for the agent that doesn't require a fully rendered image to convey.
- Use as few rays and tags as necessary to solve the problem in order to improve
learning stability and agent performance.
### Variable Length Observations
It is possible for agents to collect observations from a varying number of
GameObjects by using a `BufferSensor`.
You can add a `BufferSensor` to your Agent by adding a `BufferSensorComponent` to
its GameObject.
The `BufferSensor` can be useful in situations in which the Agent must pay
attention to a varying number of entities (for example, a varying number of
enemies or projectiles).
On the trainer side, the `BufferSensor`
is processed using an attention module. More information about attention
mechanisms can be found [here](https://arxiv.org/abs/1706.03762). Training or
doing inference with variable length observations can be slower than using
a flat vector observation. However, attention mechanisms enable solving
problems that require comparative reasoning between entities in a scene
such as our [Sorter environment](Learning-Environment-Examples.md#sorter).
Note that even though the `BufferSensor` can process a variable number of
entities, you still need to define a maximum number of entities. This is
because our network architecture requires to know what the shape of the
observations will be. If fewer entities are observed than the maximum, the
observation will be padded with zeros and the trainer will ignore
the padded observations. Note that attention layers are invariant to
the order of the entities, so there is no need to properly "order" the
entities before feeding them into the `BufferSensor`.
The the `BufferSensorComponent` Editor inspector have two arguments:
- `Observation Size` : This is how many floats each entities will be
represented with. This number is fixed and all entities must
have the same representation. For example, if the entities you want to
put into the `BufferSensor` have for relevant information position and
speed, then the `Observation Size` should be 6 floats.
- `Maximum Number of Entities` : This is the maximum number of entities
the `BufferSensor` will be able to collect.
To add an entity's observations to a `BufferSensorComponent`, you need
to call `BufferSensorComponent.AppendObservation()`
with a float array of size `Observation Size` as argument.
__Note__: Currently, the observations put into the `BufferSensor` are
not normalized, you will need to normalize your observations manually
between -1 and 1.
#### Variable Length Observation Summary & Best Practices
- Attach `BufferSensorComponent` to use.
- Call `BufferSensorComponent.AppendObservation()` to add the observations
of an entity to the `BufferSensor`.
- Normalize the entities observations before feeding them into the `BufferSensor`.
## Actions and Actuators

docs/Learning-Environment-Examples.md


- 37.6 for vector observations
- 34.2 for simple heuristic (pick a random valid move)
- 37.0 for greedy heuristic (pick the highest-scoring valid move)
## Sorter
![Sorter](images/sorter.png)
- Set-up: The Agent is in a circular room with numbered tiles. The values of the
tiles are random between 1 and 20. The tiles present in the room are randomized
at each episode. When the Agent visits a tile, it turns green.
- Goal: Visit all the tiles in ascending order.
- Agents: The environment contains a single Agent
- Agent Reward Function:
- -.0002 Existential penalty.
- +1 For visiting the right tile
- -1 For visiting the wrong tile
- BehaviorParameters:
- Vector Observations : 4 : 2 floats for Position and 2 floats for orientation
- Variable Length Observations : Between 1 and 20 entities (one for each tile)
each with 22 observations, the first 20 are one hot encoding of the value of the tile,
the 21st and 22nd represent the position of the tile relative to the Agent and the 23rd
is `1` if the tile was visited and `0` otherwise.
- Actions: 3 discrete branched actions corresponding to forward, backward,
sideways movement, as well as rotation.
- Float Properties: One
- num_tiles: The maximum number of tiles to sample.
- Default: 2
- Recommended Minimum: 1
- Recommended Maximum: 20
- Benchmark Mean Reward: Depends on the number of tiles.
