Goal
Understand the Express system and write code in go-lang to evaluate the existing system.
03
Tools
Programming Language is Python3 & go-lang. Write a report about the Express system.
Express - System:
- True Positive (TP):
- These are the cases where the model correctly predicts the positive class. In
other words, the actual positive instances and the model also predict them as positive.
$\Rightarrow 1300$
- False Positive (FP):
- These occur when the model incorrectly predicts the positive class. That
means the
instances are negative, but the model predicts them as positive, also known as a "Type I
error." $17 + 0 + 31 = 48$
- True Negative (TN):
- These are the cases where the model correctly predicts the negative class.
So, the model also predicts the negative instances as negative." $\Rightarrow 6808$
- False Negative (FN):
- occur when the model incorrectly predicts the negative class. That means the
instances are positive, but the model predicts them as negative, also known as a "Type II
error." $\Rightarrow 38$
