There are other techniques as well –Cluster-Based Over Sampling – In this case, the K-means clustering algorithm is independently applied to minority and majority class instances. Enhance the performance of machine learning models. Answer: Option B 12. It implies that the value of the actual class is no and the value of the predicted class is also no. Ans. One-hot encoding is the representation of categorical variables as binary vectors. Given that the focus of the field of machine learning is “learning,” there are many types that you may encounter as a practitioner. Poisson distribution helps predict the probability of certain events happening when you know how often that event has occurred. append() – Adds an element at the end of the listcopy() – returns a copy of a list.reverse() – reverses the elements of the listsort() – sorts the elements in ascending order by default. Ans. Different people may enjoy different methods. Explain the process. Boosting is the technique used by GBM. 1 • Xiaoying Zhuang. Explain the process. This technique is good for Numerical data points. it is a circle, inside a circle is one class, outside is another class). Ans. Ans. Cross-validation is a technique which is used to increase the performance of a machine learning algorithm, where the machine is fed sampled data out of the same data for a few times. It involves an agent that interacts with its environment by producing actions & discovering errors or rewards. The regularization parameter (lambda) serves as a degree of importance that is given to miss-classifications. Deep Learning, on the other hand, is able to learn through processing data on its own and is quite similar to the human brain where it identifies something, analyse it, and makes a decision.The key differences are as follow: Supervised learning technique needs labeled data to train the model. The values of weights can become so large as to overflow and result in NaN values. Using one-hot encoding increases the dimensionality of the data set. Ans. The manner in which data is presented to the system. Selection bias stands for the bias which was introduced by the selection of individuals, groups or data for doing analysis in a way that the proper randomization is not achieved. Amazon uses a collaborative filtering algorithm for the recommendation of similar items. Let us come up with a logic for the same. Where-as a likelihood function is a function of parameters within the parameter space that describes the probability of obtaining the observed data. Correlation quantifies the relationship between two random variables and has only three specific values, i.e., 1, 0, and -1. Since there is no skewness and its bell-shaped. The sampling is done so that the dataset is broken into small parts of the equal number of rows, and a random part is chosen as the test set, while all other parts are chosen as train sets. Certainly, many techniques in machine learning derive from the e orts of psychologists to make more precise their theories of animal and human learning through computational models. This is a trick question, one should first get a clear idea, what is Model Performance? It is used as a performance measure of a model/algorithm. ML can be considered as a subset of AI. If data shows non-linearity then, the bagging algorithm would do better. For Over Sampling, we upsample the Minority class and thus solve the problem of information loss, however, we get into the trouble of having Overfitting. Answer: Option D In order to maintain the optimal amount of error, we perform a tradeoff between bias and variance based on the needs of a business. Practice Test: Question Set - 07 1. By doing so, it allows a better predictive performance compared to a single model. It can be done by converting the 3-dimensional image into a single-dimensional vector and using the same as input to KNN. Since the target column is categorical, it uses linear regression to create an odd function that is wrapped with a log function to use regression as a classifier. This family of algorithm shares a common principle which treats every pair of features independently while being classified. For datasets with high variance, we could use the bagging algorithm to handle it. Answer: A lot of machine learning interview questions of this type will involve the implementation of machine learning models to a company’s problems. Another technique that can be used is the elbow method. An example of this would be a coin toss. The next step would be to take up a ML course, or read the top books for self-learning. Then, even if a non-ideal algorithm is used, results come out to be accurate. PCA takes into consideration the variance. When the algorithm has limited flexibility to deduce the correct observation from the dataset, it results in bias.

The model is trained on an existing data set before it starts making decisions with the new data.The target variable is continuous: Linear Regression, polynomial Regression, quadratic Regression.The target variable is categorical: Logistic regression, Naive Bayes, KNN, SVM, Decision Tree, Gradient Boosting, ADA boosting, Bagging, Random forest etc. Akaike Information Criteria (AIC): In simple terms, AIC estimates the relative amount of information lost by a given model. Search. Ans. 13. Examples include weights, biases etc. 1. It implies that the value of the actual class is yes and the value of the predicted class is also yes. This type of function may look familiar to you if you remember y = mx + b from high school. They are superior to individual models as they reduce variance, average out biases, and have lesser chances of overfitting. The first step is to understand the basic principles of the subject and learn a few key concepts such as algorithms and data structures, coding capabilities, calculus, linear algebra, statistics. Confusion Metric can be further interpreted with the following terms:-. Lasso(L1) and Ridge(L2) are the regularization techniques where we penalize the coefficients to find the optimum solution. The proportion of classes is maintained and hence the model performs better. Therefore, to find the last occurrence of a character, we reverse the string and find the first occurrence, which is equivalent to the last occurrence