- 12 Types of Learning in mammalsAssociative Learning: Classical conditioning + Operant Conditioning
Non-Associative Learning: Habituation + Sensitization - 2Classical ConditioningPavlovs doge
- 3Operant ConditioningPositive reinforcement: favorable stimulus after behaviour
Negative reinforcement: removal of aversive stimulus after behaviour - 4HabituationDecrease response to repeated stimulus(Something is scary at first but then becomes normal)
- 5SensitizationAmplification of response to repeated stimuli(Becoming better at catching a ball)
- 6Hebbian learning, Hebbs ruleCells FIRE, cells WIRE
(cells that fire together strengthen synapses, cells that dont lose synapses) - 7Learning over different TimescalesDevelopmental, Behavioral, Evolutionary
- 8Developmentalleanring that naturally comes with development of an organism
- 9Behavioral LearningChange in behaviour
- 10EvolutionaryOver a long ass time, goes over many generations, basically evolution doing its job
- 11LTP/LTDLong Term Potentiation/Depression
- 12LTPEPSP ^, synapse strenghtening
- 13LTDIPSP ^, synapse weakening
- 14Associative LTPCooperativity, Associativity, Specificity
- 15CooperativityWorks when multiple inputs are simultaneosly active
- 16AssociativityWeak inputs are potentiated when co-occuring with stronger inputs
- 17SpecificityOnly stimulated synapse shows potentiation
- 18NMDA ReceptorProduces LTP but doesnt maintain it!
- 19LTP takes place in 3 synaptic sites in the hypocampusPerforant pathway, Mossy fiber pathway
Shaffer collateral pathway - 20Types of Machine LearningSupervise, Reinforced, Unsupervised
- 21SupervisedTaught by a teacher, Artificial Neural Networks (ANN)
- 22ReinforcedWith Rewards, a bit of help
- 23Unsupervised Learningall by itself, Principle Component Analysis (PCA), Content Addressable Memories (CAM)
- 24ANNLike the Perceptron(Too long for flashcards see notes)
- 25In the perceptron what is the paralell to the synapse strengthWeights
