I don't think you are calculating the distances for updating the weights incorrectly

Hi, just a friendly note but I think it should be:

def updateWeights(weight_arr, C):
        denom = np.zeros(n)
        for i in range(n_clusters):
            
            dist = (X.iloc[:,:].values - centers[i])**2
            dist = np.sum(dist, axis=1)
            dist = np.sqrt(dist)
            dist = np.power(dist, 2) # I think this line is missing
            denom  = denom + np.power(1/dist, 1/(m-1))
            
        for i in range(n_clusters):
            dist = (X.iloc[:,:].values - centers[i])**2
            dist = np.sum(dist, axis=1)
            dist = np.sqrt(dist) # Up to here is the euclidean distance but for the equation for update the weights now squares the dist
            dist = np.power(dist, 2) # I think this line is missing
            weight_arr[:,i] = np.divide(np.power(1/dist, 1/(m-1)), denom)

  return weight_arr

I can't see your cell which has the equation for the computing the new weights - I'm not sure what is needed to fix that, I've never created an equation in a notebook cell....

(1 / (dist)^2)^(1/ (m-1)) / SUM(1 / (dist)^2)^(1/ (m-1))
