Abstract: Recently, gender equality and women’s entrepreneurship have gained considerable attention in global economic development. Prior to the design of any policy interventions to increase women’s entrepreneurship, it is significant to comprehend the factors motivating women to become entrepreneurs. The non-understanding of the factors can result in the endurance of low living standards and the design of expensive and ineffectual policies. But female involvement in entrepreneurship becomes higher in developing economies compared to developed economies. Women Entrepreneurship Index (WEI) plays a vital role in determining the factors that enable the flourishment of high potential female entrepreneurs which enhances economic welfare and contributes to the economic and social fabric of society. Therefore, it is needed to design an automated and accurate WEI prediction model to improve women’s entrepreneurship. In this view, this article develops an automated statistical analysis enabled WEI predictive (ASA-WEIP) model. The proposed ASA-WEIP technique aims to effectually determine the WEI. The proposed ASA-WEIP technique encompasses a series of sub-processes such as pre-processing, WEI prediction, and parameter optimization. For the prediction of WEI, the ASA-WEIP technique makes use of the Deep Belief Network (DBN) model, and the parameter optimization process takes place using Squirrel Search Algorithm (SSA). The performance validation of the ASA-WEIP technique was executed using the benchmark dataset from the Kaggle repository. The experimental outcomes stated the better outcomes of the ASA-WEIP technique over the other existing techniques.

1  Introduction

Entrepreneur improves the economy and people’s lives by creating jobs, exchanging ideas globally, creating technology that improves efficiency, and developing new solutions to problems. Several conditions that help entrepreneurs also help the economy as a whole provide even broader gains from supportive entrepreneurship [1]. Women entrepreneurs might be determined as women or a set of women that operate, initiate, and organize a business enterprise. Women are likely to adopt, innovate, or imitate an economic activity to be named women entrepreneurs. Women entrepreneur plays a significant role in increasing their economy [2]. Once a country doesn’t accomplish its maximum potential, the economy suffers. Fewer ‘higher potential’ female entrepreneurs result in less innovation, fewer jobs created, less export potential, and fewer ideas being realized [3,4]. By using entrepreneurial activity, higher-potential female entrepreneur increases their economic welfare, and also enhance the social fabric and economy of a society with their innovative products, job creation, services, cross-border trade, and processes. Now, the role of women’s entrepreneurship was identified in the procedure of economic growth around the world; thus, it should be promoted. Beforehand developing any policy intervention for boosting women’s entrepreneurship [5], it is significant to understand the factor driving women to be an entrepreneur. Fig. 1 showcases the statistics of Woman Entrepreneurs.

Figure 1: Statistics of Woman Entrepreneurs

The Female Entrepreneurship Index (FEI) searches for identifying the factor that enables the flourishing of higher potential female entrepreneurs—women who operate and own businesses that are export-oriented, innovative, and market expanding. With entrepreneurial activity, high-potential female entrepreneur improves their economic development and contributed to the social fabric and economy of society. A statistical test is utilized to make decisions. To implement analysis using the median, we must utilize a non-parametric test [6]. The non-parametric test is a distribution-independent test whereas the parametric test assumes that the data is a normal distribution. Parametric Test takes the mean into account whereas the Non-Parametric Test considered the median/rank to make a decision [7]. When the information doesn’t have the conventional Gaussian distribution, we should resort to the non-parametric version of the significance test. This test operates in the same way; however, they are distribution-free and require that real-valued data be initially converted into rank data beforehand the test is conducted [8]. The study presents well-developed economies, however, studies on female entrepreneurship in developing markets are scarce. Entrepreneurship is important to drive economic development, and also it is important to shedding light on the development of business by the female entrepreneur for highlighting the values that female entrepreneur brings to enhance further growth and global societies [9]. Particularly in developing economies, it is the major contributing factor to the economy and social progress, also it is an important driver for opportunities for employment and industrial competitiveness.

This article develops an automated statistical analysis-enabled WEI predictive (ASA-WEIP) model. The proposed ASA-WEIP technique mainly intends to determine the WEI. The proposed ASA-WEIP technique includes a sequence of sub-processes like pre-processing, WEI prediction, and parameter optimization. In order to predict WEI, the ASA-WEIP technique utilizes a deep belief network (DBN) model and the parameter optimization process is performed by a squirrel search algorithm (SSA). The performance validation of the ASA-WEIP technique is carried out using the benchmark dataset from the Kaggle repository.

2  Literature Review

In Etim et al. [10], an overall amount of fifty targeted female entrepreneurs in Uyo metropolis, Nigeria, have been purposefully sampled for taking part in our work. Inferential and Descriptive statistics have been adapted for interpreting the essential information. Agarwala et al. [11] highlight the current effort of governments toward presenting new financial systems to help entrepreneurship amongst women that empower them. MUDRA was the novel inventiveness towards offering financial support to women from India without some security.

