Embeddings are a way to represent words or phrases as vectors in a high-dimensional space, capturing semantic relationships.

• Embeddings are important for tasks like natural language processing, where words need to be represented in a meaningful way.

• They can be created using techniques like Word2Vec, GloVe, or using neural networks like Word Embeddings.

• Embeddings help in capturing semantic relationships between words, al...read more

Encoder-decoder is a neural network architecture used for tasks like machine translation.

• Encoder processes input data and generates a fixed-length representation

• Decoder uses the representation to generate output sequence

• Example: Seq2Seq model for translating English to French

Types of jobs in Kotlin coroutine include launch, async, withContext, and runBlocking.

• launch: starts a new coroutine without blocking the current thread

• async: starts a new coroutine and returns a Deferred object with a result

• withContext: switches the coroutine context within a coroutine

• runBlocking: blocks the current thread until the coroutine inside it is completed

• It ensures that data emissions are only observed when the lifecycle is in the appropriate state

• Example: Using Flow with LiveData to update UI components based on lifecycle events

Inline functions are functions that are expanded in place at the call site, while high-order functions are functions that can take other functions as parameters or return them.

• Inline functions are expanded in place at the call site to improve performance.

• High-order functions can take other functions as parameters or return them.

• Example of high-order function: map() function in Kotlin.
