HAR features impacts

write literature on HAR, various features from the data set (the data sets often consisting of raw accelerometer data together with some participant demographic data) .
1- features can be used directly
2- constructed features.
Focusing on recent literature, what kinds of features are generally used, and what justification/evaluation do authors provide for using them, Ideally, you should give an overview of both the
1- important categories of features
2- the feature selection methods used.
the paper will have
abstract
I. introduction that introduces the need of features extraction and selection in Human activity recognition
II. Features are divided into several representation domains
1- features can be used directly
2- definition , 2-main features – 3-technology, algorithms, methodology do they use to use these 4- results5- strength and weaknesses of these features and the reasons

3- constructed features.

Time-domain features
Frequency-domain features
Wavelet transforming
deep learning feature
in each type you will talk about 1-definition, 2-main features – 3-technology, algorithms, methodology do they use to extract these features 4- results5- strength and weaknesses of these features and the reasons
including general Diagrams and tables that summary the main ideas group each type of features extractions (not from the papers

III. features selection in Human activity recognition
(in each way of selection you will talk about – 1-technology, algorithms, methodology do they use to select 2- data 3- results4- strength and weaknesses of these features and the reasons
including general Diagrams and tables that summary the main ideas group each type of features selection (not from the papers)
V. Dissection
based on the research, to what extent are the features chosen based upon preexisting work in the literature, and to what extent is it based on empirical evaluation? In your survey of the literature, find category of feature or feature selection technique which might be useful in further experiments
VI. conclusion
