Study Notes
Maximum Likelihood Estimation (MLE)
- The goal of MLE is to find the parameters that make the observed data most likely.
The Likelihood Function in MLE
- The likelihood function represents the probability of observing the data given a set of model parameters.
MLE Process
- After defining the likelihood function, the next step is to maximize it to find the maximum likelihood estimate (MLE) of the parameters.
- The MLE process involves finding the values of the parameters that maximize the likelihood function.
MLE in Supervised Learning
- MLE is considered a powerful technique in supervised learning because it allows for the estimation of model parameters from observed data, enabling accurate predictions.
Errors in Machine Learning
- Bias and variance are related to reducible errors in machine learning, which can be minimized by adjusting the model's complexity.
- The purpose of errors in machine learning is to measure the difference between the model's predictions and the true labels, guiding model improvement.
Reducible Errors in Machine Learning
- Reducible errors can be minimized by improving the model or collecting more data.
Inverse Gaussian Distribution
- A key property of the inverse Gaussian distribution, compared to the Gaussian distribution, is its asymmetry.
- The inverse Gaussian distribution is skewed, with a longer tail on the right side, making it useful for modeling data with skewed distributions, such as survival times or financial returns.
- The inverse Gaussian distribution is useful for modeling certain types of data, such as those with non-normal or skewed distributions.