Ribeiro et al. [12] explore that the entrepreneurship orientation (EO)- nexus is intermediated by the network firm established with resource acquisition, government suppliers, and agencies. Zhu et al. [13] compare women’s entrepreneurship in China and Vietnam by exploring the problem, motivation, and success factors associated with women-owned businesses.

Anggadwita et al. [14] analyze the effect of social perceptions, entrepreneurial orientation, and socio-cultural environment on women’s entrepreneurial intention. The structural equation modeling method is utilized as an analytical method including 400 women entrepreneurs in micro small and medium-sized enterprises (MSME) in Indonesia. The outcomes show that the social perceptions and socio-cultural environment have significant and positive effects on entrepreneurial orientation. Bouzari et al. [15] purposes for examining the effects of online social media on women’s entrepreneurship in comparative research. The statistical population of current research comprises women entrepreneurs active in the domain of online business in Iran and Hungary. ANOVA test has been utilized for examining the parameter of online social networks in distinct environments.

Ingalagi et al. [16] discuss the factors influencing and their impact on satisfaction and firm performance. The presented method and hypothesis were tested by the information collected from beauty parlors, boutiques, retail shops, and carpet manufacturers in Karnataka, India. Data analysis has been performed by bivariate, multivariate, and univariate technologies. In Structural Equation Modelling (SEM), paths have been made to evaluate the cause-and-effect relationships among distinct factors are psychological, social, resource factors, and financial and entrepreneurial satisfaction and performance. Wu et al. [17], proposed a competitive DBN for learning features with more discriminatory data from labeled and unlabeled samples. The presented method comprises four phases: a typical Restricted Boltzmann Machine (RBM) is pre-trained with a massive amount of unlabeled information for initializing its parameter; the hidden unit is grouped based on the category which offers a clustering method for competitive learning; back-propagation and competitive training approaches are utilized for updating the parameter to achieve the clustering task; and apply supervised fine-tuning and layer-wise training, a Deep Neural Networks (DNN) is constructed to attain feature.

3  The Proposed Model

In this study, a new ASA-WEIP approach was developed for the prediction of WEI. The proposed model follows a three-stage process. Initially, the input data is pre-processed for the conversion of original data into a useful format. Secondly, the DBN model is applied for the effectual prediction of WEI. Thirdly, the SSA has been utilized to fine-tune the hyperparameters of the DBN model. The detailed work of each module is offered in the succeeding sections.

3.1 Data Pre-Processing

Primarily, the input data is pre-processed to transform the actual input data into a useful format. The Z-score is computed utilizing the standard deviation (SD) and the arithmetic mean of provided WS data has often been utilized as a score normalization approach. It can be predicted that this normalized method is achieving well whether prior data on the average score and score differences of the matcher. The normalizing scores are provided as:

sk′=sk−μσ (1)

In which, σ implies the SD and μ stands for the arithmetic mean of the provided information. During this case, the normalized of smoothed data has been completed by Z-score normalized.

3.2 WEI Prediction Using DBN Model

At the time of WEI prediction, the DBN model receives the pre-processed data and thereby predicts the values of WEI. DBN is a multilayer probabilistic generation method that is learned for extracting a deep hierarchical depiction of trained data. The DBN is collected from many layers of RBM and classified additional to the topmost layer [18]. The RBM has an energy-based generative method which comprises a layer of visible nodes (v1,v2,…,vj,…,vm) demonstrating the data and layer of hidden node (h1,h2,…,hj,…,hn) learning for representing features, with all vi∈{0,1} and hj∈{0,1} . It can be determined that the bias of the visible node is (b1,b2,…,bi,…,bm) , and the bias of hidden node is (c1,c2,…,cj,…,cn) .

E(v,h)=−∑i=1m⁡bivi−∑j=1n⁡cjhj−∑j=1n⁡∑i=1m⁡viwijhj. (2)

As stated by the energy function E(v,h) , the joint likelihood distribution to hidden and visible layers is demonstrated as:

P(v,h)=1Zexp(−E(v,h)), (3)

In which, Z refers to the partition function that is the sum of entire feasible pairs of hidden and visible layers.

Z=∑v⁡∑h⁡exp(−E(v,h)) (4)

The probability allocated to visible vector v has been provided by adding feasible binary hidden vector h , in the following:

P(v)=∑h⁡P(v,h)=1Z∑h⁡exp(−E(v,h)) (5)

When there are no direct links among the similar layers in RBM, this hidden unit is independently offered to the visible unit [19]. Thus, the visible vector v, the conditional likelihood of hidden vector h is represented as follows:

P(v)=∏j=1nP(v). (6)

Likewise, in the hidden layer h, the conditional likelihood of visible layer v is represented as follows:

P(h)=∏i=1mP(h). (7)

In the visible layer v, the activation state of all the hidden units is conditionally independent. Now, hj∈{0,1} , and activation possibility of the jth hidden unit was given by:

P(v)=Sigm(∑i=1mwijvi+cj), (8)

Whereas Sigm(x)=11+e−x denotes the logistic sigmoid function. Fig. 2 illustrates the DBN structure.

