Example 26 with structures._User

use of structures._User in project IR_Base by Linda-sunshine.

the class WeightedAvgAdapt method constructUserList.

@Override
void constructUserList(ArrayList<_User> userList) {
    int vSize = m_dim;
    // step 1: create space
    m_userList = new ArrayList<_AdaptStruct>();
    for (int i = 0; i < userList.size(); i++) {
        _User user = userList.get(i);
        // we will not create transformation matrix for this user
        m_userList.add(new _CoLinAdaptStruct(user, -1, i, m_topK));
        // Initiate user weights with global weights.
        user.setModel(m_gWeights);
    }
    m_pWeights = new double[m_gWeights.length];
    // huge space consumption
    _CoLinAdaptStruct.sharedA = new double[getVSize()];
    // step 2: copy each user's weights to shared A(weights) in _CoLinAdaptStruct
    for (int i = 0; i < m_userList.size(); i++) System.arraycopy(m_gWeights, 0, _CoLinAdaptStruct.sharedA, vSize * i, vSize);
}

Example 27 with structures._User

use of structures._User in project IR_Base by Linda-sunshine.

the class CLinAdaptWithKmeans method loadUsers.

// Initialize the weights of the transformation matrix.
@Override

    int totalUserSize = userList.size();
    // step 1: create space
    m_userList = new ArrayList<_AdaptStruct>();
    for (int i = 0; i < userList.size(); i++) {
        _User user = userList.get(i);
        m_userList.add(new _CLinAdaptStruct(user, m_dim, i, totalUserSize, m_clusterSize));
    }
    m_pWeights = new double[m_gWeights.length];
    // step1: init the shared A: individual + cluster + global
    _CLinAdaptStruct.sharedA = new double[getVSize()];
    for (int i = 0; i < m_userList.size() + m_clusterSize; i++) {
        for (int j = 0; j < m_dim; j++) {
            _CLinAdaptStruct.sharedA[i * m_dim * 2 + j] = 1;
        }
