H5N1-R1
The primers were designed using NCBI BLAST and SanpGene to achieve efficient and specific amplification. This primer in RPA serves as the initial binding point for the amplification process, ensuring the specificity of the reaction by targeting the desired Influenza A virus(2004H5N1) DNA or RNA sequences. The primers provided data for mathematical modeling for further primer design.

Figure 10. Linear graphs and figures (a) correspond to the fluorescence intensity of crRNAs targeting H5N1 after one-tube reaction of RPA and CRISPR under Bright and UV illumination. No crRNA is added into negative control. The concentration of DNA template is 10nM/L.
Machine Learning
In the initial phase, we trained the model with a limited dataset of 74 data points, followed by an evaluation that proved that the support vector machine model fits into the evaluation.
Subsequently, during the second round, our focus shifted to fine-tuning the SVM model parameters. Notably, this round of training also relied on the same 74 data points. It is pertinent to mention that both the first and second rounds of training and evaluation employed randomly partitioned datasets.
In the third round, our model made predictions for the performance of 40 entirely new primers, which were unlabeled. The practical utility of these predictions was validated through experimental verification, confirming the high accuracy and reliability of our model. The alignment between the predicted class and the experimental class was particularly strong.
This approach effectively underscores the potential of machine learning to reduce the number of experiments required.
