Curtin University alliance to focus research on artificial intelligence impact
Curtin University, in Western Australia, will be working with Optus Business as they form a research group that will focus on the impact of artificial intelligence (AI) on regional telecommunications, higher education and the urban environment. According to the report made by the University, an artificial intelligence research group will be formed from the five-year alliance. The group will be embedded in the School of Electrical Engineering, Computing and Mathematical Sciences at the University, having strong links to the Curtin Institute for Computation. The excellent research, teaching and learning capabilities of the University will be synergised with the market-leading technology and infrastructure capabilities of the telco company and will be fully leveraged by the alliance of both. The research group will involve the appointment of an Optus Chair in Artificial Intelligence and three Optus Research Fellows focusing on applying artificial intelligence technologies in areas such as regional telecommunications, improving higher education student outcomes and the urban environment.
Optimal sequential treatment allocation
Kock, Anders Bredahl, Thyrsgaard, Martin
In treatment allocation problems the individuals to be treated often arrive sequentially. We study a problem in which the policy maker is not only interested in the expected cumulative welfare but is also concerned about the uncertainty/risk of the treatment outcomes. At the outset, the total number of treatment assignments to be made may even be unknown. A sequential treatment policy which attains the minimax optimal regret is proposed. We also demonstrate that the expected number of suboptimal treatments only grows slowly in the number of treatments. Finally, we study a setting where outcomes are only observed with delay.
An Improvement of Data Classification Using Random Multimodel Deep Learning (RMDL)
Heidarysafa, Mojtaba, Kowsari, Kamran, Brown, Donald E., Meimandi, Kiana Jafari, Barnes, Laura E.
The exponential growth in the number of complex datasets every year requires more enhancement in machine learning methods to provide robust and accurate data classification. Lately, deep learning approaches have achieved surpassing results in comparison to previous machine learning algorithms. However, finding the suitable structure for these models has been a challenge for researchers. This paper introduces Random Multimodel Deep Learning (RMDL): a new ensemble, deep learning approach for classification. RMDL solves the problem of finding the best deep learning structure and architecture while simultaneously improving robustness and accuracy through ensembles of deep learning architectures. In short, RMDL trains multiple randomly generated models of Deep Neural Network (DNN), Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) in parallel and combines their results to produce better result of any of those models individually. In this paper, we describe RMDL model and compare the results for image and text classification as well as face recognition. We used MNIST and CIFAR-10 datasets as ground truth datasets for image classification and WOS, Reuters, IMDB, and 20newsgroup datasets for text classification. Lastly, we used ORL dataset to compare the model performance on face recognition task.
Inspired by Nature: Autonomous Underwater Robotics
Since he was a child, Derek Paley has been captivated by how shoals of fish move fluidly as a cohesive group, almost as if a single organism. As the Willis H. Young Jr. Professor of Aerospace Engineering Education and director of the Collective Dynamics and Control Laboratory at the University of Maryland, Paley is applying his long-standing source of inspiration to the cooperative control of autonomous vehicles. Fish are particularly interesting for Paley because of their sensory system. He explains that fish have a lateral line system, which is a series of sensors located on their exterior, sometimes appearing on their side as a stripe. With their lateral line sense, fish can perceive the direction and speed of nearby water flow, as well as predators and other obstacles.
Schooling Flappy Bird: A Reinforcement Learning Tutorial
In classical programming, software instructions are explicitly made by programmers and nothing is learned from the data at all. In contrast, machine learning is a field of computer science which uses statistical methods to enable computers to learn and to extract knowledge from the data without being explicitly programmed. In this reinforcement learning tutorial, I'll show how we can use PyTorch to teach a reinforcement learning neural network how to play Flappy Bird. But first, we'll need to cover a number of building blocks. Machine learning algorithms can roughly be divided into two parts: Traditional learning algorithms and deep learning algorithms. Traditional learning algorithms usually have much fewer learnable parameters than deep learning algorithms and have much less learning capacity. Also, traditional learning algorithms are not able to do feature extraction: Artificial intelligence specialists need to figure out a good data representation which is then sent to the learning algorithm. Examples of traditional machine learning techniques include SVM, random forest, decision tree, and $k$-means, whereas the central algorithm in deep learning is the deep neural network. The input to a deep neural network can be raw images, and an artificial intelligence specialist doesn't need to find any data representation--the neural network finds the best representation during the training process. A lot of deep learning techniques have been known for a very long time, but recent advances in hardware rapidly boosted deep learning research and development.
Japan to Use Artificial Intelligence Robots in English Classes to Boost Spoken Skills - The Sentinel
Tokyo: The government of Japan is planning to introduce English-speaking Artificial Intelligence (AI) robots in classrooms to help children improve their English speaking skills, considered one of the worst in the world. The Japanese education ministry would be launching a pilot programme to test the effectiveness of the initiative in April 2019, reports Efe news. The initiative will be initially rolled out in 500 schools throughout the country with the aim of fully implementing it in two years, public broadcaster NHK reported Saturday. The programme also includes study apps and online conversation sessions with native English speakers. Japan has proposed improving English skills ahead of the surge in tourists expected during the 2020 Summer Olympics in Tokyo.
Udacity's Next Generation Of Machine Learning And Data Science Courses: An Early Review
I like to keep regular tabs on the state of data science education in America. As one of the hottest fields in the economy, I find that the quality of data science courses is a leading indicator of the state of online education innovation. So, when I see significant new develops in online education technology, I'll dedicate some time to taking the course (and, selfishly, I like to learn new data skills). One website that I've used before, Udacity, recently launched several new courses on artificial intelligence, machine learning and statistics. I've had mixed experiences with Udacity in the past.

Channel Charting: Locating Users within the Radio Environment using Channel State Information
Studer, Christoph, Medjkouh, Saïd, Gönültaş, Emre, Goldstein, Tom, Tirkkonen, Olav
Abstract--We propose channel charting (CC), a novel framework in which a multi-antenna network element learns a chart of the radio geometry in its surrounding area. The channel chart captures the local spatial geometry of the area so that points that are close in space will also be close in the channel chart and vice versa. CC works in a fully unsupervised manner, i.e., learning is only based on channel state information (CSI) that is passively collected at a single point in space, but from multiple transmit locations in the area over time. The method then extracts channel features that characterize large-scale fading properties of the wireless channel. Finally, the channel charts are generated with tools from dimensionality reduction, manifold learning, and deep neural networks. The network element performing CC may be, for example, a multi-antenna base-station in a cellular system and the charted area in the served cell. Logical relationships related to the position and movement of a transmitter, e.g., a user equipment (UE), in the cell can then be directly deduced from comparing measured radio channel characteristics to the channel chart. The unsupervised nature of CC enables a range of new applications in UE localization, network planning, user scheduling, multipoint connectivity, handover, cell search, user grouping, and other cognitive tasks that rely on CSI and UE movement relative to the base-station, without the need of information from global navigation satellite systems. UTURE wireless communication systems must sustain a massive increase in traffic volumes, number of terminals, and reliability/latency requirements [2], [3]. C. Studer, S. Medjkouh, and E.
