Mish: A Self Regularized Non-Monotonic Neural Activation Function
Diganta Misra




BMVC, 2020
project / paper / abstract / bibtex

We propose Mish, a novel self-regularized non-monotonic activation function
which can be mathematically defined as:
f(x)=xtanh(softplus(x))f(x)=xtanh(softplus(x)). As activation functions play a
crucial role in the performance and training dynamics in neural networks, we
validated experimentally on several well-known benchmarks against the best
combinations of architectures and activation functions. We also observe that
data augmentation techniques have a favorable effect on benchmarks like
ImageNet-1k and MS-COCO across multiple architectures. For example, Mish
outperformed Leaky ReLU on YOLOv4 with a CSP-DarkNet-53 backbone on average
precision (APval50AP50val) by 2.1%2.1% in MS-COCO object detection and ReLU on
ResNet-50 on ImageNet-1k in Top-1 accuracy by ≈1%≈1% while keeping all other
network parameters and hyperparameters constant. Furthermore, we explore the
mathematical formulation of Mish in relation with the Swish family of functions
and propose an intuitive understanding on how the first derivative behavior may
be acting as a regularizer helping the optimization of deep neural networks.

Rotate to Attend: Convolutional Triplet Attention Module
Diganta Misra*, Trikay Nalamada*, Ajay Uppili Arasanipalai*, Qibin Hou




WACV, 2021
project / paper / supplementary / video / abstract / bibtex

Benefiting from the capability of building interdependencies among channels or
spatial locations, attention mechanisms have been extensively studied and
broadly used in a variety of computer vision tasks recently. In this paper, we
investigate light-weight but effective attention mechanisms and present triplet
attention, a novel method for computing attention weights by capturing
cross-dimension interaction using a three-branch structure. For an input tensor,
triplet attention builds inter-dimensional dependencies by the rotation
operation followed by residual transformations and encodes inter-channel and
spatial information with negligible computational overhead. Our method is simple
as well as efficient and can be easily plugged into classic backbone networks as
an add-on module. We demonstrate the effectiveness of our method on various
challenging tasks including image classification on ImageNet-1k and object
detection on MSCOCO and PASCAL VOC datasets. Furthermore, we provide extensive
insight into the performance of triplet attention by visually inspecting the
GradCAM and GradCAM++ results. The empirical evaluation of our method supports
our intuition on the importance of capturing dependencies across dimensions when
computing attention weights.

With the latest advances in deep learning, there has been a lot of focus on the
online learning paradigm due to its relevance in practical settings. Although
many methods have been investigated for optimal learning settings in scenarios
where the data stream is continuous over time, sparse networks training in such
settings have often been overlooked. In this paper, we explore the problem of
training a neural network with a target sparsity in a particular case of online
learning: the anytime learning at macroscale paradigm (ALMA). We propose a novel
way of progressive pruning, referred to as \textit{Anytime Progressive Pruning}
(APP); the proposed approach significantly outperforms the baseline dense and
Anytime OSP models across multiple architectures and datasets under short,
moderate, and long-sequence training. Our method, for example, shows an
improvement in accuracy of ≈7%≈7% and a reduction in the generalization gap by
≈22%≈22%, while being ≈1/3≈1/3 rd the size of the dense baseline model in
few-shot restricted imagenet training. We further observe interesting
nonmonotonic transitions in the generalization gap in the high number of
megabatches-based ALMA. The code and experiment dashboards can be accessed at
\url{https://github.com/landskape-ai/Progressive-Pruning} and

D2D2-Sparse: Navigating the low data learning regime with sparse networks   New!
Diganta Misra*, Niklas Nolte*, Lu Yin*




