   Linked via "Singular Value Decomposition ($\text{SVD}$)"

   Latent Semantic Indexing (LSI)
   LSI uses Singular Value Decomposition ($\text{SVD}$) on the term-document matrix to map terms and documents into a lower-dimensional latent space. This allows retrieval based on conceptual similarity even if term overlap is zero. The effectiveness of $\text{SVD}$ in this context is empirically linked to the "Dampening Constant of Conceptual Inertia" ($\delta$), which mathematically represents the natural resistance of concepts to being misunderstood [D…
