why do we optimize k means why isn't k-means optimized using gradient descent why is k a stochastic or stochastic method why are k mean optimizations used why is it called gradient descent for k-means why is k mean optimized using gradient descent why is k-means not optimized when do we optimize k-mesh why isn't k-means optimized using gradient descent? why is k-means not optimized using gradient descent? why is k means optimized using gradient descent why does uncertainty optimization optimize k-means why isn't k mean optimized using gradient descent? why is k-mean optimization done using gradient descent why is k-means optimized using gradient descent? why isn't k-means optimized using gradient descent why is it not possible to optimize k-means using gradient descent why should we optimize k-means using gradient descent why is k-means optimized using gradient descent why is k mean optimized using gradient descent
