  • Publication number: 20220237264
    Abstract: A computer-implemented method for analyzing data obtained for a chemical and/or biological process comprises: obtaining a result of statistical data analysis on the data obtained with respect to the chemical and/or biological process; calculating, for values of process parameters obtained at groups of time points during batch processes of the chemical and/or biological process, a ratio of a correlation value to a confidence value of the correlation value, the correlation value indicating a correlation between the values of the process parameter and at a process output value; calculating, for process parameters, an average of absolute values of the ratios calculated for the values of the process parameter obtained at different groups of time points during the batch processes; excluding the values of one of the process parameters having a smallest average; and iterating, until at least one specified condition is met.

  • Publication number: 20210383893
    Abstract: According to some aspects of the disclosure, a computer-implemented method, a computer program and a process control device for selecting at least one set of target cells from multiple sets of candidate cells are provided. The method can include receiving data collected from a plurality of processes, wherein each of the processes produces a distinct set of candidate cells. The method further comprises the received data including values of process outputs being a product quality attribute or a key performance indicator for selecting the target cells.

  • Patent number: 8725469
    Abstract: Described are computer-based methods and apparatuses, including computer program products, for optimizing data processing parameters. A data set is received that represents a plurality of samples. The data set is processed using a data processing algorithm that includes one or more processing stages, each stage using a respective first set of data processing parameters to generate processed data. A design of experiment model is generated for the data processing algorithm based on the processed data and a set of response values. For each stage of the data processing algorithm, a second set of data processing parameters is calculated based on at least the design of experiment model.
