplete Data with Arbitrary Outliers

arXiv.org Machine Learning

We study the problem of robustly estimating the mean of a $d$-dimensional distribution given $N$ examples, where $\varepsilon N$ examples may be arbitrarily corrupted and most coordinates of every example may be missing. Assuming each coordinate appears in a constant factor more than $\varepsilon N$ examples, we show algorithms that estimate the mean of the distribution with information-theoretically optimal dimension-independent error guarantees in nearly-linear time $\widetilde O(Nd)$. Our results extend recent work on computationally-efficient robust estimation to a more widely applicable incomplete-data setting.
