Patent GB-2541649-A (GB)
Title: User feedback for machine learning
Inventor: SIMON KAMPA
IPC: G06N5/02
Filed: 2015-08-21
Abstract: An anomaly detection model is optimised by presenting a dataset where determined anomalies are identified and receiving informal user feedback indicative of a users like or dislike preference. For example, data points 35a and 35b determined to be anomalies are highlighted on a display screen 2 comprising a graphic user interface (GUI). A user can select a level of preference via like button 32 or dislike button 31. The feedback is used to update unsupervised anomaly detection algorithms, such that a model is brought closer to users preference. Fitness rating indicates the success of the model at identifying anomalies in an iterative process. Multiple weighted users can provide their feedbacks, e.g. users with two models of accelerometer on the same model of vehicle. Data can be derived from internet connected sensors or Internet-of-Things (IoT) sensors. Feedback is non-binary absolute or comparative. Advantages include obtaining feedback from non-technical users.

Title: Colour conversion
Inventor: CLIVE HENRY GILLARD
IPC: H04N9/64
Filed: 2015-09-08
Abstract: Colour conversion comprising: mapping pixels of an input image in an input colour space to pixels of a mapped image in a different output color space; processing the mapped image by detecting any mapped pixels that have negative colour components and for each mapped pixel with negative colour components, increasing all the colour components of that pixel by the magnitude of the largest negative colour component for that pixel; generating pixels of an output image in the output colour space from pixels of the processed mapped image; wherein colour components of the pixels in the output image are inhibited from exceeding a maximum representable colour amount. Scaling may limit the colour range depending on the largest colour component of a pixel. Gain and offset may be applied to all colour components of a pixel. Pixel luminance may be detected and a knee curve mapping applied. Colour transformation may be performed in a camera. The invention may help prevent undesirable changes in hue, brightness, luminance and saturation by avoiding truncation or clipping of the colour gamut.

Title: A method for allocating memory
Inventor: JAMES CROSBY
IPC: G06F12/02
Filed: 2016-01-19
Abstract: Discontinuous call stacks are allocated more efficiently in embedded systems without memory management units. A stack-space allocator allocates next stack frame Y and interrupt allowance Z either in current memory block K or in new block L if the amount of memory required is less/greater than the free space in current block K, respectively. Block K and the beginning of available (or end of used) space are indicated by a stack location indicator in a stack pointer register FSP comprising the top of the discontinuous call stack and updated at allocation. Following allocation, L becomes the current block while K becomes the previous block. Current block L also stores a previous location indicator PREV for a previous memory block of the call stack, e.g. the address of last used byte (or first free word) in K. PREV links the blocks discontinuously. Alternatively, reserved memory blocks for interrupts are used.
