Takeout Recommendation Dataset (TRD) from Meituan Takeout app
<p>This is a takeout recommendation dataset (TRD) which contains a vast amount of meta information from Meituan Takeout app. We collect orders from 11 commercial districts in Beijing between March 1st and March 28th, 2021. The first three weeks of orders are as training, while the last week is used for testing to avoid data leakage. We briefly summarize each file as follows and for more details, please refer to README.md.</p> <p>1. users.txt (attributes of all users)<br> 2. pois.txt (attributes of all takeout restaurants)<br> 3. spus.txt (attributes of all food)<br> 4. orders_poi_session.txt (a sequence of restaurants clicked by user before ordering)<br> 5. orders_spu_train.txt (order-food in training set)<br> 6. orders_train.txt (order-restaurant in training set)<br> 7. orders_test.txt (order-restaurant in training set)<br> 8. orders_poi_test_label.txt (test labels of order-restaurant)<br> 9. orders_spu_test_label.txt (test labels of order-food)</p> <p>10 graph.bin (graph in DGL format)</p> <p>graph.bin is build by above *.txt files, there is a vast amount of meta informarion on nodes and edges. just several codes can load this graph with 18,931,400 edges and 408,849 nodes:</p> <pre><code class="language-python">from dgl import load_graphs #should install dgl ds,_ = load_graphs("./graph.bin") g = ds[0] print(g)</code></pre> <p> </p>
Takeout gene expression is associated with temporal kin recognition
<p>A key component of parental care is avoiding killing and eating your own offspring. Many organisms commit infanticide of young but switch to parental care at the time when their own offspring would be expected, known as temporal kin recognition. It is unclear why such indirect kin recognition is so common across taxa. One possibility is that conserved mechanisms that regulate timing and feeding in other contexts are co-opted to enable the evolution of temporal kin recognition. Here we determine whether <em>takeout</em>, a gene implicated in coordinating feeding, influences temporal kin recognition in the subsocial beetle the roundneck sexton beetle, <em>Nicrophorus</em> <em>orbicollis</em>. We find that <em>takeout</em> expression is not associated with non-parental feeding changes resulting from hunger, or in the general switch to the full parental care repertoire. However, beetles that accepted and provided care to their offspring had a higher <em>takeout</em> expression than beetles that committed infanticide. Together, these data support the idea that the evolution of temporal kin recognition may be enabled by co-option of mechanisms that integrate feeding behaviour in other contexts.</p>
