Is this a bug?

[吴晨阳]

loss(\mathbf{y},\mathbf{\hat{y}})=\frac{1}{n}\sum_{i=1}^{n}(y_i-\hat{y_i})^2

By inputing this formula, the actual effect I got in Freeplane is the same as

loss(\mathbf{y},\mathbf{\hat{y}})=\frac{1}{n}\sum\_{i=1}^{n}(y\_i-\hat{y_i})^2

hi,

did you put your formula in $...$? Just like in LaTeX, freeplane puts you in text mode by default.

Cheers and Best Regards,
Felix
