Take a look, feat['CPI'] = feat['CPI'].fillna(mean(feat['CPI'])), new_data = pd.merge(feat, data, on=['Store','Date','IsHoliday'], how='inner'), # merging(adding) all stores info with new training data, store_type = pd.concat([stores['Type'], stores['Size']], axis=1), store_sale = pd.concat([stores['Type'], data['Weekly_Sales']], axis=1), # total count of sales on holidays and non holidays, # Plotting correlation between all important features, from sklearn.preprocessing import StandardScaler, from sklearn.metrics import mean_absolute_error, from sklearn.tree import DecisionTreeRegressor, xgb_clf = XGBRegressor(objective='reg:linear', nthread= 4, n_estimators= 500, max_depth= 6, learning_rate= 0.5), from sklearn.ensemble import ExtraTreesRegressor, x.field_names = ["Model", "MAE", "RMSE", "Accuracy"], x.add_row(["Linear Regression (Baseline)", 14566, 21767, 8.89]), final = (etr_pred + xgb_clf_pred + rfr_pred + dt_pred)/4.0, 3 Data Problems You Might Not Even Know You Have (and How to Fix Them). The data would also major on sales-to-employee ratio. I had access to three different data sets from Kaggle.com about the company. The number of features that can be split on at each node is limited to some percentage of the total (which is known as the hyperparameter), accuracy RandomForestRegressor: 96.56933672047487 %. As we have few NaN for CPI and Unemployment, therefore we fill the missing values with their respective column mean. Range from 1â45.- Type: Three types of stores âAâ, âBâ or âCâ.- Size: Sets the size of a Store would be calculated by the no. dplyrâs roots are in an earlier package called plyr , which implements theâsplit-apply-combineâ strategy for data analysis(PDF). Forecasting 2012 holiday sales of Wal-mart with SAS Enterprise Miner using data obtained from kaggle.com. We are going to use different models to test the accuracy and will finally train the whole data to check the score against kaggle competition. The term âheat mapâ was originally coined and trademarked by software designer Cormac Kinney in 1991, to describe a 2D display depicting financial market information, though similar plots such as shading matrices have existed for over a century. Input (2) Output Execution Info Log Comments (9) In this post, you will discover a suite of challenging time series forecasting problems. If that gap is reduced then also performance can be improved. > test1 <- read.csv(â~/features.csvâ,header = TRUE, check.names = TRUE), > pre_final_df <- merge(stores_df,sales_df,by=c(âStoreâ)), > final_df <- merge(pre_final_df,features_df,by=c(âStoreâ,âDateâ,âIsHolidayâ)). Sales for this ready-to-eat pastry increased seven times the normal rate before a hurricane. Each bucket defines an numerical interval. As a predictive analysis, the multiple linear regression is used to explain the relationship between one continuous dependent variable and two or more independent variables. For example, alert automatically converts any value to a string to show it. And Walmart is the best example to work with as a beginner as it has the most retail data set. Note that just taking top models doesn’t mean they are not overfitting. The n top models are decided by their accuracy and rmse. The Extra-Tree method (standing for extremely randomized trees) was proposed with the main objective of further randomizing tree building in the context of numerical input features, where the choice of the optimal cut-point is responsible for a large proportion of the variance of the induced tree. In this scenario, the sales team is the dependent variable and your goal is to understand what influences it. 2.

The dataset includes special occasions i.e Christmas, pre-Christmas, black Friday, Labour day, etc. Because making accurate predictions for each product on single days is almost impossible, this project will optimize the accuracy by all means for daily sales prediction. accuracy XGBRegressor: 97.21754267971075 %. > corrplot(res, type = âupperâ, order = âhclustâ, tl.col = âblackâ, tl.srt = 45). Data preprocessing is a data mining technique that involves transforming raw data into an understandable format. This application will help in providing us with the data on future sales, and hence we can improve the sales of the company. Walmart Sales Forecasting Data Science Project. The Walmart challenge: Modelling weekly sales. The topmost decision node in a tree which corresponds to the best predictor called root node. With respect to random forests, the method drops the idea of using bootstrap copies of the learning sample, and instead of trying to find an optimal cut-point for each one of the K randomly chosen features at each node, it selects a cut-point at random. The Spearman rank correlation test does not carry any assumptions about the distribution of the data and is the appropriate correlation analysis when the variables are measured on a scale that is at least ordinal. Data preprocessing is used database-driven applications such as customer relationship management and rule-based applications (like neural networks). Usually, in statistics, we measure four types of correlations: Pearson correlation, Kendall rank correlation and Spearman correlation. Predicting future sales for a company is one of the most important aspects of strategic planning. That is, multiple linear regression analysis helps us to understand how much will the dependent variable change when we change the independent variables. In our daily life, we are using a weather forecast and plan our day activity accordingly. When the gamma and beta values are set between 0 and 1, the values close to 0 specifies that weight is placed on the most recent observation while constructing the forecast of future values. The final result is a tree with decision nodes and leaf nodes. By looking at the new car sales timeline and new car sales by month below, you can see that sales have increased significantly over the last couple years. Predicting future sales for a company is one of the most important aspects of strategic planning. Final Project Report - Walmart Sales 1. Forecasting is used to predict future conditions and making plans accordingly. Type: Three types of stores ‘A’, ‘B’ or ‘C’.Size: Sets the size of a Store would be calculated by the no. The graph below will give you an idea about correlation. 6. Machine learning methods have a lot to offer for time series forecasting problems. Total we have 421570 values for training and 115064 for testing as part of the competition. See Walmart Inc. (WMT) stock analyst estimates, including earnings and revenue, EPS, upgrades and downgrades. Correlation can help in predicting one quantity from another, Correlation can (but often does not, as we will see in some examples below) indicate the presence of a causal relationship, Correlation is used as a basic quantity and foundation for many other modeling techniques. Now letâs run the linear regression model to forecast Toyota Auris sales for 2018 and 2019 and sort by demand. The direction of the relationship is indicated by the sign of the coefficient; a + sign indicates a positive relationship and a â sign indicates a negative relationship. Sales forecasting It is important to note that we also have external data available like CPI, Unemployment Rate and Fuel Prices in the region of each store which, hopefully, helps us to make a more detailed analysis. As the data is Time-Series we sort them in ascending order so that the model can perform on the historical data. x9 and obtain a value for weekly sales: >y=a+XTemperature*41.17+XFuel_Price*2.562+XMarkDown1*16305.11+XMarkDown2*3551.41+XMarkDown3*16.16+XMarkDown4*3611.60+XMarkDown5*1240.2+XCPI*220.806+XUnemployment*7.931, # WEEKLY SALES FOR SUCH A CONDITION WILL BE, 17707.02 <- Final Weekly Sales Value ( Weekly Sales â described more in Dataset explanation in Section 2.2), Gain Access to Expert View â Subscribe to DDI Intel, In each issue we share the best stories from the Data-Driven Investor's expert community.Â Take a look. > col<- colorRampPalette(c(âblueâ, âwhiteâ, âredâ))(20), > heatmap(x = res, col = col, symm = TRUE ). of products available in the particular store ranging from 34,000 to 210,000. The data collected ranges from 2010 to 2012, where 45 Walmart stores across the country were included in this analysis.
