Abstract: Aspects of the disclosure include an architecture for cross task large language model fine-tuning based on a shared context and methods of using the same. An exemplary method includes receiving a pre-trained large language model and receiving a set of fine-tuning tasks for the pre-trained large language model. The set of fine-tuning tasks includes at least a first fine-tuning task and a second fine-tuning task. The method includes generating, from the set of fine-tuning tasks, a first task combination including a subset of the set of fine-tuning tasks, identifying a shared subspace within the subset of the set of fine-tuning tasks, and responsive to identifying the shared subspace, fine-tuning the pre-trained large language model jointly over the first task combination.

Abstract: Disclosed are a molecular imaging method using Raman spectra and system based on machine learning cascade. The system includes a coordinate localization module, a hierarchical clustering analysis module, a Raman predictive imaging module, and a similarity analysis module. An untreated frozen tissue slice is attached to a stainless steel slide, and an adjacent slice is attached to a glass slide. The coordinate localization module can match a Raman white light image of a detection sample attached to the stainless steel slide with an immunohistochemistry (IHC) image of the adjacent slice, such that Raman spectra of a target region are accurately collected. The hierarchical clustering analysis module purifies different types of Raman spectra. A machine learning classifier is configured to build a Raman predictive imaging model. The similarity analysis module can evaluate similarity between a predicted Raman predictive image and the IHC image of the adjacent slice.

Abstract: The environmental-friendly antifouling agent includes a furan oxime and/or furan oxime metal complex, which has not only good antifouling performance, low toxicity and high efficiency and environmental friendliness. The ecological toxicity of the non-target organism is less than 15% of that of metals such as copper and chromium and organic matters such as benzoxazole, and the excellent barrier property of the furan ring structure itself on small molecules such as oxygen and water vapor can also significantly improve the barrier effect of a coating on a typical corrosive factor. The antifouling agent combined with an antifouling coating system can greatly improve the corrosion resistance of the coating system. Meanwhile, such the antifouling agent is easy to synthesize, can be well compatible with self-polishing resins, corrosion type resins and the like.

Abstract: An error management system for a data storage device can generate soft-decision log-likelihood ratios (LLRs) using multiple reads of memory locations. Bit patterns provided by multiple reads of reference memory locations can be counted and used to generate probability data that is used to generate possible LLR values for decoding target pages. Possible LLR values are stored in one or more look-up tables.

Abstract: A system and method for long term data retention in a flash memory. In some embodiments, the method includes transitioning the flash memory to a long term data retention state by re-storing first encoded data, the first encoded data being initially stored in the flash memory at a first code rate. The re-storing may include determining a second code rate, lower than the first code rate; reading the first encoded data from the flash memory; decoding the first encoded data at the first code rate to obtain first decoded data; encoding the first decoded data at the second code rate to form second encoded data; and storing the second encoded data in the flash memory.

Abstract: A system and method for adaptive multiple read of NAND flash memory. A solid state drive may employ adaptive multiple-read to perform enhanced performance error correction using soft decisions without a performance penalty that otherwise might result from performing unnecessary reads. The soft decision error correcting algorithm may employ lookup tables containing log likelihood ratios. The method may include performing one or more read operations to obtain one or more raw data words for a code word, attempting to decode the code words using the one or more raw data words, and performing additional read operations when the decoding attempt fails. This process may be repeated until a decoding attempt succeeds.

Abstract: A system and method for providing consistent performance in a storage device, such as a solid state drive. A threshold value for command execution time for a command in a category of command (e.g., a read command or a write command) and a command size, is stored in the storage device. When a host command in the category (e.g., a read command) and corresponding size is received, the storage device executes the command, and if it completes execution of the command in a time that is less than the threshold value, the solid state drive waits until an amount of time equal to the threshold value has elapsed before sending the command completion.
