The Classification algorithm is a Supervised Learning technique that is used to identify the category of new observations on the basis of training data. In Classification, a program learns from the given dataset or observations and then classifies new observation into a number of classes or groups. Such as, Yes or No, 0 or 1, Spam or Not Spam ...

We want our classifier to output values between 0 and 1. When using linear regression we did h θ(x) = ( θT x) For classification hypothesis representation we do h θ(x) = g ((θT x)) Where we define g (z) z is a real number. g (z) = 1/ (1 + e-z) This is the sigmoid function, or the logistic function.

The coefficient estimates for Ordinary Least Squares rely on the independence of the features. When features are correlated and the columns of the design matrix \(X\) have an approximately linear dependence, the design matrix becomes close to singular and as a result, the least-squares estimate becomes highly sensitive to random errors in the observed target, producing a large variance.

Suppose, we want to make a spam filter which will filter spams from our email list automatically. So, for every email, we’re going to feed it to a classifier and the classifier will say if this is a spam or maybe we want to visit a restaurant for a specific food e.g. sushi but before visiting the restaurant we want to make sure that the sushi there is good. So, what we want to do is to check the review of others visiting this restaurant about sushi and see if it is positive. It is actually very difficult to manually check all the reviews. Instead, what we can do is to feed these reviews to a classifier and it is going to say, is this a positive sentiment or negative sentiment and then watching the number of positive sentiment and the negative sentiment we will decide whether the sushi there is good to go or not. See full list on medium.com A linear classifier will take some quantity x as input which in our case will be emails or reviews and is going to make a prediction ŷ that says is this a positive statement which means is this a no spam or a positive review in which case ŷ = +1 or is this a negative statement which implies it is a spam or a negative review in which case ŷ = -1. We will use restaurant review classifier for the rest fo the tutorial as our use case. A linear classifier does a little bit more associating every word for weight or coefficient which says how positively or negatively influential this word is for a review. For example, Here good and delicious have a coefficient of 1.0 and 1.5 respectively. Wonderful is very positive and has a coefficient of 2.7. On the negative side, bad and terrific might have a coefficient of -1 and -2.1 respectively. But awful is just awful, so -3.3. There are also some words that are not that relevant to the sentiment of the review, might have 0 coefficient. Now how wil... See full list on medium.com The decision boundary is a boundary between positive and negative predictions. Let’s say that we have taken our data and trained our linear classifier and every word has zero weight except for two of them. Awesome has weight 1.0 and awful has weight -1.5. That means that the score of any sentence is 1.0 times the number of the word awesome minus 1.5 times the number of times the word awful shows up. We can plot that into a graph which depends on every sentence the number of awesome and the number of awful. So for example, for a sentence, We’re going to plot that into space where we’re going to have two awesome and one awful. So it gets plotted in the (2,1) point. And then for every sentence that we might have in our training data set say, three awful and one awesome, three awesome and no awful and so on we will have different points and if we plot the dataset we find The classifier that we’ve trained with the coefficients 1.0 and -1.5 will have a decision boundary that corresponds t... See full list on medium.com in our previous example that we had with just two features with no zero coefficients, awesome and awful and we have calculated the score as where w₀ was 0 in our example. Now suppose that we had a third feature with no zero coefficient. Let’s say that the word great. So the score function then will be So, the general form of our linear classifier model will be : where Theses notations that we’ve used so far are without features associated with it. So we’re going to have these functions hᵢ where i is 1 through D. They’ve defined some features we might extract from the data and we are going to encode the constant function that is h₀. So the more generically our model will be looked like: where So this is our generic linear classifier model with multiple features. Linear classifiers are a pretty abstract concept. Logistic regression is a specific case of that, where we use what’s called the logistic function to squeeze minus infinity to plus infinity into the interval (0, 1) so we can...
