Methods that move towards less supervised scenarios are key for image segmentation, as dense labels demand significant human intervention. Generally, the annotation burden is mitigated by labeling datasets with weaker forms of supervision, e.g. image-level labels or bounding boxes. Another option are semi-supervised settings, that commonly leverage a few strong annotations and a huge number of unlabeled/weakly-labeled data. In this paper, we revisit semi-supervised segmentation schemes and narrow down significantly the annotation budget (in terms of total labeling time of the training set) compared to previous approaches. With a very simple pipeline, we demonstrate that at low annotation budgets, semi-supervised methods outperform by a wide margin weakly-supervised ones for both semantic and instance segmentation. Our approach also outperforms previous semi-supervised works at a much reduced labeling cost. We present results for the Pascal VOC benchmark and unify weakly and semi-supervised approaches by considering the total annotation budget, thus allowing a fairer comparison between methods.

This document presents a new neural network model called Linguistically-Informed Self-Attention (LISA) for semantic role labeling. LISA uses multi-task learning across several NLP tasks and incorporates syntactic information through multi-head self-attention. One attention head is trained to attend to syntactic parents using a biaffine parsing mechanism. Experiments show LISA achieves state-of-the-art performance on in-domain and out-of-domain semantic role labeling benchmarks, and incorporating a gold syntactic parse at test time provides further gains. Analysis indicates the largest source of errors is incorrectly labeled semantic role spans.
This document discusses using word embeddings to understand how data science skill sets have evolved over time. It presents two approaches to modeling word embeddings dynamically: 1) training embeddings together over time (dynamic embeddings), and 2) stitching together static embeddings trained on different time periods (static embeddings). The document demonstrates applying dynamic Bernoulli embeddings to career documents from 2016-2018. Analyses of embedding neighborhoods and drifting words identify shifting demand for certain skills like MBAs, PhDs, Tableau, and Hadoop in both small and large corpora.

Matrix Factorization with Knowledge Graph Propagation for Unsupervised Spoken...Yun-Nung (Vivian) Chen
This document describes a method for unsupervised spoken language understanding using matrix factorization with knowledge graph propagation. It discusses four main parts:
1) Ontology induction uses frame-semantic parsing to extract semantic slots from utterances.
2) Structure learning applies knowledge graph propagation to model relations between slots.
3) Spoken language understanding uses matrix factorization to model implicit semantics.
4) Experiments evaluate the method on a dialogue corpus, showing it improves over baselines at estimating semantic slot probabilities from utterances.

RAG-FUSION: A NEW TAKE ON RETRIEVALAUGMENTED GENERATIONkevig
Infineon has identified a need for engineers, account managers, and customers to rapidly obtain product
information. This problem is traditionally addressed with retrieval-augmented generation (RAG) chatbots,
but in this study, I evaluated the use of the newly popularized RAG-Fusion method. RAG-Fusion combines
RAG and reciprocal rank fusion (RRF) by generating multiple queries, reranking them with reciprocal
scores and fusing the documents and scores. Through manually evaluating answers on accuracy,
relevance, and comprehensiveness, I found that RAG-Fusion was able to provide accurate and
comprehensive answers due to the generated queries contextualizing the original query from various
perspectives. However, some answers strayed off topic when the generated queries' relevance to the
original query is insufficient. This research marks significant progress in artificial intelligence (AI) and
natural language processing (NLP) applications and demonstrates transformations in a global and multiindustry context

AI-powered Semantic SEO by Koray GUBURAnton Shulke
This document discusses optimizing websites and search engines using semantic techniques. It suggests that Website B, with more content, triples, accuracy and connected topics, would be more successful at satisfying search queries. It introduces the concept of topical authority to lower retrieval costs. Several techniques are proposed for language model optimization including fine-tuning, creating topical maps and semantic networks, and generating content informed by human effort and microsemantics. Cross-lingual embeddings and understanding word relationships are also discussed as ways to improve semantic search.
WordNet Based Online Reverse Dictionary with Improved Accuracy and Parts-of-S...IRJET Journal
This document proposes improvements to existing reverse dictionary systems. It discusses how current reverse dictionaries map user input phrases to words using semantic similarity, but sometimes return unrelated words. The proposed improvements are:
1. Refine the mapping process to consider candidate words that appear in at least two of the input terms' semantic sets, rather than requiring inclusion in all sets. This may return more relevant words.
2. When expanding queries using hypernyms, limit the level of generalization to avoid overly broad terms. Broad terms are more likely to appear in unrelated words' definitions.
3. Determine the part-of-speech of terms in the user's input phrase and return candidate words matching that part-of-speech,

Adria Recasens, DeepMind – Multi-modal self-supervised learning from videosCodiax
The document summarizes a talk on multi-modal self-supervised learning from videos. It discusses using multiple modalities like vision, audio and language from videos for self-supervised learning. It presents two models: 1) A Multi-Modal Versatile network that can take any modality as input and respects the specificity of each while enabling comparison. 2) BraVe which learns representations by regressing a broad representation of the whole video from a narrow view to leverage different augmentations and modalities. Both models achieve state-of-the-art results on downstream tasks, showing videos provide rich self-supervision and using additional context improves representation learning.

Investigation of the Effect of MFCC Variation on the Convolutional Neural Net...Md Rakibul Hasan
Md. Rakibul Hasan investigated the effect of Mel-frequency cepstral coefficient (MFCC) variation on convolutional neural network-based speech classification. He collected isolated vowel and word samples from Bengali speech and extracted MFCC features. A CNN model was trained on the MFCC data and achieved higher accuracy for vowel recognition compared to word recognition. Analysis showed vowels had less MFCC variation than words, contributing to their better classification performance by the CNN model.
Neural Models for Information RetrievalBhaskar Mitra
In the last few years, neural representation learning approaches have achieved very good performance on many natural language processing (NLP) tasks, such as language modelling and machine translation. This suggests that neural models may also yield significant performance improvements on information retrieval (IR) tasks, such as relevance ranking, addressing the query-document vocabulary mismatch problem by using semantic rather than lexical matching. IR tasks, however, are fundamentally different from NLP tasks leading to new challenges and opportunities for existing neural representation learning approaches for text.
In this talk, I will present my recent work on neural IR models. We begin with a discussion on learning good representations of text for retrieval. I will present visual intuitions about how different embeddings spaces capture different relationships between items, and their usefulness to different types of IR tasks. The second part of this talk is focused on the applications of deep neural architectures to the document ranking task.
This document discusses fixed point representations for high-quality speech and sound modification systems. It presents the STRAIGHT system, which uses fixed point algorithms to extract features such as fundamental frequency and excitation from speech.