Under Review, 2023

abstract

Learning under constraints has been a fundamental avenue of research in deep
learning since the advent of modern deep neural networks. In parallel to the
upwards trajectory of scaling neural networks, one practical constraint that has
embodied efficient deep learning has been that of sparsity. Unstructured weight
sparsity has been the cornerstone of pioneering works in the space of pruning
and lottery ticket hypothesis. In this paper, we propose \textbf{D2D2-Sparse}, a
novel dual dynamic sparse learning system for low-data learning regime. Our
paper combines two popular constraints in deep learning namely sparsity and
low-data learning, often studied in disjoint paradigms, thus opening new
directions of research in sparsity. D2D2-Sparse outperforms standard iterative
pruning schema when coupled with standard deep networks in computer vision tasks
like image classification and in natural language processing like code
generation with no extra-overhead cost on inference. Compared to iterative
pruning, on 1818-th total data budget, D2D2-Sparse achieves a ≈≈ 4% top-1
accuracy boost for ResNet-18 on the CIFAR-100 classification task. Further, we
demonstrate the effectiveness of the proposed method in anytime learning
scenarios and provide extensive analysis into evolution of sparse masks in
D2D2-Sparse over the training process. Code, dashboard, and model weights will
be open-sourced for public access upon acceptance.

SPIRIT: Zero Shot Information Retrieval Domain Transfer with Soft Prompts   New!
Ethan Kim, Diganta Misra




Under Review, 2023

abstract

Dense information retrieval yields strong in-domain performance, but often
struggles with out-of-domain generalization, lagging be- hind unsupervised
methods. Retrieval tasks can vary across a num- ber of dimensions including
domain, query intent, and language. Using a single dense retrieval model for all
tasks often underper- forms lexical methods such as BM25. For practical
information retrieval systems, it is expensive to deploy a different model for
each task. Therefore, our motivation is to develop a cheap and effective
information retrieval model that maintains strong per- formance across different
domains while easily adapting to any new domain. Other approaches to domain
transfer in information retrieval rely on large auxiliary language models or
datasets and create a separate model for each task. In this work, we develop a
method utilizing prompt tuning to efficiently adapt dense retrievers with a
minimal amount of additional computation. By combining models trained on a
variety of different domains, we can effectively boost performance on a target
task in a new domain. Specifically, we train dense retrieval models using prompt
tuning on a large number of information retrieval tasks across diverse domains
and types of query intents. To adapt to a new domain, we create new prompt
embeddings by averaging the prompt embeddings from a set of source tasks
selected in an unsupervised manner. We evaluate zero-shot transfer performance
across a wide variety of information retrieval domains and show competitive
performance while lever- aging a minimal amount of compute. Notably, our SPIRIT
method achieves while being extremely lightweight and practical to deploy in
production.

Shapley Interactions for Complex Feature Attribution   New!
Divyansh Singhvi, Andrej Erkelens, Raghav Jain, Diganta Misra, Naomi Saphra




NeurIPS ATTRIB workshop, 2023

abstract

Feature interaction is an established approach to understanding complex patterns
of attribution in many models. In this paper, we use Shapley Taylor interaction
indices (STII) to analyze how linguistic structure influences language model
output in masked and auto-regressive language models (MLMs and ALMs). We find
that ALMs, and to a lesser degree MLMs, tend to combine pairs of tokens with
more nonlinear interactions if they co-occur in the same idiomatic multiword
expression. We also find that while ALMs tend to become more linear in their
interactions at greater positional distances, in MLMs this linearity is scaled
by syntactic distance, implying that the learned structure in MLMs relies more
on syntax than the recency-based structure favored natively by ALMs.

Mitigating Mode Collapse in Sparse Mixture of Experts   New!
Nizar Islah, Diganta Misra, Timothy Nest, Matthew Riemer




NeurIPS New in ML workshop, 2023

abstract

The recent success of Sparse Mixture-of-Experts (SMoEs) models has sparked
renewed interest in routed networks in deep learning. A prominent aspect of the
SMoE is the scaling of the number of total parameters in a model, effectively
increasing capacity while keeping computation costs similar to dense models.
Yet, these models pose optimization challenges as inputs are routed discretely
to experts in each layer. Often, a regularization term is added to the loss
function to penalize the imbalanced selection of experts. We aim to demonstrate
that the heuristic regularization strategies used in recent SMoEs, while
successful in some tasks, have significant limitations which we aim to address.
In multi-domain or multi-task settings, without explicit knowledge of the task
or domain, the network will suffer from a mode collapse-performance tradeoff, in
which some experts will receive significantly less training signal, or
performance on some tasks will suffer. Second, we derive a theoretical basis of
the various routing functions, with entropy-maximization as a common objective.
Third, we will demonstrate a first application of Generative Flow Networks
(GFlowNets) to SMoEs, with a state, policy, and action space, represented at a
particular layer of the model by the input, routing network, and sampling from
expert probabilities, respectively. We aim to show that SMoEs trained with the
Trajectory Balance objective from GFlowNet literature can achieve competitive
performance with state of the art routing methods, such as Switch Transformer,
and suffer less from expert collapse in multi-task (NYUv2, Pascal-Context) and
multi-domain (Omniglot) settings. This work lays some foundations for further
exploration of theoretically motivated approaches to routing in sparse MoEs.

