Testing hypothesis 2 : Are the tropics a museum?

Those are the only two values that Y could possibly take on, either in the training set or for new patients that may walk into my office or into the doctor's office in the future. So given h of x, we can therefore compute the probability that y is equal to zero as well. Concretely, because y must be either zero or one, we know that the probability of y equals zero, plus the probability of y equals one, must add up to one. This first equation looks a little bit more complicated but it's basically saying that probability of y equals zero for a particular patient with features x, and you know, given our parameter's theta, plus the probability of y equals one for that same patient which. And this is just saying that the probability of y equals zero plus the probability of y equals one must be equal to one. And we know this to be true because y has to be either zero or one.

So we may have a feature vector x, which is this x01 as always and then our one feature is the size debt of the tumor. Suppose i have a patient come in and, you know they have some tumor size and I feed their feature vector x into my hypothesis and suppose my hypothesis outputs the number.7. I'm going to interpret my hypothesis as follows. I'm going to say that this hypothesis is telling me that for a patient with features x, the probability that y equals one.7. In other words, i'm going to tell my patient that the tumor, sadly, has a 70 chance or.7 chance of being malignant. To write this out slightly more formally or to write this out in math, i'm going to interpret my hypothesis output as p of y equals 1, given X parametrized by theta. So, for those of you that are familiar with probability, this equation might make sense, if you're a little less familiar with probability, you know, here's how I read this expression, this is the probability that y is equals to one, plan given x instead. Given my patient has a particular tumor size represented by my features x, and this probability is parametrized by theta. So i'm basically going to count on my hypothesis to give me estimates of the probability that y is equal. Now since this is a classification task, we know that Y must be either zero or one, right?

Finally, given this hypothesis representation, what we need to do, as before, is fit the parameters theta to our data. So given a training set, we need to pick a value for the parameters theta and this hypothesis will then let us make predictions. We'll talk about a learning algorithm later for fitting the parameters theta. But first let's talk a bit paper about the interpretation of this model. Here's how I'm going to interpret the output of my hypothesis h. When my hypothesis outputs some number, i am going to treat that number as the estimated probability that y is equal to one on a new input example. Here is what I mean. Here is an example. Let's say we're using the tumor classification example.

Lastly, let me show you where the sigmoid function looks like. We're going to plot it on this figure here. The sigmoid function, g of z, also called the logistic function, looks like this. It starts off near zero and then rises until it processes.5 at the origin and then it flattens out again like. So that's what the sigmoid function looks like. And you notice that the sigmoid function, well, it asymptotes at one, and asymptotes at zero as z against the horizontal axis. As Z goes to minus infinity, g of z approaches zero and as g of z approaches infinity, g of z approaches 1, and so because g of z offers values that are between 0 and 1 we also have that h of X must.

When we were using linear regression, this was the form of a hypothesis, where h of x is theta transpose. For logistic regression, i'm going to modify this a little bit, and make the hypothesis g of theta transpose x, where i'm going to define the function g as follows: g of z if z is a real number is equal to one over one. This called the sigmoid function or the logistic function. And the term logistic function, that's what give rise to the name logistic progression. And, by the way, the terms sigmoid function and logistic function are basically synonyms and mean the same thing. So the two terms are basically interchangeable and either term can be used to refer to this function. And if we take these two equations, and put them together, then here's just an alternative way of writing out the form of my hypothesis. I'm saying that h of x is one over one plus E to the negative theta transpose x, and all i've done is i've taken the variable z, z here's a real number and plugged in theta transpose x, so i end up with, you.

In this video, i'd like to show you the hypothesis representation, that is, what is the function we're going to use to represent our hypothesis where we have a classification problem. Earlier, we said that we would like our classifier to output values that are between zero and one. So, we like to come up with a hypothesis that satisfies this property, that these predictions are maybe between zero and one.

His love for Hebrew and its grammar came from learning it from his father William Chomsky at a very young age. Before Chomsky, linguistic study focused mainly on performance (how people spoke). But after his arrival into the field of linguistics brain became an important guaranteed aspect in language study. 4, the first step of Chomsky getting into the field of language study started when he took up the concept of Platos problem or poverty of stimulus which means-when the input is so meager why is the output so large? This led him to discover the concept innateness hypothesis which says that humans are born with the ability of acquiring language. We have lad that helps in the acquisition process. Lad is Language Acquisition device situated in the left hemisphere of the brain. Universal Grammar- Chomsky is the founder of the opinion that every child is born with Universal grammar which helps the child to acquire the language.
