According to the first aspect, there is provided a method for training a machine learning classifier to detect contentious content, the method comprising the steps of: receiving content data 102 as input data; receiving annotation data 104 for said content; receiving metadata 106 in relation to said annotation data; and determining a learned approach to classifying whether the content is contentious based on said annotation data for said content and said metadata in relation to said annotation data. The method may receive further content as input data; determine a classification whether the further content is contentious using the classifier and further determining the learned approach to a high degree of certainty. The content may be generated online. The method may comprise reviewing the source of the content, reviewing the relationship between the source of the content and the user, reviewing the domain from which the content was generated, reviewing the profile and user history of the author of the content and/or performing natural language processing.

Title: Non-inverting differential amplifier with configurable common-mode output signal and reduced common-mode gain
Inventor: PAUL M WERKING
IPC: H03F3/45
Filed: 2018-03-19
Abstract: A fully differential amplifier circuit (differential output) 80 includes first and second amplifiers (e.g. operational amplifiers, op-amps) 82, 84 configured to amplify a differential input signal with a non-inverting gain and a third, transconductance, amplifier 86 providing feedback. The first and second amplifiers respectively receive first and second components VIN1, VIN2 of the differential input signal at their non-inverting inputs and provide components of a differential output signal VOUT1, VOUT2 at their respective output nodes 92, 98. The third amplifier has a non-inverting input node coupled to the output nodes of the first and second amplifiers, and an inverting input node receiving a reference signal Vcm. The third amplifier output is coupled to at least one of the first and second amplifier inverting input nodes. In an alternative arrangement the third amplifier, which may be a transconductance amplifier, causes the first and second amplifiers to generate a common-mode output signal related to the received reference signal. A method includes generating a differential output signal by amplifying a differential input signal with a non-inverting gain, and generating a common-mode output signal by amplifying a common mode input signal with a gain less than unity. The amplifier circuit may be used in applications where a reduced common-mode gain is desirable in addition to the high input impedance and low noise factor typically provided by non-inverting differential amplifiers.

Title: System and method for identifying fluid retention in a body part
Inventor: SHAMUS LOUIS GODFREY HUSHEER
IPC: G06T7/00
Filed: 2018-08-31
Abstract: A method of identifying fluid retention in a body part of the patient by directly or indirectly measuring, possibly using a depth sensor camera having at least two detector arrays, a first parameter relating to a size of a body part of the patient to obtain an actual measurement of the body part. This measurement is compared with an estimated measurement of said first parameter relating to the size of the body part of the patient by measuring alternative predefined parameters of the patient, wherein said estimated measurement is calculated based on a mathematical relationship between said alternative parameters and the size of the body part and correlating the actual and estimated measurements of the body part of the patient to assess any fluid retention in the body part. The measurement of the first parameter may be carried out by associating a 3D image of the body part with a 3D model of the body part. The method may also involve extracting both sets of measurements substantially simultaneously using a mathematical modelling system to provide an actual model and an estimated model based on population derived parameters for some of the model parameters and comparing the models to identify fluid retention in the body part. Furthermore, the first model may be obtained by providing a deformable model with morph parameters based on the actual body part and the second model being based on the body part without any fluid retention.
