Pathology is the gold standard of clinical diagnosis. Artificial intelligence (AI) in pathology becomes a new trend, but it is still not widely used due to the lack of necessary explanations for pathologists to understand the rationale. Clinic-compliant explanations besides the diagnostic decision of pathological images are essential for AI model training to provide diagnostic suggestions assisting pathologists practice. In this study, we propose a new annotation form, PathNarratives, that includes a hierarchical decision-to-reason data structure, a narrative annotation process, and a multimodal interactive annotation tool. Following PathNarratives, we recruited 8 pathologist annotators to build a colorectal pathological dataset, CR-PathNarratives, containing 174 whole-slide images (WSIs). We further experiment on the dataset with classification and captioning tasks to explore the clinical scenarios of human-AI-collaborative pathological diagnosis. The classification tasks show that fine-grain prediction enhances the overall classification accuracy from 79.56 to 85.26%. In Human-AI collaboration experience, the trust and confidence scores from 8 pathologists raised from 3.88 to 4.63 with providing more details. Results show that the classification and captioning tasks achieve better results with reason labels, provide explainable clues for doctors to understand and make the final decision and thus can support a better experience of human-AI collaboration in pathological diagnosis. In the future, we plan to optimize the tools for the annotation process, and expand the datasets with more WSIs and covering more pathological domains.

This dataset is constructed based on the MORE dataset and is applicable to MLLM SFT.

About the MORE dataset

arXiv: https://arxiv.org/abs/2312.09753

To construct the MORE dataset, we choose to use multimodal news data as a source rather than annotating existing MRE datasets primarily sourced from social media. Multimodal news data has selective and well-edited images and textual titles, resulting in relatively good data quality, and often contains timely and informative knowledge. We obtained the data from The New York Times English news and Yahoo News from 2019 to 2022, resulting in a candidate set of 15,000 multimodal news data instances covering various topics. We filtered out unqualified data and obtained a meticulously selected dataset for our research purposes. Then the candidate multimodal news was annotated in the following three distinct stages.

Stage 1: Entity Identification and Object Detection. We utilized the AllenNLP named entity recognition tool1 and the Yolo V5 object detection tool2 to identify the entities in textual news titles and the object areas in the corresponding news images. All extracted objects and entities were reviewed and corrected manually by our annotators.

Stage 2: Object-Entity Relation Annotation. We recruited well-educated annotators to examine the textual titles and images and deduce the relations between the entities and objects. Relations were randomly assigned to annotators from the candidate set to ensure an unbiased annotation process. The data did not clearly indicate any pre-defined relations will be labeled as none. At least two annotators are required to independently review and annotate each data. In cases where there were discrepancies or conflicts in the annotations, a third annotator was consulted, and their decision was considered final. The weighted Cohen's Kappa is used to measure the consistency between different annotators.

Stage 3: Object-Overlapped Data Filtering. To refine the scope of multimodal object-entity relation extraction task, we only focused on relations in which visual objects did not co-occur with any entities mentioned in the textual news titles. This process filtered down the data from 15,000 to over 3,000 articles containing more than 20,000 object-entity relational facts. This approach ensured a dataset of only relatable object-entity relationships illustrated in images, rather than those that were already mentioned explicitly in the textual news titles, resulting in a more focused dataset for the task.

Single-cell RNA sequencing (scRNA-seq) is an invaluable tool for profiling cells in complex tissues and dissecting activation states that lack well-defined surface protein expression. For immune cells, the transcriptomic profile captured by scRNA- seq cannot always identify cell states and subsets defined by conventional flow cytometry. Emerging technologies have enabled multimodal sequencing of single cells, such as paired sequencing of the transcriptome and surface proteome by CITE-seq, but integrating these high dimensional modalities for accurate cell type annotation remains a challenge in the field. Here, we describe a machine learning tool called MultiModal Classifier Hierarchy (MMoCHi) for the cell-type annotation of CITE-seq data. Our classifier involves several steps: 1) we use landmark registration to remove batch-related staining artifacts in CITE-Seq protein expression, 2) the user defines a hierarchy of classifications based on cell type similarity and ontology and provides markers (protein or gene expression) for the identification of ground truth populations within the dataset by threshold gating, 3) progressing through this user-defined hierarchy, we train a random forest classifier using all available modalities (surface proteome and transcriptome data), and 4) we use these forests to predict cell types across the entire dataset. Applying MMoCHi to CITE-seq data of immune cells isolated from eight distinct tissue sites of two human organ donors yields high-purity cell type annotations encompassing the broad array of immune cell states in the dataset. This includes T and B cell memory subsets, macrophages and monocytes, and natural killer cells, as well as rare populations of plasmacytoid dendritic cells, innate T cells, and innate lymphoid cell subsets. We validate the use of feature importances extracted from the classifier hierarchy to select robust genes for improved identification of T cell memory subsets by scRNA-seq. Together, MMoCHi provides a comprehensive system of tools for the batch-correction and cell- type annotation of CITE-seq data. Moreover, this tool provides flexibility in classification hierarchy design allowing for cell type annotations to reflect a researcher’s specific experimental design. This flexibility also renders MMoCHi readily extendable beyond immune cell annotation, and potentially adaptable to other sequencing modalities. We performed CITE-seq on immune cell populations from human blood and different human organ donor tissues.

