Mythos Foundation, Mythos DAO and Mythos Token (MYTH) Launch to Democratize Web3 Gaming
The Mythos Foundation has been established to manage the day-to-day operations of the Mythos blockchain gaming ecosystem decentralized autonomous organization (DAO). With support from industry leaders in web3 gaming, the goal of the Mythos Foundation is to reduce barriers-to-entry for innovative game developers wanting to build thriving play-and-own game economies. The Mythos Foundation also aims to democratize games and allow for players and creators to participate in game value chains through the Mythos ecosystem, which is grounded in the support of multiple blockchains, unified marketplaces, decentralized financial systems and decentralized governance mechanisms. "Mythical has always been a gamer-first platform, and today's announcement signals our commitment to ensuring our community has increased ownership over their gaming experience" Mythos is also announcing the Mythos token (MYTH), an ERC-20 mainnet token with a fixed supply of 1 billion tokens, that will provide web3 game utility and facilitate ecosystem governance, giving gamers, developers, publishers, and content creators the opportunity to participate and contribute to a truly decentralized ecosystem. Mythical Games is the first to adopt MYTH as its native utility token on the Mythical Chain and will use the token on its Mythical Marketplace.
UFTR: A Unified Framework for Ticket Routing
Han, Jianglei, Li, Jing, Sun, Aixin
Corporations today face increasing demands for the timely and effective delivery of customer service. This creates the need for a robust and accurate automated solution to what is formally known as the ticket routing problem. This task is to match each unresolved service incident, or "ticket", to the right group of service experts. Existing studies divide the task into two independent subproblems - initial group assignment and inter-group transfer. However, our study addresses both subproblems jointly using an end-to-end modeling approach. We first performed a preliminary analysis of half a million archived tickets to uncover relevant features. Then, we devised the UFTR, a Unified Framework for Ticket Routing using four types of features (derived from tickets, groups, and their interactions). In our experiments, we implemented two ranking models with the UFTR. Our models outperform baselines on three routing metrics. Furthermore, a post-hoc analysis reveals that this superior performance can largely be attributed to the features that capture the associations between ticket assignment and group assignment. In short, our results demonstrate that the UFTR is a superior solution to the ticket routing problem because it takes into account previously unexploited interrelationships between the group assignment and group transfer problems.
Regression Phalanxes
Zhang, Hongyang, Welch, William J., Zamar, Ruben H.
Tomal et al. (2015) introduced the notion of "phalanxes" in the context of rare-class detection in two-class classification problems. A phalanx is a subset of features that work well for classification tasks. In this paper, we propose a different class of phalanxes for application in regression settings. We define a "Regression Phalanx" - a subset of features that work well together for prediction. We propose a novel algorithm which automatically chooses Regression Phalanxes from high-dimensional data sets using hierarchical clustering and builds a prediction model for each phalanx for further ensembling. Through extensive simulation studies and several real-life applications in various areas (including drug discovery, chemical analysis of spectra data, microarray analysis and climate projections) we show that an ensemble of Regression Phalanxes improves prediction accuracy when combined with effective prediction methods like Lasso or Random Forests.
Ensembling classification models based on phalanxes of variables with applications in drug discovery
Tomal, Jabed H., Welch, William J., Zamar, Ruben H.
Statistical detection of a rare class of objects in a two-class classification problem can pose several challenges. Because the class of interest is rare in the training data, there is relatively little information in the known class response labels for model building. At the same time the available explanatory variables are often moderately high dimensional. In the four assays of our drug-discovery application, compounds are active or not against a specific biological target, such as lung cancer tumor cells, and active compounds are rare. Several sets of chemical descriptor variables from computational chemistry are available to classify the active versus inactive class; each can have up to thousands of variables characterizing molecular structure of the compounds. The statistical challenge is to make use of the richness of the explanatory variables in the presence of scant response information. Our algorithm divides the explanatory variables into subsets adaptively and passes each subset to a base classifier. The various base classifiers are then ensembled to produce one model to rank new objects by their estimated probabilities of belonging to the rare class of interest. The essence of the algorithm is to choose the subsets such that variables in the same group work well together; we call such groups phalanxes.
