The reduction in free energy gives a sense of satisfaction through the release of Dopamine and motivates the brain to optimize it even further (Friston et al. 2014) by continuing the engagement. In case of online services, we realize that it is the recommendation model that provides more relevant content to the user which the brain finds closer to the predicted world model (based on prior experience of engagement) and is one of the reasons for Dopamine release. This often results in a continuous engagement with the platform, which is invariably broken at some time, due to more pressing work, alternate pursuits, distractions, fatigue, or simply wanting to get out of a rabbit hole.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b9f75c6 elementor-widget elementor-widget-text-editor\" data-id=\"b9f75c6\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>A famous experiment of neuroscience where dopamine level is monitored from the brain of rat while involving them in activities. This image in Fig.2 shows that a cue conditioned rat makes a connection between lightening of bulb with receiving of awards. Therefore, when bulb lightens, there is a spike of dopamine level in their brain which is quickly controlled by homeostasis feature of the brain. This firing gives the anticipatory pleasure, which usually happens in anticipation of good things. However, the control process brings the level down and most cases it decreases it even more than the baseline level. Therefore, this deficit in Dopamine level is the cause of craving to achieve the awards. If awards is received there is even higher spike and otherwise the level of dopamine dips even deeper than earlier. Hence, An expected reward that fails to materialize is worse than a reward that was never anticipated in the first place.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1a4a72c elementor-widget elementor-widget-text-editor\" data-id=\"1a4a72c\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The same phenomenon happens with the users who are interacting with the online platforms leveraged by time driven sessions. User who after making multiple interactions expects to receive more and more relevant recommendations, have to get off the platform for time duration greater than the threshold (because of some other work). Hence, when user returns back the recommendations got marginalized by their long term preferences because time driven session changes after in-activity at the platform. Therefore, it impacts the user experience badly and affects the CTR in long term.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-13cce26 elementor-widget elementor-widget-image\" data-id=\"13cce26\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"750\" height=\"322\" data-src=\"https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog4-768x330.png\" class=\"attachment-medium_large size-medium_large wp-image-13118 lazyload\" alt=\"\" data-srcset=\"https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog4-768x330.png 768w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog4-300x129.png 300w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog4-1024x440.png 1024w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog4.png 1110w\" data-sizes=\"(max-width: 750px) 100vw, 750px\" style=\"--smush-placeholder-width: 750px; --smush-placeholder-aspect-ratio: 750\/322;width:100%;height:42.97%;max-width:1110px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e4acd79 elementor-widget elementor-widget-text-editor\" data-id=\"e4acd79\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Technical Motivation: Each individual shows a different behavior while using online services.

In general, 30 minutes is the time period that has been extensively used to limit the length (Bernardis et al. 2022) of the break (or considered as hyperparameter but once decided is fixed for all the users). Considering a constant time period as a threshold forces any of the session-based models to summarize the user activities, even if they are heterogeneous in nature. This con- fuses the recommendation models, which expect homogeneous behavior within a session so that it can clearly capture short-term preferences and summarize them.

In the case of e-commerce, a product category is usually created when an item is placed for sale and that category can be considered for representing the item.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-13ae677 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"13ae677\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li><strong>Embedding Clustering:<\/strong><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ac9a2b0 elementor-widget elementor-widget-image\" data-id=\"ac9a2b0\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"750\" height=\"224\" data-src=\"https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog8-768x229.png\" class=\"attachment-medium_large size-medium_large wp-image-13130 lazyload\" alt=\"\" data-srcset=\"https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog8-768x229.png 768w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog8-300x90.png 300w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog8-1024x306.png 1024w, https:\/\/whiteriversmediasolutions.com\/Sony\/uvaftoap\/2025\/05\/blog8.png 1031w\" data-sizes=\"(max-width: 750px) 100vw, 750px\" style=\"--smush-placeholder-width: 750px;

Sessions are created in a way so that every single session maintains the homogeneous content at any point in time. As shown in Algorithm 1, a session continues to con- sider the items in the window while a single category of the items dominates. As the user behavior is dynamic, it keeps drifting from one category of content to another. Therefore, in the response; a new session starts right after the last occurrence of the dominating category in the ongoing session. The method ensures that each session window keeps a-like content and curates the sessions accordingly. \u00a0As shown in Algorithm, it considers the sequence of items I as input and keeps adding the items in the window (\u03a6 is a hashmap and counts the occurrences of each cate- gory) when it finds more than 2 occurrences of the same category, it is considered as dominating category, and a marker keeps monitoring index of every occurrence of this dominating category (line 3-5, algorithm.1). When it finds 2 such dominating categories, then it considers the previously set marker as the split point and starts a new session for next dominating category and then resets all the markers and hashmap.<\/span><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0b3dc89 elementor-widget elementor-widget-text-editor\" data-id=\"0b3dc89\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4><strong>4.

So when a purchase is made user suddenly changes the category of items because next need may not necessary be similar to previous need. Eg.

We proposed that a content-driven session captures the user behavior more precisely therefore it improves the recommendation performance. Content-driven sessions are created on the basis of homogeneity in the content. We proposed to cluster the items in the feature space to know a) Total number of categories available b) The category of each item. The category of each item is leveraged to decide the boundary of each session. The proposed method creates new session Id in the existing dataset and keeps the rest of the experimental setting intact. We evaluate the performance of the proposed method on four benchmark datasets on 6 session-based recommendation models. The proposed method outperformed the time-driven session on all the baseline models. This way, content-driven method a). Helps users in continuing the same experience after returning back b). Provides a solution to the problem of deciding threshold \u03b8 in TS-SBRS c). Better captures the user interaction pattern and improves the recommendation performance. The proposed method performs clustering to create labels. In domains (such as e-commerce) where the category is already known, the clustering step can be skipped.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ec362a6 elementor-widget elementor-widget-text-editor\" data-id=\"ec362a6\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>In most of the cases, it has been found that Content Driven sessions outperform the time driven sessions.
