Multicollinearity is a phenomenon in which two or more predictor variables in a multiple regression model are highly correlated.

• Multicollinearity can lead to issues in the interpretation of regression coefficients, as it becomes difficult to determine the individual impact of each predictor variable on the outcome.

• It can inflate the standard errors of the coefficients, making them unstable and unreliable.

• Multicollinearity can also make it challenging to identify the most impo...read more

Word2Vec is a technique used to create word embeddings by representing words as vectors in a high-dimensional space.

• Word2Vec is a popular algorithm for generating word embeddings in natural language processing.

• It uses a neural network model to learn the relationships between words based on their context in a large corpus of text.

• Word2Vec can be used to find similarities between words, perform word arithmetic, and improve the performance of various NLP tasks.

Sharding is a database partitioning technique to improve performance and scalability by distributing data across multiple servers.

• Sharding involves breaking up a database into smaller, more manageable parts called shards

• Each shard contains a subset of the data, allowing for parallel processing and improved performance

• Examples of sharding implementations include MongoDB's sharded clusters and MySQL's partitioning feature

Narrow AI refers to AI systems that are designed for a specific task or narrow range of tasks.

• Narrow AI is also known as weak AI.

• These systems are not capable of general intelligence or understanding beyond their specific task.

• Examples of narrow AI include virtual assistants like Siri or Alexa, recommendation algorithms on streaming platforms, and self-driving cars.

AI is used in real life for various applications such as virtual assistants, recommendation systems, autonomous vehicles, and fraud detection.

• Virtual assistants like Siri, Alexa, and Google Assistant use AI to understand and respond to user queries.

• Recommendation systems on platforms like Netflix and Amazon use AI to suggest personalized content based on user preferences.

• Autonomous vehicles use AI for navigation, object detection, and decision-making while driving.

• Fraud detec...read more

Bias-variance tradeoff is the balance between underfitting and overfitting in machine learning models.

• Bias refers to the error from erroneous assumptions in the learning algorithm, leading to underfitting.

• Variance refers to the error from sensitivity to fluctuations in the training set, leading to overfitting.

• The tradeoff involves finding the right level of model complexity to minimize both bias and variance.

• Regularization techniques like Lasso and Ridge regression can help i...read more

The range of given observations refers to the difference between the highest and lowest values in a set of data.

• Range is calculated by subtracting the lowest value from the highest value in the data set.

• For example, in a set of numbers {2, 5, 8, 10}, the range would be 10 - 2 = 8.

• Range is a measure of variability in the data.
