Praca w Danii / How does machine learning work?
« Ostatnia wiadomość wysłana przez Priyasingh dnia Dzisiaj o 09:52:08 »Machine learning is a subset of artificial intelligence (AI) that focuses on developing algorithms and statistical models that enable computers to learn from and make predictions or decisions based on data. Here is a high-level overview of how machine learning works:
Data Collection: The first step in any machine learning project is to collect relevant data. This data can come from various sources such as sensors, databases, or the internet.
Data Preprocessing: Once the data is collected, it needs to be cleaned and preprocessed to remove noise, handle missing values, and transform it into a format suitable for the machine learning algorithm.
Feature Selection and Engineering: In this step, relevant features (variables) are selected from the data. Feature engineering involves creating new features or transforming existing features to improve the performance of the model.

Model Selection: Depending on the problem at hand, a suitable machine learning algorithm is chosen. Common types of machine learning algorithms include linear regression, decision trees, support vector machines, neural networks, and clustering algorithms.
Model Training: The selected algorithm is trained on the preprocessed data to learn the underlying patterns and relationships. During training, the model adjusts its parameters iteratively to minimize the error between the predicted output and the actual output.
Model Evaluation: Once the model is trained, it is evaluated using a separate dataset (validation or test set) to assess its performance. Common evaluation metrics include accuracy, precision, recall, F1 score, and others, depending on the problem.

Model Tuning: If the model's performance is not satisfactory, hyperparameters are tuned to improve its performance. Hyperparameters are parameters that are set before the learning process begins, such as the learning rate in neural networks or the depth of a decision tree.
Model Deployment: After the model is trained and evaluated satisfactorily, it can be deployed to make predictions or decisions on new, unseen data. Deployment can involve integrating the model into existing systems or creating applications that use the model.
Monitoring and Maintenance: Once the model is deployed, it is important to monitor its performance over time and retrain it periodically with new data to ensure that it continues to make accurate predictions.