in the original string. Highly scalable. Every machine learning problem tends to have its own particularities. Exploratory Data Analysis (EDA) helps analysts to understand the data better and forms the foundation of better models. A subset of data is taken from the minority class as an example and then new synthetic similar instances are created which are then added to the original dataset. This is a two layer model with a visible input layer and a hidden layer which makes stochastic decisions for the read more…. If we have more features than observations, we have a risk of overfitting the model. Later, we reverse the array, find the first occurrence position value, and get the index by finding the value len – position -1, where position is the index value. Machine Learning. Marginal likelihood is the denominator of the Bayes equation and it makes sure that the posterior probability is valid by making its area 1. The bias-variance decomposition essentially decomposes the learning error from any algorithm by adding the bias, the variance and a bit of irreducible error due to noise in the underlying dataset. It is typically a symmetric distribution where most of the observations cluster around the central peak. Essentially, if you make the model more complex and add more variables, you’ll lose bias but gain some variance — in order to get the optimally reduced amount of error, you’ll have to trade off bias and variance. 1 denotes a positive relationship, -1 denotes a negative relationship, and 0 denotes that the two variables are independent of each other. If one adds more features while building a model, it will add more complexity and we will lose bias but gain some variance. What is Multilayer Perceptron and Boltzmann Machine? Example – “it’s possible to have a false negative—the test says you aren’t pregnant when you are”. They are as follow: Yes, it is possible to test for the probability of improving model accuracy without cross-validation techniques. Once a Fourier transform applied on a waveform, it gets decomposed into a sinusoid. It is mostly used in Market-based Analysis to find how frequently an itemset occurs in a transaction. They find their prime usage in the creation of covariance and correlation matrices in data science. When we are trying to learn Y from X and the hypothesis space for Y is infinite, we need to reduce the scope by our beliefs/assumptions about the hypothesis space which is also called inductive bias. Artificial Intelligence (AI) is the domain of producing intelligent machines. This relation between Y and X, with a degree of the polynomial as 1 is called Linear Regression. We need to explore the data using EDA (Exploratory Data Analysis) and understand the purpose of using the dataset to come up with the best fit algorithm. ● SVM is found to have better performance practically in most cases. Therefore, this score takes both false positives and false negatives into account. in Machine Design … What if the size of the array is huge, say 10000 elements. For example, how long a car battery would last, in months. Example: Target column – 0,0,0,1,0,2,0,0,1,1 [0s: 60%, 1: 30%, 2:10%] 0 are in majority. NLP or Natural Language Processing helps machines analyse natural languages with the intention of learning them. Increasing the number of epochs results in increasing the duration of training of the model. While, data mining can be defined as the process in which the unstructured data tries to extract knowledge or unknown interesting patterns. Questions and answers - MCQ with explanation on Computer Science subjects like System Architecture, Introduction to Management, Math For Computer Science, DBMS, C Programming, System Analysis and Design, Data Structure and Algorithm Analysis, OOP and Java, Client Server Application Development, Data Communication and Computer Networks, OS, MIS, Software Engineering, AI, Web Technology and … Hence, it is a type of classification technique and not a regression. This comprises solving questions either on the white-board, or solving it on online platforms like HackerRank, LeetCode etc. Higher variance directly means that the data spread is big and the feature has a variety of data. Hence some classes might be present only in tarin sets or validation sets. The model learns through observations and deduced structures in the data.Principal component Analysis, Factor analysis, Singular Value Decomposition etc. The gamma defines influence. Low values meaning ‘far’ and high values meaning ‘close’. The curve is symmetric at the center (i.e. They may occur due to experimental errors or variability in measurement. At times when the model begins to underfit or overfit, regularization becomes necessary. Elements are stored consecutively in arrays. imbalanced. # Explain the terms AI, ML and Deep Learning?# What’s the difference between Type I and Type II error?# State the differences between causality and correlation?# How can we relate standard deviation and variance?# Is a high variance in data good or bad?# What is Time series?# What is a Box-Cox transformation?# What’s a Fourier transform?# What is Marginalization? If the cost of false positives and false negatives are very different, it’s better to look at both Precision and Recall. Naïve Bayes Classifier Algorithm. A real number is predicted. learn linear fictions from your data that map your input to scores like so: scores = Wx + b. Ensemble learning helps improve ML results because it combines several models. This section focuses on "Data Mining" in Data Science. We assume that there exists a hyperplane separating negative and positive examples. Ans. Answer: An approach to the design of learning algorithms that is inspired by the fact that when people encounter new situations, they often explain them by reference to familiar experiences, adapting the explanations to fit the new situation Here, we have compiled a list of frequently asked top 100 machine learning interview questions that you might face during an interview. Ans. We can’t represent features in terms of their occurrences. Input the data set into a clustering algorithm, generate optimal clusters, label the cluster numbers as the new target variable. The values of hash functions are stored in data structures which are known hash table. Machine Learning Foundations Machine Learning with PythonStatistics for Machine Learning Advanced Statistics for Machine Learning. At any given value of X, one can compute the value of Y, using the equation of Line. Higher the area under the curve, better the prediction power of the model. In ridge, the penalty function is defined by the sum of the squares of the coefficients and for the Lasso, we penalize the sum of the absolute values of the coefficients. Type I and Type II error in machine learning refers to false values. Try it out using a pen and paper first. 