Exploratory Data Analysis on Iris Dataset
IntroductionIn Machine Learning and Data Science Exploratory Data Analysis is the process of examining a data set and summarizing its main characteristics about it. It may include visual methods to better represent those characteristics or have a general understanding of the dataset. It is a very essential step in a Data Science lifecycle, often consuming a certain time.In this article, we are going to see some of the characteristics of the Iris dataset through Exploratory Data Analysis. The Iris Dataset The Iris Dataset is very simple often referred to as the Hello World. The dataset has 4 features of three ...
Read MoreRole of Log Odds in Logistic Regression
Introduction Logistic Regression is a statistical method to predict a dependent data variable based on the relationship between one or more independent variables. It makes use of log odds and with the help of a logistic function, it predicts the probability of an event occurring. It is a classification method. What are Log Odds and Why are they Useful for Logistic Regression? Logistic regression is used to predict binary outcomes. For example, in an election, whether a candidate will win or not, whether SMS is spam or ham, etc. Odds are the ratio of the probability of success to failure. ...
Read MoreTop 7 Clustering Algorithms Data Scientists Should Know?
Clustering algorithms are a type of machine learning algorithm that can be used to find groups of similar data points in a dataset. These algorithms are useful for a variety of applications, such as data compression, anomaly detection, and topic modeling. In some cases, clustering algorithms can be used to find hidden patterns or relationships in a dataset that might not be immediately apparent. By grouping similar data points together, clustering algorithms can help to simplify and make sense of large and complex datasets. In this post, we will look closely at Clustering algorithms and the top seven algorithms that ...
Read MoreDifference between Simplex, Half duplex and Full Duplex Transmission Modes
In communication systems, the data transfer between a sender and a receiver follows a particular mode which is also known as the "transmission mode". On the basis of the nature of data sent and received, we can categorize the Transmission modes as Simplex, Half−duplex, and Full−duplex. Read this article to find out more about these transmission modes and what sets them apart. Simplex Mode of Data Transmission In a data communication network, when there is a single movement of data or one control movement of data from the sender to the receiver, then it is called the Simplex mode of ...
Read MoreDifference between Sequence Diagram and Activity Diagram
Both sequence diagrams and activity diagrams are commonly used in software engineering to model the interactions and flows within a system. They are also useful in other fields, such as business process modeling, to model and analyze the flow of activities or interactions within a business process. Read this article to find out more about sequence diagrams and activity diagrams and how they are different from each other. What is Sequence Diagram? A sequence diagram is a diagram in that is used in representing the sequence of messages flowing from one object to another. The main objective of a sequence ...
Read MoreDifference Between Data Warehouse and Data Mart
Both data warehouses and data marts serve the same purpose; they are data repositories. However, we can differentiate a data warehouse from a data mart on the basis of the amount of data they can store. A data warehouse a large repository of data that is collected from different organizations, whereas a data mart is a logical subset of a data warehouse. Read this article to find out more about data warehouses and data marts and how they are different from each other. Let's start with a basic overview of the two. What is a Data Warehouse? Data Warehouse is ...

Read MoreHow to convert a .wav file to a spectrogram in Python3?
To convert a .wav file to a spectrogram in python3, we can take the following steps −Load a .wav file from local machine.Compute a spectrogram with consecutive Fourier transforms using spectrogram() method.Create a pseudocolor plot with a non-regular rectangular grid using pcolormesh() method.Use imshow() method with spectrogram.To display the figure, use show() method.Exampleimport matplotlib.pyplot as plt from scipy import signal from scipy.io import wavfile plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True sample_rate, samples = wavfile.read('test.wav') frequencies, times, spectrogram = signal.spectrogram(samples, sample_rate) plt.pcolormesh(times, frequencies, spectrogram, shading='flat') plt.imshow(spectrogram) plt.show()Output
