To put it another way, the purpose of this is to examine the typical spending patterns of the customer, including mapping the locations of those spending, in order to differentiate between fraudulent and legitimate transactions. You have the option of using either R or Python for this project. The transaction history of the customer can serve as the data set, and you can ingest that information into decision trees, artificial neural networks, or logistic regression. You should be able to improve the overall accuracy of your system as you continue to provide it with additional data.
3. FAKE NEWS DETECTION
Fake news does not require any sort of introduction. In today’s hyper-connected world, it has become laughably simple to disseminate false information through the use of the internet. Every once in a while, you’ll notice that untrue information is being disseminated online from untrusted sources, which not only results in problems for the individuals who are being targeted but also has the potential to result in widespread panic and even physical violence.
It is essential to determine the authenticity of the information in order to put a stop to the circulation of fake news, which can be accomplished with the help of this data science project. Python, along with the packages TfidfVectorizer and PassiveAggressiveClassifier, can be utilized to construct a model that can differentiate between real and fake news. pandas, NumPy, and scikit-learn are some of the Python libraries that work particularly well with this project. You can use News.csv as the data set if you want to.
4. AN ANALYSIS OF SENTIMENT
Sentiment analysis is a tool that is supported by artificial intelligence that, in essence, enables you to identify, gather, and analyze the opinions that people have regarding a topic or a product. This type of analysis is also known as opinion mining. These viewpoints could originate from a wide variety of places, such as online reviews or responses to surveys, and they could cover a broad spectrum of feelings, including happiness, anger, positivity, love, negativity, excitement, and more.
The most data-driven modern businesses stand to gain the most from the utilization of a sentiment analysis tool because this type of software provides them with crucial information regarding the responses of the general public to a trial run of a new product launch or a shift in the company’s overall business strategy. You could construct a system similar to this one by utilizing R in conjunction with janeaustenR’s data set and the tidytext package.
5. EXPLORATORY DATA ANALYSIS
Exploratory data analysis is the first step in the analysis process (EDA). The process of helping you make sense of your data and frequently involving the visualization of those data so that you can explore them more thoroughly is an important part of the data analysis process. Histograms, scatterplots, and heat maps are just some of the options available to you when it comes to the visualization of your data. Your data may also contain unexpected results or outliers, which can be uncovered by EDA. After you have recognized the patterns and gained the necessary insights from your data, you are ready to move on to the next step
Python is an excellent choice for undertaking a task of this magnitude because it provides a number of useful packages, some of which include pandas, NumPy, seaborn, and matplotlib.
The IBM Analytics Community is an excellent resource for acquiring EDA data sets.
5. GENDER DETECTION AND AGE PREDICTION
This project, which entails determining a person’s gender and estimating their age, has been dubbed a classification problem, and it will put your abilities in machine learning and computer vision to the test. Constructing a program that can determine a person’s age and gender based on an image of them is the objective of this project.
You can use Python with the OpenCV package to implement convolutional neural networks for this project. Python is a programming language. For the purposes of this project, you can obtain the Adience dataset. It is important to keep in mind that aspects such as makeup, lighting, and facial expressions will make this task difficult and will attempt to throw off your model’s performance.
6. RECOGNIZING SPEECH EMOTIONS
Speech is one of the most fundamental ways that we can express ourselves, and it can contain a wide range of feelings, including, to name just a few examples, calmness, anger, joy, and excitement. It is possible to use the information obtained from analyzing the feelings that lie behind speech to restructure our actions, services, and even products in order to provide a more personalized service to particular individuals. This can be accomplished by conducting an analysis of the emotions that lie behind the speech.
The goal of this project is to recognize and isolate a variety of human feelings from within a variety of sound files that contain human speech. You can create something similar to this using Python by utilizing the Librosa, SoundFile, NumPy, Scikit-learn, and PyAaudio packages, respectively. You are welcome to make use of the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS), which provides access to more than 7300 individual files when developing the data set.
7. DISTRIBUTION OF CUSTOMERS INTO GROUPS
The success of modern companies depends on their ability to provide highly individualized services to their clientele, which would not be feasible in the absence of some kind of customer classification or segmentation. By doing so, businesses have an easier time orienting their services and products around their customers, which enables them to target those customers in order to generate more revenue.
For the purpose of this project, you will make use of unsupervised learning to organize your clients into different clusters according to individual characteristics such as age, gender, region, interests, and so on.
