China - The unchanged culture of China allowed there to be a sense of patriotism, and unified the country. Wanted to be superior to the other countries, and to do this they remained self-sufficient. They also wanted to focus on their own security, since they were being attacked by the Manchus. Very worried about invasion. To achieve this, China built a wall. Show
Japan - Jesuits are trying to convert others to Christianity, and create a Catholic empire. In 1615 the Japanese drove the Jesuits from Japan. Began closed, or locked country policy to remain away from foreign influence and culture. Remained closed for over 200 years. The policy gave the Japanese 250 years of peace. To achieve this, they closed off their ports except for one. Only trades with the Chinese and Dutch. They are an island. In Japan, they remained isolated to save their culture and keep out foreign influence. In China, they remained isolated to feel superior and show off their wealth. Although there is no war, disease, or self-sufficient economy, the risk of having no allies is too great. They would also be cut off from new inventions, ideas, medicine, crops, and discoveries.

Terms in this set (20)Exploration thing that separates other machine learning topics from RL The more data we have the more confident we are to believe that data. True. Confidence based exploration To obtain alot of reward, an RL agent must prefer actions that it has tried in past and found to effective in producing reward. But to discover such actions it has to try actions that it has not selected before. The agent has to exploit what it has already experience , but it also has to True On a stochastic task, each action must be tried many times in order to gain a reliable estimate of its expected reward True Transitions bandits vs deterministic MDPs vs Stochastics MDPs bandits - don't have any state transitions at all but do have stochasticity K-Armed Bandits - k different arm bandits (slot machine) Minimum confidence is going to get you better estimates. While Max likelihood is going to get you more reward True Metrics for Bandits 1.
Maximize expected reward over finite horizon Can be combined If we have an algorithm that gets within epsilon per time step of optimal than find best. Hoeffding - how many number of samples we need to accurately learn the value of arm Exploring deterministic MDPs - explore randomly RMAX algorithm and what is the RMAX analysis 1. - Once all edges are know, no more mistakes : because solves MDP so every action is optimal 2. Stop visiting unknown states 3. Number of transitions to unknown state action pair is bounder by number of states Lower bound for algorithm is O(n^2 k) True General Stochastic MDPs - want to do efficient algorithm : Explore or exploit lemma - if all transitions are either accurately estimated or unknown, optimal policy is either near optimal or an unknown state is reached quickly Summary Bandits bandits which is all about stocasticity and randomness - lets us deal with stochastic decision making Hoffding bound tells us how certain we really are so that we know when we are certain enough True RMax works with Deterministic MDPs -optimism in the face of uncertainty Combined the 2 : use the bandit idea to estimate(noisy parameters) Transition probability and use RMax idea to make sure visited things enough to get accurate estimates True - stochastic + sequential KWIK learning - way we can distinguish in bandits from known and known can be generalized to KWIK learning - so if you can distinguish between known and unknown it can associate optimism with the unknown and it makes guaranteers on how efficiently near-optimal behavior can be learned - KWIK is a learning framework that try to generalize beyond tabluar MDPs to able to generalize between transition probablities between different parts of MDP Rmax setting c parameters Rmax in practice is very effective algorithm : makes good use of the data Other sets by this creatorCCC8 terms casanas10 Game Theory 39 terms casanas10 Game Theory Reloaded23 terms casanas10 Options12 terms casanas10 Verified questions

engineering The fan blows air at $6000\ \mathrm{ft}^3 / \mathrm{min}$. If the fan has a weight of $40\ \mathrm{lb}$ and a center of gravity at $G$, find the smallest diameter $d$ of its base so that it will not tip over. Assume the airstream through the fan has a diameter of $2\ \mathrm{ft}$. The specific weight of the air is $\gamma_a=0.076\ \mathrm{lb} / \mathrm{ft}^3$. Verified answer