Pruning CodeBERT for Improved Code-to-Text Efficiency   New!
Alex Gu, Ria Sonecha, Saaketh Vedantam, Bharat Runwal, Diganta Misra




SNN workshop at ICLR, 2023

abstract

The size and prevalence of large language models (LLMs) make them an apt target
for model compression. Most LLMs consist of a Transformer encoder and decoder,
which each have 6 to 12 layers of multiheaded self-attention blocks, along with
fully connected layers. This results in a large number of parameters, making
them quite expensive to train and query. Our work focuses on finding techniques
to prune CodeBERT, a specific LLM trained to work multimodally between text and
code. We explore the effects of structured and unstructured magnitude pruning on
the encoder layers of CodeBERT, evaluating on the task of generating natural
language comments from a piece of Ruby code.

Uncovering the Hidden Cost of Model Compression   New!
Diganta Misra, Agam Goyal, Bharat Runwal, Pin Yu Chen




Under Review, 2023

paper / abstract / bibtex

In the era of resource-intensive foundation models, efficient adaptation in
downstream tasks has become paramount. Visual Prompting (VP), inspired by
prompting in Large Language Models (LLMs), has emerged as a key transfer
learning method in computer vision. Aligned with the growing significance of
efficiency, research in model compression has become pivotal to alleviate the
computational burden in both training and deploying over-parameterized neural
networks. A key goal in model compression is the development of sparse models
capable of matching or surpassing the performance of their over-parameterized,
dense counterparts. While prior research has explored the impact of model
sparsity on transfer learning, its effects on visual prompting-based transfer
remain unclear. This study addresses this gap, revealing that model sparsity
adversely affects the performance of visual prompting-based transfer,
particularly in low-data-volume scenarios. Furthermore, our findings highlight
the negative influence of sparsity on the calibration of downstream
visual-prompted models. This empirical exploration calls for a nuanced
understanding beyond accuracy in sparse settings, opening avenues for further
research in Visual Prompting for sparse models.

Challenging Common Assumptions about Catastrophic Forgetting

Rodriguez, Laurent Charlin, Irina Rish




CoLLAs workshop, 2022
CoLLAs, 2023
paper / abstract / bibtex

Standard gradient descent algorithms applied to sequences of tasks are known to
produce catastrophic forgetting in deep neural networks. When trained on a new
task in a sequence, the model updates its parameters on the current task,
forgetting past knowledge. This article explores scenarios where we scale the
number of tasks in a finite environment. Those scenarios are composed of a long
sequence of tasks with reoccurring data. We show that in such setting,
stochastic gradient descent can learn, progress, and converge to a solution that
according to existing literature needs a continual learning algorithm. In other
words, we show that the model performs knowledge retention and accumulation
without specific memorization mechanisms. We propose a new experimentation
framework, SCoLe (Scaling Continual Learning), to study the knowledge retention
and accumulation of algorithms in potentially infinite sequences of tasks. To
explore this setting, we performed a large number of experiments on sequences of
1,000 tasks to better understand this new family of settings. We also propose a
slight modifications to the vanilla stochastic gradient descent to facilitate
continual learning in this setting. The SCoLe framework represents a good
simulation of practical training environments with reoccurring situations and
allows the study of convergence behavior in long sequences. Our experiments show
that previous results on short scenarios cannot always be extrapolated to longer
scenarios.

