Abstract: A system for performing an assessment of the robustness and resilience of an examined original ML model against model extraction attacks includes a computerized device having at least one processor, which is adapted to: train multiple candidate models MC with the external dataset D for each of the specified candidate learning algorithms a in Alg, where each candidate substitute model is trained on a subset of D corresponding to the evaluated ith query limit of the query budget constraint Q; evaluate the performance of each substitute model MC according to different evaluation methods ?Evaluation; and calculate the robustness of each substitute model, where smaller difference or high agreement/similarity rate between the performance of the original model and the substitute model indicates that the original and substitute models are similar to each other.

Abstract: A system for testing Machine Learning (ML) and deep learning models for robustness, and durability against adversarial bias and privacy attacks, comprising a Project Repository for storing metadata of ongoing projects each of which having a defined project policy, and created ML models and data sources being associated with the ongoing projects; a Secure Data Repository, for storing training and testing datasets and models used in each project for evaluating the robustness of the each project; a Data/Model Profiler for creating a profile, based on the settings and configurations of the datasets and the models; a Test Recommendation Engine for recommending the relevant and most indicative attacks/tests for each examined model and for creating indicative and effective test suites; a Test/Attack Ontology module for storing all attacks/tests with their metadata and mapping the attacks/tests to their corresponding settings and configurations; an Attack Repository for storing the implemented tests/attacks.

Abstract: Apparatus and methods are provided for eliminating axial porosity accompanied by impurity segregation arising at bulk crystallization of the axial zone of the liquid core of a continuous ingot.

Abstract: An inductor for the excitation of polyharmonic rotating magnetic fields (RMF) for controlling the crystalline structure of continuous ingots and castings in metallurgy and other foundry applications. The inductor design makes it possible to use standard sources of sinusoidal currents for generating polyharmonic RMF, and significantly increase cos ? of the inductor.

Abstract: A system and method for producing anharmonic multi-phase currents wherein the harmonic component of an inverter is filtered and superimposed with a series of control pulses to create a control signal. The control signal is fed back to the inverter, causing the inverter to produce anharmonic multi-phase currents.

Abstract: Apparatus and methods are provided for eliminating axial porosity accompanied by impurity segregation arising at bulk crystallization of the axial zone of the liquid core of a continuous ingot.

Abstract: A method is provided for suppressing a vortex arising in a tundish or ladle at the lowering of the free surface of the melt below a critical level using a rotating magnetic field excited in the melt above an outflow pipe by an RMF inductor of a special design.

Abstract: The invention is an improved and environmentally-friendly animal bedding material, particularly useful as horse bedding. The bedding of the invention is generally non-irritating, substantially dust free flax shives which have an inner core and outer surface with sufficient inner core being exposed to make the bedding absorbent.
