Updated packages. Improve hierarchy vis. Better models - mixedbread and phi3. Now option to split texts into sentences before modelling.

Minor cleaning, csv formatting changes

Reduce outliers now more efficient and relabels with correct vectoriser. Default topic labels now tidier. Hiearchical topics outputs more useful for joining to df afterwards. Switched low resource reduction algorithm to UMAP as default is not good.

Should now parse custom regex correctly. Will now wipe previously created embeddings if 'low resource mode' option switched.

Allowed for uploading custom regex for cleaning. Fixed calculate all probabilities, reduce outliers. Added text tree for hierarchical modelling.

Upgraded to Gradio 4.16.0. Guide for converting to exe added.

Hopefully now LLM download from hub should work

Note about LLM not working now successfully added!

Added note to say that LLM representation is not currently working on the HF website

Trying to download LLM to local_dir instead of cache_dir

LLM model save is failing in Huggingface - attempting instead to save to base folder

Some text changes. Fixed a couple of TF-IDF embeddings issues

Switched embeddings to low resource TF-IDF by default. Some text changes.

Fixed file load with files including capital letters

Added clean data options, improved re-representation options and visualisation. General format changes

Allowed for loading in external topic labels. A few visualisation modifications.

Model save now checks and makes a folder before writing the model

Lots of general fixes. New visualisations, fixed hierarchical vis for zero shot. Added calc all probabilities.

Changed Phi model to smaller StableLM 2 1.6. Fixed a None type detection error.

Disabled console logging as it was getting in the way of file load into the app

Switched embeddings model to BGE Small 1.5 as Jina seemed unable to do zero shot topic modelling properly

Added minimum similarity slider for zero shot topic modelling

model and hierarchy details should now save properly

Split off LLM representation, visualisation, and reduce outliers from main function. Added hierarchical visualisation and logs

More efficient embeddings save and representations load/process. Custom visualisation hover option added, formatting improvements. Version 0.1?

App should now check if embeddings are loaded before topic modelling. And will save only once.

Hopefully fixed install and load of LLM model on systems without a HF_HOME environmental variable

Added option to reduce outliers based on closest topic

Returned TruncatedSVD components to 100 - higher values don't seem to help

Greatly increased low resource process dimensions for higher quality. Visualisations disabled by default to increase speed.

Greatly improved low resource mode speed (at cost of potential quality)

Changed zero shot min similarity to 0.5

Added controls for saving topic models and visualisation. Removed custom UMAP layer

Now should save embeddings by default. Added random seed to representation

Fixed llm_config, environmental variable, zero shot topic model errors with quick embeddings

removed cpu_config as causing problems

Model export changed to safetensors. Improved representational model function. Got zero shot topic modelling working

Removed reference to environmental variable

Changed readme colour to yellow
