A neural network (Artificial Neural Network) is a mathematical model that mimics the structure and functioning of biological neural networks to solve various tasks such as classification, regression, forecasting, and generation. Neural networks are based on artificial neurons that are combined into graph structures and transmit signals to each other through connection weights. Through the learning process, during which the weights and offsets between neurons are optimized, neural networks become capable of detecting patterns and dependencies in the input data. Neural networks are actively used in such fields as computer vision, machine translation, speech recognition, etc.
What is an ARTIFICIAL NEURAL NETWORK – concept and definition in simple words.
In simple terms, a neural network is a computer system that tries to reproduce the work of the human brain, namely, how we perceive information and learn.
Imagine that your brain is a large network of connected “houses” (neurons) that transmit signals to each other. A neural network works on a similar principle: it consists of artificial neurons that are connected to each other and transmit information. These neurons can learn and adapt to become better at tasks such as image recognition, text translation, or weather forecasting. In other words:
A neural network (Artificial Neural Network) is a computer system that learns and improves in an effort to become more like the human brain in solving various tasks.
Basic structure and components of an artificial neural network.
The structure of a neural network consists of three main types of layers: input layer, hidden layers, and output layer.
A layer in a neural network is a group of neurons that work together and perform a specific function in the network. Imagine a neural network as a multi-story building where each floor contains rooms (neurons). The layers are connected to each other like stairs between floors. Each layer has its own role in the information processing process.
There are three main types of layers in an artificial neural network:
- Input layer: This is the “ground floor” of the house where we start. The input layer takes in data from the outside, such as images or text, and passes it on to the next layers. The input layer does not change the data, but only serves as an entry point for it.
- Hidden layers: These are the “middle floors” of the house. Hidden layers provide input data processing and information transfer between layers. They are called “hidden” because their results are not directly reflected in the network output. The number of hidden layers and the neurons in them can vary depending on the complexity of the problem and the architecture of the network.
- The output layer: This is the “top floor” of the house. The output layer forms the result that the neural network predicts based on the input data. The result can be a classification, a numerical value, or other information, depending on the type of task.
Thus, layers in a neural network are groups of neurons that work together and are responsible for different stages of information processing. They provide the neural network with the ability to adapt to different tasks.
All neurons in the layers are connected to each other through connection weights. Weights play an important role in training a neural network because they determine the strength of influence of one neuron on another. During training, the weights are optimized to minimize the network’s prediction error.
In addition to the connection weights, each neuron has a so-called bias, which allows you to adjust the activation of the neuron regardless of the input signal. The bias helps the neural network to adapt to different data more easily and perform more flexible transformations on the input data.
Another key component of a neural network is the activation function. It is applied to each neuron in the hidden and output layers to determine its activity based on the sum of the input signals multiplied by the appropriate weights and the addition of an offset. The activation function can be linear or non-linear, depending on the type of problem and the network architecture. Some of the most popular activation functions include sigmoid, hyperbolic tangent, ReLU (Rectified Linear Unit), and Softmax.
Training a neural network consists of optimizing the connection weights and biases based on a training data set. For this purpose, the method of backpropagation based on gradient descent is usually used. The training process can take a long time, depending on the size of the dataset, the network architecture, and the complexity of the problem.
Thus, the basic structure and components of a neural network include input, hidden, and output layers, neurons with connection weights and biases, and activation functions. Together, they help the neural network adapt to the input data and solve complex problems. Understanding these components and their interaction will help beginners to better understand the basics of neural networks and their applications.
Differences between biological and artificial neural networks.
Biological neural networks consist of biological cells – neurons that transmit impulses through synaptic connections. On the contrary, neural networks are based on mathematical models and computer algorithms, imitating the functioning of a biological network. However, artificial neural networks have a less complex structure and limited learning capacity compared to their biological counterparts. At the same time, neural networks have demonstrated impressive results in various fields of science and technology, including computer vision, machine translation, speech recognition, and autonomous driving.
One of the key differences between biological and artificial neural networks is the speed of signal transmission and learning. Biological neural networks can transmit impulses at speeds of up to 120 meters per second, while artificial networks transmit information at the speed of modern computer processors. Also, artificial neural networks learn much faster than biological ones due to the ability to use parallel algorithms and optimization of computations.
