- 배열 접기문제 www.codewars.com/kata/fold-an-array Fold 1-times: [1,2,3,4,5] -> [6,6,3] A little visualization (NOT for the algorithm but for the idea of folding): Step 1 Step 2 Step 3 Step 4 Step5 5/ 5| 5\ 4/ 4| 4\ 1 2 3 4 5 1 2 3/ 1
- Clustering with K-Means and EM: how are they related? There is no "k-means algorithm". One can consider Lloyds algorithm to consist of two steps: the E-step, where each object is assigned
- numeric demonstration of backpropagation Example: see sample applet The formula of sigmoid activation is: 1 f(x) = --------- 1 + e-input The algorithm rate * output error * output(neurons i) * output(neurons i+1) * ( 1 - output(neurons i+1) ) Go to step
