Abstract: A method for establishing robust prediction model is adapted for solving the problem that the conventional prediction model cannot generate stable and credible results with missing data. The method of the present invention includes the following steps: obtaining pre-established single-modality standard models respectively based on each type of modalities from samples; extracting modality sets each having the same modality types from the samples to establish corresponding multi-modalities standard models; extracting multiple combinations of the modality sets from the samples having complete modalities to be training data, wherein the multiple combinations of the modality sets can be classified into single-modality, multi-modalities and complete-modalities; inputting said training data into a to-be trained prediction model, and modifying the prediction model by said single-modality standard models and said multi-modalities standard models to obtain a well-trained prediction model.

Abstract: An amplifier circuit and a method of signal amplification are provided. The amplifier circuit includes a first amplifier and a charge pump. The first amplifier includes a first terminal, a second terminal, and a third terminal. The first terminal is coupled to a first external voltage. The second terminal is coupled to a negative voltage. The third terminal is coupled to a ground reference voltage. The charge pump is coupled to the first amplifier for providing the negative voltage transformed from a second external voltage.
