How Does Artificial Intelligence Learn Through Machine Learning Algorithms?

Artificial intelligence (AI) and machine learning (ML) solutions have made a significant impact on the enterprise sector, revolutionizing operations through smart automation. ML algorithms, with their ability to optimize processes, have become integral to numerous online services.

Enterprises are gradually adopting AI solutions as they recognize the benefits offered by this technology. However, there are challenges associated with its adoption. In the realm of business intelligence, AI is primarily employed to derive insights from vast amounts of user data, which inform key decision-making. However, the inner workings of AI in generating these insights remain unknown, requiring companies to trust the algorithms when making critical business decisions. This is especially true for machine learning algorithms.

Nevertheless, gaining a fundamental understanding of how machine learning operates can demystify the concept. Let’s delve into the workings of machine learning algorithms and how AI enhances itself through ML.

What Are Machine Learning Algorithms?

Machine learning algorithms are computer programs that learn from data. They leverage the information provided to them to improve their performance in a given task. For instance, consider a machine learning algorithm designed to identify cats in images. Initially, the algorithm is trained using pictures of cats. By demonstrating what a cat looks like and rewarding correct guesses, the algorithm gradually learns to recognize the features indicative of a cat.

Once the algorithm has been trained to achieve a high level of accuracy, it can be deployed as a solution to identify cats in images. However, the learning process does not stop there. Any new input the algorithm processes further enhances its ability to accurately detect cats in images. ML algorithms employ various cognitive methods and shortcuts to identify the characteristics of a cat.

These algorithms utilize different strategies to determine what a cat looks like. Consequently, we question: How exactly do machine learning algorithms work? A closer examination of the fundamental concepts of artificial intelligence provides a clearer answer.

Artificial intelligence serves as an umbrella term encompassing computers that exhibit any form of human cognition. It describes the manner in which computers imitate human intelligence. Even within this definition of ‘intelligence,’ AI functions differently from human thinking.

Today, AI manifests as computer programs written in languages such as Python and Java. These complex programs attempt to replicate human cognitive processes. Among them, certain programs referred to as machine learning algorithms can accurately simulate the cognitive process of learning.

These ML algorithms are not easily explainable, as only the program itself possesses knowledge of the specific cognitive shortcuts used to find the optimal solution. The algorithm takes into account all the variables it encountered during training and determines the best combination of these variables to solve a problem. Through a process of trial and error, the machine “learns” this unique combination of variables. Machine learning encompasses various types, depending on the training methodology applied.

Thus, it becomes apparent how machine learning algorithms can be beneficial in scenarios involving abundant data. The more data an ML algorithm ingests, the more effective it becomes at solving the problem at hand. The program continues to improve and refine itself with each problem it solves.

Creating a Machine Learning Algorithm

To enable programs to learn autonomously, a range of approaches can be employed. Typically, the creation of a machine learning algorithm begins with defining the problem. This involves identifying potential solutions, establishing boundaries, and formulating a concise problem statement.

Once the problem has been defined, the data is prepared by removing any inconsistencies or errors. Every machine learning problem comes with a dataset that requires analysis to uncover the solution. Within this data lies the solution or a pathway to it, which can be discovered through ML analysis.

After cleaning and preprocessing the data to make it accessible to the machine learning algorithm, the algorithm’s construction begins. The program must be structured in a way that allows it to solve the problem, often emulating human cognitive methods.

In the case of the cat analysis algorithm example, the program is taught to examine shifts in color within an image and detect changes. Abrupt color transitions from pixel to pixel may indicate the cat’s outline. By utilizing this method, the algorithm can identify the edges of the cat in the picture. ML algorithms undergo fine-tuning using such techniques until they can find the optimal solution within a limited dataset.

Once this step is completed, an objective function is introduced. The objective function enhances the algorithm’s efficiency in solving the problem. While the cat-detecting algorithm’s objective is to identify a cat, the objective function could focus on achieving the solution in minimal time. By incorporating an objective function, the algorithm can be specifically tuned to solve the problem faster or with greater accuracy.

The algorithm is trained using a sample dataset and the basic blueprint of what it needs to accomplish, all while considering the objective function. Multiple training methods can be employed to create machine learning algorithms, including supervised training, unsupervised training, and reinforcement learning. Let’s explore each of these methods further.

Types of Machine Learning Algorithms

Various training approaches exist, each yielding different levels of success and effectiveness for specific problem statements. Let’s examine the following types:

Supervised machine learning is the simplest method to train an ML algorithm, resulting in straightforward algorithms. Supervised ML learns from a small dataset called the training dataset, which is then applied to a larger dataset known as the problem dataset, ultimately producing a solution. The data provided to these machine learning algorithms is labeled and categorized, requiring significant human effort to annotate the data.

Unsupervised ML algorithms operate differently from supervised ones. The data given to unsupervised machine learning algorithms is neither labeled nor categorized. As a result, the ML algorithm is tasked with solving the problem with minimal manual training. These algorithms are provided with the dataset and left to their own devices, enabling them to identify hidden structures. Hidden structures represent meaningful patterns within unlabeled datasets, which the ML algorithm discovers to solve the problem statement.

Reinforcement learning (RL) algorithms represent a recent advancement in machine learning training methods. RL offers rewards to algorithms when they provide correct solutions and withdraws rewards for incorrect solutions. More effective and efficient solutions receive higher rewards, incentivizing the RL algorithm to optimize its learning process through trial and error. This results in a broader comprehension of the problem statement for the machine learning algorithm.

Distinguishing Artificial Intelligence from Machine Learning Algorithms

If a program functions similarly to the human brain, even without the ability to learn from new information, it falls under the category of AI.

For example, a program designed to play chess at a high level can be classified as AI. Like humans, it evaluates potential moves when a move is made. However, the program can compute all possible moves, whereas even the most skilled humans can only calculate a limited number of moves ahead.

Machine learning algorithms, unlike AI programs, have the ability to adapt to new information and changes in the problem statement. Take the example of a chess-playing ML algorithm. Initially, it has no knowledge of the game but learns through playing games and analyzing moves. With a clearly defined objective function, the algorithm iterates and improves over time, eventually surpassing human capabilities.

It’s important to understand that while machine learning algorithms fall under the broader umbrella of AI, not all AI systems rely on machine learning. AI encompasses programs that mimic or replicate certain aspects of human intelligence. On the other hand, machine learning algorithms refer to programs that can learn and improve by processing data.

There is a specialized category within AI known as deep learning algorithms, which exhibit characteristics of both machine learning and AI. Deep learning algorithms employ artificial neural networks that mimic the structure of the human brain. These algorithms can perform complex tasks and learn from data, but explaining their actions can be challenging.

Deep learning algorithms hold great potential for powerful AI systems, as they can handle more intricate tasks compared to traditional machine learning algorithms. They improve themselves by creating hidden structures within the data, similar to unsupervised machine learning algorithms. These structures are then processed through layers of the neural network to interpret the data. Fine-tuning these layers enhances the efficiency of deep learning algorithms.

Deep learning has found numerous real-world applications and is particularly effective in providing personalized recommendations to users. Additionally, deep learning algorithms can communicate with other AI programs, resembling human-like interactions.

In the tech community, it is widely recognized that AI and machine learning are distinct concepts. While machine learning algorithms enable self-improvement, the ultimate goal is to develop general artificial intelligence—a form of AI capable of independent thinking and functioning at a high level, similar to humans.
