我有这个参数形式为word2vec_matlab,我想计算余弦相似距离
wordvecs_norm - Normalized word vectors
word2Index - Map of words to indeces
input - Input word (string)
k - Number of words to return
我试过
word1 = ('king');
word2 = ('queen');
cosine = dot(wordvecs(word1)/ wordvecs_norm(word1), wordvecs(word2)/ wordvecs_norm(word2));
答案 0 :(得分:0)
维基百科将此作为公式:https://en.wikipedia.org/wiki/Cosine_similarity
我认为这可以在MATLAB中转换为:
public void onItemSelected(AdapterView<?> parent, View view, int position,long id) {
//Appending the values to textview for a selected item
// textViewResult.setText("");
if(!getName(posission).equals("select a name"))
{
textViewResult.setText("Hi " + getName(position-1) + " your ID is " + getId(position-1));
} }
让我知道它是否有效!