15. Ans. The number of clusters can be determined by finding the silhouette score. An example would be the height of students in a classroom. The p-value gives the probability of the null hypothesis is true. The most common way to get into a machine learning career is to acquire the necessary skills. 8. SVM algorithms have basically advantages in terms of complexity. A voting model is an ensemble model which combines several classifiers but to produce the final result, in case of a classification-based model, takes into account, the classification of a certain data point of all the models and picks the most vouched/voted/generated option from all the given classes in the target column. – These are the correctly predicted positive values. If Performance means speed, then it depends upon the nature of the application, any application related to the real-time scenario will need high speed as an important feature. Answer: Option B We can store information on the entire network instead of storing it in a database. The meshgrid( ) function in numpy takes two arguments as input : range of x-values in the grid, range of y-values in the grid whereas meshgrid needs to be built before the contourf( ) function in matplotlib is used which takes in many inputs : x-values, y-values, fitting curve (contour line) to be plotted in grid, colours etc. Artificial Intelligence MCQ question is the important chapter for … The model complexity is reduced and it becomes better at predicting. The phrase is used to express the difficulty of using brute force or grid search to optimize a function with too many inputs. Given an array arr[] of N non-negative integers which represents the height of blocks at index I, where the width of each block is 1. AUC (area under curve). Subsequently, each cluster is oversampled such that all clusters of the same class have an equal number of instances and all classes have the same size. Values below the threshold are set to 0 and those above the threshold are set to 1 which is useful for feature engineering. L1 corresponds to setting a Laplacean prior on the terms. Association rule generation generally comprised of two different steps: Support is a measure of how often the “item set” appears in the data set and Confidence is a measure of how often a particular rule has been found to be true. Therefore, this prevents unnecessary duplicates and thus preserves the structure of the copied compound data structure. Bias stands for the error because of the erroneous or overly simplistic assumptions in the learning algorithm . 6. Learn programming languages such as C, C++, Python, and Java. Now that we have understood the concept of lists, let us solve interview questions to get better exposure on the same. It is the sum of the likelihood residuals. 3. Use machine learning algorithms to make a model: can use naive bayes or some other algorithms as well. Learn Artificial Intelligence MCQ questions & answers are available for a Computer Science students to clear GATE exams, various technical interview, competitive examination, and another entrance exam. The most popular distribution curves are as follows- Bernoulli Distribution, Uniform Distribution, Binomial Distribution, Normal Distribution, Poisson Distribution, and Exponential Distribution. There is a list of Normality checks, they are as follow: Linear Function can be defined as a Mathematical function on a 2D plane as,  Y =Mx +C, where Y is a dependent variable and X is Independent Variable, C is Intercept and M is slope and same can be expressed as Y is a Function of X or Y = F(x). It’s helpful in reducing the error. You need to extract features from this data before supplying it to the algorithm. With the remaining 95% confidence, we can say that the model can go as low or as high [as mentioned within cut off points]. The most important features which one can tune in decision trees are: Ans. Fourier transform is closely related to Fourier series. Machine Learning Interview Questions and Answer for 2021. Khader M. Hamdia. Although an understanding of the complete system is usually considered necessary for good design, leading theoretically to a top-down approach, most software projects attempt to make use of existing code to some degree. is the most intuitive performance measure and it is simply a ratio of correctly predicted observation to the total observations. – In this case, the K-means clustering algorithm is independently applied to minority and majority class instances. By doing so, it allows a better predictive performance compared to a single model. Popularity based recommendation, content-based recommendation, user-based collaborative filter, and item-based recommendation are the popular types of recommendation systems. The same calculation can be applied to a naive model that assumes absolutely no predictive power, and a saturated model assuming perfect predictions. A pandas dataframe is a data structure in pandas which is mutable. Also Read: Overfitting and Underfitting in Machine Learning. How are they stored in the memory? Standard deviation refers to the spread of your data from the mean. Plot all the accuracies and remove the 5% of low probability values. Let us start from the end and move backwards as that makes more sense intuitionally. If data is correlated PCA does not work well. Now that we know what arrays are, we shall understand them in detail by solving some interview questions. The advantages of decision trees are that they are easier to interpret, are nonparametric and hence robust to outliers, and have relatively few parameters to tune.On the other hand, the disadvantage is that they are prone to overfitting. It can also