Online Grocery Recommendation Using Machine Learning Github – Online shopping is one of the greatest benefits available through technology. Everyone has access to billions of products with a single touch. A few clicks and a little patience… and the product is in your hands. Nowadays it is also possible to order groceries and vegetables online. Online shopping will only expand due to the social distancing introduced by COVID-19.
With customers’ increasing reliance on online shopping, we strive to make the customer experience seamless and personalized with product recommendations.

This project aims to build a food recommendation system that will provide customers with suggestions on relevant products to buy next. In this project we used collaborative filtering of the instacart dataset.

Collaboration here means working with different users. We find similarities between users to help them recommend products. Given a query user, we try to find other users who have similar purchasing behavior as the query user. We recommend inquiring users products that have been purchased by similar users. Because this collaboration occurs between users, it’s known as user-to-user collaboration filtering. A similar type of collaboration can occur between items or products.
Where tf(item,user)=how many times a user buys an item, U=total number of users, N=total number of users and DF=number of users who bought a specific item.
The disadvantage of this system is that we have no ground truth. A large number of products are available. It is very likely that the product recommended by the system was not purchased by the user. However, a similar item may have been purchased. Therefore, we used the average recall value for all users to score our model.
In addition, we also implemented K-Means clustering to find similar users and a popularity-based method to recommend products to a new user.

Due to the ongoing pandemic situation and recent technological advances, the reliance on online services has increased significantly. One benefit of food recommendation systems is that people tend to buy groceries on a regular basis. Using a user’s purchase history can prove very beneficial for any online grocery store.
This project was developed as part of a machine learning course led by Dr. Tanmoy Chakrobarty and our TAs.

Whether and which measures politicians should take to promote healthier, more sustainable and more ethical food choices is a matter of controversy. Policies often suffer from a lack of data. This is especially true in the growing space of online grocery shopping. However, it is not always possible to test the impact of all possible policy interventions in this area. Computer-simulated shopping experiments offer a supplementary approach here. Recent evidence suggests that they increase the realism of consumer experiments and collect valid data at a relatively low cost. In this article, we present an open-source toolkit that offers multiple ways to design and run experiments in the context of online grocery shopping. It therefore supports researchers and policy makers in evaluating in-store interventions to encourage more sustainable food choices.
Currently, more and more governments, NGOs and food industry stakeholders are following the call of the United Nations to move towards a healthier and more sustainable food system [1]. Empirical evidence, particularly in western countries, emphasizes the negative impact of prevailing dietary habits on individual, environmental and societal health [2]. Therefore, policy measures that are limited to the supply side do not appear to be sufficient to trigger a sustainable transition of the food system [3]. As a result, there is controversy over which public and private institutions should or should not promote “better dietary choices” [4, 5].
Continuous Delivery For Machine Learning
Even today, most food decisions are still made in traditional brick-and-mortar supermarkets. However, driven by the development and spread of new communication technologies, grocery shopping is undergoing a change in the 21st century [6]. As one of the main elements of this transformation, online grocery shopping is becoming an increasingly important commerce channel, especially in metropolitan areas [7]. Therefore, in-store interventions in brick-and-mortar stores and online supermarkets are important tools for policymakers aiming to change consumer choices towards sustainable food [8]. In doing so, they can resort to a number of different types of interventions, ranging from economic interventions (e.g. taxes) to changes in the microenvironment of the craft (e.g. architectural selection techniques; see [9] for an overview).
Given this diversity, evidence-based policy making requires constant data to identify the right type of intervention or combination of interventions for a given case. For example, due to a lack of empirical evidence, the effectiveness of changes in the retail microenvironment to promote sustainable food choices is still questioned [10,11]. In addition, little is known about the extent to which findings from traditional brick-and-mortar retail can be transferred to online supermarkets [7, 12]. For example, there is early evidence that online supermarkets should not be viewed as perfect mirrors of their real-world equivalents. While some elements of the shopping environment, such as shelf placement strategies, seem to be a relevant factor for both online and offline supermarkets [13, 14], both channels differ in aspects such as (i) product presentation, e.g. physical vs. virtual [15], (ii) navigation paths [16] or interpersonal interactions [17, 18]. Furthermore, compared to physical contexts, online environments allow for easier, faster, and more flexible integration of different designs and interventions, and offer advanced features such as decision support systems [19].
Therefore, as part of the transition to a sustainable food system, it is imperative to gain further insights into the determinants of in-store consumer behavior and food choices in online supermarkets and traditional brick-and-mortar stores. As one of the first survey studies in Poland, it analyzed the determinants and barriers of ecological online shopping [20]. Only then is it possible to evaluate current legal requirements (e.g. packaging instructions) for their effectiveness in the analogue and digital environment and to modify them if necessary. Nevertheless, empirical knowledge can support policy makers in developing, testing and adopting new strategies to manage sustainable food choices [21, 22, 23].
Since it is not always possible to conduct studies in real (online) supermarkets, researchers have recently started to conduct studies in simulated virtual supermarkets [24, 25, 26]. Such an approach has the potential to increase the realism of consumer experiments and allow researchers to collect valid purchase data at relatively low cost.

To make computer-simulated shopping experiments as accessible as possible for interested researchers, we developed an open source, modular, and highly customizable online virtual supermarket application called VOS. The application enables researchers to easily implement and conduct experiments as part of (online) grocery shopping. It can therefore assist in the development and evaluation of policies aimed at promoting more sustainable food choices. All you need is a server computer (e.g. a cloud server) to host the experiment and participants with access to the device via a modern web browser.
The front-end of the tool is designed to mimic the design and store features (such as navigation tools) of a realistic online grocery store environment. In addition, the back-end of the tool allows researchers to modify research conditions and configure and implement various experimental treatments.
