Long Short-Term Memory (LSTM)

LSTM models outperform traditional RNNs in many sequence learning tasks by effectively capturing both short-term patterns and long-term dependencies. They are widely used in modern AI systems, often as a backbone for tasks requiring contextual understanding over time.

Variance

Variance measures how much a model's predictions change with different training data. High variance means the model overfits and captures noise. It's key in the bias-variance tradeoff to balance model accuracy and generalization.

Cosine Similarity

Cosine similarity measures the similarity between two vectors by calculating the cosine of the angle between them. It is widely used in text matching, search engines, recommendation systems, and AI models to compare documents, queries, and user preferences.

Vanishing Gradient

The vanishing gradient problem happens when training deep networks or RNNs, where the gradients (used to update weights) become very small as they move backward through the network. This makes it hard for earlier layers or time steps to learn anything, causing the model to forget long-term patterns.

Recurrent Neural Network (RNN)

Recurrent Neural Network is a type of neural network that is designed to work with data that comes in sequences, like a list of words, time-series data, or steps in a process.

Backpropagation Through Time

Backpropagation Through Time (BPTT) is an extension of the standard backpropagation algorithm used to train recurrent neural networks (RNNs). It works by unrolling the RNN over a sequence of time steps and calculating gradients for each time step.

Backpropagation

Backpropagation is a fundamental algorithm used to train artificial neural networks. It is used to minimize the error between the predicted output and the actual output by adjusting the network's weights.

post

Weight in Neural Network

In a neural network, weights are the adjustable parameters that control the strength of the connections between neurons in the layers.

post

Derivative of Activation Functions

The derivative of activation functions is crucial in the training of neural networks, especially during the backpropagation process.

post

Derivative of Exponential

The exponential function is unique in calculus because it is the only function that is its own derivative. This property makes it extremely important in various fields like physics, economics, and engineering.

post

Cross Entropy

Cross-entropy is a loss function commonly used in machine learning, particularly in classification tasks. It measures the difference between two probability distributions: the true labels and the predicted probabilities.
