Study Notes
Recurrent Neural Networks in Automobility
- Recurrent neural networks are used in automobility for tasks such as driver activity anticipation and end-to-end driving models.
- In driver activity anticipation, multiple LSTM networks are used, one for each sensor (camera, GPS, vehicle dynamics, etc.), and sensor fusion is performed on hidden states.
- Loss function is designed with increased loss in late predictions.
- Comparisons are made with other works and different modifications.
Deep Steering
- Deep steering involves learning an end-to-end driving model from spatial and temporal visual cues.
- The model consists of a "feature extraction sub-network" and a "steering-prediction sub-network".
Recurrent Neural Networks
- Recurrent neural networks are used for sequential data, where information is revealed only by looking at a sequence of data.
- Fully connected models can be used for single time-step updates.
- Hidden states can represent recommended actions (e.g., breaking, accelerating, changing lane) at a given time step.
Notation
- Subscripts are used to define discrete time steps in a sequence.
