  abstract = {{H}igh-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. {E}ven with the recent detection of extraterrestrial high-energy neutrinos by the {I}ce{C}ube experiment, no astrophysical neutrino source has yet been discovered. {T}ransient sources, such as gamma-ray bursts, core-collapse supernovae, or active galactic nuclei are promising candidates. {M}ulti-messenger programs offer a unique opportunity to detect these transient sources. {B}y combining the information provided by the {ANTARES} neutrino telescope with information coming from other observatories, the probability of detecting a source is enhanced, allowing the possibility of identifying a neutrino progenitor from a single detected event. {A} method based on optical and {X}-ray follow-ups of high-energy neutrino alerts has been developed within the {ANTARES} collaboration. {T}his method does not require any assumptions on the relation between neutrino and photon spectra other than time-correlation. {T}his program, denoted as {TAT}o{O}, triggers a network of robotic optical telescopes ({TAROT} and {ROTSE}) and the {S}wift-{XRT} with a delay of only a few seconds after a neutrino detection, and is therefore well-suited to search for fast transient sources. {T}o identify an optical or {X}ray counterpart to a neutrino signal, the images provided by the follow-up observations are analysed with dedicated pipelines. {A} total of 42 alerts with optical and 7 alerts with {X}ray images taken with a maximum delay of 24 hours after the neutrino trigger have been analysed. {N}o optical or {X}-ray counterparts associated to the neutrino triggers have been found, and upper limits on transient source magnitudes have been derived. {T}he probability to reject the gamma-ray burst origin hypothesis has been computed for each alert.},
