The world has changed since Machine Learning, Artificial Intelligence, and Deep learning were introduced globally and will rise continuously in the upcoming years. In this blog of top 50 Machine Learning Interview Questions, Wissenhive has collected the most frequently asked questions by interviewers. These questions are searched after consulting with machine learning experts. Go through these questions and succeed in your career!
Machine learning refers to a branch of artificial intelligence and the study of computer algorithms that focus on building models and applications based on sample data to improve their accuracy and make decisions or predictions without being programmed to do so. Machine learning concentrates on developing computer programs that can obtain and use data to leave for themselves.
There are three types of machine learning, and those are
There are three different types of approaches in machine learning, and those are
There are five different types of function included in supervised learning, which includes
There are five different types of function included in unsupervised learning, which includes
There are numerous means to select important variables from a data set which includes
Selection bias refers to a statistical error that causes bias in the experiment of the sampling portion. It is associated with research where participants’ selection is not random such as
It leads to an inaccurate conclusion if it is not identified.
There are four different types of selected bias in machine learning, and those are
There are two components of the Bayesian logical program, and those are
Inductive machine learning refers to a process of learning by formulating general hypotheses that fit observed training data. It requires no prior knowledge and justifies statistical inference. Some of the famous methods of inductive machine learning are
Analytical machine learning also refers to a process of learning by formulating general hypotheses that fit domain theory. It learns from scarce data and justified deductive interference. Some of the famous methods of inductive machine learning are
The normal distribution includes various factors or properties, which includes
Pruning in machine learning refers to a data compression technique and search algorithms that reduce decision trees size by eliminating different sections of the tree that are redundant and non-critical to classify instances. The benefits of pruning are
The array is a well-indexed element that specifically makes accessing elements easier. The operations like deletion and insertion work faster in an array with a fixed size. It assigns memory during compile timing, stores elements consecutively, and provides inefficient utilization of memory.
Listed lists refer to a cumulative manner of accessed elements that takes linear time to make operations a little slower. It is flexible, dynamic, and allocates memory during runtime or execution. It also randomly stores elements and efficient memory utilization.
The full form of EDA is Exploratory Data Analysis that helps Data analysts to approach and understand analyzing data sets to summarize their key characteristics by using data visualization methods and statistical graphs. The techniques that are included in EDA are
The ROC curve’s full form is the Receiver Operating Characteristic curve, which refers to a graphical plot or fundamental tool that illustrates the diagnostic test evaluation of a binary classifier system and provides a plot of the true positive against false-positive rates for various possible cut-off points.
Overfitting is a type of modeling error that happens when data are closely packed in a limited area of data points. It makes the simple model an overly complex model to explain oddities in the data under study and negatively influence the model’s performance.
There are many different methods to avoid overfitting, but the main and effective methods are
There are six different types of cross-validation technique, and those are
Statistical learning is a technique that allows predictions and function learning from an observed data set to make future or unseen data predictions. This technique provides a performance guarantee on unseen future data based on the statistical assumption’s data generating process.
A neural network refers to a computational system of learning by network functions to translate and understand an input of data into desired input. The human brain’s neurons inspired this concept as it understands inputs and functions together from humans’ senses. It is one of the various approaches and tools used in machine learning algorithms.
