The system learned and saved the values entered on the Validation screen based on the anchors after the user-specified the corresponding regex, dictionary, or composite type in the Suggestion Box pop-up window.<\/p>\n<p>In Ephesoft Transact v.2019.1, the approach to machine learning has been majorly revised. The new core machine learning is designed using the latest technology and helps to achieve better extraction accuracy as well as shorter \u201ctime to value\u201d. Based on a much more focused approach, the new mechanism has been created only for Invoice batch classes. The entire process is greatly simplified and improved \u2013 the system now automatically identifies the document type, and then searches and finds configured key-value pairs as explained in detail below.<\/p>\n<p>Apart from the core machine learning, there is also enhanced machine learning (EML), which can be used for any batch class. This mechanism allows the user to learn the data entered on the Validation screen. The operator only needs to populate the index fields and Transact will automatically create and save extraction rules and ML value types.<\/p>\n<p><strong>Core machine learning<\/strong> is designed only for Invoice batch classes as mentioned above. It includes several pre-configured ML fields, which can be mapped against the index fields created by the operator. Once the mapping is done, the system automatically extracts the values based on the in-built learning.<\/p>\n<p>To implement this functionality:<\/p>\n<ul>\n<li>The <strong>Invoice<\/strong> category has been added under the Category column on the Batch Class Management screen.<\/li>\n<li>The <strong>ML Field Mapping<\/strong> column has been added to the Index Fields screen (Batch Class -&gt; Document Types -&gt; Index Fields).<\/li>\n<li>The new <strong>dictionaries<\/strong> folder has been created under the SharedFolders at the application level. It contains files with synonyms (<strong>mllocale<\/strong> folder) and regular expressions (<strong>mlregexes<\/strong> folder) created for each pre-configured ML index field type for each supported language.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"wp-image-30474\" src=\"https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-12.png\" width=\"793\" height=\"394\" srcset=\"https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-12.png 1041w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-12-300x149.png 300w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-12-768x381.png 768w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-12-1024x509.png 1024w\" sizes=\"(max-width: 793px) 100vw, 793px\" \/><\/p>\n<p>The core machine learning mechanism can automatically detect the language of the HOCR file. The following languages are currently supported under the core machine learning for invoices (one or more languages can be present on a single invoice):<\/p>\n<ul>\n<li>English<\/li>\n<li>French<\/li>\n<li>German<\/li>\n<\/ul>\n<p><strong>Enhanced machine learning<\/strong> can be used for any batch class and is designed to learn values provided by the operator on the Validation screen. The learned data is saved in a JSON file in the enhanced-machine-learning folder (SharedFolders\\&lt;Batch Class ID&gt;\\enhanced-machine-learning\\&lt;Document Type&gt;) to be used for further batches.<\/p>\n<p>To implement this functionality:<\/p>\n<p><span style=\"font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen-Sans, Ubuntu, Cantarell, 'Helvetica Neue', sans-serif\">&#8211; The ENHANCED_MACHINE_LEARNING_EXTRACTION plugin has been created under the Extraction module with ON\/OFF switch.<\/span><\/p>\n<p>In the current implementation, the core machine learning functionality is provided only for the Invoice category and only for index fields. More documentation categories, as well as support for Invoice table machine learning, will be added in future releases.<\/p>\n<p><strong>Important<\/strong>: The machine learning approach used earlier for index field extraction has been discontinued. If you are importing batch classes with machine learning data from previous versions of Transact into Transact v.2019.1, the learned data will be redundant due to the changed ML mechanism.<\/p>\n<p>Machine learning for tables did not undergo any changes and will work as before. The data imported along with batch classes from previous Ephesoft Transact versions will be saved and used as intended. Machine learned table data does not require re-learning after the import.<\/p>\n<h2><a id=\"post-30461-_Toc534987649\"><\/a><strong>Core Machine Learning for Invoices<\/strong><\/h2>\n<p><strong>Prerequisites<\/strong><\/p>\n<p>&#8211; The\u00a0MACHINE_LEARNING_BASED_EXTRACTION plugin\u00a0should be added to the Extraction Module.<\/p>\n<p><img decoding=\"async\" class=\"wp-image-30476\" src=\"https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-14.png\" width=\"900\" height=\"430\" srcset=\"https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-14.png 1120w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-14-300x143.png 300w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-14-768x367.png 768w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-14-1024x489.png 1024w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>&#8211; On the Machine Learning-Based Extraction Plugin screen, the Machine Learning-Based Extraction Switch should be turned ON.<\/p>\n<p><img decoding=\"async\" class=\"wp-image-30478\" src=\"https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-16.png\" width=\"875\" height=\"405\" srcset=\"https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-16.png 1154w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-16-300x139.png 300w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-16-768x355.png 768w, https:\/\/ephesoft.com\/docs\/wp-content\/uploads\/2019\/02\/word-image-16-1024x474.png 1024w\" sizes=\"(max-width: 875px) 100vw, 875px\" \/><\/p>\n<p>&#8211; Optionally, the ENHANCED_MACHINE_LEARNING_EXTRACTION plugin can be added to the Extraction module if you want to be able to learn values on the Validation screen.
