Aug 19, 2020 · You now have a basic grasp of how to create a prototype recommendation engine using matrix factorization in TensorFlow. This is a big deal. You can take this even further by learning other matrix factorization techniques such as Funk MF , SVD++ , Asymmetric SVD , Hybrid MF , and Deep-Learning MF or k-Nearest Neighbours approaches. Apr 13, 2018 · Generally, when changing a feature-value $x_i$ can cause the pattern or feature vector ${\bf {\it x}}$ to become assigned a different class label, then that feature-value is of importance: Feature-value $x_i$ is said to have potential influence for the classification of feature vector ${\bf {\it x}}$. Feature-values that have potential influence for a large number of (different) pattern vectors, they are important ones for the classification task at hand.
