Frequently Asked Questions

How does Machine Learning work?

Machine Learning is a branch of Artificial Intelligence that enables computer systems to learn and improve from experience without being explicitly programmed. By using algorithms and statistical models, ML systems analyze and interpret large sets of data to make predictions or decisions. Through a process known as training, these systems learn patterns and structures within the data and use this knowledge to make informed predictions or decisions on new, unseen data.

What is a Neural Network?

A Neural Network is a computational model inspired by the human brain’s neural structure and functioning. It consists of interconnected nodes, called neurons, organized in layers. Each neuron processes and sends information to other neurons, allowing the network to perform complex computations. Neural Networks are commonly used in Machine Learning to solve complex problems, such as image recognition, natural language processing, and sentiment analysis.

• Accuracy: The proportion of correct predictions.
• Precision: The proportion of true positive predictions out of all positive predictions.
• Recall: The proportion of true positive predictions out of all actual positive instances.
• F1 Score: A weighted average of precision and recall.
• Mean Squared Error (MSE): The average of the squared differences between predicted and actual values.

What is overfitting in Machine Learning?

Overfitting occurs when a Machine Learning model performs well on the training data but fails to generalize well on unseen data. It happens when the model becomes too complex and starts to memorize noise and outliers in the training data instead of learning the underlying patterns. Overfitting can be avoided by using techniques like cross-validation, regularization, and early stopping.

What is the difference between supervised and unsupervised learning?

Supervised learning involves training a model with labeled examples, where the input data is accompanied by corresponding output labels. The objective is to learn a mapping from input to output based on this labeled dataset. In contrast, unsupervised learning deals with unlabeled data. The goal is to discover hidden patterns, structures, or relationships within the data without any prior knowledge about the output.

What is Deep Learning?

Deep Learning is a subset of Machine Learning that focuses on neural networks with multiple hidden layers. These deep neural networks can automatically learn hierarchical representations of data, enabling them to capture complex patterns and relationships. Deep Learning has achieved significant breakthroughs in areas such as image and speech recognition, natural language processing, and autonomous driving.

How much data is needed for training a Machine Learning model?

The amount of data needed for training a Machine Learning model depends on several factors, including the complexity of the problem, the quality of the data, and the algorithm used. In general, having more diverse and representative data leads to better performance. However, it is also important to balance the quantity and quality of the data as overfitting can occur when there is insufficient data or an imbalance between different classes or categories.

What are the ethical implications of using Machine Learning?

The use of Machine Learning raises various ethical considerations. Some potential implications include:

• Bias and fairness: ML algorithms can perpetuate existing biases or discriminate against certain individuals or groups.
• Privacy and data protection: ML systems often require access to large amounts of personal data, raising concerns about privacy and data security.
