Patent number: 11087860Abstract: In pattern discovery visual analytics, a patient data table (14) is generated that tabulates, for each patient, attribute values for a set of attributes. A positive or negative prediction is generated for each patient for a target value of a target attribute using a prediction pattern (20) of attribute values for w attributes (22). The prediction is positive if at least a threshold fraction (26) of the w attributes of the patient match the prediction pattern, is negative otherwise. Patients are grouped into a selected proportion of a confusion matrix (30) in accord with the positive or negative predictions and actual values of the target attribute T in the patient data table. A display component (4) displays a representation (42) of patient statistics for the selected proportion of the confusion matrix on a per-attribute basis for attributes of the w attributes. A patient cohort (44) is identified using the representation.Type: GrantFiled: October 19, 2016Date of Patent: August 10, 2021Assignee: Koninklijke Philips N.V.Inventors: Tak Ming Chan, Choo Chiap Chiau, Niels Roman Rotgans, Niels Laute, Jurriën Carl Gosselink, Johanna Marie De Bont

Patent number: 10849566Abstract: The present invention relates to an apparatus, a system (100), a method (200), and a computer program for assessing the risk of an exacerbation and/or hospitalization. A patient's physical activity is measured (e.g., by an accelerometer (110)) during an active period of time (e.g., during awake hours) and during a rest period of time (e.g., during sleep hours) to gather first and second activity data. A risk of exacerbation and/or hospitalization is assessed (e.g., by a risk assessment unit (120)) based on an expression involving the respective activity data during active and rest periods fulfilling a predetermined relationship with respect to a predetermined activity level. For instance, low activity data during active periods and high activity data during rest periods indicates an increased risk of exacerbation and/or hospital readmission for the patient.Type: GrantFiled: June 26, 2015Date of Patent: December 1, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Tamara Mathea Elisabeth Nijsen, Chevone Marie Barretto, Choo Chiap Chiau, Mareike Klee

Patent number: 10588127Abstract: A method of communicating between a primary station and a plurality of secondary stations is described. According to one aspect, the secondary station monitors a control channel search space for a control message from a primary station intended for the communication device. According to an aspect, the control message is indicative of a resource allocated to the secondary station for communicating with the primary station and the resource corresponds to a component carrier. The secondary station determines a control channel from the control channel search space having the control message intended for the secondary station and determines, based on a presence of the control channel on a specific component carrier, the indication of a resource set from a plurality of resources sets in which the resource allocated to the secondary station is located.Type: GrantFiled: January 29, 2018Date of Patent: March 10, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Timothy James Moulsley, Choo Chiap Chiau, Milos Tesanovic, Robert James Davies

Publication number: 20200051698Abstract: An electronic clinical decision support (CDS) device executes (54) clinical decision rules (8) using a computer (10, 12) to generate predicted values of clinical conclusions (58) for a current patient based on values for the current patient of preconditions of the clinical decision rules (52). The rules are also executed (36) to generate predicted values of the clinical conclusions (38) for past patients based on values for the past patients of the preconditions (32) retrieved from an Electronic Medical Record (EMR) (20). Rule summary scores (42) are generated (40) based on comparisons of “ground truth” values of the clinical conclusions (34) for the past patients retrieved from the EMR with the predicted values of the clinical conclusions for the past patients. A display (14) shows the predicted values of the clinical conclusions and the corresponding applied rules for the current patient ranked at least in part by the rule summary scores.Type: ApplicationFiled: October 18, 2017Publication date: February 13, 2020Inventors: Tak Ming Chan, Qin Zhu, Chun Qi Shi, Choo Chiap Chiau

Publication number: 20180342328Abstract: Presented is a concept for discovering a pattern in a dataset, where the dataset comprises a plurality of records, each record associated with a plurality of attribute values. The concept comprises defining a target attribute value and ascertaining a set of candidate attribute values based on the target attribute value. The set of candidate attribute values may be considered as a potential pattern in the dataset. For each record, the target attribute values and candidate attribute values are compared to the attribute values of that record so as to identify matching attribute values. A matching indicator is generated for each record based on a comparison between the number of matching attributes values and a matching threshold value, such that the matching indicator indicates a degree of similarity between the attribute values of the record and the set of candidate attribute values and the target attribute value.Type: ApplicationFiled: October 20, 2016Publication date: November 29, 2018Inventors: Tak Ming CHAN, Choo Chiap CHIAU
