  • Publication number: 20230005620
    Abstract: A computer-implemented method for identifying one or more patients at risk of having an undetected ophthalmic condition is described. The method may make use of non-ophthalmic data; pre-process the data to generate a culled dataset. The model may be trained and tested based on separate portions of the culled dataset. Finally the model may output, based on the analyzing the data, an indication of the existence or non-existence of one or more ophthalmic conditions.

  • Patent number: 9977598
    Abstract: The present invention provides a method for managing memory space in an electronic device including: selecting a candidate page from a first memory space for swapping the candidate page out of the first memory space into the second memory space; compressing the candidate page to obtain a first compressed page and a first hash value of the first compressed page; performing a comparison using the first hash value of the first compressed page and the hash values of the pages stored in a second memory space to find whether the pages have the same content as the first compressed page or the candidate page; and if a page is found to have the same content as the first compressed page or the candidate page, mapping a virtual address of the first compressed page or the candidate page to the found page.

  • Publication number: 20170060736
    Abstract: Methods and apparatuses pertaining to dynamic memory sharing may involve sharing a first portion of a memory associated with a first module for use by a second module. The first portion of the memory may be reclaimed for use by the first module in real time upon a determination that there is an increase in demand for the memory by the first module that requires reclamation, such that the first module begins to use the first portion of the memory before the second module finishes a process of aborting to use the first portion of the first memory.

  • Publication number: 20160098203
    Abstract: Techniques and implementations pertaining to a heterogeneous swap space with dynamic thresholds are provided. A technique may provide a list of a plurality of swap areas in a heterogeneous swap space. The swap areas may include at least two swap areas that are different from each other in one or more characteristics. The technique may also compute a dynamic threshold associated with a page in need of swapping and determine a priority level of the page in need of swapping based on the dynamic threshold. The technique may further select one of the swap areas from the list of swap areas for the swapping of the page in response to a determination of the priority level of the page.
