What is a algorithm in AI?

It is a searching algorithm that is used to find the shortest path between an initial and a final point. It is a handy algorithm that is often used for map traversal to find the shortest path to be taken. A* was initially designed as a graph traversal problem, to help build a robot that can find its own course.

An algorithm is a procedure used for solving a problem or performing a computation. Algorithms act as an exact list of instructions that conduct specified actions step by step in either hardware- or software-based routines. Algorithms are widely used throughout all areas of IT.

Below is the list of Top 10 commonly used Machine Learning (ML) Algorithms:

  • Linear regression.
  • Logistic regression.
  • Decision tree.
  • SVM algorithm.
  • Naive Bayes algorithm.
  • KNN algorithm.
  • K-means.
  • Random forest algorithm. More items.

Machine learning and artificial intelligence are both sets of algorithms, but differ depending on whether the data they receive is structured or unstructured. We hope this adds some clarity to terms that are all too often used interchangeably.

What are the 3 algorithms?
There are three basic constructs in an algorithm: Linear Sequence: is progression of tasks or statements that follow one after the other. Conditional: IF-THEN-ELSE is decision that is made between two course of actions. Loop: WHILE and FOR are sequences of statements that are repeated a number of times.

What is algorithm example?
Algorithms are all around us. Common examples include: the recipe for baking a cake, the method we use to solve a long division problem, the process of doing laundry, and the functionality of a search engine are all examples of an algorithm.

Are algorithms important for AI?
In both research areas, the use of algorithms in AI is the fundamental basis. They are used to analyze data, to gain insight and to subsequently make a prediction or create a determination with it. Instead of manually coding software with a specific instruction set, the machine is trained at Machine Learning.

The role of algorithms in AI, or artificial intelligence

Algorithms and AI or KI, artificial intelligence, are inseparable. In fact, algorithms form the basis of artificial intelligence. But what exactly is artificial intelligence and what role do algorithms play in this? As the name suggests, artificial intelligence creates an artifact that shows some form of intelligence. This brings great benefits for humanity but also has a downside. Because how much thinking do we want to give machines?

Algorithms and AI are inseparable

Before we can clarify the role of algorithms in artificial intelligence, the definition of an algorithm is needed first. An algorithm is a set of instructions that leads to an intended end goal from an established initial situation. In principle, an algorithm is therefore separate from a computer program, although computers are generally used for the execution of an algorithm. The intended end goal of an algorithm can be anything. The finite series of instructions are prepared in such a way that they can generally deal with eventualities that may occur during implementation. Often algorithms have repetitive steps, which is called iteration. They also generally require decisions, comparisons or logic to complete the intended task.

Comparison with cooking recipes

One and the same task can usually be solved with various instruction series. The difference lies in the amount of effort, space or time that the algorithm needs. This is called complexity. For example, you can compare an algorithm with a cooking recipe. Suppose you want to make a potato salad. With one recipe you must first cook the potato according to the instructions and according to the other recipe you must first peel the potato. In both recipes, however, these two steps are required for the correct execution of the intended end result, the intended potato salad.

Formal systems and the 'internal state'

This works in a similar way with an algorithm. It must correctly implement the intended end result and the algorithm itself must therefore be properly executed by the computer program. In formal systems, algorithms are essential for, among other things, the way in which a computer processes the information. A computer program is therefore a formal algorithm that gives the computer instructions which steps must be carried out in which order to reach the intended end goal. Information is therefore processed with algorithms. The data is read from the input device and then written to an output device. It can be saved here. This is also called the 'internal state'.

Machine Learning (ML)

Back to algorithms and AI. With artificial intelligence, algorithms can be developed for computers, among other things, to enable them to learn. Machine or automatic learning is a comprehensive field of research within AI and is referred to as Machine Learning (ML). Patterns are extracted from data. Today, these developments are gaining momentum because the cloud brings computing power in abundance. For example, a computer can translate texts, understand spoken word and also understand images. You will find Machine Learning in the self-driving car, among other things.

Analyzing data and data mining

Machine Learning is focused on analyzing data or statistical analysis. It is focused on implementation in programs or algorithmic complexity. In addition, it is related to so-called 'data mining'. Hereby relationships and patterns in large amounts of data are searched for in an automated way. In both research areas, the use of algorithms in AI is the fundamental basis. They are used to analyze data, to gain insight and to subsequently make a prediction or create a determination with it. Instead of manually coding software with a specific instruction set, the machine is trained at Machine Learning. This by using algorithms and large amounts of data that should offer the possibility to learn how to complete a task.

Neural networks and Deep Learning (DL)

A Neural network is used to discover patterns in data. In addition, the software simulates a structure that is similar to the neurons of our human brain. This structure can be made up of dozens or even hundreds of different layers. This is therefore called Deep Learning (DL). This neural network can be trained with examples that are classified by humans, but the network can also find patterns in data that are not controlled by humans. In addition, DL can be semi-controlled. DL is part of a wider family of methods for Machine Learning.

Deep Learning: controlled, uncontrolled and semi-controlled

In the case of controlled Deep Learning, AI algorithms provide examples of the input and related output. The learning aspect here is that based on these examples, the input properties determine the final output. Once the learning phase has been completed, algorithms can independently realize the correct output for new input. With uncontrolled Deep Learning, no examples are given of the desired output. The algorithms themselves then discover a structure in the input that is given. With semi-controlled Deep Learning this is in between both learning methods.
