Deep learning Wikipedia Deep learning is a subset of machine learning that is concerned with neural networks: In that sense, deep learning represents an unsupervised learning algorithm that learns representations of data through the use of neural nets.

A generative model will learn categories of data while a discriminative model will simply learn the distinction between different categories of data. Discriminative models will generally outperform generative models on classification tasks.

Q What cross-validation technique would you use on a time series dataset? Using k-fold cross-validation for time-series model selection CrossValidated Instead of using standard k-folds cross-validation, you have to pay attention to the fact that a time series is not randomly distributed data — it is inherently ordered by chronological order.

Pruning decision trees Pruning is what happens in decision trees when branches that have weak predictive power are removed in order to reduce the complexity of the model and increase the predictive accuracy of a decision tree model.

Pruning can happen bottom-up and top-down, with approaches such as reduced error pruning and cost complexity pruning. Reduced error pruning is perhaps the simplest version: While simple, this heuristic actually comes pretty close to an approach that would optimize for maximum accuracy.

Q Which is more important to you— model accuracy, or model performance? Accuracy paradox Wikipedia This question tests your grasp of the nuances of machine learning model performance! Machine learning interview questions often look towards the details.

There are models with higher accuracy that can perform worse in predictive power — how does that make sense? Well, it has everything to do with how model accuracy is only a subset of model performance, and at that, a sometimes misleading one. For example, if you wanted to detect fraud in a massive dataset with a sample of millions, a more accurate model would most likely predict no fraud at all if only a vast minority of cases were fraud.

However, this would be useless for a predictive model — a model designed to find fraud that asserted there was no fraud at all!

How to Format a Research Paper

How would you use it? It is a weighted average of the precision and recall of a model, with results tending to 1 being the best, and those tending to 0 being the worst. Q How would you handle an imbalanced dataset? That leads to problems: Here are a few tactics to get over the hump:A Research Concept Paper serves as a preliminary form of communication regarding a proposed research project.

Why a Scientific Format? The scientific format may seem confusing for the beginning science writer due to its rigid structure which is so different from writing in the humanities. One reason for using this format is that it is a means of efficiently communicating scientific findings to the broad community of scientists in a .
