This problem set is organized around simulating a neuron\'s response to an input stimulus, then recovering the way that the neuron encodes the stimulus. 1) Generate stimulus data. Create 100 seconds of time varying random signal sampled at 500Hz th

Why is vector addition commutative, geometrically? Describe what you are doing when you \"find\" a point in Cartesian space in terms of adding vector projections onto the standard basis. Remember that a vector\'s representation in a given basis specif
