I am trying to apply the following model on my data which is consists of (4030 samples as 5 classes) each sample is MFCC features which is extracted from an audio clip consisting of (20 second) and I am trying to apply classification, but I got very poor accuracy and I also have overfitting, , Although I am using data augmentation and I also try to apply Batch Normalization to improve overfitting but the result is very bad. the Model: …

I have a membership site with 4000+ users currently on it. I am needing to give both new/existing users an automatic ID number. its very similar to this: Create Unique ID for user However, this only works for new users, I need it to work for the current users too. So for instance, user id 3421 would get membership number 3421. This is what I have so far: (pretty much all from above link) function fb_add_custom_user_profile_fields( $user ) { ?> …

I have set up SMTL like this, add_action( "phpmailer_init", "send_smtp_email" ); function send_smtp_email( $phpmailer ) { ini_set("sendmail_from","[email protected]"); ini_set("sendmail_path","[email protected]"); // Define that we are sending with SMTP $phpmailer->isSMTP(); // The hostname of the mail server $phpmailer->Host = "localhost"; // Use SMTP authentication (true|false) $phpmailer->SMTPAuth = false; // SMTP port number - likely to be 25, 465 or 587 $phpmailer->Port = "25"; // Encryption system to use - ssl or tls $phpmailer->SMTPSecure = "tls"; $phpmailer->From = "[email protected]"; $phpmailer->FromName = "XYZ"; } and …

I want to train my application for phrase similarity. I want my model to predict similarity score for phrases as shown in below examples. ex- International Business Machines = I.B.M Synergy Telecom = SynTel Beam inc = Beam Incorporate Sir J J Smith = Johnson Smith Alex, Julia = J Alex James B. D. Joshi = James Joshi James Beaty, Jr. = Beaty Is there any dataset available to train this type of model?

I have a time series of the following format: time product1 product2 product3 product4 t1 40 50 68 47 t2 55 60 70 100 t3 606 20 500 52 ... Values are sales. On day t1, how much money was spent on customers buying product1 for example. I want to do time series clustering on this dataset. I am trying to use matrix profile distance. However, this method assumes only 1 dimensional data. Is there anyways to work around this?

so... this is a brand new chapter for me, i've googled for a solution and found loads but nothing working for me unfortunately. function column_title($item){ $actions = array( 'edit' => sprintf('<a href="?page=%s&action=%s&ID=%s">Edit</a>',$_REQUEST['page'],'edit',$item['ID']), 'delete' => sprintf('<a href="?page=%s&action=%s&ID=%s">Delete</a>',$_REQUEST['page'],'delete',$item['ID']), ); return sprintf('%1$s %2$s', $item['ID'], $this->row_actions($actions) ); } above i've added a delete and edit action, and i think i've used the sprintf the proper way but i'm not sure, database table contains the following columns ID, usr_id, date, begin, end, pause, egenb, tot, …

I am wondering why validation loss of this regression problem is not decreasing while I have implemented several methods such as making the model simpler, adding early stopping, various learning rates, and also regularizers, but none of them have worked properly. any suggestions would be appreciated. here is my code and my outputs: optimizer = keras.optimizers.Adam(lr=1e-3) model = Sequential() model.add(LSTM(units=50, activation='relu', activity_regularizer=tf.keras.regularizers.l2(1e-2), return_sequences=True, input_shape=(x_train.shape[1], x_train.shape[2]))) model.add(Dropout(0.2)) model.add(LSTM(units=50, activation='relu', activity_regularizer=tf.keras.regularizers.l2(1e-2), return_sequences=False)) model.add(Dropout(0.2)) model.add(Dense(y_train.shape[1])) model.compile(optimizer=optimizer, loss='mae') callback = tf.keras.callbacks.EarlyStopping(monitor='loss', patience=3) history = …

I'm retroactively creating a post with wp_insert_post() and attaching a featuring image to it. I need the image to go into the folder that corresponds to the post's publishing date. I'm using time parameter in wp_handle_upload function that supposed to move files to the directories according to the parameter value (see in the code - $upload_date - static value for now). But right now the image moves to the current year/month folder ignoring $upload_date (Ex.: Supposed to go 2007/11, goes …

Is the Cross Entropy Loss (CEL) important at all, because at Backpropagation (BP) only the Softmax (SM) probability and the one hot vector are relevant? When applying BP, the derivative of CEL is the difference between the output probability (SM) and the one hot encoded vector. For me the CEL output, which is very sophisticated, does not play any roll for learning. I´m expecting a fallacy in my reasoning, so could somebody please help me out?

I want to use another link for logout because I have /wp-admin/* protected with htpassword. Is there a way to do this? Something like creating a custom page like site.com/logout then use it as my new logout link? Thanks!

I am writing a plugin which creates a custom post type and two associated custom taxonomies. The custom post type list/archive page should be filterable by terms in one or both taxonomies i.e not just a filter by one taxonomy term. The filters should be displayed as two separate tag clouds. Does anyone have experience of implementing this functionality and can recommend any suitable plugins?

