   • What algorithm to use to segment a sequence of numbers into n subsets, to minimize the standard deviation of the sum of the numbers in each subset

     Top Answer

     Answered Jan 30, 2010 · 9 votes

     Suppose the length of the original sequence is L and the number of subsequences is N.

     You may simplify the expression for standard deviation to get sqrt(E[X^2] - E[X]^2), where E denotes expectation/average and X denotes your random variable -- in your case, the sum of the subsequences. (A similar formula applies for the "sample standard deviation".) Note that E[X] does not depend on how you split your sequence, because it will always be the total sum divided by N. Thus, we just want to minimize E[X^2] or equivalently, the sum of X^2 (they differ by a factor of N by the definition of average).

     At this point, we can see that this problem can be solved with dynamic programming. Let f(i,j), for i from 0 to M and j from 1 to N, be the minimal sum of squares of sums of subsequences from the split of the first i elements of your sequence into j subsequences. Then we see that f(i,j) may be computed in terms of all the f(i',j') with i' <= i and j < j'. More specifically, if your sequence is a[k] indexed from 0 to M-1:

     f(i,1) = sum( a[k] for 0 <= k < i )^2f(i,j) = minimum of f(l,j-1)+sum( a[k] for l < k < i )^2 for l from 0 to i-

     Having minimized f(N,L), you can use standard dynamic programming techniques to recover the splits. In particular, you can store the l that minimizes f(i,j).

     The runtime of this solution is O(L^2 N) because you compute O(L N) different values of f and the minimum is over O(L) different values of l.

     Here's a straightforward implementation in Perl:

     #!/usr/bin/perl-use strict;use warnings;-local $\ = $/;print join ", ", map {"@$_"} best( 2, qw(1 1 1 1 1 1 10 1) );# prints "1 1 1 1 1 1, 10 1"-print join ", ", map {"@$_"} best( 3, qw(4 1 1 1 1 6) );# prints "4, 1 1 1 1, 6"-sub best { my( $N, @a ) = @_;- my( @f, @g, $i, $j, $k, $sum );- # DP base case $sum = 0; $f[0][1] = $g[0][1] = 0; for $i ( 1 .. @a ) { $sum += $a[$i-1]; $f[$i][1] = $sum * $sum; $g[$i][1] = 0; }- # DP recurrence for $j ( 2 .. $N ) { $f[0][$j] = $g[0][$j] = 0; for $i ( 1 .. @a ) { $sum = 0; $f[$i][$j] = $f[$i][$j-1]; $g[$i][$j] = $i; for $k ( reverse 0 .. $i-1 ) { $sum += $a[$k]; if( $f[$i][$j] > $f[$k][$j-1] + $sum * $sum ) { $f[$i][$j] = $f[$k][$j-1] + $sum * $sum; $g[$i][$j] = $k; } } } }- # Extract best expansion my( @result ); $i = @a; $j = $N;- while( $j ) { $k = $g[$i][$j]; unshift @result, [@a[$k .. $i-1]]; $i = $k; $j--; }- return @result;}-

   • What kind of algorithm is behind the Akinator game?

     Top Answer

     Answered Nov 30, 2012 · 24 votes

     Yes, there is a name for these class of algorithms - it is called classification algorithms in the field of machine learning. Decision trees is one example for classification algorithm.

     In this classification problem, the features for the algorithm are the answers to the question.

     Deciding which question should be asked next can be done in various ways - for example by trying to maximize the predicted (or mean) entropy from the next question.

     I found a solution: it's here.

     The idea is to make use of vector algebra, to use the dot and cross to simply the question until this stage:

     a (V1 X V2) = (P2 - P1) X V2-

     and calculate the a.

     Note that this implementation doesn't need to have any planes or axis as reference.

   • What does the dist attribute of the kamada_kawai_layout in networkx mean and how can I use that attribute to control the spacing of my graph?

     Top Answer

     Answered Oct 22, 2019 · 3 votes

     The function expects a dictionary of the form dist['source']['target'] = distance.

     As you can see in the code, if dist is omitted the function takes the result of dict(nx.shortest_path_length(G, weight=weight)). shortest_path_length returns an iterator over pairs (source, distances), where distances is a dict mapping target nodes to distances.

     Note that the function does not assume distances to be symmetric! If you define only the distance from 'u' to 'v' to be 100.0 (i.e. only dist['u']['v'] = 100.0), the distance from 'v' to 'u' is assumed to be 1000000 (see definition of dist_mtx in the definition of the function).
