What is feature Engineering why this is used mention some techniques of feature engineering?

What is Feature Engineering for Machine Learning? Feature engineering is the ‘art’ of formulating useful features from existing data following the target to be learned and the machine learning model used. It involves transforming data to forms that better relate to the underlying target to be learned.

What is feature selection for machine learning?

Feature selection is the process of reducing the number of input variables when developing a predictive model. It is desirable to reduce the number of input variables to both reduce the computational cost of modeling and, in some cases, to improve the performance of the model.

Why do we need feature selection in machine learning?

Top reasons to use feature selection are: It enables the machine learning algorithm to train faster. It reduces the complexity of a model and makes it easier to interpret. It improves the accuracy of a model if the right subset is chosen.

What are the current research topics in machine learning?

Here is the list of current research and thesis topics in Machine Learning: Machine Learning Algorithms. Computer Vision. Supervised Machine Learning. Unsupervised Machine Learning. Deep Learning. Neural Networks. Reinforcement Learning. Predictive Learning. Bayesian Network. Data Mining. Machine Learning Algorithms

What is feature engineering and why is it important?

If feature engineering is done correctly, it increases the predictive power of machine learning algorithms by creating features from raw data that help facilitate the machine learning process. Feature Engineering is an art. Watch the below video for complete understanding.

What are some of the best machine learning projects for students?

One of the best ideas to start experimenting you hands-on Machine Learning projects for students is working on Iris Flowers classification ML project. Iris flowers dataset is one of the best datasets for classification tasks. Since iris flowers are of varied species, they can be distinguished based on the length of sepals and petals.

What are some hot topics for MTech thesis and project?

It is another hot topic for M.Tech thesis and project along with machine learning. Deep Neural Network is a type of Artificial Neural Network with multiple layers which are hidden between the input layer and the output layer. This concept is known as feature hierarchy and it tends to increase the complexity and abstraction of data.
