Machine Learning:-Machine learning is a branch of artificial intelligence that involves teaching machines to learn from data patterns and make predictions or decisions without being explicitly programmed for each task. It enables systems to improve their performance over time by recognizing patterns, learning from experiences, and adjusting their behavior accordingly.ML is a branch of AI that aims to train machines to learn and act like humans and to improve their learning in autonomous fashion through data fusion and real-world interactions, while DL refers to a newer generation of ML algorithms for extracting and learning hierarchical representations of input data[4]. ML, a subdomain of artificial intelligence (AI), refers broadly to computer algorithms that can automatically learn from data[5].

ML Techniques:

1.Neural Networks:

Neural networks are a fundamental component of machine learning. They're a subset of algorithms within the broader field of machine learning, specifically falling under the category of deep learning due to their multilayered structure.These networks excel in recognizing patterns and structures within data. Through training on large datasets, they can learn to recognize features and make predictions or classifications. Neural networks have shown significant prowess in various machine learning tasks, such as image and speech recognition, language translation, autonomous vehicles, and more.Their ability to automatically learn representations from raw data makes them powerful tools in solving complex problems where traditional algorithms might struggle.

2. Decision Trees:Decision trees are another essential machine learning technique used for both classification and regression tasks. They work by recursively partitioning the data into subsets based on features, creating a tree-like structure where each internal node represents a feature, each branch signifies a decision based on that feature, and each leaf node holds the output (class label or numerical value).

During training, the decision tree algorithm selects the most significant features and creates split points to best differentiate between classes or predict values. It continues this process to build a tree that can make predictions or classifications based on the input features.

Decision trees are popular due to their interpretability, as they mimic human decision-making processes and are easily visualized. Additionally, they can handle both numerical and categorical data and are less sensitive to outliers compared to some other algorithms. However, they can be prone to overfitting if not appropriately tuned or if the tree grows too deep. Techniques like pruning or using ensemble methods like Random Forests help alleviate these issues

Deep learning has gained immense popularity due to its ability to automatically learn intricate patterns and representations directly from raw data. Some prominent deep learning architectures include Convolutional Neural Networks (CNNs) for image-related tasks, Recurrent Neural Networks (RNNs) for sequential data like text and time series, and variants like Long Short-Term Memory networks (LSTMs) and Transformers used in natural language processing and machine translation.These models often require substantial computational resources for training due to their depth and complexity but have demonstrated exceptional performance in various domains, achieving state-of-the-art results in image recognition, speech processing, language translation, and other fields where understanding complex relationships in data is crucial.
