Пожарът в самоковското село Говедарци остави без дом две семейства с малки деца, предава NOVA. В сряда пожар в самоковското село Говедарци изпепели няколко къщи и земеделски постройки.
Търсят се доброволци, които да се включват в разчистването, а местните молят за всякаква помощ и подкрепа за пострадалите, които на прага на зимата остават на улицата.
Тази сутрин на място отново имаше екип на пожарната, след като са се запалили дърва в двора.

Machine learning is a subset of artificial intelligence that focuses on creating systems that can automatically learn and improve from experience, without being explicitly programmed. It involves the development of algorithms and statistical models that enable computers to automatically analyze and interpret large amounts of data, and make predictions or decisions based on that analysis.
The process of machine learning typically involves the following steps:
1. Data collection: Gathering large amounts of relevant data on the subject at hand. This might involve collecting data from various sources, such as databases, sensors, or the internet.
2. Data preprocessing: Cleaning and organizing the collected data to ensure its quality and relevance for the specific task. This might involve removing irrelevant or duplicate data points, handling missing values, or transforming the data into a usable format.
3. Feature selection: Identifying the most informative features (or attributes) of the data that are most relevant to the task at hand. This might involve selecting a subset of the available features or creating new features based on domain knowledge.
4. Model selection: Choosing an appropriate machine learning algorithm (or model) that is best suited for the specific task. This might involve selecting from a variety of models, such as decision trees, support vector machines, or neural networks, based on factors like the type of problem, available data, and desired performance metrics.
5. Model training: Training the selected model using the prepared data. This involves providing the model with known input-output pairs (i.e., training examples) and allowing it to learn the underlying patterns and relationships in the data. The model adjusts its internal parameters to minimize the difference between its predicted outputs and the known outputs.
6. Model evaluation: Assessing the performance of the trained model on unseen data. This involves feeding the model with a separate set of input-output pairs (i.e., test examples) and evaluating its predicted outputs against the known outputs. The performance can be measured using various metrics, such as accuracy, precision, recall, or mean squared error.
7. Model optimization: Fine-tuning the model to improve its performance. This might involve adjusting the model’s hyperparameters (e.g., learning rate, regularization strength) or using advanced techniques like cross-validation or grid search to find the best parameter settings.
8. Model deployment: Integrating the trained model into a production environment or a real-world application. This might involve implementing the model as a software component, deploying it on a cloud-based platform, or integrating it into an existing system.
Throughout this process, machine learning algorithms use statistical techniques to identify patterns, make predictions, or classify data into different categories. The performance of these algorithms heavily relies on the quality of the data, the selection of appropriate features, and the availability of sufficient training examples.