Should be open like: x = Biosignal.load(path) LTBio Package: https://pypi.org/project/LongTermBiosignals/ Under the directory biosignal, the following tree structure is found: subject/x.biosignal, where subject is the subject's code, and x is any of the following { acc_chest, acc_wrist, ecg, eda, emg, ppg, temp }. Each file includes the signals recorded from every sensor that acquires the modality after which the file is named, independently of the device. Channels, activities and time intervals can be easily indexed with the index operator . A sneak peak of the signals can also be quickly plotted with: x.preview.plot() Any Biosignal can be easily converted to NumPy arrays or DataFrames, if needed. b) CSV files. Can be open like: x = pandas.read_csv(path) Pandas Package: https://pypi.org/project/pandas/ These files can be found under the directory csv, named as subject.csv, where subject is the subject's code. There is only one file per subject, containing their full session and all biosignal modalities. When read as tables, the time axis is in the first column, each sensor is in one of the middle columns, and the activity labels are in the last column. In each row are the samples of each sensor, if any, at each timestamp. At any given timestamp, if there is no sample for a sensor, it means the acquisition was interrupted for that sensor, which happens between activities, and sometimes for short periods during the running activity. Also in each row, on the last column, is one or more activity labels, if an activity was taking place at that timestamp. If there are multiple annotations, the labels are separated by vertical bars (e.g 'run | sprint'). If there are no annotations, the column is empty for that timestamp.

In order to provide a tabular format with sensors with different sampling frequencies, the sensors with sampling frequency lower than 500 Hz were upsampled to 500 Hz. This way, the tables are regularly sampled, i.e., there is a row every 2 ms. If a sensor was not acquiring at a given timestamp, the corresponding cell with be empty. So, not only the segments with samples are regularly sampled, but the interruptions are also discretised. This means that if, after an interruption, a sensor starts acquiring at a non regular timestamp, the first sample will be written on the previous or the following timestamp, by half-up rounding. Naturally, this process cumulatively introduces lags in the table, some of which cancel out. Each individual lag is no longer than half the sampling period (1 ms), hence negligible. The cumulative lags are no longer than 48 ms for all subjects, which is also negligible. Nevertheless, only the LBio's Biosignal format preserves the exact original timestamps (10E-6 precision) of all samples and the original sampling frequencies.

Both include annotations of the activities, however LTBio bio signal files have better time resolution and include clinical data and demographic data as well.

Understanding protein sequence-function relationships is essential for advancing protein biology and engineering. However, fewer than 1% of known protein sequences have human-verified functions, and scientists continually update the set of possible functions. While deep learning methods have demonstrated promise for protein function prediction, current models are limited to predicting only those functions on which they were trained. Here, we introduce ProtNote, a multimodal deep learning model that leverages free-form text to enable both supervised and zero-shot protein function prediction. ProtNote not only maintains near state-of-the-art performance for annotations in its train set, but also generalizes to unseen and novel functions in zero-shot test settings. We envision that ProtNote will enhance protein function discovery by enabling scientists to use free text inputs, without restriction to predefined labels – a necessary capability for navigating the dynamic landscape of protein biology.

The ECOLANG Multimodal Corpus of adult-child and adult-adult conversation provides audiovisual recordings and annotation of multimodal communicative behaviours by English-speaking adults and children engaged in semi-naturalistic conversation.CorpusThe corpus provides audiovisual recordings and annotation of multimodal behaviours (speech transcription, gesture, object manipulation, and eye gaze) by British and American English-speaking adults engaged in semi-naturalistic conversation with their child (N = 38, children 3-4 years old) or a familiar adult (N = 31). Speakers were asked to talk about objects (familiar or unfamiliar) to their interlocutors both when the objects were physically present or absent. Thus, the corpus characterises the use of multimodal signals in social interaction and their modulations depending upon the age of the interlocutor (child or adult); whether the interlocutor is learning new concepts/words (unfamiliar or familiar objects) and whether they can see and manipulate (present or absent) the objects.ApplicationThe corpus provides ecologically-valid data about the distribution and cooccurrence of the multimodal signals for cognitive scientists and neuroscientists to address questions about real-world language learning and processing; and for computer scientists to develop more human-like artificial agents.Data access requires permission.To obtain permission to view or download the video data (either viewing in your browser or downloading to your computer), please download the user license at https://www.ucl.ac.uk/pals/sites/pals/files/eula_ecolang.pdf, fill in the form and return it to ecolang@ucl.ac.uk.
