space then we look at a different data point so we look at this data point right here another data point what's the linear function around this one is sort of like whoops T is like that and then around this one is like this okay so this is one function now let's look at a different function right here so L X and we'll look at this function the linear function okay so for some reason this is like this and if we consider two data points their linearization is very similar now imagine that these two have been produced by the same sort of neural