Figure 2: DBN structure

Therefore, the activation possibility of the visible layer is conditionally independent once given a hidden layer h :

P(h)=Sigm(∑j=1nwijhj+bi). (9)

When the RBM was trained, the network energy is reduced, and the possibility in Eq. (5) is maximized. For maximizing the log -the probability of (v) , its gradient regarding the network parameter θ is estimated by:

∂logP(v)∂θ=−EP(v)[∂E(v,h)∂θ]+EP(v′,h′)[∂E(v′,h′)∂θ] (10)

Whereas E represents the expectation operator. CD-k approach approximates the expectancy in Eq. (10) by constraint k (often k=1 ) iteration of Gibbs sampling to upgrade the network parameter θ=(iV,b,c) . The upgrade method of variable θ is given by:

∂logP(v)∂wij=P(v)⋅vi−∑v′P(v′)P(v′)⋅vi′, (11)

∂logP(v)∂bi=vi−∑v′P(v′)⋅vi′, (12)

∂logP(v)∂cj=P(v)−∑v′P(v′)P(v′). (13)

Afterward, an RBM was trained; another RBM is stacked on the topmost one. Hence, various layers of RBM are stacked for extracting distinct features that denote complicated structures in the information. Once the DBN has been trained, the network parameter θ=(W,b,c) is utilized for initializing the weight of multilayer FFNN. The backpropagation model is utilized for finetuning the network parameter θ=(W,b,c) for improving the detection accuracy of the NN.

3.3 Parameter Optimization Using SSA

For boosting the predictive outcomes of the DBN technique, the SSA is utilized and thereby enhances the overall performance. The hunting process begins if flying squirrels start scavenging. Simultaneously, it can alter its regions and examine several areas of wood. While the climatic states are appropriately hot, it can meet its daily vitality requires further quickly on eating routine of oak seeds tree (OST) available from bounty and therefore, it is devouring OST rapidly afterward determining them. The ability of hickory nuts is for helping from maintaining its vitality prerequisites from harsh climates reduce the costly search excursion and enhance the probability of endurance [20–24]. Concerning the finishing of wintertime, squirrels again developed a dynamic. It can be a monotonous process and infrastructure for the establishment of SSA. Fig. 3 depicts the flowchart of SSA. The purpose of employing SSA in optimizing the parameter is its efficiency in determining solutions for the unimodal, multimodal optimization functions.

Figure 3: Flowchart of SSA

Considering the count of squirrels is N, and the upper as well as lower limits of detection space, are XU and XL , the N squirrels are randomly generated as:

Xi=XL+rand(1,D)×(XU−XL) (14)

In which Xi represents the ith squirrel, (i=1:N) , rand() signifies the arbitrary number from the range of zero and one, and D stands for the measurement of the problem. Amongst the N trees, have one hickory tree (HT) and Na OST, but the rests are classical trees taking no food. The HT is an optimum food asset to the squirrels but the OST arises the second. The locate the fitness estimates of the populace from increasing requests, the squirrel is divided into 3 classes:

•   Squirrels placed at HT (Wh) ;

•   Squirrels located in ordinary trees (Wn)

•   Squirrels located at OST (Wa)

The squirrel refreshes its conditions by skimming to HT or OST as follows:

Xit+1={Xit+dgGc(Xait−Xit)ifr2≥PdpRandomlocationotherwise (15)

Xit+1={xit+dgGc(Xht−Xit)ifr3≥PdpRandomlocation,otherwise (16)

Pdp is valued at 0.1 and denotes the chaser possibility. During the case that r>Pdp , no chasers appear, and the squirrel coast from the backwoods for discovering the food and is protecting. When r<Pdp , the chaser appears, and the squirrel is compelled for limiting the degree of exercise and is imperiled, and its places are transferred arbitrarily. dg refers to the skimming separation which is expressed as:

dg=hgtan(ϕ) (17)

In which, hg refers to the constant evaluated by 8, tan(ϕ) signifies the coasting point which is represented as:

tan(ϕ)=DL (18)

The drag power and lift power are evaluated as:

D=12ρV2SCD (19)

L=12ρV2SCL (20)

To start all generations, the SSA requires that the whole populace is in winter which represents that the places of every squirrel were upgraded [22–24]. At this point, once the squirrel is refreshed, anyway the season, altered has been decided by a subsequent equation:

Sct=∑k=1d(Xai,kt−Xhkt)2i=1,2,…,Na (21)

Smin=10e−6365t/(Tmax/2.5) (22)

If Stc<Smin , winter has ended and the season drives to summer, then the season has been unchanged. But the squirrels skimming to Wa and not gathering with chaser move its states as follows:

Xinewt+1=XL+Le′vy(x)×(XU−XL) (23)

The levy is the arbitrary walk method whose progression observes with Levy appropriation and is demonstrated as:

Le′vy(x)=0.01×α×ra|rb|1β (24)

where α is defined as:

α=[Γ(1+β)×sinsin(πβ2)Γ(1+β2)×β×2(β−12)]1β (25)
