Abstract: This work addresses a procedure to estimate fundamental stellar parameters such as T_{eff}, log g, [Fe/H], and v sin i using a dimensionality reduction technique called principal component analysis (PCA), applied to a large database of synthetic spectra. This technique shows promising results for inverting stellar parameters of observed targets from Gaia Eso Survey.
