Lossy Compression for Robust Unsupervised Time-Series Anomaly Detection
Christopher P. Ley, Jorge F. Silva
A new Lossy Causal Temporal Convolutional Neural Network Autoencoder for anomaly detection is proposed in this work. Our framework uses a rate-distortion loss and an entropy bottle…
On Universal D-Semifaithful Coding for Memoryless Sources with Infinite Alphabets
Jorge F. Silva, Pablo Piantanida
The problem of variable length and fixed-distortion universal source coding (or D-semifaithful source coding) for stationary and memoryless sources on countably infinite alphabets…
Compressibility Analysis of Asymptotically Mean Stationary Processes
Jorge F. Silva
This work provides new results for the analysis of random sequences in terms of -compressibility. The results characterize the degree in which a random sequence can be appr…
Visual binary stars with partially missing data: Introducing multiple imputation in astrometric analysis
Ruben M. Claveria, Rene A. Mendez, Jorge F. Silva +1
Partial measurements of relative position are a relatively common event during the observation of visual binary stars. However, these observations are typically discarded when esti…
Optimality of the Maximum Likelihood estimator in Astrometry
Sebastian Espinosa, Jorge F. Silva, Rene A. Mendez +2
The problem of astrometry is revisited from the perspective of analyzing the attainability of well-known performance limits (the Cramer-Rao bound) for the estimation of the relativ…
Orbits for eighteen visual binaries and two double-line spectroscopic binaries observed with HRCAM on the CTIO SOAR 4m telescope, using a new Bayesian orbit code based on Markov Chain Monte Carlo
Rene A. Mendez, Ruben M. Claveria, Marcos E. Orchard +1
We present orbital elements and mass sums for eighteen visual binary stars of spectral types B to K (five of which are new orbits) with periods ranging from 20 to more than 500 yr.…
