Are there any advantages of using survival analysis models like Cox’s proportional hazard model with uncensored data over simple linear regression or other classic ML models? I have data with recurrent events and I try to predict the time of the next event. Data contains about 2000 different subjects and about 60 events per subject. The percentage of censored data (the last event of each subject) is small, and I don't think it plays a big role in the prediction.

I used the Query Monitor plugin to find slow query on my WordPress site. The below-mentioned WP_Query->get_posts() takes about 0.3446 query time out of the total Database Query time of 0.3976. SELECT wp_posts.ID FROM wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) WHERE 1=1 AND wp_posts.ID NOT IN (203598) AND ( wp_term_relationships.term_taxonomy_id IN (17) OR wp_term_relationships.term_taxonomy_id IN (11652,20693,21952,23971,24907,24908,25928) ) AND wp_posts.post_type = 'post' AND ((wp_posts.post_status = 'publish')) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 6 I'm guessing it …

So I plan on making a mobile app that will let students predict their final grades based on their mock exam results. I can train my model with previous years results. X: 5 mock results Y: Final grade obtained However, I have the issue that sometimes, or most the times, the user may be using the app whilst not having taken ALL the mock exams yet, they may want to see if they are on track and use it once …

Given a hand drawn constellation (2d distribution of points) and a map of all stars, how would you find the actual star distribution most similar to the drawn distribution? If it's helpful, suppose we can define some maximum allowable threshold of distortion (e.g. a maximum Kolmogorov-Smirnov distance) and we want to find one or more distributions of stars that match the hand-drawn distribution. I keep getting hung up on the fact that the hand-drawn constellation has no notion of scale …

I picked about 20 5 gal buckets of grapes and will see little white spiders, earwigs, dust, crushed dry grape leaves, little stems, etc in with the clusters. Is it recommended to hose these down gently before putting them through the crusher? Is it important to let them dry off before putting them through the crusher? The hose water is potable.

Here I mentioned the url http://localhost/wp/2016/?category_name=cricket now i need to rearrange the url like http://localhost/wp/cricket/2016. here cricket is category name and 2016 is year. Remove the ?Query String Variable not a value of the querystring in the wordpress URl. I tried RewriteRule ^([0-9]{4})/?$/(.+)/([^/]+)/?$ /index.php/$1/?category_name=$2[QSA,L] But Not Working

Apologies for a very case specific question. I have a dataset of genes, with which I am using machine learning to predict if a gene causes a disease. One of the features I have is a beta value (which is the effect size of the gene's impact on the disease), and I'm not sure how best to interpret and use this feature. I condense the beta values from the variant level to the gene level, so a gene is left …

I have custom table like this: useraw 1. id (Primary*) 2. user_ip 3. post_id 4. time I am inserting data in the table using $wpdb->insert($table_name , array('user_ip' => $user_ip, 'post_id' => $postID, 'time' => $visittime),array('%s','%d', '%d') ); There are four rows I inserted using this code: id : 245 user_ip : 245.346.234.22 post_id : 24434 time : 255464 id : 345 user_ip : 245.346.234.22 post_id : 23456 time : 23467 id : 567 user_ip : 245.346.234.22 post_id : 57436 time …

I am working with a data set that, besides customer age and income, tells the balance a customer has in different type of bank accounts: Checking, Shares, Investment, Savings, Deposit, Mortgage, Loan, and Certificates. For accounts other than Checking, 0 represents that the account does not exist for the customers. There are 9800 customer observations with roughly 6000 checking accounts and 4000 savings accounts. For the others, the observations are less than 300. I have to use K-Means Clustering analysis …

I have created one main Page(Home Page) and many custom links in wp-admin. All custom links are linked to sections of Home Page. Example: Custom link About Us has a URL = #section1 and in my code I have linked it to: <div id="section1"> Text </div> In my CSS I have used .current-menu-item to highlight clicked link in menu: .site-header div.nav-wrap nav ul li.current-menu-item a:link, .site-header div.nav-wrap nav ul li.current-menu-item a:visited { color: #fff; text-shadow: -1px 1px 8px #ffc, 1px …

I'm trying to create a model which predicts Real estate prices with xgboost in machine learning, my question is : Can i combine two datasets to do it ? First dataset : 13 features Second dataset : 100 features Thé différence between the two datasets is that the first dataset is Real estate transaction from 2018 to 2021 with features like area , région And the second is also transaction but from 2011 to 2016 but with more features like …

I use the "classification_report" from from sklearn.metrics import classification_report in order to evaluate the imbalanced binary classification Classification Report : precision recall f1-score support 0 1.00 1.00 1.00 28432 1 0.02 0.02 0.02 49 accuracy 1.00 28481 macro avg 0.51 0.51 0.51 28481 weighted avg 1.00 1.00 1.00 28481 I do not understand clearly what is the meaning of macro avg and weighted average? and how we can clarify the best solution based on how close their amount to one! …

Using the Light GBM regressor, I have trained my data and, using Grid Search, I got the best parameters, but while testing with the best parameters I am getting different results each time, which means the model produces different results for each test iteration. I ran the lightgbm twice with the same parameters, but got different results in validation. I found the only random seed parameter to be baggingSeed. After fixing baggingSeed, the problem also occurred. Should I fix any …

I found this post about how to change a specific query but can't find a way to do the following: I have several queries on homepage retrieving posts from categories, posts from "New"s, posts from "Recipes", posts from "Promo" etc I have a slider area at the top that display posts from all categories that uses the tag "featured" How can I prevent all other queries on home from retrieving posts using "featured" tag so posts using the tag do …

