The intermediate Palomar Transient Factory (ATel #4807) reports the discovery and classification of the following core-collapse SNe.

Our automated candidate vetting to distinguish a real astrophysical source (1.0) from bogus artifacts (0.0) is powered by three generations of machine learning algorithms: RB2 (Brink et al. 2013MNRAS.435.1047B), RB4 (Rebbapragada et al. 2015AAS...22543402R) and RB5 (Wozniak et al. 2013AAS...22143105W). See ATel #7112 for additional details.

The classification spectra and additional details are made publicly available through WISeREP (Yaron & Gal-Yam 2012) and the Transient Name Server.
