Abstract: One or more techniques for optimizing cancer classification based on covariate characteristics is disclosed. In a first approach, an analytics system may determine separate cutoff thresholds for positively detecting disease signal for different labels for a covariate characteristic. The system may subdivide training samples based on their labels for the covariate characteristic, to separately determine the cutoff thresholds. In other approaches, the system may train disparate classifiers for each population. The system separates the training samples based on their labels for the covariate characteristic, and separately trains classifiers to generate a signal vector representing an amount of disease signal detected in a sample. The classifiers may be trained on different feature sets as determined based on mutual information gain, genomic region coverage, and healthy activation fraction.

Abstract: A computer system displays a representation of a field of view of the one or more cameras, including a representation of a portion of a three-dimensional physical environment that is in the field of view of the one or more cameras. The computer system receives a request to add a first virtual effect to the displayed representation of the field of view of the one or more cameras. In response to receiving the request to add the first virtual effect to the displayed representation of the field of view of the one or more cameras and in accordance with a determination that the first virtual effect requires a scan of the physical environment, the computer system initiates a scan of the physical environment to detect one or more features of the physical environment and displays a user interface that indicates a progress of the scan of the physical environment.

Abstract: Of the four primary approaches to processing language by computer, only the parsing approach considers the semantic and syntactic components from the start. In doing so, however, the required resources expand rapidly as the scope of the language processed increases. And as that scope increases, the performance of parsing systems decreases. A natural language processor uses a tumbling-frequency phrase chain parser as described herein which circumvents this resource-intensive step in parsing, while quickly and almost effortlessly arriving at the next step in natural-language processing with far more accurate results involving a partitioning dictionary and phrase chains.

Abstract: This disclosure concerns improved capabilities for evaluating whether additional medical tests need to be conducted for a diagnosis of a pulmonary arterial hypertension (PAH) condition in a patient. The method includes determining that the patient is at rest and measuring a partial pressure of carbon dioxide in a composite gas, comprising: transferring an expiration from the patient's mouth to a carbon dioxide analyzer; measuring end tidal carbon dioxide (EtCO2) from each of a plurality of oral expirations from the patient; and calculating a composite EtCO2 value. The method further includes comparing the composite EtCO2 value to a range of stored carbon dioxide partial pressure values; generating a signal indicating whether additional medical tests need to be conducted in response to the comparing; and providing the generated signal to an indicator, the indicator adapted to respond to the generated signal to provide an output in a human cognizable format.
