F1 score = (2*precision*recall)/(precision+recall)

[@cromllo7162]

how did you get the answers in percentages?

[@notfixedcontent_12]

Multiply with 100

[@mjay5655]

i got 95 as the answer for F1

[@RoyBombale]

@@cromllo7162 multiply them into 100

[@Ramanikathiresan]

X 100​@@cromllo7162

If more than one model is present based on what we need to select one particular model ie based on high accuracy or precision or recall?

Can u please let us know when and which accuracy metric we can consider for our problem among accuracy, precision,recall and f1-score

[@Kirankumar-ze8ug]

❤🙏

[@abizarkhalil]

plz calculate WEIGHTED ACCURACY from the confusion matrix (two class)

Very much

but the accuracy when calculated is , 45.63333 .... how does it come 93.33 % to uh sir ?

[@MaheshHuddar]

You are wrong
Watch video one more time carefully

[@areejawan]

@@MaheshHuddar ans is 140/150 equals to 0.9333

[@notfixedcontent_12]

To get the value in presentage we need multiple with 100

[@jeevithasrinivasan3199]

45+95 = 140 ... 140/150 = 0.9333
0.933 * 100 = 93.33%

[@santoshkumarsahu8482]

When we prefer accuracy, precision, recall and f1 score??

What can we do for a big matrix 10*10
