How can patch plot with multiple patches be visualized in Bokeh?
Bokeh is a Python package that helps in data visualization. It is an open source project. Bokeh renders its plot using HTML and JavaScript. This indicates that it is useful while working with web-based dashboards.Bokeh can be easily used in conjunction with NumPy, Pandas, and other Python packages. It can be used to produce interactive plots, dashboards, and so on. It helps in communicating the quantitative insights to the audience effectively.Matplotlib and Seaborn produce static plots, whereas Bokeh produces interactive plots. This means when the user interacts with these plots, they change accordingly.Plots can be embedded as output of Flask ...
Read MoreWhat is time series with respect to Machine Learning?
Time series, as the name suggests, is data that contains certain time periods or time stamps. It contains observations over certain time period. This kind of data tells us about how variables change over time based on various factors. Time series analysing and forecasting can be used to predict data with respect to some future time.Univariate time series contains values taken with respect to a single variable at certain time instances over a period of time. A multivariate time series contains values taken with respect to multiple variables at same periodic instances of time.Time series consists of 4 components that ...
Read MoreHow can scikit-learn package be used to transform an array of specific size to a different size?
Scikit−learn, commonly known as sklearn is a library in Python that is used for the purpose of implementing machine learning algorithms. It is an open-source library hence it can be used free of cost. It is powerful and robust, since it provides a wide variety of tools to perform statistical modelling. This includes classification, regression, clustering, dimensionality reduction, and much more with the help of a powerful, and stable interface in Python. The library is built on Numpy, SciPy and Matplotlib libraries.It can be installed using the ‘pip’ command as shown below −pip install scikit−learnThis library focuses on data modelling. ...

To get the links present on the website using PowerShell, we can first retrieve the data from the webpage using the Invoke-WebRequest cmdlet.$req = Invoke-WebRequest -uri "https://theautomationcode.com" $reqOutputTo retrieve only links we can use that property and there you will also find some sub-properties like InnerHTML, Innertext, href, etc as shown in the output.$req = Invoke-WebRequest -uri "https://theautomationcode.com" $req.LinksOutputinnerHTML : Scripts innerText : Scripts outerHTML : Scripts outerText : Scripts tagName : A href : https://theautomationcode.com/scripts/ We need only links so we will use the href property.$req.Links | Select -ExpandProperty hrefOutputhttps://theautomationcode.com/2020/11/ https://theautomationcode.com/author/chiragce17/ ...
Read MoreDiameter of a Binary Tree in O(n) [A new method] in C++?
The diameter of a binary tree is the (left_height + right_height + 1) for each node. So in this method we will calculate (left_height + right_height + 1) for each node and update the result . The time complexity here stays O(n).Let us first define the struct that would represent a tree node that contains the data and its left and right node child. If this is the first node to be created then it’s a root node otherwise a child node.struct Node { int data; struct Node *leftChild, *rightChild; };Next we create our newNode(int data) function that ...
Read MoreDiagonal Traversal of Binary Tree in C++?
To consider the nodes that are passing between lines of slope -1. The diagonal traversal of the binary tree will be to traverse and print all those nodes present between these lines.Let us first define the struct that would represent a tree node that contains the data and its left and right node child. If this is the first node to be created then it’s a root node otherwise a child node.struct Node { int data; struct Node *leftChild, *rightChild; };Next we create our createNode(int data) function that takes an int value and assign it to the data ...
Read MoreConstruct Pushdown automata for L = {0(n+m)1m2n | m, n = 0} in C++
We are given with a language “L” and the task is to construct a pushdown automata for the given language which explains that the occurrences of 0’s will be the addition of occurrences of 1’s and 2’s and also, occurrence of 1 and 2 will be minimum one which can also makes the string NULL and it should be accepted by the automata.What is pushdown Automata?A pushdown automata or pushdown automaton or PDA is a technique to implement a context−free grammar in a similar way we design Deterministic Finite Automaton or DFA for a regular grammar. A DFA can operate ...
Read MoreHow to change data.table object columns value to maximum in R?
Sometimes we need to compare the maximum values or set some column of a data frame or data.table object to their maximums, especially in research studies that may require biasedness. Therefore, we can set all the column values to maximum. In case of a data.table object, we can use single square bracket to access and assign the column values to their maximum as shown in the below examples.ExampleLoading data.table package and creating a data.table object −> library(data.table) > x1 x2 DT1 DT1Outputx1 x2 1: 3 4 2: 3 5 3: 5 6 4: 10 5 5: 8 2 6: 3 ...
Read MoreHow to use mtext function to create the X-axis labels in base R?
The mtext function can help us to create X-axis or Y-axis labels and we can put these labels to places desired by us with the help of at argument. For example, if we want to use capital letters starting from A to J that are 10 characters on the X-axis labels then it can be done by using the below command −mtext(text=LETTERS[1:10],outer=FALSE,side=1,las=1,at=1:10)Example> plot(1:10,xaxt="n")OutputExample> mtext(text=LETTERS[1:10],outer=FALSE,side=1,las=1,at=1:10)Output
