Abstract: A computer-implemented method for inductive learning on graphs is disclosed, wherein the graph (110) includes a plurality of entities (112), wherein relationships exist between the entities (112), and wherein the entities (112) and relationships have a name string. According to embodiments of the invention, the method comprises: (a) creating for each entity (112) of the graph (110), based on the entity's (112) name string, a related text corpus; (b) using a pretrained language model (150) to compute, from the related text corpus of an entity (112), a respective contextual entity embedding for each entity (112) of the graph (110); training a graph-based machine-learning, ML, model (210) by using, for each entity (112) of the graph (110), the computed entity embeddings; and repeating, for unseen entities, steps (a) and (b) and using the trained ML model (210) to perform inductive predictions for the unseen entities.

Abstract: The present invention provides a method of providing security for a machine learning, ML, classifier against adaptive gray-box adversarial samples. According to embodiments, the method comprises inspecting, by a detector component, input samples submitted to the ML classifier to identify input samples that appear as noisy versions of previously submitted queries and/or as highly distorted input samples; and forwarding, by the detector component, only those input samples to the ML classifier that were not identified as noisy versions of previously submitted queries or as highly distorted input samples.

Abstract: The present invention relates to a computer-implemented method of resource allocation for multiple virtualized base stations, vBSs (420), deployed in a shared radio computing platform (410), wherein the vBSs (420) share the same Radio Unit, RU (430), having a fixed number of Physical Resource Blocks, PRBs. With respect to an efficient utilization of both radio resources and available computing resources, the method comprises obtaining, by a radio controller, a set of metrics from the radio computing platform (410) for each of the vBSs (420) deployed; learning, by a learning agent (450) of the radio controller based on the obtained set of metrics, the traffic patterns and the CPU consumption of the vBSs (720) deployed; and computing, by the radio controller based on the knowledge of current CPU set configurations of the vBSs (420) and based on the learned traffic patterns and the CPU consumption of the vBSs (420), a CPU set configuration, L3 cache allocation and PRB assignment for each vBS (420) in such a way that at least one of the overall CPU overhead, the decoding time and SLA violations are minimized.

Abstract: The present invention relates to a computer-implemented method for execution of a cryptographic sortition among a group of parties (210, 220). According to an embodiment of the invention, the method comprises committing, by a first party (210) of the group, to a set of n party-specific secret keys k1,..., kn for a block cipher E; obtaining, by the first party (210) and at least a second party (220) of the group, a common input x and an index r; encrypting, by the first party (210), the input x with the r-th key kr of the committed keys k1,..., kn, thereby generating an output y1 of the block-cipher E, and publishing the output y1 together with the key kr used for encryption; and encrypting, by the second party (220), the common input x with the key kr published by the first party (210), thereby generating an output y1' of the block-cipher E, and comparing the generated output y1' with the output y1 published by the first party (210).

Abstract: Embodiments of the invention provide a method of identifying entities from different data sources as matching entity pairs that refer to the same real-world object. With regard to a reduction of time and effort required to identify all possible matches from two heterogeneous data sources, the method comprises providing a set of labelling functions to determine the matching entities and the non-matching entities of a source data set (102) and a least one target data (104) set; selecting, from the provided set of labelling functions, a subset of labelling functions for training machine learning models for a blocking module (106) that aims at filtering out as many unmatched entity pairs as possible without missing any true matches and for a matching module (108) that aims at predicting matching results for the remaining entity pairs not filtered out by the blocking module (106); and jointly learning both a blocking model for the blocking module (106) and a matching model for the matching module (108) based on the available unlabeled entity pairs and the labelling functions of the selected subset of labelling functions.

Abstract: A computer-implemented method for event sequence forecasting of a process instance is disclosed. The method comprises building up and training a three- layered prediction model (160) including a first, a second and a third layer. The first layer is a graph embedding layer that assigns a fixed-dimensional graph embedding vector to each node and relation type in a fused event and knowledge graph (200) that contains available structural information including events, knowledge graph nodes, and the links between them. The second layer is an event embedding layer that assigns to each event of the process instance a fixed-dimensional event embedding vector. The third layer is a prediction layer that receives as input a sequence of event embeddings from the second layer and that generates as output a prediction of an unknown property of the event sequence used as input.

Abstract: A method for monitoring of a physical environment's proneness to infectious disease transmission, the method comprising: - in a training phase: obtaining unlabeled sensor data from sensors of the physical environment in order to provide a set of sensor features; generating, in particular by applying situation labeling functions, a labeling matrix that is fed to a generative model, wherein said generative model feeds a discriminative classifier model with probabilistic labels for the sensor features, wherein the probabilistic labels of the generative model are used for training the discriminative classifier model; determining, in particular by a feature selection optimizer entity, a subset of the sensor features based on an optimization procedure; and - in an operational phase: using, by the discriminative classifier model, the subset of sensor features for detecting predefined situations, which make the physical environment prone to infectious disease transmission. Furthermore, a corresponding system monitoring of a physical environment's proneness to infectious disease transmission is disclosed.
