$i,j,k$ Values of the $\Theta$ Matrix in Neural Networks SO I'm looking at these two neural networks and walking through how the $ijk$ values of $\Theta$ correspond to the layer, the node number. 
Either there are redundant values or I'm missing how the subscripts actually map from node to node.
$\Theta^i_{jk}$ ... where this is read as " Theta superscript i subscript jk "
As shown here:

It looks like the $\Theta$ value corresponding to the node circled in teal would be $\Theta^2_{12}$ ... where:


*

*superscript $i=2$ ( layer 2 ) 

*$j=1$ ( node number within the subsequent layer ? ) 

*$k=2$ ( node number within the current layer ? )


If I'm matching the pattern correctly I think the $j$ value is the node to the right of the red circled node ... and the $k$ value is the teal node...
Am I getting this right?
Because between the above image and this one:

That seems to be the case ... can I get a confirmation on this?

Yes, $\Theta^i_{jk}$ is the weight that the activation of node $j$ has in the previous input layer $j - 1$ in computing the activation of node $k$ in layer $i$.
