Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed for managing training for models. An example apparatus includes a processor circuitry to at least obtain a request to train or retrain a model, respond to the request by preventing the train or retraining, calculate at least one performance metric, and compare performance metric corresponding to current model execution to at least one threshold performance metric.

Abstract: The present invention relates generally to the field of piñata stands, and particularly to a foldable piñata stand and methods which allow for easy quick set up of the piñata assembly and quick and easy folding and transporting of the piñata stand. The present invention is particularly adaptable for setting up a game of piñata in locations where there are no trees or the trees do not have branches of appropriate height for the piñata. The present invention eliminates the need for finding branched trees or other tall structures for hanging the piñata.

Abstract: A system for applying hair extensions to natural hair growing on the scalp of an individual comprises cylindrical tubes, a threading tool and a crimping tool. The cylindrical tube has a second end opening larger than a first end opening. The threading tool is used to feed scalp hair through the cylindrical tube. The hair extension is then inserted into the second end of the tube and the tube is crushed flat trapping the threaded scalp hair and hair extension within the crushed structure.

Abstract: A system for applying hair extensions to natural hair growing on the scalp of an individual comprises flared cylindrical tubes, a threading hook and a crimping tool. The threading tool is used to feed scalp hair through the flared tube. The hair extension is then inserted into the flared end or the tube and the tube is crushed flat trapping the threaded scalp hair and hair extension within the crushed structure. The removal of the hair extension is facilitated by use of a removal tool designed to open the crimped flared tube.
