Typically, precision will increase and recall decrease, as you increase the threshold: for example, if you set the threshold to 0.9, your model will predict 1 only when 1 has a much higher likelihood than 0, so ...
WebMay 2, 2024 · The logistic regression assigns each row a probability of bring True and then makes a prediction for each row where that prbability is >= 0.5 i.e. 0.5 is the default threshold. Once we understand a bit more about how this works we can play around with that 0.5 default to improve and optimise the outcome of our predictive algorithm. WebThe threshold must be set in the linear phase of the amplification plot in Figure 1C. The C t value increases with a decreasing amount of template. However, artifacts from the reaction mix or instrument that change the fluorescence measurements associated with the C t calculation will result in template-independent changes to the C t value.