I want to train a neural network and use open CV for facial recognition. Nicholas Martin, whose a user here on SE told me that this is a supervised learning class (clearly). So I need pictures and corresponding labels. So I thought hey! Maybe Facebook could be of help. So how can I label potentially millions of facebook pictures? Would it be by the user's profile name or is there a way to find out the name of the person …

I learned that tools like Pachyderm version-control data, but I cannot see any difference between that tool with Git. I learned from this post that: It holds all your data in a central accessible location It updates all depending data sets when data is added to or changed in a data set It can run any transformation, as long as it runs in a Docker, and accepts a file as input and outputs a file as result It versions all …

I have a strange problem I'm facing when using WP_Query with multisite in a plugin I'm writing which hooks into add_meta_boxes. I'm wanting to display all post titles in a dropdown in a meta box. While adding or editing a post in blog no. 2 (it could be any blog no.), I am looping through blog no. 1 and getting post titles from a custom post type to populate in a select dropdown. This works as it should, but in …

I have a dataset in which each sample contains a user id, a date, and the status associated with that particular user (active, expired & deactivated). The dataset contains records for a full year, but there are several days missing, and the goal of the project is to predict the status of a user on these missing days. Below is an example of one record: { "date": "20190101", "user": "301727881", "status": "active" }, Because the value of the variable I …

I am training a machine learning model (i.e., a classifier) on a large dataset. I know that I can get the same results using less data (about 30%) but I would like to avoid the trial and error process to find the 'right' amount of data to retain from the dataset. Of course I can create a script which automatically tried different thresholds but I was wondering if there is any principled way of doing this. It seems strange that …

I am working on a project where I have to update my model every time I get feedback x times. For example, showing an Advertisement on an App and then, when the person doesn't click on in it after seeing it multiple times in a day generates negative example. When they do that's positive. My initial dateset is not very big (<20,000) but it's going to significantly increase in future. I am starting with models like logistic Regression, SVM, XGBoost …

I have a WordPress multisite with one main site and four sub-sites. In a PHP template on my main site, I would like to get the posts from one of the sub-sites and print the permalinks to the page. How is this done? My code is below--when this code is executed, permalinks are indeed printed to the screen, but they are incorrect--the post name is correct, but the path is incorrect. $tp_blog_id = 4; switch_to_blog( $tp_blog_id ); $posts = get_posts( …

How can a few activation functions in neural networks handle so many different problems? I know some basics theory behind ANN, but I can't get what functions like the sigmoid function etc. have in common with for example image classification?

I am using vats-vs-dogs data set where the subdirectories are not precreated. Only 1 folder with 25000 images. (cat.001.jpg.... etc then dog.342.jpg.... etc) all in one folder. There are no separate folders called /cats or /dogs. How to use tf.keras.utils.image_dataset_from_directory function in such case ? Do I need to explicitly compartmentalize all dogs in /dog and all cats into /cats and then do it ? img_height = 300 img_width = 300 training_dir = 'drive/MyDrive/training1/dog-cat-train/train' train_ds = tf.keras.utils.image_dataset_from_directory( training_dir, labels='inferred', label_mode='categorical', …

I am working on Sentiment Analysis model. The dataset I have has three labels: positive, negative and neutral. But the problem is the data is not equal for labels. Say out of 100K : 75 K are neutral, 15K positive and 10K negative. I wanted to know whether it is necessary to choose equal distribution of labels while training or I can go ahead with unequal data and if so till what extent? Are there any ways to deal with …

I have been trying and searching to accomplish this. I have the "custom menu" widgets "Members Area", "Admin Area" in side bar, assigned menus to them. Fine, they display. I want to show "Admin Area" widget only when the current user is admin. I believe it has something to do with adding a filter to "sidebars_widgets". Honestly, i do not have a clue to target the "Admin Area" widget. How do I handle this ?

On a wordpress index page, I am only allowed to add 12 galleries. I would like to add many more. Is there a way that I can expand the gallery limit allowed on index pages? If this is not possible, is there a way that I can add multiple index pages to a folder page? Thank you for any help

I'm using this code to populate the dropdown menu in a meta box. $parents = get_posts( array( 'post_type' => 'jhk_story', 'orderby' => 'ID', 'order' => 'ASC', 'numberposts' => -1, 'exclude' => array(121, 131, 138), ) ); This post_type contains the parents of a post_type 'jhk_frames', which are the only child. So, the children contain in their post_parent field the post_ID of their parent. The parent contains in their post_parent field still the default zero. My question is: how do I …

I saw that everyone adds Dense( ) layer in their custom Bahdanau attention layer, which I think isn't needed. This is an image from a tutorial here. Here, we are just multiplying 2 vectors and then doing several operations on these vectors only. So what is the need of Dense( ) layer. Is the tutorial on 'how does attention work' wrong?

I am allowing Authors to delete their posts on the front end as they cant access the admin. I have this working, but what bothers me is the standard javascript onclick alert message - is there are way to style a js alert? From my understanding, no. Or to use jQuery for the message and use a modal window that I can style? Also, after deletion the user is returned to the same page which is good, but there is …

I`m training a siamese CNN to distinguish between pairs of images and though my train/val binary cross-entropy loss values show negative trend, implying some of the model parameters are being updated, I noticed that convolution kernels barely change while their biases change significantly tensorboard weights histogram image. Also, while loss value decreases, accuracy appears to be frozen for some epochs and then instantly shoots up accuracy and loss plots. Q1: If this is caused by vanishing gradient, why would it …

I am analysing a bunch of data files which represent responsiveness of cells to addition of a drug. If a drug is not added, cell responds normally, if it is added, it shows abnormal patterns: , . We decided to analyse this using an amplitude histogram, in order to distinguish between a change in amplitude and in change of a probability of elliciting the binary response. What we get with file 1 is : So we fit a pdf on …
