Autonomous exploration in complex multi-agent reinforcement learning (MARL) with sparse rewards critically depends on providing agents with effective intrinsic motivation. While artificial curiosity offers a powerful self-supervised signal, it often confuses environmental stochasticity with meaningful novelty.

Science Space Solar System Mars For 6 days, NASA's Mars rover battled a rock More information Adding us as a Preferred Source in Google by using this link indicates that you would like to see more of our content in Google News results. The multi-day challenge took multiple attempts to fix. Breakthroughs, discoveries, and DIY tips sent six days a week. Curiosity got itself stuck between a rock and hard place last month, but NASA says there's no reason to fret about the intrepid Mars rover . On April 25, mission engineers were remotely piloting its robotic arm's rotary-percussive drill into a Martian rock nicknamed Atacama.

NASA's Curiosity Mars rover took this selfie at a location nicknamed Mary Anning after a 19th century English paleontologist. This was the site of the chemical experiment uncovering diverse organic molecules on Mars, in the Glen Torridon region, which scientists believe was a site where ancient conditions would have been favorable to supporting life, if it ever was present. Breakthroughs, discoveries, and DIY tips sent six days a week.

Higgs Boson breakthrough was UK triumph, but British physics faces'catastrophic' cuts When the Nobel Prize in Physics was announced in Stockholm in October 2013, the world was watching. Among the names read out was Prof Peter Higgs, the British theorist who, nearly half a century earlier, had predicted the existence of a particle believed to hold the cosmos together - the Higgs boson. The announcement, broadcast live from Sweden, was what many scientists had hoped for since a year earlier, when experiments at CERN had finally confirmed Higgs's theory by discovering the Higgs boson - hailed as one of the biggest discoveries in a generation. At the time Higgs, who has since passed away, said in a statement: I hope this recognition of fundamental science will help raise awareness of the value of blue-sky research. Blue-sky research asks questions to understand the universe, rather than design new products.

We use the same hyperparameters as in large scale curiosity: a learning rate of 0.0001 for all models, a discount factorγ of 0.99, and 3 optimization epochsperrollout. Here we present results on using audio in baselines, as described in the main paper ablations section. In the first baseline, the prediction space is concatenated audio and visual features: the intrinsic model takes an audio-visual feature vector as input and predicts an audio-visual feature vector as output. The results from the audio-visual prediction baseline are shown in Figure 9. In the second baseline, we add audio to randomnetworkdistillation[35].

Acommon formulation of curiosity-driven exploration uses the difference between the real future and the future predicted by a learned model [1].

The reborn Commodore 64 is an astonishing remake--but daunting if you weren't there the first time around. "Digital detox" approach is compelling. It's hard to overstate just how seismic an impact the Commodore 64 had on home computing. Launched in 1982, the 8-bit machine--iconic in its beige plastic shell with integrated keyboard--went on to become the best-selling personal computer of all time . Despite the success, manufacturer Commodore International folded in 1994, with rights to the name floating around for years.
