    What is Data Science?

    Data science is a multidisciplinary field that leverages scientific methods, algorithms, processes, and systems to extract valuable insights from large sets of unstructured and noisy data. In addition, organizations use these actionable insights to make informed decisions.

    Alternatively, we can define data science as a process of unifying data analytics, informatics, statistics, and their related methods to understand and analyze large volumes of data, uncover hidden patterns and trends, and derive actionable insights.

    Moreover, data science is an umbrella term that involves many other subfields, such as data analytics, machine learning , computer science, and statistics. The data science process has several phases. Each phase prepares the data for the subsequent phase. These phases include data preparation, parameter tuning, and model evaluation.

    Top 10 Top Data Science Projects

    Here is a curated list of top data science projects that you can add to your portfolio and get better job opportunities. Also, we have mentioned the link for the source code of each project. So, let's start with the fake news detection project.

    1. Fake News Detection Using Python

    Fake News Detection Using Python

    We can refer fake news to false or misleading content or content whose source cannot be verified. Fake news can be generated to gain attention or damage the reputation of the targeted person. The popularity of the term fake news increased during the 2016 US President Elections. It was reported that fake news might have influenced the results of the election.

    With the help of data science, it has become possible to classify fake news or identify the authenticity of the information. To develop a fake news detection system, we can leverage machine learning algorithms, natural language processing techniques, and Python libraries, such as Numpy, Panda, and sci-kit.

    2. Detection of Forest Fire Using CNN

    Detection of Forest Fire Using CNN

    One can showcase data science expertise by developing an intelligent system that can detect forest fires or wildfires. A forest fire or wildfire is an unwanted, uncontrollable, and unexpected fire that spreads over an area of woodland or forest. It damages trees, harms wild animals, and impacts the surrounding environment.

    We can build a forest fire detection system using convolutional neural networks (CNNs) that can detect the start of a forest fire or the presence of the forest fire in an image. The primary concept of building such a data science project is to detect the forest fire from the aerial footage of the forest.

    When there is a forest fire, the system provides an alert. When we get an alert about the presence or start of a forest fire, it becomes easier to allocate the required resources to control the fire. To take the forest fire detection system to the next level, we can use climatological data to predict the common seasons or periods for wildfire.

    3. Breast Cancer Classification

    Breast Cancer Classification

    Breast cancer is a life-threatening disease, and breast cancer cases are increasing extensively day by day. The only way to combat it is to get it diagnosed at early stages and get proper treatment. We can leverage data science to develop a model that can detect breast cancer.

    We can build a breast cancer detection system using Python. To build this data science project, we need to use the Invasive Ductal Carcinoma (IDC) dataset. This dataset provides histology images for cancer-inducing malignant cells. Moreover, CNNs are best suited to develop the breast cancer detection system.

    Some popular Python libraries required to develop this system are Numpy, TensorFlow, scikit-learn, Matplotlib, Keras, and OpenCV.

    4. Sentiment Analysis

    Sentiment Analysis

    Sentiment analysis is also known as emotion AI or opinion mining. It involves the use of natural language processing (NLP), computational linguistics, and text analysis to evaluate words to determine sentiments and opinions that may be positive or negative in polarity. It is a sort of classification that can be either binary, such as optimistic or pessimistic, or multiple, such as happy, sad, angry, excited, and no response.

    Nowadays, companies use sentiment analysis to determine the likeability of their products in the market. Therefore, we can define sentiment analysis as the approach to analyzing the opinions of people on a specific product or service.

    We can develop the sentiment analysis project using the R programming language and the data set provided by the Janeausten R package. In addition, we can use general-purpose lexicons in sentiment analysis, like Bing, Loughran, and AFINN.

    5. Speech Emotion Recognition

    Speech Emotion Recognition

    Oral communication is the most effective way to communicate since it enables us to express different feelings, such as anger, happiness, passion, silence, and so on. The speech emotion recognition (SER) system recognizes emotions and affective states from speech. The best application of an SER system is at call centers.

    A call center can employ an SER system to recognize the emotions of customers to provide better customer support. We can build the speech emotion recognition system using MLPClassifier and Python packages, such as Librosa, Numpy, Scikit-learn, SoundFile, and PyAudio.

    In order to implement this system, we first need to load the data, i.e., voices that reflect various emotions, extract features from data, and divide the dataset into training and testing sets.

    Finally, we will initialize an MLPClassifier, train the model with the training dataset, and test it for accuracy with the testing dataset. For a dataset containing more than 7,300 files, we can use the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS).
