What are some approaches to handle uncertainty in transition and observation probability in POMDP?

What are some common approaches to estimate a (transition or observation) probability, when the probabilities are not exactly known? When realizing a POMDP model, the state model needs additional information in terms of transition and observation probability. Often these probabilities are not known and an equal distribution is also not given. How can we proceed?

Can dropout layers not influence LSTM training at all

I am working on a project that requires time-series prediction (regression) and I use LSTM network with first 1D conv layer in Keras/TF-gpu as follows: model = Sequential() model.add(Conv1D(filters=60, activation=’relu’, input_shape=(x_train.shape[1], len(features_used)), kernel_size=5, padding=’causal’, strides=1)) model.add(CuDNNLSTM(units=128, return_sequences=True)) model.add(CuDNNLSTM(units=128)) model.add(Dense(units=1)) As an effect my model is clearly overfitting: So I decided to add dropout layers, first…

How to Make post like system & get avater, user name, link of who liked the post

I have already a like system function, JS & like button. The code is //function <?php function post_like_table_create() { global $wpdb; $table_name = $wpdb->prefix. “post_like_table”; global $charset_collate; $charset_collate = $wpdb->get_charset_collate(); global $db_version; if( $wpdb->get_var(“SHOW TABLES LIKE ‘” . $table_name . “‘”) != $table_name) { $create_sql = “CREATE TABLE ” . $table_name . ” ( id…

How Can I Write to Console During Shutdown?

I am trying to prevent the user from shutting down or rebooting without physically removing a flash card from the machine. To do that, I have written a SystemD service, removeflash.service: [Unit] Description=Prompt user to remove flash card [Service] ExecStop=/usr/lib/systemd/flashshutdown.sh Type=oneshot RemainAfterExit=yes [Install] WantedBy=multi-user.target Requires=rsyslog.service The flashshutdown.sh is a bash script, as follows: #! /bin/bash…
