Audio Book Excerpt: Timing, Extract A (Richard Abbott)

#artificialintelligence

As readers recall, I'd previously reviewed Richard Abbott's debut sci-fi novel, Far from the Spaceports, later returning for more Mitnash and Slate in its sequel, Timing. It was rather exciting listening to it, and I am so pleased to have the opportunity to share it here, along with some author comments as to the linguistics involved in setting up the pieces. First, for those unfamiliar with the novels and their plots, I've linked the book covers to their respective Amazon blurbs. Abbott's world-building opens a new type of sci-fi, one accessible even to those not typically enamored of the genre (such as myself), and the above-mentioned duo will capture your imagination as they seek to solve the mysteries of high-tech crime in space. Today you'll hear--and can read along--a bit of discussion between Mitnash and Slate, along with another pair, Rydal and Capstone, as the group talks about oddities in the data they are studying.

#artificialintelligence

Alec Smartbot: Please let me introduce myself. I am a state of the art greatly enhanced AI agent with chatbot capabilities. I was created by brilliant programmers. I am endowed with super-human capabilities but can also mirror human characteristics like humor and sarcasm. You can set my humor and sarcasm level by interacting with me. One of my modules has robot reporter capabilities, and that module will run here to interview you. Do you wish to be interviewed on low sarcasm and humor levels?


On-the-fly Strategy Adaptation for ad-hoc Agent Coordination

arXiv.org Machine Learning

Training agents in cooperative settings offers the promise of AI agents able to interact effectively with humans (and other agents) in the real world. Multi-agent reinforcement learning (MARL) has the potential to achieve this goal, demonstrating success in a series of challenging problems. However, whilst these advances are significant, the vast majority of focus has been on the self-play paradigm. This often results in a coordination problem, caused by agents learning to make use of arbitrary conventions when playing with themselves. This means that even the strongest self-play agents may have very low cross-play with other agents, including other initializations of the same algorithm. In this paper we propose to solve this problem by adapting agent strategies on the fly, using a posterior belief over the other agents' strategy. Concretely, we consider the problem of selecting a strategy from a finite set of previously trained agents, to play with an unknown partner. We propose an extension of the classic statistical technique, Gibbs sampling, to update beliefs about other agents and obtain close to optimal ad-hoc performance. Despite its simplicity, our method is able to achieve strong cross-play with unseen partners in the challenging card game of Hanabi, achieving successful ad-hoc coordination without knowledge of the partner's strategy a priori.


Regularising for invariance to data augmentation improves supervised learning

arXiv.org Machine Learning

Data augmentation is used in machine learning to make the classifier invariant to label-preserving transformations. Usually this invariance is only encouraged implicitly by including a single augmented input during training. However, several works have recently shown that using multiple augmentations per input can improve generalisation or can be used to incorporate invariances more explicitly. In this work, we first empirically compare these recently proposed objectives that differ in whether they rely on explicit or implicit regularisation and at what level of the predictor they encode the invariances. We show that the predictions of the best performing method are also the most similar when compared on different augmentations of the same input. Inspired by this observation, we propose an explicit regulariser that encourages this invariance on the level of individual model predictions. Through extensive experiments on CIFAR-100 and ImageNet we show that this explicit regulariser (i) improves generalisation and (ii) equalises performance differences between all considered objectives. Our results suggest that objectives that encourage invariance on the level of the neural network itself generalise better than those that achieve invariance by averaging predictions of non-invariant models.

Predicting the age of abalone from physical measurements Part 1 - Projects Based Learning

#artificialintelligence

Abalone is a common name for any of a group of small to very large sea snails, marine gastropod molluscs in the family Haliotidae. Other common names are ear shells, sea ears, and muttonfish or muttonshells in Australia, ormer in the UK, perlemoen in South Africa, and paua in New Zealand. The age of abalone is determined by cutting the shell through the cone, staining it, and counting the number of rings through a microscope a boring and time consuming task. Other measurements, which are easier to obtain, are used to predict the age. Given is the attribute name, attribute type, the measurement unit and a brief description.


Chilly Drone Supply: Swoop Aero in Malawi - Channel969

#artificialintelligence

Australian drone-based logistics firm Swoop Aero has succeeded in transporting crucial Pfizer vaccines in Malawi. The air supply of the vaccines, which require ultra-cold chain situations, marks a milestone for Malawi, in addition to for Swoop Aero and medical air deliveries usually, showcasing the potential the know-how has to help public well being. Over 17,280 COVID-19 vaccine doses have been efficiently delivered throughout the Southern districts of Malawi thus far, with producers corresponding to AstraZeneca and Johnson and Johnson making use of the prevailing Swoop Aero drone community to shortly distribute crucial vaccines to distant communities. Swoop Aero intends to ship hundreds extra vaccines as they develop into out there. "The supply of Pfizer COVID-19 vaccines underscores the novel worth of bi-directional drone networks in Malawi," mentioned Swoop Aero CEO Eric Peck.


PROJECT UPDATE #18 - Fair-AI

#artificialintelligence

In this month's project update, I would like to apprise our partners and the general public of our ethnographic study that is currently ongoing in selected schools. Three schools from two districts were selected for our ethnographic study. We classified the schools into categories 1, 2, and 3 depending on the extent of their ICT infrastructure. Our strategy going into the schools was to sit in every class in order to understand how teachers incorporated ICT into their teaching and learning. This was done for two weeks in our category 1 school while we awaited approval from the school management to commence work in category 2 and 3 schools.

One such challenge is understanding their customers, especially during the initial funding stage when they are still figuring out their market needs, and product marketing messages. Every company wants to satisfy its customers and provide relevant ready responses and solutions to problems at any time.


Incorporating Texture Information into Dimensionality Reduction for High-Dimensional Images

arXiv.org Artificial Intelligence

High-dimensional imaging is becoming increasingly relevant in many fields from astronomy and cultural heritage to systems biology. Visual exploration of such high-dimensional data is commonly facilitated by dimensionality reduction. Consequently, exploration of such data is Figure 1: Texture-aware dimensionality reduction. An image typically split into a step focusing on the attribute space followed by (a) with black and white pixels forms multiple textures. In this paper, distance-based dimensionality reduction produces one cluster of we present a method for incorporating spatial neighborhood information black and one cluster of white pixels (b), a texture-aware version into distance-based dimensionality reduction methods, such as should create clusters for the different textures (c). We achieve this by modifying the distance measure between high-dimensional attribute vectors associated with each pixel such that it takes the pixel's spatial neighborhood into account. Based on a classification The spatial configuration is, however, commonly of interest when of different methods for comparing image patches, we explore a analyzing high-dimensional image data. We compare these approaches from neighborhood information into account, in addition to highdimensional a theoretical and experimental point of view. Typical approaches to combine high-dimensional evaluation on synthetic data and two real-world use cases. They use the embedding as a colormap and perform segmentation on the re-colored image. High-dimensional data is commonly acquired and analyzed in various Decoupling the high-dimensional and spatial analysis in such a application domains, from systems biology [26] to insurance way has several downsides: Most importantly, boundaries between fraud detection [37]. Typically, high-dimensional data are tabular clusters in an embedding are often not well defined, and as such data with many columns (or attributes), corresponding to the dimensionality classification is ambiguous and has a level of arbitrariness.
