title: Replication Data for: Spatially resolved ionization current measurements using an active-matrix transimpedance amplifier array

description: This dataset holds all measurement data, as well as the evaluation and plotting scripts to replicate all figures of the paper.

The data is structered in folders of the figures. In the most cases a folder inlcudes the figure (.pdf), a subfolder named Plot and a subfolder named Raw data and evaluation script. The Plot folder contains the plotting script (.py) and the plotted data (.txt). The Raw data and evaluation script folder contains the recorded (unprocessed) data (.csv, .xlxs) and a python script (.py), which generates the plotted data from the raw data.

title: Preprocessed Conversational Mental Health Dataset for AI Model Training

description: Title: Preprocessed Dataset for Conversational AI and Mental Disorder Classification Using GPT-3.5 and DistilRoBERTa

Description: This dataset supports the research paper titled "Conversational AI for Mental Health Diagnostics using GPT-3.5 and Distil-RoBERTa". It contains a cleaned, filtered, and semantically selected dataset constructed by combining two publicly available sources:

1.      Mental Health Conversational Data (Elvis, 2022):

·         Kaggle Link

·         Used for training the GPT-3.5-based conversational model with mental health-related dialogues, FAQs, and therapeutic scenarios.

2.      Mental Disorders Identification (Reddit) (Adha, 2022):

·         Kaggle Link

·         Contains ~700,000 Reddit posts labeled for mental disorders. Used to train a distilroberta-base classifier for four classes: Anxiety, Depression, Borderline Personality Disorder (BPD), and Bipolar Disorder.

To ensure high-quality, semantically rich examples, we applied the following:

·         Text cleaning and filtering to remove noise, low-context replies, and troll content.

·         Semantic sample selection using Sentence-BERT
(all-MiniLM-L6-v2) for embedding generation.

·         t-SNE-based dimensionality reduction followed by Euclidean distance-based selection of top 1000 representative samples per class.

This Zenodo entry includes only the final processed dataset (CSV format), label descriptions, and supporting metadata.

All source code and training pipelines are openly available on GitHub:https://github.com/diwakardkk/Conversational-AI
