Describe the purpose of regularization in machine learning models.

Regularization is a technique used to prevent overfitting by adding a penalty term to the loss function, which discourages large model weights and encourages simpler models. Signup and view all the answers

What is the bias-variance tradeoff in machine learning?

The bias-variance tradeoff refers to the tradeoff between the error introduced by a model's simplifying assumptions (bias) and the error introduced by the model's sensitivity to noise in the data (variance). Signup and view all the answers

Study Notes

Deep Learning Quiz

Image processing is primarily done using CNN (Convolutional Neural Networks).
The most commonly used activation function in deep learning models is ReLU (Rectified Linear Unit).
Dropout is used to prevent overfitting in deep learning models.
Convolutional layers are not used in RNNs to handle sequential data.
In a GAN, the generator tries to generate fake data that resembles real data, not to distinguish between real and fake data.
LSTM networks are designed to address the vanishing gradient problem in standard RNNs.

Artificial Intelligence Quiz

Neural Networks is the AI technique used to solve problems by imitating the human brain.
A* algorithm is commonly used in decision-making AI systems to minimize the total path cost.
The purpose of a heuristic function is to estimate the best solution.
Turing Test is used to determine whether a machine can exhibit intelligent behavior equivalent to a human.
Machine learning is a subset of artificial intelligence.
AI systems do not always require large datasets to function properly.

Machine Learning Quiz

Decision Tree is a supervised learning algorithm.
Log Loss is often used to evaluate the performance of classification models.
SMOTE is a technique used to handle imbalanced datasets.
In k-fold cross-validation, the data is divided into k subsets and the model is trained k times.
PCA is used for dimensionality reduction.
Overfitting occurs when a model performs well on the training data but poorly on new, unseen data.

Natural Language Processing Quiz

The main purpose of tokenization is to break down text into meaningful units.
Word2Vec is a model commonly used for word embeddings.
The primary advantage of using Transformer models is capturing long-range dependencies.
Named Entity Recognition (NER) is used to classify words into predefined categories.
Stemming and lemmatization both aim to reduce words to their base forms, but stemming does not ensure valid words.
In BERT, the attention mechanism is used to focus on relevant parts of the input text.
