# What is grid search used for?

## What is grid search used for?

Grid-search is used to find the optimal hyperparameters of a model which results in the most ‘accurate’ predictions.

## What is model Overfitting?

Overfitting is a modeling error that occurs when a function is too closely fit to a limited set of data points. Thus, attempting to make the model conform too closely to slightly inaccurate data can infect the model with substantial errors and reduce its predictive power.

## What can cause Overfitting?

Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data. This means that the noise or random fluctuations in the training data is picked up and learned as concepts by the model.

## How do I fix Overfitting neural network?

But, if your neural network is overfitting, try making it smaller.Early Stopping. Early stopping is a form of regularization while training a model with an iterative method, such as gradient descent. Use Data Augmentation. Use Regularization. Use Dropouts.

## What is high bias?

A high bias model typically includes more assumptions about the target function or end result. A low bias model incorporates fewer assumptions about the target function. A linear algorithm often has high bias, which makes them learn fast.
