Study Notes

Artificial Neural Networks Basics

Dendrites in Artificial Neural Networks represent the inputs to a neuron, receiving signals from other neurons.
Synapses in Artificial Neural Networks represent the connections between neurons, enabling them to exchange signals.
Neurons in Artificial Neural Networks are interconnected through synapses, allowing the transmission of signals between them.
The axon in Artificial Neural Networks represents the output of a neuron, transmitting signals to other neurons.

Artificial Neural Networks Purpose

The primary purpose of an Artificial Neural Network in Artificial Intelligence is to recognize patterns and make predictions or decisions based on input data.

Density Estimation

The oldest and most popular method for estimating density is the histogram method.
The main purpose of the histogram density estimator function is to estimate the underlying distribution of the data.
The estimation near the boundaries is affected by the choice of bin width and the number of bins in the histogram.

Histogram Density Estimator Function

The 'hist_pdf' code provided estimates the probability density function (PDF) of a dataset using the histogram method.

Learning Algorithms

Instance-based or memory-based learning algorithms, such as k-Nearest Neighbors (k-NN), rely on storing instances of the training data and using them to make predictions.