In Rapidminer, are the decision tree's weights a measure of the "importance" of attributes in the splitting procedure ? If yes, why is useful to know these weights ? Are there better methods to know the most discriminant features in a data set ?

I bought a Theme which unfortunately has some static content, I managed to hide and remove some via editing and the custom css. But I have a text field above the navigation where it says "Work Time" I need a way to write the German and English version of that text somewhere in my WP-Admin panel and tell the theme to load selected language text into that text field. I have coded some stuff in php js and mysql so …

I have created and analyzed around 16 machine learning models using WEKA. Right now, I have a CSV file which shows the models' metrics (such as percent_correct, F-measure, recall, precision, etc.). I am trying to conduct a (modified) student's t-test on these models. I am able to conduct one (according to THIS link) where I compare only ONE variable common to only TWO models. I want to perform a (or multiple) t-tests with MULTIPLE variables and MULTIPLE models at once. …

I was asked to fix a wordpress based site and I don't get what's going on with it. The (custom) theme has a page-home.php that is the Home page. Whatever edits I make to this file, if I refresh the page logged in wp-admin (so, I'm an admin), the change is seen, but logged out (anonymous - as the site is intended to be used) it's still the old content. I did the following: downloaded all site locally, opened all …

There's this dataset containing the metadata of Twitch's top 1,000 streamers of 2020. You can have the details here. I am currently participating in a challenge to predict the values for Followers gained, by creating and training the model using the remaining features from the dataset. The kernel objective is to get the lowest RMSE (Root-Mean Squared Error) metric value from the model's predictions. Until now, I have made numerous attempts to lower down the RMSE loss value as much …

Can I understand in this way? Let me know if any statement is wrong or not accurate. Reason of data filling: Assume I have a consecutive data (e.g., daily log data), and partial data are missing. In order to make some calculation (e.g., mean value), we first need to assign values to the missing parts (e.g., equal to existing data) Forward filling and backward filling are two data filling methods. The difference is the filling direction? E.g., Tuesday data (missing) …

I am working on a website on WordPress and I have it set to where the bottom of the post will automatically link to a random previous post with a picture from that previous link but a notice keeps popping up on the bottom. It says there is something wrong with the previous post image url but the website sets this automatically and it works for all my other posts. Since it is undefined should I try to define it …

Why in Orange versions after 3.18 is not possible to visualize categorical data in Scatter Plot widget?

I'm trying to filter so that only the creators of the respective categories can edit them. I created a cat_author meta field and associated it to the taxonomy. In this way, every taxonomy has an author. And I tended to filter with add_filter( 'pre_get_terms', 'filter_cat_by_u_id', 99, 1 ); function filter_cat_by_u_id( $query ) { if ( ! is_admin() ) { return $query; } global $pagenow; if ( 'edit-tags.php' === $pagenow ) { $meta_query = array( array( 'key' => 'cat_author', 'value' => …

I am encountering a strange problem which I couldn't solve so far. I'm calling a .php script via cronjob (Debian/GNU Linux). To use wordpress functionailty I added: define('WP_USE_THEMES', false); require( '/full/path/to/wp-blog-header.php' ); Now database queries and default wordpress functionality all works fine, but I also call some functions provided by a plugin (namely advanced custom fields, the problem however affects other plugins as well as I tested) the following php error is returned: PHP Fatal error: Call to undefined function …

I had a setup a yolo4 pytorch framework in google colab by cloning git clone https://github.com/roboflow-ai/pytorch-YOLOv4.git. I generated checkpoints by giving training. As we need more robust training model, I given training again with assigning pretrained checkpoints but it seems loss started with high value as like first time training. Code is for training !python train.py -b 2 -s 1 -l 0.001 -g 0 -pretrained ./Yolov4_epoch100_latest.pth -classes 1 -dir ./train -epochs 100. Not sure if my pretrained checkpoint is used …

Disclaimer: I'm relatively new to the data science and ML world -- still trying to get a firm grasp on the fundamentals. I'm trying to overcome a regression challenge involving a large, multi-dimensional dataset, but am hitting a roadblock when it comes to my input data. This dataset consists of a few key input criteria: [FLOW, TEMP, PRESSURE, VOLTAGE_A] and a single output variable, VOLTAGE_B (this is what I'm hoping to effectively model and predict). I'm able to handle this …

I have multiple columns for loan installment repayment. As there is a field for month of repayment, I want to predict if the customer is going to pay next month's installment or not. As I have multiple variables and target variable as installment paid (Y/N), despite repayment being dependent on time variable, i.e., installments paid in past months, I'm looking to solve this problem with time series classification. Any references will be appreciated.

I need a fix for this web page. The page is attached if you wish to review the code. The pagination on each tab does not reset to 1 when the user has made a selection.