refer to several other issues like: Dimensionality reduction techniques like PCA come to the rescue in such cases. Most of the data points are around the median. Submenu Toggle Interview Guide; Technical Questions; Machine Design MCQ Objective Question and Answers Part 4. That means about 32% of the data remains uninfluenced by missing values. Correct? This assumes that data is very well behaved, and you can find a perfect classifier – which will have 0 error on train data. It works on the fundamental assumption that every set of two features that is being classified is independent of each other and every feature makes an equal and independent contribution to the outcome. Classifier penalty, classifier solver and classifier C are the trainable hyperparameters of a Logistic Regression Classifier. If your data is on very different scales (especially low to high), you would want to normalise the data. Therefore we can just swap the elements. Collinearity is a linear association between two predictors. Often it is not clear which basis functions are the best fit for a given task. The performance metric of ROC curve is AUC (area under curve). and then handle them based on the visualization we have got. What is Marginalisation? This can be dangerous in many applications. Tanuja is an aspiring content writer. To handle outliers, we can cap at some threshold, use transformations to reduce skewness of the data and remove outliers if they are anomalies or errors. How can we relate standard deviation and variance? Variation Inflation Factor (VIF) is the ratio of variance of the model to variance of the model with only one independent variable. Machine learning models are about making accurate predictions about the situations, like Foot Fall in restaurants, Stock-Price, etc. # we use two arrays left[ ] and right[ ], which keep track of elements greater than all# elements the order of traversal respectively. Random forests are a significant number of decision trees pooled using averages or majority rules at the end. In simple words they are a set of procedures for solving new problems based on the solutions of already solved problems in the past which are similar to the current problem. Nevertheless, as the discipline advances, there are emerging patterns that suggest an ordered process to solving those problems. Exactly half of the values are to the left of center and exactly half the values are to the right. A very small chi-square test statistics implies observed data fits the expected data extremely well. Normalization refers to re-scaling the values to fit into a range of [0,1]. It serves as a tool to perform the tradeoff. Some design approaches … Hence we use Gaussian Naive Bayes here. Ans. 2. LDA takes into account the distribution of classes. To fix this, we can perform up-sampling or down-sampling. As machine learning makes its way into all kinds of products, systems, spaces, and experiences, we need to train a new generation of creators to harness the potential of machine learning and also to understand its implications. So, there is a high probability of misclassification of the minority label as compared to the majority label. K-Means is Unsupervised Learning, where we don’t have any Labels present, in other words, no Target Variables and thus we try to cluster the data based upon their coordinates and try to establish the nature of the cluster based on the elements filtered for that cluster. It is given that the data is spread across mean that is the data is spread across an average. If the value is positive it means there is a direct relationship between the variables and one would increase or decrease with an increase or decrease in the base variable respectively, given that all other conditions remain constant. Practice Test: Question Set - 22 1. In such a data set, accuracy score cannot be the measure of performance as it may only be predict the majority class label correctly but in this case our point of interest is to predict the minority label. Explain the process.# Explain the phrase “Curse of Dimensionality”. If the data is closely packed, then scaling post or pre-split should not make much difference. Designing a machine learning approach involves:-Choosing the type of training experience; Choosing the target function to be learned; Choosing a representation for the target function; Choosing a function approximation algorithm; All of the above Correct option is E In Predictive Modeling, LR is represented as Y = Bo + B1x1 + B2x2The value of B1 and B2 determines the strength of the correlation between features and the dependent variable. also known as Sensitivity is the ratio of true positive rate (TP), to all observations in actual class – yes. A generative model learns the different categories of data. We can only know that the training is finished by looking at the error value but it doesn’t give us optimal results. Bayes’ Theorem describes the probability of an event, based on prior knowledge of conditions that might be related to the event. models based on genetic algorithm. KNN is a Machine Learning algorithm known as a lazy learner. There should be no overlap of water saved. It automatically infers patterns and relationships in the data by creating clusters. (e.g. No, ARIMA model is not suitable for every type of time series problem. Answer: Option C 5. Machine Learning involves algorithms that learn from patterns of data and then apply it to decision making. Example: The best of Search Results will lose its virtue if the Query results do not appear fast. If we are able to map the data into higher dimensions – the higher dimension may give us a straight line. Memory is allocated during execution or runtime in Linked list. Naive Bayes assumes conditional independence, P(X|Y, Z)=P(X|Z). Now,Recall, also known as Sensitivity is the ratio of true positive rate (TP), to all observations in actual class – yesRecall = TP/(TP+FN), Precision is the ratio of positive predictive value, which measures the amount of accurate positives model predicted viz a viz number of positives it claims.Precision = TP/(TP+FP), Accuracy is the most intuitive performance measure and it is simply a ratio of correctly predicted observation to the total observations.Accuracy = (TP+TN)/(TP+FP+FN+TN).
