Abstract: Today crowdsourcing consists of activities which may involve large numbers of individuals but there is no social aspect to the crowdsourcing activities and poor visibility of the crowdsourced results by others. Embodiments of the invention provide an online portal supporting both mobile and non-mobile users with social media and social network visibility of the crowdsourcing being undertaken/requested by others. Such crowdsourcing may also be inventivised by either the generator of the crowdsourced microactions or third parties who are independent of the generator and executer of the crowdsourced activity. Beneficially, the crowdsourcing portal leverages acquiring multimedia content or a user's geolocation in mobile environments to provide part of the completion process for a crowdsourced activity.

Abstract: The disclosed microtraining techniques improve accuracy of trained neural networks by performing iterative refinement at low learning rates using a relatively short series microtraining steps. A neural network training framework receives the trained neural network along with a second training dataset and set of hyperparameters. The neural network training framework produces a microtrained neural network by adjusting one or more weights of the trained neural network using a lower learning rate to facilitate incremental accuracy improvements without substantially altering the computational structure of the trained neural network. The microtrained neural network may be assessed for changes in accuracy and/or quality. Additional microtraining sessions may be performed on the microtrained neural network to further improve accuracy or quality.
