        The article is based on a set of data consisting of specific data obtained from user
reviews posted on Holidayiq.com about different types of attractions in India [
        <xref ref-type="bibr" rid="ref1 ref2">1-2</xref>

This dataset is completed with feedback on appointments published by 249
Holidayiq.com reviewers by March 2020.

      <p>This paper discusses and compares some machine-learning regression methods for
developing a prognostic model that predicts the daily number of visitors in different
areas (tourist places) of India.</p>
      <p>
        Implementation of strategic projects will allow for appropriate restructuring of the
tourism industry in relation to the socio-economic life of the state [
        <xref ref-type="bibr" rid="ref3 ref4 ref5 ref6 ref7 ref8 ref9">3-9</xref>
        ]. It is focus on
population, government, management and business structures and a comprehensive
approach to ensuring the effective use of benefits and opportunities of domestic
tourism sector due to climatic conditions and historical features [

        ], taking into
account the requirements of environmental protection and preservation and enrichment
of is heritage [

      <p>
        Tourism in India is important for the country's economy and growing rapidly [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. The
World Travel and Tourism Council estimated that tourism in 2018 generated ($ 240
billion) or 9.2% of India's GDP and supported 42.673 million jobs, 8.1% of total
employment [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. It is projected that by 2028 this sector will grow from 6.9% to 32.05
GEL [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Tourism is one of the largest earners in foreign currency. The importance of
tourism as a tool for economic development and employment, especially in remote
and backward areas, has well recognized around the world. The benefits of tourism
can be increased either by increasing the number of tourists or by increasing the
length of stay of tourists in the country. Data on national length of stay are very
important and useful for the purposeful promotion of tourism in the outgoing markets.
      </p>
      <p>
        This paper uses a set of user data (feedback) on different types of attractions in
India. The dataset contains 1743 data points collected from Holidayiq.com [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ].
      </p>
      <p>The main features of the selected data set:
1. User ID;
2. Number of inspections of stadiums, sports complexes;
3. Number of reviews of religious institutions;
4. Number of reviews about the beach, lake, river, etc .;
5. The number of reviews about theaters, exhibitions;
6. The number of reviews about shopping centers, shopping malls;
7. Number of reviews about parks, picnic areas, etc.</p>
      <p>The method that will implemented in this work is the classification tree.</p>
      <p>
        To implement this course work, we chose the Python programming language.
Python is an easy-to-use yet full-fledged programming language that provides much
more tools for structuring and supporting large applications [
        <xref ref-type="bibr" rid="ref26 ref27 ref28 ref29 ref30 ref31 ref32">26-32</xref>
        ].
      </p>
      <p>
        The large selection of libraries is one of the main reasons that Python is the most
popular programming language used for ML [
        <xref ref-type="bibr" rid="ref33 ref34 ref35 ref36 ref37 ref38 ref39 ref40 ref41 ref42 ref43 ref44 ref45">33-45</xref>
        ]. A library is a module or group
of modules published from various sources, such as PyPi, that contains a pre-written
piece of code that allows users to achieve certain functionality or perform various
actions [
        <xref ref-type="bibr" rid="ref46 ref47 ref48 ref49 ref50 ref51">46-51</xref>
        ]. Python libraries provide basic-level elements, so you do not need to
encode them from the beginning. ML requires constant data processing, and Python
libraries allow you to access, process, and transform data [
        <xref ref-type="bibr" rid="ref52 ref53 ref54 ref55 ref56 ref57 ref58 ref59 ref60 ref61">52-61</xref>
        ].
First, we need to connect libraries to use their capabilities in the future
After downloading the data, reading our data set, and building graphs. Next, we want
to show you a chart that visualizes data according to user feedback about picnics and
parks. As we see here, we have 2 local highs and 4 local lows. The same can be said
for the next 2 graphs. These graphs determine whether to work with this data and
allow you to determine whether to normalize it or not.
      </p>
      <p>The following graph is also a chart, but it shows how feedback after visiting the
theater affects the feedback of beaches, lakes, and we can see points from 0 to 10 here.</p>
      <p>The following graph is a scatter graph that shows us the distribution of attribute data
relative to the data distribution of another attribute. We need this data in order to
cluster it in the future.</p>
    </sec>
    <sec id="sec-3">
      <title>Assigning Target and Feature Variables</title>
      <p>Feature selection is one of the core concept in order to affect the performance of the
model. In the piece of code shown above, we have assigned the feature and target
variables.</p>
    </sec>
    <sec id="sec-4">
      <title>Splitting the Dataset into Training Set and Testing Set</title>
      <p>We generally split the data we have into training and testing sets so that our model
learns on this data. we use the test data to test how accurate our model is.

Here we have to divide our data as 70% training and 30% testing.</p>

      <title>Data Visualization</title>
      <p>The entropy for each node in the decision tree is calculated and shown in the Fig. 9.
In machine learning, the perceptron is an algorithm for the controlled study of binary
classifiers. A binary classifier is a function that can determine whether an input
represented by a vector of numbers belongs to a particular class.</p>
    </sec>
    <sec id="sec-8">
      <title>Results</title>
      <p>Decision tree: 44%. Perceptron: 10%. Logistic regression: 8%. Note: Since the dataset
is small, we are getting low accuracy. Conclusion from the above results we can
conclude that decision tree is the best method for this dataset with an accuracy of 44%.</p>

      <title>Conclusions</title>
      <p>This article discusses and compares some machine-learning regression methods for
developing a prognostic model that predicts the daily number of visitors in different
areas (tourist places) of India. Visitor reviews from holidayiq.com are used as data.
The main features of the selected data set are described. Next, methods and means of
implementation are described. To implement this course work, we chose the Python
programming language. After downloading the data, reading our data set, and
building graphs. This article demonstrates 6 graphs, namely 4 bar charts and two scatter
plots. Three machine-learning methods are used. The first was the decision tree,
which showed the best result of 44%. The second is the 10% perceptron, and the third
is the logistic regression method. Because the sample of my dataset is small, that is
why we got such accuracy of algorithms. In general, we can say that the algorithms
are not very successful in their task, but this is because the data sample is too small.</p>
