I am really stumped at the moment about how to solve a particular problem. I have many time series like this: This represents the number of hours a person spends on a website each day throughout the year. Any days where they are not seen to be using the website have zero values, rather than missing values. What I really want to do is to calculate a metric telling me to what extent there is a consistent "1 hour per …

I'm trying to determine whether it's best to use linear or quadratic discriminant analysis for an analysis that I'm working on. It's my understanding that one of the motivations for using QDA over LDA is that it deals better with circumstances in which the variance of the predictors is not constant across the classes being predicted. This is true for my data, however I intend to carry out principal components analysis beforehand. Because this PCA will involve scaling/normalising the variables, …

Given the relatively simple form of the model of standard logistic regression. I was wondering if there is an exact calculation of shap values for logistic regressions. To be clear I am looking for a closed formula depending on features ($X_i$) and coefficients ($\beta_i$) to calculate Shapley values and their corresponding importance.

How does feature selection impact outlier detection and also, removing outliers impact feature selection? It could be a basic question. However, just to know the boundaries, I asked. Thanks in advance. I have gone through the following:Feature selection and outlier order

I am trying to build a machine learning model in python. I used pytorch and sklearn to make the model. My model is a bit complicated: I have between one to 8 input feature but several target variables. My target variables are kind of time series. Shape of my taget variable is 50x169 but my input feature the shape is between 50x1 to 50x8. I showed three different series in the upladed figure. I used algorithms like DecisionTreeRegressor and RandomeForestRegressor …

I'm filtering my custom post type based on author. I want all users to be able to: 1 - in the list everyone can see the posts created by the admin. 2 - users can also see their own posts in the list, but not those of other users. I can list by admin id only or current user id only, but not both. Code: function list_cpt_by_author_id(){ $user = new WP_User(get_current_user_id()); $authors_id = array( array('author' => "1"), array('author' => "$user"), …

I am dealing with time series data with +200K (every minute for 6 months)record of gas turbine I am trying to early detect the fault (0 or 1-fault). The issues with the data are: 1.the fault occurred only 5 times (by observing the sudden shutdown). make the data hugely imbalanced. 2.(unsupervised) No binary output. I used 2 of the variables as my output and used them for binary clustering (kmeans) but the result not very good as there are false …

I am very new to wordpress/php, I don't fully understand it yet. So I've implemented firebase cloud messaging in a wordpress app and I am able to send push notifications with "FCM Push Notification from WP" plugin, and it also works with scheduled posts IF the admin panel is open when the scheduled post is due. Otherwise it will send the notification when I browse to the admin panel. I really don't understand this code fully, but what could I …

I'm currently getting the data from a custom taxonomy using this: $terms = get_terms(array( 'taxonomy' => 'my_custom_taxonomy_name', 'hide_empty' => true )); Now, this returns a lot of stuff in each WP_Term object; term_id, name, slug, term_group, term_taxonomy_id, taxonomy, description, parent, count and filter. I only need to get 2 of those: name and slug. How can I filter that query so it doesn't returns all that unused data?

I am a newbie to machine learning and I am trying to apply the SVD on the movielens dataset for movie recommendation. I have a movie-user matrix where the row is the user id, the column is the movie id and the value is the rating. Now, I would like to perform normalization on the movie-user matrix (subtract the data by users ratings mean). Then pass the normalized matrix to Scipy.sparse svds as follow: from scipy.sparse.linalg import svds U, sigma, …

I need to add product categories to Wordpress menu, but when I'm doing this with WP interface it lose the hierarchy I tried with WP-CLI, but there is no method to specify wich item is the child. There is a method to do it? There is a ton of categories (3-4 level deep), I cannot do this manually I can buy also a plugin. Can you suggest something? Thanks a lot

The representation learning model produces vectors for objects. I want the cosine similarity of some vector pairs to be (close to) 1, some to be 0. What objective function should I use? MSE as training a regression model?

