Printed | Page Page 499 Equation 15-2 |
In this equation, the bias vector is shown as `b`which has size n-neurons. However, this calculation is being made for a mini-batch. The other terms in the summation will have a dimension of m x n-neurons, similar to output Yt. Also, the previous equation implies that b is a column vector. So shouldn't `b` be changed to matrix B of same dimension where each row = b-transposed? |

Hi, it might very well be that I didn't quite follow but here it goes: Shouldn't the purple and green colours in Figure 6-2 be reversed? The decision tree is meant to classifiy any iris with less than petal width of 1.75 as versicolour. If that is the case, the colour on the chart should be green and not purple and vice versa for virginica so that it matches the colours on the previous page (Decision tree image). |

In Figure 9-10 the axis of the plots in the upper row seems not to be aligned with the axis of the lower row. I assume the same data as in Figure 9-9 is used: k=4 (upper right) seems to be worse than k=3 (upper left). |
