ALERT Town Beach Is CLOSED For Swimming Due To High Bacteria Count

first_imgWILMINGTON, MA — The Wilmington Recreation Department has announced that Silver Lake is currently CLOSED for swimming due to a high bacteria count detected in this week’s water testing.“To minimize the risk of illness from contaminated water, beaches are required to be tested for “indicator” bacteria ― bacteria that indicate the presence of fecal contamination,” reads the announcement. “Silver Lake is tested for Enterococci or E. coli. We had an exceedance this week, therefore the Beach is closed for swimming until a re-sample tests clear.”This is the lake’s first closure of the season, and it comes at an inopportune time. The Wilmington Police Association’s Beach Day is scheduled for this Thursday, August 1, from 11am to 2pm, at Town Beach.“The Police Beach Day is STILL ON with games, activities, DJ and lunch, but no swimming,” Recreation Director Karen Campbell told Wilmington Apple. “The beach will be retested on Friday.”Silver Lake is tested every Tuesday during beach season. The Recreation Department received these results late on Wednesday afternoon.Like Wilmington Apple on Facebook. Follow Wilmington Apple on Twitter. Follow Wilmington Apple on Instagram.

Deep reinforcement learning – trick or treat

first_imgDeep Reinforcement Learning (Deep RL) is the new buzzword in the machine learning world. Deep RL is an approach which combines reinforcement learning and deep learning in order to achieve human-level performance. It brings together the self-learning approach to learn successful strategies that lead to the greatest long-term rewards and allows the agents to construct and learn their own knowledge directly from raw inputs. With the fusion of these two approaches, we saw the introduction of many algorithms, starting with DeepMind’s Deep Q Network (DQN). It is a deep variant of the Q-learning algorithm. This algorithm reached human-level performance in playing Atari games. Combining Q-learning with reasonably sized neural networks and some optimization tricks, you can achieve human or superhuman performance in several Atari games. Deep RL resulted in one of the notable advancements in the game of AlphaGo.The AI agent by DeepMind was able to beat the human world champions Lee Sedol (4-1) and Fan Hui (5-0). DeepMind then further released advanced versions of their Agent called AlphaGO Zero and AlphaZero. Many recent works from the researchers at UC Berkeley have shown how both reinforcement learning and deep reinforcement learning have enabled the control of complex robots, both for locomotion and navigation. Despite these successes, it is quite difficult to find cases where deep RL has added any practical real-world value. The current status is that it is still a research topic. One of its limitations is that it assumes the existence of a reward function, which is either given or is hand-tuned offline. To get the desired results, your reward function must capture exactly what you want. RL has an annoying tendency to overfit to your reward, resulting in things you haven’t expected. This is the reason why Atari is a benchmark, as it is not only easy to get a lot of samples, but the goal is fairly straightforward i.e to maximize score. With so many researchers working towards introducing improved Deep RL algorithms, it surely is a treat.

Punta Cana will be a maiden port on Christmas Eve 2019. The ship will also offer a westward and eastward trans-Panama Canal voyage in March 2020 before returning to Europe in April.In Alaska, Seven Seas Mariner will return to the region from May through September 2019. The ship will cruise the Caribbean in October – making a maiden call on Acujulta (El Salvador) – before embarking on the 66-night South America circumnavigation voyage. After a Panama Canal transit from Miami, the 2020 world cruise begins on Jan. 24 from San Francisco fro a 131-night roundtrip journey.Seven Sea Voyager will return to the Mediterranean from April through October 2019, and then sail Asia and the South Pacific from November 2019 through March 2020. Travellers also can choose one of two Australia and New Zealand itineraries in January. Maiden ports include Kos (Greece), Calvi (Corsica, France), Miyazaki (Aburatsu, Japan), and Nelson (New Zealand).More news:  Flights cancelled as British Airways hit by computer problemFor its part, Seven Seas Navigator will ply Northern European waters in June and July 2019 and make maiden port calls on Cherbourg (France), Fishguard (Wales), Galway (Ireland), Kollafjord (Faroe Islands), Patreksfjordur and Husavik (Iceland), and Molde (Norway). The ship will sail Bermuda, Canada and New England itineraries from August through October 2019, and then reposition to sail Australia, New Zealand and South Pacific itineraries through March 2020. While in the South Pacific, Isle of Pines (New Caledonia), Phllip Island (Australia), and Adamstown (Pitcairn Islands) will also be maiden ports of call.On select Seven Seas Voyager and Seven Seas Navigator sailings in Asia and the South Pacific, guests in all suite categories enjoy a free three-night, pre- or post-cruise land program to delve deeper into the cultures of destinations such as Shanghai, Hong Kong, Singapore, Bangkok, Bali, Sydney, New Zealand, and Dubai and the Emirates.
