The best strategy for this environment is to have both episodic and semantic\r\nmemory systems. See the paper for more information.\r\n\r\n## Prerequisites\r\n\r\n1. A unix or unix-like x86 machine\r\n1. python 3.10 or higher.\r\n1. Running in a virtual environment (e.g., conda, virtualenv, etc.) is highly recommended so that you don't mess up with the system python.\r\n1. This env is added to the PyPI server. Just run: `pip install room-env`\r\n\r\n## Data collection\r\n\r\nData is collected from querying ConceptNet APIs. For simplicity, we only collect triples\r\nwhose format is (`head`, `atlocation`, `tail`). Here `head` is one of the 80 MS COCO\r\ndataset categories. This was kept in mind so that later on we can use images as well.\r\n\r\nIf you want to collect the data manually, then run below:\r\n\r\n```\r\npython collect_data.py\r\n```\r\n\r\n## How does this environment work?\r\n\r\nThe Gymnasium-compatible Room environment is one big room with\r\n_N__people_ number of people who can freely move\r\naround. Each of them selects one object, among\r\n_N__objects_, and places it in one of the\r\n_N__locations_ locations.\r\n_N__agents_ number of agent(s) are also in this\r\nroom. They can only observe one human placing an object, one at a time;\r\n**x**(_t_). At the same time, they are given one question\r\nabout the location of an object; **q**(_t_).\r\n**x**(_t_) is given as a quadruple,\r\n(**h**(_t_),**r**(_t_),**t**(_t_),_t_),\r\nFor example, `` accounts\r\nfor an observation where an agent sees James placing his laptop on his\r\ndesk at *t* = 42. **q**(_t_) is given as a double,\r\n(**h**,**r**). For example, `` is asking where\r\nKaren’s cat is located. If the agent answers the question correctly, it\r\ngets a reward of + 1, and if not, it gets 0.\r\n\r\nThe reason why the observations and questions are given as\r\nRDF-triple-like format is two folds. One is that this structured format\r\nis easily readable / writable by both humans and machines. Second is\r\nthat we can use existing knowledge graphs, such as ConceptNet .\r\n\r\nTo simplify the environment, the agents themselves are not actually\r\nmoving, but the room is continuously changing. There are several random\r\nfactors in this environment to be considered:\r\n\r\n1. With the chance of _p_commonsense,\r\n a human places an object in a commonsense location (e.g., a laptop\r\n on a desk). The commonsense knowledge we use is from ConceptNet.\r\n With the chance of\r\n 1 − *p*_commonsense_, an object is\r\n placed at a non-commonsense random location (e.g., a laptop on the\r\n tree).\r\n\r\n1. With the chance of\r\n _p__new_\\__location_, a human changes\r\n object location.\r\n\r\n1. With the chance of _p__new_\\__object_, a\r\n human changes his/her object to another one.\r\n\r\n1. With the chance of\r\n _p__switch_\\__person_, two people\r\n switch their locations. This is done to mimic an agent moving around\r\n the room.\r\n\r\nAll of the four probabilities account for the Bernoulli distributions.\r\n\r\nConsider there is only one agent. Then this is a POMDP, where _S__t_ = (**x**(_t_), **q**(_t_)), _A__t_ = (do something with **x**(_t_), answer **q**(_t_)), and _R__t_ ∈ *{0, 1}*.\r\n\r\nCurrently there is no RL trained for this. We only have some heuristics. Take a look at the paper for more details.\r\n\r\n## RoomEnv-v0\r\n\r\n```python\r\nimport gymnasium as gym\r\n\r\nenv = gym.make(\"room_env:RoomEnv-v0\")\r\n(observation, question), info = env.reset()\r\nrewards = 0\r\n\r\nwhile True:\r\n (observation, question), reward, done, truncated, info = env.step(\"This is my answer!\")\r\n rewards += reward\r\n if done:\r\n break\r\n\r\nprint(rewards)\r\n```\r\n\r\nEvery time when an agent takes an action, the environment will give you an observation\r\nand a question to answer. You can try directly answering the question,\r\nsuch as `env.step(\"This is my answer!\")`, but a better strategy is to keep the\r\nobservations in memory systems and take advantage of the current observation and the\r\nhistory of them in the memory systems.\r\n\r\nTake a look at [this repo](https://github.com/humemai/humemai) for an actual\r\ninteraction with this environment to learn a policy.\r\n\r\n## Contributing\r\n\r\nContributions are what make the open source community such an amazing place to be learn,\r\ninspire, and create.
