Learning patterns

Overview[ edit ] Pattern recognition is generally categorized according to the type of learning procedure used to generate the output value. Supervised learning assumes that a set of training data the training set has been provided, consisting of a set of instances that have been properly labeled by hand with the correct output. Training patterns are the goals of the training process and not to be confused with the training set. Perform as well as possible on the training data, and generalize as well as possible to new data usually, this means being as simple as possible, for some technical definition of "simple", in accordance with Occam's Razordiscussed below.

Learning patterns

Indeed, only a small fraction of professionals really know what it stands for. And there is a serious reason for it — this field is rather technical and difficult to explain to a layman. However, we would like to bridge this gap and explain a bit about what machine learning ML is and how it can be used in our everyday life or business.

So what is this mysterious ML? Machine learning can refer to: Learning patterns, this Learning patterns is quite a broad one, so we can quote another more specific description stating that ML deals with systems that can learn from data. ML works with data and processes it to discover patterns that can be later used to analyse new data.

For example, if we are talking about text it should be represented through the words it contains or some other characteristics such as length of the text, number of emotional words etc. Now let us explain in simple words the kind of problems that are dealt with by each category.

This is easier to explain using an example. Let us imagine that we want to teach a computer to distinguish pictures of cats and dogs. Labelling is usually done by human annotators to ensure a high quality of data.


As the reader can guess from the name, unsupervised ML means that we deprive a learning algorithm of the labels we used in supervised learning. We just provide ML with a large amount of data and characteristic of each observation single piece of data.

Learning patterns

As an example, imagine your friends were not very helpful and forgot to label the images of cats and dogs that they have sent. However, you still want to split this data into 2 categories.

You can employ unsupervised ML in this case a technique called clustering to separate your images in two groups based on some inherent features characteristics of the pictures. A graph below presents a simplified workflow of a typical ML task it is a general graph that shows the processing both in terms of supervised and unsupervised ML.

Typical Machine Learning workflow Another well-known class of ML problems is called reinforcement learning. This class of ML problems can be easily illustrated by an example of learning to play chess. As input to this problem ML receives information about whether a game played was won or lost.

So ML does not have every move in the game labelled as successful or not, but only has the result of the whole game. What do we need to use ML? Given the fact that ML relies on data, the most important requirement of using ML is having the data you can use to train a ML model.

The amount of data needed depends on what you are looking for and how complex your problem is. However, collecting more data is always a good idea. One should also keep in mind that this data that you want to train your ML on should be similar to the one you want to make predictions on later.

For example, looking at reviews of books and learning to predict opinions of people positive or negative about some books, may yield not really great results when applied to reviews of mobile phones or laptops. Another requirement involves your ability to formulate the question you want to pose to an ML expert, you need to know what you want to get as a result.Fun children's learning activities, including printable templates, for preschool, kindergarten and elementary school kids.

Some prefer greater amounts of control while others are happy going with the flow. As a student, you will be encouraged to tailor the online experience to fit your learning patterns.
