Machine learning in addition to feature representations Input Input space Feature space Feature representation Learning algorithm pixel 1 “wheel” How is computer perception done Object detection Audio classification Helicopter control Learning representations Sensor Learning algorithm Feature Representation

Computer vision features SIFT Spin image HoG RIFT Textons GLOH Audio features ZCR Spectrogram MFCC Rolloff Flux Problems of h in addition to -tuned features 1. Needs expert knowledge 2. Time-consuming in addition to expensive 3. Does not generalize to other domains Computer vision is more than pictures Can we automatically learn good feature representations Key question: Can we automatically learn a good feature representation

Learning representations Sensor Learning algorithm Feature Representation Sensor representation in the brain [BrainPort; Martinez et al; Roe et al.] Human echolocation (sonar) Auditory cortex learns to see. Auditory Cortex Unsupervised feature learning Find a better way to represent images than pixels.

The goal of Unsupervised Feature Learning Tutorial outline Current methods. Sparse coding as long as feature learning. — Break — Advanced classification. Advanced concepts & deep learning.
