Figure 3: Attention map and Raman spectra for classification of microbes, CHO cells, CHO cells with gram-negative, CHO cells with gram-positive and CHO cells with Fungus. The bold blue line indicates average spectra (6000 scans) and the shaded area around the bold blue line indicates standard deviation. The heatmap (yellow-orange) indicates the importance of the different segments of the spectra according to attention map. A. Aspergillus brasiliensis , B. Bacillus cereus , C. Bacillus subtilis , D. Candida Albicans , E. Clostridium sporogenes , F.Escherichia coli , G. Micrococcus luteus , H.Propionibacterium acnes, I. Pseudomonas aeruginosa , J.Salmonella enterica , K. Staphylococcus aureus , L.Staphylococcus epidermis , M. CHO cells. N. CHO cells andAspergillus brasiliensis , O. CHO cells and Bacillus cereus , P. CHO cells and Staphylococcus aureus .
