Ch 16. Visual recognition models
Successful models based on deep convolutional neural networks (CNNs) but early models required supervised learning and very data dense input
More modern models are data lean (representing objects with the smallest most efficient means) and use unsupervised training methods. They are very good

AUTISM
10% are savant
Stephen Wiltshire - draws scenes after a single view (helicopter trip over tokyo, rome, Manhattan etc)
NOT CAUSED BY VACCINES
andrew wakefield
pub (retracted) on “autistic enterocolitis”
12 patients,
- some currently suing MMR mfr
- Their lawyer paid wakefield 400,000lbs
- Wakefield had applied for a rival mmr patent
Lost his license

SCHIZOPHRENIA
Pos sx (intrusive thoughts), neg sx -
Alogia, anhedonia, asociality, affective flattening, avolition
Cognitive sx - diff with thinking , learning, memory and decision making - esp executive functioning
Cause unk; biological and genetic; eg adoptive child of schiz is 6-10x more likely to develop schiz the general pop; twins have hi concord (even if reared apart)
Inc dopamine, glutamate (NMDA)

Ch 19
OCD (howard hughes) - an amount of doubt about current state is usually offset by sense data (my certainty the light is off), pts with OCD are overwhelmed with doubt and need pathologic amounts of sensory data, even tho the actions often doesn’t make sense
