Artificial intelligence and machine learning exist on the back of a lot of hard work from humans. Alongside the scientists, there are thousands of low-paid workers whose job it is to classify and label data - the lifeblood of such systems. But increasingly there are questions about whether these so-called ghost workers are being exploited. As we train the machines to become more human, are we actually making the humans work more like machines? And what role do these workers play in shaping the AI systems that are increasingly controlling every aspect of our lives?

Can deep learning solve multiple tasks simultaneously, even when they are unrelated and very different? We investigate how the representations of the underlying tasks affect the ability of a single neural network to learn them jointly. We present theoretical and empirical findings that a single neural network is capable of simultaneously learning multiple tasks from a combined data set, for a variety of methods for representing tasks--for example, when the distinct tasks are encoded by well-separated clusters or decision trees over certain task-code attributes. More concretely, we present a novel analysis that shows that families of simple programming-like constructs for the codes encoding the tasks are learnable by two-layer neural networks with standard training. We study more generally how the complexity of learning such combined tasks grows with the complexity of the task codes; we find that combining many tasks may incur a sample complexity penalty, even though the individual tasks are easy to learn. We provide empirical support for the usefulness of the learning bounds by training networks on clusters, decision trees, and SQL-style aggregation. Standard practice in machine learning has long been to only address carefully circumscribed, often very related tasks. For example, we might train a single classifier to label an image as containing objects from a certain predefined set, or to label the words of a sentence with their semantic roles. Indeed, when working with relatively simple classes of functions like linear classifiers, it would be unreasonable to expect to train a classifier that handles more than such a carefully scoped task (or related tasks in standard multitask learning). As techniques for learning with relatively rich classes such as neural networks have been developed, it is natural to ask whether or not such scoping of tasks is inherently necessary. Indeed, many recent works (see Section 1.2) have proposed eschewing this careful scoping of tasks, and instead training a single, "monolithic" function spanning many tasks. Large, deep neural networks can, in principle, represent multiple classifiers in such a monolithic learned function (Hornik, 1991), giving rise to the field of multitask learning. This combined function might be learned by combining all of the training data for all of the tasks into one large batch-see Section 1.2 for some examples. Taken to an extreme, we could consider seeking to learn a universal circuit--that is, a circuit that interprets arbitrary programs in a programming language which can encode various tasks. But, the ability to represent such a monolithic combined function does not necessarily entail that such a function can be efficiently learned by existing methods.

Competitive board games have provided a rich and diverse testbed for artificial intelligence. This paper contends that collaborative board games pose a different challenge to artificial intelligence as it must balance short-term risk mitigation with long-term winning strategies. Collaborative board games task all players to coordinate their different powers or pool their resources to overcome an escalating challenge posed by the board and a stochastic ruleset. This paper focuses on the exemplary collaborative board game Pandemic and presents a rolling horizon evolutionary algorithm designed specifically for this game. The complex way in which the Pandemic game state changes in a stochastic but predictable way required a number of specially designed forward models, macro-action representations for decision-making, and repair functions for the genetic operations of the evolutionary algorithm. Variants of the algorithm which explore optimistic versus pessimistic game state evaluations, different mutation rates and event horizons are compared against a baseline hierarchical policy agent. Results show that an evolutionary approach via short-horizon rollouts can better account for the future dangers that the board may introduce, and guard against them. Results highlight the types of challenges that collaborative board games pose to artificial intelligence, especially for handling multi-player collaboration interactions.

The graph represents a network of 4,752 Twitter users whose tweets in the requested range contained "#VR", or who were replied to or mentioned in those tweets. The network was obtained from the NodeXL Graph Server on Tuesday, 23 March 2021 at 17:54 UTC. The requested start date was Tuesday, 23 March 2021 at 00:01 UTC and the maximum number of days (going backward) was 14. The maximum number of tweets collected was 7,500. The tweets in the network were tweeted over the 1-day, 10-hour, 57-minute period from Sunday, 21 March 2021 at 13:01 UTC to Monday, 22 March 2021 at 23:59 UTC.

Freeport-McMoRan Inc – often shorthanded as Freeport – closed down 1.83% on Thursday to $31.61 per share, dipping harder than the broader markets. The day's end marked a staggering 27 million trades for the mining company, despite continuing a recent pattern of falling stock prices as seen against the 10-day price average of $35.22. However, stock prices are still up almost 16.5% for the year. Currently, the company is trading with a forward 12-month P/E of 12.65. Freeport-McMoRan is a leading international mining company with headquarters in Phoenix, Arizona.

Network data has attracted tremendous attention in recent years, and most conventional networks focus on pairwise interactions between two vertices. However, real-life network data may display more complex structures, and multi-way interactions among vertices arise naturally. In this article, we propose a novel method for detecting community structure in general hypergraph networks, uniform or non-uniform. The proposed method introduces a null vertex to augment a non-uniform hypergraph into a uniform multi-hypergraph, and then embeds the multi-hypergraph in a low-dimensional vector space such that vertices within the same community are close to each other. The resultant optimization task can be efficiently tackled by an alternative updating scheme. The asymptotic consistencies of the proposed method are established in terms of both community detection and hypergraph estimation, which are also supported by numerical experiments on some synthetic and real-life hypergraph networks.

Millenials or the GenYs and the GenZs (1980s to the present) may no longer have an inkling about the dawn milkman on horse/water buffalo carriages/carts or motorised milk floats. Those from or who have been in the Philippines may no longer connect with the provincial folk travelling around neighbourhoods and even as far as cities selling nipa/bamboo day-to-day furniture, decor and ware on board "carabao/cow-powered" covered rickety wagons. These were well-remembered on Wednesday afternoon when Dubai-based fashion entrepreneur Fareda Ali spoke with Gulf Today about the "EOO8" concept-cum-invention among other Artificial Intelligence (AI)-driven creations introduced to the media and fashion aficionadoes at the D3 or Dubai Design District. Ali is a UAE-born Sudanese-Canadian fascinated since childhood by the feel, silhouette, and sight of all fabrics, colours and designs elegantly to outlandishly laced. The fascination and passion led her to earn a degree in Fashion Design and Marketing from the Esmod Institute in Dubai two years back.

Automatic multiple-choice question generation (MCQG) is a useful yet challenging task in Natural Language Processing (NLP). It is the task of automatic generation of correct and relevant questions from textual data. Despite its usefulness, manually creating sizeable, meaningful and relevant questions is a time-consuming and challenging task for teachers. In this paper, we present an NLP-based system for automatic MCQG for Computer-Based Testing Examination (CBTE).We used NLP technique to extract keywords that are important words in a given lesson material. To validate that the system is not perverse, five lesson materials were used to check the effectiveness and efficiency of the system. The manually extracted keywords by the teacher were compared to the auto-generated keywords and the result shows that the system was capable of extracting keywords from lesson materials in setting examinable questions. This outcome is presented in a user-friendly interface for easy accessibility.