At the same time, biological neural networks have a much larger number of neurons and connections, which give them an advantage in analyzing complex situations and developing adaptive strategies. Artificial neural networks, despite their progress, cannot yet fully reproduce all the functions of the human brain.
The role of neural networks in problem-solving.
Neural networks play an important role in problem-solving because they can learn and adapt to different types of data and solve complex problems. Their main goal is to find patterns in data and apply this knowledge to predict or classify new data.
Types of tasks performed by neural networks.
Neural networks can perform different types of tasks, depending on the network architecture and training data. The main types of tasks include:
- Classification: Determining which category an object or event belongs to based on its characteristics.
- Regression: Predicting a numerical value based on input data.
- Text generation: The creation of text from training data, typically used to automatically create descriptions, articles, or answers to questions.
- Image processing: Recognizing objects, text, or faces in images.
Application of neural networks in various industries.
Neural networks are widely used in various industries and areas of life, such as
- Medicine: Diagnosing diseases, analyzing medical images, predicting the effectiveness of treatment.

The intricacies of neural network training: an introduction to the concept of training.
Training a neural network is a process during which the network learns to adapt and recognize patterns in the data provided to it. This process helps the neural network to provide correct conclusions and predictions based on new data that was not used during training.
The process of setting weights and shifts.
The basis of neural network training is setting up weights (connections between neurons) and biases (thresholds of neuronal activation). During the training process, the neural network constantly adjusts weights and biases to minimize the error between the network’s predictions and actual results.
The role of learning rate and optimization algorithms.
The learning rate and optimization algorithms play an important role in the neural network training process. The learning rate determines the level of change in weights and shifts during each iteration of the training process. Too high a learning rate can lead to missing the optimal values, while a low learning rate can result in a slow training process.
Optimization algorithms, such as gradient descent or adaptive methods (e.g., Adam), are used to find the optimal weights and biases that minimize the loss function (the error between predictions and actual data).
Knowing the intricacies of neural network training makes it possible to create efficient and accurate models for various tasks and applications.
Practical application of neural networks.
To use neural networks for solving specific tasks, you first need to prepare a data set for training. This dataset can contain examples that reflect the relationship between the input data and the desired outputs. Usually, the data is divided into training, validation, and test sets to control the training process and evaluate its results.
When training a neural network, examples from the training dataset are demonstrated, and optimization algorithms adjust weights and biases based on the learning rate. The validation dataset is used to assess the quality of the model during training, allowing to detect over- or under-training.
Once the training process is complete, the neural network is ready to be used in real-world situations, where it can be used for outcome prediction, classification, pattern recognition, speech processing, and other tasks.
Thus, training a neural network involves a number of important aspects, such as setting weights and biases, learning speed, optimization algorithms, and working with data sets. Understanding these intricacies will help you create and apply effective neural networks to solve complex problems and increase productivity in various industries.

Deep learning: Define deep learning and how it relates to neural networks.
Deep learning is the development and extension of classical neural networks that provides the ability to recognize, analyze, and classify more complex patterns and hierarchies. Deep neural networks consist of many layers of neurons that interact with each other, transmitting information from inputs to outputs.
Advantages and limitations of deep learning.
The advantages of deep learning are its high accuracy and ability to process large amounts of data. Deep neural networks demonstrate extraordinary efficiency in pattern recognition, speech processing, and other tasks that classical algorithms have difficulty solving. Deep learning has enabled breakthroughs in areas such as computer vision, autonomous cars, and machine translation.
However, deep learning has its limitations.
- First, it requires huge amounts of data and computing power to train and optimize models.
- Secondly, deep neural networks can be difficult to interpret and explain, making it difficult to understand how they make decisions.
- Third, there may be a problem of overtraining, when the model is too good at “remembering” training data but not good at generalizing new information.
Despite these limitations, deep learning continues to evolve and make significant changes in many fields of science and technology. Researchers are actively working on improving deep learning algorithms, reducing computing power requirements, and improving the clarity and interpretation of models.
One of these trends is the use of transfer learning techniques, which allow using the knowledge gained from training one model to quickly train other models in similar tasks. This can contribute to the efficient use of resources and increase the overall performance of deep learning.
