  • Publication number: 20250131915
    Abstract: Training a mixed language speech recognition model, and speech recognition performed by the model, can be enhanced. Model manager can control training and/or operation of the model. Mixed language data generation manager can generate an enhanced mixed language dataset that can enhance training of the model. Fine tuner can facilitate configuring hyperparameters of the model. Audio-based information and transcript that are representative of the dataset can be applied to the model to facilitate model training. FAL evaluator can determine fidelity, accuracy, and latency of performance of speech recognition on the audio-based information and transcript by the model. Based on such determination, mixed language data generation process and/or hyperparameters can be updated to enhance further training of the model to enhance fidelity, accuracy, and/or latency regarding performance of speech recognition by the model. Model manager can control one or more iterations of model training.

  • Patent number: 12258278
    Abstract: An organic-inorganic hierarchical ZSM-5, a preparation method thereof, and an application thereof are provided. The preparation method for the organic-inorganic hierarchical ZSM-5 includes the following steps: mixing a silicon source, an aluminum source, NaOH, and water, stirring the mixture until uniformly dispersed, and drying and grinding the mixture to obtain a hierarchical ZSM-5 precursor; mixing the hierarchical ZSM-5 precursor, sodium silicate, seed, ethanol, and water, and uniformly dispersing the mixture to obtain a crystallized solution; mixing the crystallized solution with a hydrolyzed organosilane to obtain a first solution; subjecting the first solution to hydrothermal crystallization at 160-180° C. for 48-72 h to obtain a second product; and washing and drying the second product to obtain the organic-inorganic hierarchical ZSM-5.

  • Patent number: 7804873
    Abstract: Electrically pumped surface emitting organic laser device having a multi-layer of organic materials disposed between a highly reflective microcavity mirror and a highly reflective mirror to thereby form a coupled microcavity. More specifically, the organic laser device includes a substrate; a bottom mirror over the substrate; a layer of spacer over the bottom mirror; a coupling mirror over the spacer layer; an anode over the coupling mirror; an active layer over the anode; a cathode over the active layer; and a top mirror over the cathode. The combination of the electrode and the mirror leads to low optical absorption and highly reflective electrical contacts at organic-electrode interfaces. Electroluminescent emission efficiency is improved due to the realization of efficient electron-injection and hole-injection. A low loss organic laser device with a coupled microcavity structure is realized that can produce surface emitting laser output under electrical pumping.