Beyond the Imitation Game: Quantifying and extrapolating the capabilities of
language models
Diganta Misra, Mukund Varma T., Multiple authors




TMLR, 2023
project / paper / abstract / bibtex

Language models demonstrate both quantitative improvement and new qualitative
capabilities with increasing scale. Despite their potentially transformative
impact, these new capabilities are as yet poorly characterized. In order to
inform future research, prepare for disruptive new model capabilities, and
ameliorate socially harmful effects, it is vital that we understand the present
and near-future capabilities and limitations of language models. To address this
challenge, we introduce the Beyond the Imitation Game benchmark (BIG-bench).
BIG-bench currently consists of 204 tasks, contributed by 442 authors across 132
institutions. Task topics are diverse, drawing problems from linguistics,
childhood development, math, common-sense reasoning, biology, physics, social
bias, software development, and beyond. BIG-bench focuses on tasks that are
believed to be beyond the capabilities of current language models. We evaluate
the behavior of OpenAI's GPT models, Google-internal dense transformer
architectures, and Switch-style sparse transformers on BIG-bench, across model
sizes spanning millions to hundreds of billions of parameters. In addition, a
team of human expert raters performed all tasks in order to provide a strong
baseline. Findings include: model performance and calibration both improve with
scale, but are poor in absolute terms (and when compared with rater
performance); performance is remarkably similar across model classes, though
with benefits from sparsity; tasks that improve gradually and predictably
commonly involve a large knowledge or memorization component, whereas tasks that
exhibit "breakthrough" behavior at a critical scale often involve multiple steps
or components, or brittle metrics; social bias typically increases with scale in
settings with ambiguous context, but this can be improved with prompting.

Genetic Algorithm Optimized Inkjet Printed Electromagnetic Absorber on Paper
Substrate
Diganta Misra, Rahul Pelluri, Vijay Kumar Verma, Bhargav Appasani, Nisha Gupta




IEEE AESPC, 2018
paper / abstract / bibtex

Printable electronics based electromagnetic absorbers are receiving increasing
attention of the electromagnetic community because of their unprecedented
advantages. This paper presents the design of printable electromagnetic
absorbers for the X band. The design of the absorber is optimized using the
Genetic Algorithm (GA) to enhance the absorptivity and the absorption bandwidth.
The design involves the placement of several square-shaped conductive ink at
optimal locations on the paper substrate such that desired absorption
characteristics are obtained. Simulations are carried out using the HFSS
simulation software. The optimized structure offers an absorptivity of more than
90% in the X band thereby proving to be a viable solution for stealth
applications.

Large-Scale Meta-Analysis of Genes Encoding Pattern in Wilson’s Disease   (Best
Paper Award)
Diganta Misra, Anurag Tiwari, Amrita Chaturvedi




Springer IC4S, 2018
paper / abstract / bibtex

In this paper, we propose an unsupervised learning approach with an objective to
understand gene expressions for analysis of Wilson’s disease in the liver of Mus
musculus organisms. We proceeded to obtain the best parameters for cluster
division to correctly classify gene expression sets so as to capture the effect
and characteristics of the disease in the genome levels of the organisms in the
best possible way. The clustering proved beneficial in capturing the correct
genetic analogy of Wilson’s disease. Analytical experiments were carried out
using various clustering algorithms and were evaluated using performance metrics
including silhouette score analysis and Calinski–Harabasz index.

Convoluted Cosmos: Classifying Galaxy Images Using Deep Learning
Diganta Misra, Sachi Nandan Mohanty, Mohit Agarwal, Suneet K Gupta




Springer ICDMAI, 2019 (Proceedings of the AISC)
paper / abstract / bibtex

In this paper, a deep learning-based approach has been developed to classify the
images of galaxies into three major categories, namely, elliptical, spiral, and
irregular. The classifier successfully classified the images with an accuracy of
97.3958%, which outperformed conventional classifiers like Support Vector
Machine and Naive Bayes. The convolutional neural network architecture involves
one input convolution layer having 16 filters, followed by 4 hidden layers, 1
penultimate dense layer, and an output Softmax layer. The model was trained on
4614 images for 200 epochs using NVIDIA-DGX-1 Tesla-V100 Supercomputer machine
and was subsequently tested on new images to evaluate its robustness and
accuracy.