New neural network architectures are also emerging that attempt to recreate more accurate models of the human brain and its functioning, such as capsule networks and spiking neural networks. They can lead to even more powerful and efficient deep learning systems.
Working with neural networks: a practical guide.
The process of working with neural networks begins with choosing the appropriate architecture that is best suited for solving a particular problem. The choice depends on the type of data, the amount of data, and the complexity of the problem to be solved. Different neural network architectures, such as convolutional (CNN), recurrent (RNN), and deep (DNN), offer different capabilities for different application scenarios.
What are the architectures of artificial neural networks?
There are several basic neural network architectures, each designed for different types of tasks and applications. Here are some of them:
- Feedforward Neural Networks (FNN): This is the simplest neural network architecture in which information is transmitted in one direction, from input to output, through different layers. They have no loops or feedbacks and consist of one or more hidden layers.
- Convolutional Neural Networks (CNN): Convolutional neural networks are designed specifically to work with data that has a spatial structure, such as images. They use convolutional layers to automatically detect image features, instead of manually engineering features.
- Recurrent Neural Networks (RNN): Recurrent neural networks are designed to work with sequential data, such as text or time series. They have feedback loops that allow them to remember information from previous steps. This allows them to work better with data where context is important.
- Long Short-Term Memory (LSTM): LSTM is a type of recurrent neural network that solves the problem of gradient decay that occurs when training traditional RNNs. LSTM has a special structure of nodes that allow the model to “remember” or “forget” information over a long period of time.
- Convolutional autoencoder networks (CAE): Autoencoders are neural networks that learn to encode input data into a compact representation and then reconstruct the output data from that representation. Convolutional autoencoders use convolutional layers to deal with spatial data such as images and are commonly used for feature detection or image reconstruction.
- Generative Adversarial Networks (GAN): Generative adversarial networks consist of two separate neural networks that work together: a generator that creates synthetic data and a discriminator that learns to distinguish between real and synthetic data. GANs are commonly used to generate images, texts, and other types of data.
- Capsule Networks (CapsNet): Capsule networks are a type of convolutional neural networks that use special capsule layers to store information about the spatial relationships between objects in an image. They can better understand hierarchical data structures and usually perform better than traditional convolutional networks for object recognition tasks.
- Attention Networks: Attention networks are an architecture that allows models to pay more attention to important parts of the input data. The attention mechanism is usually used in combination with recurrent or transformer networks, especially in natural language processing tasks such as machine translation and text generation.
- Graph Neural Networks (GNN): GNNs are a neural network architecture that works with graphical data structures. They are able to process relationships between objects and aggregate information from neighboring nodes. GNNs are often used in recommender systems, social network analysis, and chemical modeling.
- Spiking neural networks are a class of networks that attempt to more accurately model the dynamics of spiking neurons in the biological brain. They do this by introducing a temporal component into the activation functions of neurons.
The importance of data preprocessing and feature engineering.
Data preprocessing and feature engineering are critical steps in working with neural networks. They ensure that the input data is cleaned and converted into a format that can be easily processed by the neural network. Typically, data preprocessing includes normalization, filling in missing values, and removing noise. Feature engineering involves selecting the most important features and creating new features that can improve model performance.
Best practices for training and tuning neural networks.
When training a neural network, you should follow a few basic principles. First, divide the data into training, validation, and test sets to be able to evaluate the model’s performance and avoid overfitting. Second, use optimization techniques such as gradient descent or adaptive methods to help find the optimal model parameters. Third, when tuning hyperparameters such as learning rate, number of layers, or number of neurons, use methods such as cross-validation or grid search to find the optimal values for your model.
It is also important to monitor the neural network training process using tools such as loss function visualization and accuracy metrics. This allows you to monitor the success of the training and identify problems with overtraining or undertraining. If necessary, you can stop training or change hyperparameters to improve results.
Taking into account all these aspects of working with neural networks, you will be able to build effective and reliable models that will help solve complex problems and bring valuable results in various applications. With hands-on experience and the application of best practices in neural network training and tuning, you will be able to improve your skills and make a significant contribution to the development of artificial intelligence.
