DerMAE: Improving skin lesion classification through conditioned latent diffusion and MAE distillation
Francisco Filho, Kelvin Cunha, Fábio Papais +6
Skin lesion classification datasets often suffer from severe class imbalance, with malignant cases significantly underrepresented, leading to biased decision boundaries during deep…
DermAI: Clinical dermatology acquisition through quality-driven image collection for AI classification in mobile
Thales Bezerra, Emanoel Thyago, Kelvin Cunha +9
AI-based dermatology adoption remains limited by biased datasets, variable image quality, and limited validation. We introduce DermAI, a lightweight, smartphone-based application t…
Fast Radix-32 Approximate DFTs for 1024-Beam Digital RF Beamforming
A. Madanayake, R. J. Cintra, N. Akram +6
The discrete Fourier transform (DFT) is widely employed for multi-beam digital beamforming. The DFT can be efficiently implemented through the use of fast Fourier transform (FFT) a…
Varieties with one apparent double point
C. Ciliberto, M. Mella, F. Russo
The number of apparent double points of a smooth, irreducible projective variety of dimension in $\Proj^{2n+1}$ is the number of secant lines to passing through the gen…