I've been modifying the built in WP search using the pre_get_posts filter, allowing the user to sort the posts (including a bunch of custom post types) by different fields. The problem I'm having though is that when I tell WP to sort by a meta value it will exclude all posts that don't have that meta value set. This causes the number of results to change if you change sorting from say "Price" to "Date" because "Posts" don't have "Price" …

I have Used the function dynamic_sidebar('sidebarId') in the sidebar.php file. and all the functionality of the sidebar is Working succsessfully My Question is How To Change the Html of the sidebar widgets and add some classes in widget items To fit My Design ? Thank You in advance

Here is my understanding of the relation between MLE & Gradient Descent in Logistic Regression. Please correct me if I'm wrong: 1) MLE estimates optimal parameters by taking the partial derivative of the log-likelihood function wrt. each parameter & equating it to 0. Gradient Descent just like MLE gives us the optimal parameters by taking the partial derivative of the loss function wrt. each parameter. GD also uses hyperparameters like learning rate & step size in the process of obtaining …

I am trying to understand RNN. I got a good sense of how it works on theory. But then on PyTorch you have two extra dimensions to your input data: batch size (number of batches) and sequence length. The model I am working on is a simple one to one model: it takes in a letter than estimates the following letter. The model is provided here. First please correct me if I am wrong about the following: Batch size is …

I am very new to wordpress. I installed it on my linux server lately and uploaded a them on it.

The course of David Silver about Reinforcement Learning explains how you get the optimal policy from the optimal value function. It seems to be very simple, you just have to act greedily, by maximizing at each step the value function. In the case of a small grid world, once you have applied the Policy Evaluation algorithm, you get for example the following matrix for the value function : You start from the up-left corner and the unique actions are the …

I'm building a Wordpress site in which an admin can upload a video file from post metabox. After that post is saved and the video file is attached to the post, I used ffmpeg to get the screenshot at the first second of video, then save this screenshot as a JPG file in 'tmp' directory in theme directory. Finally, I want to programmatically make this screenshot as post featured image. I use media_sideload_image function, which generally be used to get …

I have a custom function that pulls in (3) posts from another Wordpress blog, and it's pulling them from specific categories I specify via a shortcode. Now, with that said, I cannot get it to function and display the actual image, as I can only get it to show the featured Image's (media attachment's) ID itself. Here is my functional code, which works except the image is not displayed, instead it's the images ID (numerical value) function feedpuller_func($atts) { $url …

The following is a small snippet of the code, but I'm trying to understand the results of model.fit with train and test dataset vs the model.evaluate results.

I'm trying to understand the difference between random forests and extremely randomized trees (https://orbi.uliege.be/bitstream/2268/9357/1/geurts-mlj-advance.pdf) I understand that extratrees uses random splits and no bootstrapping, as covered here: https://stackoverflow.com/questions/22409855/randomforestclassifier-vs-extratreesclassifier-in-scikit-learn The question I'm struggling with is, if all the splits are randomized, how does a extremely randomized decision tree learn anything about the objective function? Where is the 'optimization' step?

Is there a way to find relatedness between data and the data obtained after some transformation applied to it? i.e. given a data I need to find the most related data(most of the values in that data can be obtained) that can be found by applying some transformation in original data. I tried but couldn't find a proper answer, most of the discussion that I found is about linear transformation or log transformation but I want to find a way …

For a Neural Machine Translation (NMT) task, my input data has relational information. This relation could be modelled using a graphical structure. So one approach could be to use Graph Neural Network (GNN) and use a Graph2Seq model. But I can't find a good generational model for GNN. Instead, I want to use Transformer. But then the challenge is how can I embed structural information there? Is there any open source artefact for Relational Transformer that I can use out …

The gradient descent: $\theta_{t+1}=\theta_t-a\frac{\partial}{\partial \theta_j}J(\theta)$ But specifically about $J$ cost function (Mean Squared Error) partial derivative: Consider that: $h_\theta(x)=\theta_0+\theta_1x$ $\frac{\partial}{\partial\theta_j}J(\theta) = \frac{\partial}{\partial\theta_j}\frac{1}{2}(h_{\theta}(x)-y)^2$ $\ \ \ \ \ \ \ \ \ \ \ \ =2\frac{1}{2}(h_{\theta}(x)-y)*\frac{\partial}{\partial\theta_j}(h_{\theta}(x)-y)$ $\ \ \ \ \ \ \ \ \ \ \ \ = (h_{\theta}(x)-y)*\frac{\partial}{\partial\theta_j}(\sum_{i=0}^{n}\theta_ix_i-y_i)$ $\ \ \ \ \ \ \ \ \ \ \ \ = (h_{\theta}(x)-y)x_j$ It´s not clear to me how $x_j$ is calculated: $\frac{\partial}{\partial\theta_j}(\sum_{i=0}^{n}\theta_ix_i-y) = x_j $ Can anyone help me …

Typically the input to neural network (NN) is transformed to have zero mean and 1 std. I wonder why std scale should be 1? What about other scales? 10? 100? Doesn't it make sense to provide NN with input of wider range so that NN can separate different clusters easier and deal with loss function for each cluster in more simple and robust way? Did someone here tried different scales and can share his experience? If answer depends on the …
