take the same approach to item tags, using latent factors xᴵₐ ∈ Rᶠ and bias terms bᴵₐ ∈ R. Once we have defined pᵤ, qᵢ, bᵤ, bᵢ using these formulas, we can use the same linear model of SVD to describe the relationship between these terms and rᵤᵢ. LightFM: user/item embeddings and biases are the sum
